Diabetes changes oral microbiome that promotes gum disease
In a fascinating study on the relationship between diabetes and periodontal (or gum) disease, Janet Southerland and colleagues note that hyperglycemia leads to the formation of specific proteins and fats that promote inflammatory responses in the mouth. “Diabetes is an important risk factor for more severe and progressive periodontitis, infection or lesions resulting in the destruction of tissues and supporting bone that form the attachment around the tooth.” A new study, however, has discovered the reason why. It’s all got to do with the way that diabetes changes the oral microbiome – the community of microbial residents that lives in the mouth. Therefore, regular brushing and flossing, attention to one’s diet, and dental visits are key.
Shifting oral biomes
The study, published in the journal Cell Host & Microbe, compared the gum health of mice with and without diabetes, finding that the microbiome of hyperglycemic mice changed. Bacteria diversity became lower, and the result was gum disease, including a loss of bone supporting the teeth. These mice also had higher levels of IL-17, a molecule involved in the immune response and inflammation. The researchers were able to reduce bone loss in affected mice through the use of an IL-17 antibody. Currently, however, this treatment is not likely to be useful for humans. Researchers therefore insisted on blood sugar control and good oral hygiene for human beings with diabetes.
Your dentist can save your oral health
An interesting study involving 2.5 million people found that adults with diabetes are less likely to visit the dentist than those with pre-diabetes or those who don’t have diabetes. Why is that? Part of the problem is undoubtedly cost, as unlike countries like the USA, where those with lower earnings can rely on Medicaid to cover emergency and preventive oral health care, few medical aid schemes in South Africa cover dental health. The report also found ethnic disparities and concluded that single people and men were less likely to visit dentists than those in relationships and women, respectively.
How often should diabetics visit their dentist?
Diabetics are advised to visit their dentist at least once a year Preventive care ensure that teeth are clean and plaque does not cause gum tissue to separate, form pockets, and eventually lead to tooth and bone loss. It’s a good idea to see your dentist right away if you have any signs of gum disease or dry mouth… Be on the alert if your gums are inflamed and bleed, which happens with gingivitus.
Because microbiomes are different for people with diabetes, inflammation and gum disease can be more likely. It is important to take proactive measures to battle gum disease and tooth decay through daily hygiene and regular dental visits. Also be on the lookout for signs and symptoms of the beginning stages of gum disease.
When last did you go to the dentist?

From the community: “I don’t understand the whole ‘low carbs high fat or high protein’ idea – how do carbs, fat and protein work together? Is there a happy middle ground, or does it need to be all or nothing?” Wessel Jones
To understand what all the fuss is about, we need to look at the history of diabetes treatment. Treating diabetes (both Type 1 and Type 2) by lowering carbohydrates (carbs) has come and gone out of fashion over the last century. This debate is not a new one and it is probably not going to go away.
Before the invention of insulin, the only way for a diabetic to survive was to cut out the foods (carbs) affecting blood glucose. With the advent of insulin, the focus switched from lowering carbs to lowering fat to help reduce heart disease. Fast forward a couple of decades and we can see that we have failed in reducing obesity, diabetes or heart disease. It’s not as simple as just diet: it’s about physical activity, stress, diet and environment.
How do carbs work in the body?
What is quite simple is that carbs cause blood sugar to rise and the more carbs you eat, the higher the blood sugar goes. If a person wants to control their blood sugar, it’s a very good idea to reduce carbs. The big question is: how low do you go? A “low carbohydrate diet” can have anything from 20g to 130g of carbohydrate per day.
Remember: One portion of carb (a medium apple, a slice of bread) = 15g carb
The amount of carbs depends on the individual, their control, their medication and their weight. There is a growing amount of scientific evidence that low carb diets improve glucose control and help with weight loss.
Where do fat and protein fit in?
When carbs are cut, the amount of protein or fat (or both) go up. And this is where the debate heats up. The concern is not the low carb, but the increase in saturated fat or fat in general. Remember that not all fat is the enemy and there are good fats that play a very important role in the body.
A benefit of protein and fat is that in the immediate, they do not cause the same spikes in blood sugar. When you lower carb intake you have an immediate blood sugar lowering effect. When this happens, and you have fewer spikes and dips in blood sugar, your appetite is better controlled. The fuller you feel, the less likely you are to snack and the fewer kilojoules you consume. The fewer kilojoules you consume, the more likely you are to lose weight.
The problem with the low carb approach is that, like everything else, it needs to be a lifestyle. When you add carbs back into your diet you will put on weight, especially if you have increased your fat and/or protein. You can’t have it all: full fat products and also carbs. The most important goal is to increase your vegetable intake and try to eat as close to nature as possible. Eat foods in their most original form.
When it comes to deciding on the right ratio of carbs : fat : protein, work with a dietician. It may take time to find your correct balance and you need to be monitored properly with blood tests and possible medication adjustments.

From our community: “I get invited to lots of business meetings and workshops that are catered… Needless to say, none of the catering is healthy! What do I choose or how do I deal with this situation?” Rene Prinsloo.
Many of us consume at least half of our meals and snacks during work hours, which makes our food choices in catered meetings and workshops very important. Here are three steps to consider:
Step 1: Build your plate
- Aim to fill half your plate with vegetables or salad. Look out for vegetable skewers, veggie sides, crudités (chopped raw veg), soup or salads.
- Next, add a healthy carbohydrate: either a wholegrain/high fibre starch or a piece of fruit.
Look out for:
- Wholewheat bread
- A seeded roll
- Wholewheat pita
- Wholewheat pasta/noodles
- Wholewheat wrap
- Brown or basmati rice
- Fresh fruit
- For long-lasting brain and body power, add a source of protein.
Some good protein choices:
- Lean cold meats
- Grilled chicken
- Mini meatballs
- Legumes like beans or lentils
- Fish like tuna, sardines or pilchards
- Cottage cheese
- Boiled eggs
Sauces like low-fat mayonnaise, sweet chilli sauce, hummus or guacamole are optional but not essential.
- Deep-fried foods (like samoosas, spring rolls or vetkoek)
- Sausage rolls and pies
- Croissants, muffins or other pastries
Step 2: Choose portions with caution
- Be sure to start the day with a balanced breakfast and keep healthy snacks or a packed lunch on hand to avoid arriving at a meeting hungry.
- Use smaller plates and serving utensils to help manage how much you dish up.
- Sit far away from the food to avoid “picking”.
- Use the size of your hand to determine sensible and healthy portion sizes and curb overeating:
- A fistful is equal to one cup and can be used to estimate the portion size for carbohydrates (starches and fruits).
- The size of the palm of your hand can be used to estimate the portion size for protein. For a stew, curry or casserole this would be about half a cup.
- The tip of the thumb is equivalent to one teaspoon and can be used to estimate the portion size for all oils, butter or mayonnaise.
- The thumb can also be used to estimate the portion size for peanut butter or hard cheese.
Step 3: Carefully consider your choice of drink:
Some good choices are:
- Still or sparkling water
- Tea or coffee
- Vegetable juice
- Low-fat milk
- Sugar-free fizzy drinks
Ketones and ketoacidosis are often mentioned in relation to diabetes, but what are they exactly?
- Ketones result when your body burns fat for energy.
- They are formed when the body doesn’t have enough insulin to use glucose for fuel.
- A urine test is traditionally used to test for ketones: some blood glucose meters can also test for ketones.
- Ketones make the blood more acidic.
- Ketones in the urine combined with high blood sugar are a warning sign that your diabetes isn’t under control.
- Diabetic ketoacidosis (DKA) is caused by a combination of high blood sugar that causes a rise in ketones. The ketones are an indication of how acidotic the patient is, and the acidosis can be fatal.
- DKA is serious and can lead to diabetic coma.
- DKA is rare in Type 2 diabetics and more common in Type 1 diabetics with uncontrolled blood sugar.
- Symptoms of DKA are thirst, frequent urination, high blood glucose, constant tiredness, nausea, vomiting, abdominal pain, dry/flushed skin, breathing difficulty and confusion.
- If these symptoms ring a bell, see a doctor as soon as possible to get your blood sugar under control.

From our community: “As the mom of a diabetic child, I’m constantly wondering what to make her that is delicious but won’t spike her blood sugar. Could you give me some basic guidelines please?” Bernadette Simons.
As a mother of three (constantly hungry) young boys I am kept on my toes when it comes to healthy eating. Although my children are not diabetic, I practice “diabetes-friendly” eating in my household. The bottom line is that you want your children to eat real, whole foods. This means no foods that are manufactured, processed and refined: time for a cupboard clear-out!
For children with diabetes, you need to make meals novel, colourful and exciting, while reducing refined carbohydrates and harmful fats. It’s important to break away from the rut of cereal for breakfast, sandwich for lunch and one-pot meal for dinner. Parents need to constantly focus on increasing fresh foods and not wait for dinner to try and make up the daily vegetable intake…
Here are some menu options:
- Bring back eggs for breakfast! Make eggs more interesting and nutritious by adding vegetables and baking in a muffin tray as mini crustless quiches. Serve with chopped strawberries or other brightly coloured fruit.
- Try making your own cereal out of nuts and seeds, coconut shavings and some rolled oats. This can be eaten with plain yoghurt or milk. Use vanilla, cinnamon and half a grated apple to sweeten it naturally.
- Move away from a daily sandwich for lunch. Try choosing other low GI starch like baby potatoes or corn on the cob.
- Add some protein – chicken drumsticks, hard-boiled eggs, meatballs, homemade fish cakes or cheese. Remember protein makes you feel fuller for longer and doesn’t spike blood sugar levels.
- Add a small amount of colourful fruit like a fruit kebab or fruit salad.
- All lunchboxes should have vegetables! If your child doesn’t like salad, give some cucumber and carrot sticks, baby tomato kebabs or cucumber sandwiches (two slices of cucumber with cheese or cream cheese in the middle).
- Most traditional South African dinners are one-pot meals like curry, stew, cottage pie or spaghetti bolognaise that are high in starch and low in vegetables. Try adding more vegetables to stew, curries and mince. Make the mashed potatoes with added cauliflower, add lentils to brown rice, and use baby marrow or aubergine instead of pasta.
- Always serve dinner with vegetables on the side. Raw carrot sticks, sliced cucumber or snap peas are kid-friendly. Children need to get used to eating vegetables that are not hidden in food but out in plain sight!
Remember: Children learn eating habits from their parents so you need to set the example. Tastebuds are influenced early on by processed foods with hidden sugars and fats, so it’s up to you to encourage your kids to eat – and love – real food.
Hypoglycemic episodes (hypos) can be a scary experience for all involved: here’s what you need to know to deal with one.
- A hypo is a sudden low blood sugar episode.
- The optimal blood glucose range is 4 to 7mmol/l. With a hypo, blood glucose levels are usually lower than 3mmol/l.
- Initial symptoms are nervousness, sweating, intense hunger, trembling, weakness, palpitations, or trouble speaking (depending on the person).
- The best thing to treat a hypo is fast-acting carbohydrates: 15-20g of sugary carb (a few sweets, 2 tablespoons of raisins, a tablespoon of honey or half a cup of fruit juice).
- The key is to catch low blood sugar early – as soon as it starts dropping – and treat it with a small dose of something sweet.
- If blood glucose drops too low it can get to the stage where the brain is not getting enough glucose.
- Symptoms of this are confusion, drowsiness, changes in behaviour, seizure and eventually coma.
- In case of a severe hypo, a glucagon emergency kit may be necessary. This once-off injection instantly raises the blood sugar, and is particularly useful when the person with diabetes is unconscious or unable to swallow.
- Notify all those close to you what to do in an emergency and how to use a glucagon injection.
- Test often to keep your levels as well controlled as possible.
Meet Shane Casserley: a Type 1 diabetic who is also juggling coeliac disease and ADD… while living his best life.
When were you diagnosed with Type 1 diabetes?
When I was 8 years old years. I am now 22.
Was your diagnosis a shock?
A huge shock. I was completely freaked out. I was hospitalised straight away and had to stay in hospital to learn to give my own injections and I was visited by a dietician to adjust my diet. After the initial shock wore off I went into depression.
When were you diagnosed with coeliac disease and ADD?
In 2011, when I was 16 years old.
How do they affect your diabetes?
They don’t affect my diabetes in any way but it was another huge diet adjustment because when you have coeliac disease you are not allowed to eat anything containing wheat or gluten. The ADD also does not affect the diabetes directly but indirectly it is a lot more difficult to remember to check your sugar regularly and give insulin when you eat.
How did you become interested in fitness?
When I was going through a rough time, a friend offered to take me with him to gym. It made me feel so good that I have been hooked ever since.
Why do you want to be a personal trainer?
Going to gym and changing my diet greatly improved my health and self image, and gave me the confidence that I lacked. I would like to do the same for other people, especially for diabetics who are battling.
How do you think regular exercise helps people with diabetes?
It has a big impact on stabilising sugar and thereby lessening the risk of future complications. At the same time, it increases your endorphins, which makes a person feel good psychologically and decreases depression.
What advice do you have for other diabetics who are struggling?
The most important thing is to accept that you have it and you can’t change it and rather learn to adapt to it. Once you have accepted it and you start eating right, exercising regularly and keeping a good check on your sugar readings, then you can lead a normal life. It is always good to get support from other diabetics.
When Vickie de Beer’s son Lucca was diagnosed with Type 1 diabetes, she started a journey that ended with her publishing an award-winning cookbook and lifestyle guide: The Low Carb Solution for Diabetics.
Looking back, what do you wish you’d known when Lucca was first diagnosed with Type 1 diabetes?
That insulin takes much longer to reach the blood stream than we were told. I had a lot of anxiety about Lucca going into a hypo after eating, and it was completely unnecessary. I also wish I knew what a huge impact carbohydrates had on his blood sugar! We did carb count and test and inject diligently, but there were always unexplained highs and lows that frustrated me and made Lucca feel awful.
What inspired you to write The Low Carb Solution for Diabetics?
We have always, from the first day, taken Lucca’s diabetes seriously. We did everything the doctors and dietician told us. We adapted our diet to eating only low GI foods and tested Lucca’s blood sugars diligently. Every time we went to the doctor they congratulated us on his great HbA1c result and said that we were doing everything possible for Lucca’s health.
The doctor always said that the next step would be to control the extreme fluctuations between high spikes and lows in Lucca’s blood sugar. I could never get clear information on how we were supposed do that though, apart from doing what we were already doing. About a year ago I met Prof Tim Noakes at the book launch of Real Meal Revolution. We significantly reduced our carbohydrate intake, but did not remove carbohydrate completely from our diet.
I didn’t understand how we could remove all the carbohydrates from Lucca’s diet as suggested by the LCHF (Low Carb High Fat) movement. We were taught that children needed carbohydrates for energy, growth and brain function and I also knew that Lucca needed to get insulin. If we took away the carbohydrates how would he get the insulin he needed? I still gave the children small amounts of Low GI carbs like brown rice and brown pasta with their evening meals. Lucca’s blood sugar did not improve significantly – I would say that we were on a moderate carb diet.
A few months ago I made contact with a group in the USA that follow a low carb high protein (not high fat) diet with great success in managing steady blood glucose levels in Type I diabetic children. This way of managing diabetes is based on a book: Dr Bernstein’s Diabetic Solution. Dr Bernstein has been a Type 1 diabetic for 69 years. After reading his book and studying various other low carb websites and books, we decided to change the way we eat.
Do you have any tips for people who feel overwhelmed at the thought of changing their way of eating?
Do it gradually. We started with breakfast (because the boys love bacon!) and then did dinners – lunchboxes were the last!
What advice would you offer to people living with diabetes who are struggling?
Diabetes is in the details. The best tool is to test constantly and diligently. The bottom line is that cutting carbs makes diabetes easier to manage. All the hundreds of reasons I used to give to explain Lucca’s unstable sugar – the heat, stress, tiredness – it was always the carbs!
What makes your life sweet?
Hugs from my boys! Playing board games with them (and winning), swimming and braaing with them, reading with them… The fact that Lucca’s blood sugar is under control has changed our lives. We had a lot of anxiety in our life beforehand. Although we still test and inject diligently, the anxiety is gone. I think we have finally taken control of diabetes, and diabetes has lost its control over us.

From the community: “Being both diabetic and pregnant makes it difficult to know what to eat – there are so many things I have to avoid! And I’ve been craving sweet things. Any advice?” Sameshnie Naidoo.
The diet for pregnant women with diabetes should be a healthy, well-balanced eating plan aimed at supporting the pregnancy and promoting blood sugar control. This is essential for the wellbeing of both mom and baby.
Of course, pregnancy and diabetes means that there are more foods on the “Do Not Eat” list, as your normal diabetic diet has a new list of things to avoid. But bear in mind that it’s only for nine months, and that it’s for the best possible cause: your healthy child.
Foods to avoid:
Here’s a list of foods that you shouldn’t eat when you’re pregnant because they pose a potential food safety risk and might make you ill or harm your baby.
- Soft cheeses e.g. brie, camembert, and blue-veined cheeses unless the label says they are made with pasteurised milk.
- Processed cold meats or deli meats unless they are reheated until steaming hot.
- Refrigerated paté or meat spreads (canned options can be eaten).
- Refrigerated smoked seafood unless as an ingredient in a cooked dish e.g. a casserole.
- Raw or partially cooked eggs and dishes that contain these e.g. homemade mayonnaise.
- Raw or undercooked meat and poultry
- Unpasteurised juice
- Raw sprouts
- Raw or undercooked fish or shellfish
- The American Academy of Nutrition and Dietetics (AND) recommends pregnant women avoid fish high in mercury e.g. shark, swordfish, marlin. And limit intake of fish and shellfish lower in mercury e.g. prawns, canned light tuna and salmon, to 360g or less per week.
The good news? You don’t need to give up caffeine entirely. The AND recommends keeping your intake below 300mg/day, which is about one or two servings of coffee or tea. And of course rooibos is naturally caffeine free, so you can have as much as you like!
Being both diabetic and pregnant can feel restrictive from a diet point of view… When you’re lacking motivation, just remember that everything you eat your baby is eating too: so put down the junk food and pick up a carrot!
A note on cravings:
Whether it’s pickles and ice cream or other odd combinations, both cravings and food aversions are common during pregnancy. Although the exact cause is unknown, taste perceptions may change with hormonal changes. Cravings are generally harmless*, unless foods you crave replace more nutritious foods, or all you want is junk food. If broccoli loses its appeal, for example, substitute another vegetable that you enjoy and tolerate.
*Cravings for non-food substances like sand or chalk (a condition called pica) can be dangerous as they contain lead or other toxic substances. If you’re craving non-food items, consult your doctor.

From the community: “My wife and I love having friends over for sundowners but never know what drinks to offer and what snacks to serve so that I can actually enjoy myself too. Any advice?” Riyaaz Benjamin.
Luckily, there is a way to enjoy (guilt-free) sundowners… It just takes a little planning. Let’s take a look at the when, what and where of it.
The main problem with sundowners lies with the timing. As the name suggests, they usually occur long after lunch and just before supper. This means that you may arrive hungry and tired with low blood sugar levels: a recipe for overeating, drinking (sugary) alcohol on an empty stomach, and filling up on unhealthy snack food. After sundowners, you may then go for supper, which means even more food and alcohol.
The key? Sundowners are best handled when prepared. Make sure you have an afternoon snack just before arriving (preferably one that contains protein to help stabilise blood sugar levels). Upfront, decide to either have the snacks as a replacement dinner (only a good idea if there are healthy snack options) or hold back and leave room for a light supper.
What is being dished up? The good news is that sundowner snacks are usually savoury and not sweet. The bad news is that savoury snacks – like chips and cream dip, sausage rolls and salty peanuts – are often high in starch and fat. Try to choose the healthiest options on the table, and don’t forget to dish up a plate rather than snacking so that you know exactly how much you’re eating.
Sundowners are also synonymous with cocktails (not the right choice of drink for anyone with diabetes!) When it comes to alcohol, good options are light beer, a wine spritzer made with Sprite Zero or soda water, or single spirit tots with diet mixers. Sparkling water with ice, lemon and cucumber is a refreshing drink if you’re not in the mood for alcohol.
Healthy snack ideas:
- Lean proteins like nuts, lean biltong and grilled strips of chicken or beef.
- Fresh vegetables like cucumber strips, baby carrots, baby tomatoes and celery sticks, served with a low-fat cottage cheese, avo or salsa dip.
The last thing to consider is where the sundowners are being held. If you’re hosting or going to a friend’s house, you can simply bring along what you would prefer to eat and drink. Restaurants can be more challenging, but easily overcome with a bit of forward planning. Call the restaurant beforehand and make sure that there are snacks or drinks on hand that you can enjoy. Most restaurants are more than willing to help – if not, at least you know and can plan for the evening.
Having diabetes doesn’t mean you can’t enjoy a cold drink and a delicious snack as the sun goes down, it just means you need to forward plan a little to enjoy it!
Keeping your diabetes in check as you get older is not only possible, but important. Here’s what you need to remember.
- Diet is vital: be sure to eat as balanced a diet as possible. Not eating the right kind of food or often enough can result in low blood sugar. Drinking plenty of water is also important.
- The average HbA1c in the elderly population in SA is within national guidelines at around 7.3. What’s yours?
- Be prepared and always have at least 3 days of supplies on hand for testing and treating your diabetes.
- Hypos (low blood sugar) are a risk, especially in Type 2 diabetics who are on SUs (sulphonylureas). Severe hypos can result in comas, so it’s important to know how to treat them.
- Always keep a glucagon pen on hand for hypo emergencies (and make sure you’ve told someone close to you how to use it).
- Controlling Type 2 diabetes with Glucophage or Galvus can have a life-changing effect.
- It’s important to have regular blood pressure and cholesterol tests, and annual kidney, eye, teeth and feet check-ups.
- It’s a good idea for any diabetics over 65 years old to have a pneumonia vaccine shot. An annual flu shot is also beneficial.
- Keep active as it helps with mobility, balance, strength, mental wellbeing and insulin sensitivity.
- Studies show that older diabetics are more compliant than teenagers, the newly diagnosed, and even pregnant diabetics.

Ajita Ratanjee is a registered dietician on the Sweet Life Panel of Experts. She shares some of her diabetes dietary tips with us today.
Blood sugar control is of the utmost importance for a diabetic. To date, many diabetics have a challenge keeping their glucose levels controlled. A combination of the following 3 factors ensure good glucose control:
- Use of medication (oral meds or insulin injections)
Foods to avoid
Most diabetics I meet are familiar with the “AVOID” list of foods. These are the obvious sugars e.g. Sugar, sweets and chocolates, sugary cooldrinks, cakes, pastries, biscuits, ice-cream, puddings etc. If you’re a diabetic and continue consuming the above list, then you are literally accelerating the chances of complications of diabetes: nerve damage, blurred vision, kidney failure, sores on feet etc.
However there are many who are compliant with the “AVOID” list yet may still find that their blood sugar levels remain elevated. Many years of clinical experience working with diabetics has allowed me to create a shortlist of other foods that are most likely spiking your blood sugar and you’re not even aware they are the cause. They are “healthy” food choices; however they tend to spike blood sugar and are not the best choice for a diabetic.
Other foods that spike blood sugar
These foods should also be avoided:
- any 100% fruit juice,
- dried fruit,
- energy drinks,
- flavoured bottle water,
- energy bars,
- muesli (containing nuts and dried fruit),
- popcorn, and
100% Juices and dried fruits are a concentrated source of natural sugar resulting in blood sugar elevation. Most energy drinks are loaded with sugar and are not suitable for diabetics. Energy bars tend to be marketed as low-fat, however that is not the same as sugar free (at all!)
The important thing to remember is that a diabetic should be aware of all foods that elevate bloods sugar levels. Grains, fruit and vegetables are all healthy but they need to be eaten in the correct portions to keep sugar controlled. Protein helps to stabilize sugar and thus an extra serving of meat / fish / chicken / egg etc. will not elevate glucose as much as an additional slice of bread / rice / potato.
The magic diabetes diet lies in the correct proportion of carb to protein at meals and snacks, and the correct portions at every meal and snack.
Choosing the right food
Fatty fish are high in omega 3 – tuna, sardine, salmon and mackerel are high in essential fatty acid. These are protective towards cardiovascular health and have anti-inflammatory properties. Diabetics are at high risk of heart disease thus omega 3 supplements are highly recommended. Make sure that you use good quality omega 3 that is heavy metal free.
Alcohol is metabolized as a sugar so plan in your glass of wine (preferable red and dry) or whiskey.
My key message in a nutshell would be – it’s not just about “no sugar” but rather getting the carbohydrate and protein balance. Test your glucose regularly; at different times of the day. This enables you to monitor your control throughout the day. Test your sugar before a meal or 2 hours after a main meal. Keep a record of your blood sugar readings.
At Easy Health Wellness we assist our clients by teaching them how to exchange carbs and how to count carbs to ensure that they always are in balance at each meal and snack, and they can enjoy variety in their eating plans. We also stock a fabulous range of sugar-free products to support our diabetic’s client needs.
The diabetic way of eating is a very healthy way of eating. We can all do with avoiding the refined carbs and eating regularly.

From our community: “I know that as a diabetic I should always try and be good, but sometimes it’s hard… What can I snack on without feeling too guilty about it (but that will also be a treat)?” Charne Smith.
A treat is something that tastes great, is normally high in fat and refined carbohydrate, and is eaten to either celebrate or make you feel better… But how do you have your treat and prevent it from totally messing up your blood sugar levels for the day?
Treats are not forbidden, but they should not be too often or too big. It all comes down to self-control and portion control. The occasional block or two of chocolate should not mean disaster for your blood sugar: it’s when you eat the whole slab that things spiral out of control. Everything in moderation is the key.
If you battle with cravings, you need to understand that the last bite never tastes as good as the first bite. The feel good rush you get from the first bite of a treat starts to fade as you continue eating, but your blood sugar levels start to increase.
What does this mean? You only need a small amount to feel like you’ve had a treat. You don’t need the whole slab, packet, bowl or slice…
How to cheat:
- Split a dessert with your partner. It might drive them nuts, but it will keep your blood sugar and weight down. Better yet, plan ahead and choose a light main course so that you can have a small dessert on those special evenings out.
- Choose biscuits and cakes that don’t have icing, or remove the icing and jam from cakes. Icing has twice the amount of sugar as the cake or biscuit.
- Choose a dessert like apple crumble (without the ice-cream or cream) or two small scoops of ice-cream. Just remember to keep portions small.
- Spoil yourself with some good diabetic-friendly ice-cream (low fat/low sugar), lite custard and diabetic friendly puddings.
- Opt for small “bite” sized chocolates or chocolates with wafer inside (e.g. Kit Kat Fingers).
- Dark chocolate with a high percentage of cocoa is better for you as it is higher in antioxidants. Dark chocolate is also bitter so people tend to eat less of it: usually a block or two is enough.
- Salt and vinegar popcorn instead of crisps will keep your fat content low and help with salt cravings. When going to the movies, choose a small popcorn and a diet drink.
Remember: Spoiling yourself on the odd occasion is allowed. Always test your blood sugar levels to see how they react and you will learn to better control these situations.

How long have you been diabetic? 25 years
How long have you been on the pump? 5 years
What made you decide to get an insulin pump?
I battled to get my blood glucose under control on multiple daily injections, especially when doing sports. It was before my first 94.7 cycle challenge that my doctor suggested insulin pump therapy. It has changed my life! I can’t imagine life without my Accu-Chek Combo pump.
What do you love about the pump?
Everything! It helps me to live life the way I want to. I love the discreetness of it – I can give a bolus in a meeting or when going out with my friends, without anyone noticing.
What are some of the challenges?
The first two months were difficult to get used to sleeping with the pump, but now I don’t even realize that I’m wearing it. The challenge is more with diabetes – not the pump. It’s important to realise that insulin pump therapy is not taking the condition away. There are so many variables in diabetes, and that will always be a challenge.
When should someone consider getting an insulin pump?
- If they are experiencing severe hypoglycaemic (low blood sugar) episodes despite careful management.
- If they are on multiple daily injections, following a meal plan, testing their blood glucose levels 4 times a day, and still not getting target HbA1c results.
- If they have irregular eating, working and resting times.
Insulin pump therapy won’t work for those who aren’t committed to it, and there isn’t enough evidence to recommend it for Type 2 diabetics.

FAQ about the insulin pump from our community:
What is an insulin pump?
- Insulin pumps are portable devices attached to the body that deliver constant amounts of rapid or short acting insulin via an infusion set.
- The pump tries to mimic the release of insulin from a normal pancreas, but you have to tell it how much insulin to inject.
- It delivers insulin in two ways: a basal rate which is a continuous, small trickle of insulin that keeps blood glucose stable between meals and overnight; and a bolus rate, which is a much higher rate of insulin taken before eating to “cover” the food you plan to eat or to correct a high blood glucose level.
- Because the insulin pump stays connected to the body, it allows the wearer to change the amount of insulin they take with the press of a few buttons at any time of day. You can also program in a higher or lower rate of insulin delivery at a chosen time – when sleeping or doing sports, for instance.
Where do you buy an insulin pump and how much does it cost?
You need to be a patient at one of the accredited pump centres in South Africa. Your doctor will decide if you are a pump candidate according to the Association of Clinical Endocrinologists of South Africa (ACE-SA) guidelines. If you are, you will need a script to claim the pump through your medical aid, or buy it cash from one of the supplying pharmacies.
What are the advantages and disadvantages of using an insulin pump?
Insulin pump therapy improves metabolic control while giving you greater freedom and a better quality of life.
- Your metabolism stays more stable, with better HbA1c values and fewer low blood sugar episodes.
- You can be more flexible in your eating, if you understand the concept of carbohydrate counting.
- You can participate in sports whenever you feel like it — without having to plan in advance
Disadvantages are that you have too much freedom in making food choices, and that there is a risk of diabetic ketoacidosis (DKA) from pump malfunction or absorption problems.
Remember: Deciding on insulin pump therapy is not a simple decision and should be carefully discussed with your healthcare team.
Will my blood sugar control be better if I use an insulin pump?
It all depends on you. You can wear a pump and it can have no impact on your blood sugar. Or you can use a pump, and with the right settings, motivation and help from your healthcare team, you can have better blood sugar control.
Will I still have to test my blood sugar as much?
A pump patient needs to be a motivated patient who tests regularly, around 4 times a day.
Are there insulin pumps that have a Continuous Glucose Meter attached?
Yes there are – it’s a good idea to discuss with your healthcare team which pump would best suit your needs
How would the insulin pump be used for sports? Are there special casings made or will I have to play without it?
You can engage in any kind of physical activity while wearing an insulin pump. But for sports with intensive body contact and water sports we recommend temporarily disconnecting the insulin pump (not for longer than 1 hour). Special cases and pouches can protect the pump, but it’s always a good idea to insure it as well.
At what age can you put a child on the insulin pump and how easy is it for them to adapt?
I would say at any age, but it’s best to get advice from your pediatric endocrinologist. Children often adapt the easiest of all age groups to insulin pump therapy.
What is the risk of infection?
If you follow the right hygiene steps, the risks are low. You should always disinfect the pump site before inserting the infusion set. It is also critical to replace the infusion set every three days.
How much is an insulin pump with and without medical aid?
That depends on the type of medical aid plan and whether the medical aid covers the costs fully or partly. It would be best to discuss this with your healthcare team or your medical aid. If your doctor agrees that pump therapy is the best option for you, they will send an application to the medical aid.
