Spotlight on... diabetic diets

What is diabetes?

Diabetes is a lifelong condition caused by a failure of the blood sugar regulation mechanism in the body. This is controlled by a hormone called insulin. Diabetes results when the pancreas does not secrete enough insulin or cells of the body become resistant to insulin so blood sugar levels are not controlled as they should be. Without the proper function of insulin, sugar cannot enter muscle or fat cells, causing serious secondary complications such as heart disease, stroke, kidney disease, neuropathy and other complications.

 

Type 1 diabetes

Insulin dependent, less common and usually develops before the age of 30.

Type 1 diabetes occurs when the pancreas stops producing insulin. The exact cause is unknown but some believe that it is an autoimmune response in which the body attacks its own pancreatic cells. People with Type 1 diabetes must take insulin for life.

 

Type 2 diabetes

Non-insulin dependent, used to be most common in later life but is becoming increasingly more prevalent in younger generation largely due to an increase in obesity.

In Type 2 diabetes, the pancreas still produces insulin, but either it is not producing enough or the body does not respond to it properly. The most common cause of type 2 diabetes is obesity. In many cases, Type 2 diabetes can be avoided through eating a healthy, balanced diet and taking regular exercise and often can be controlled in the same way if diagnosed. However, some cases will require medication and your doctor should be the one to determine whether this is necessary.

Recent research has reported interesting evidence to support the reversal of type 2 diabetes. Research funded by Diabetes UK and performed by a team at Newcastle University reported that type 2 diabetes can be reversed by an extremely low-calorie diet (600 kcals per day).

This diet is extreme and Diabetes UK strongly recommends that such a drastic diet is only undertaken under professional medical supervision. People with diabetes who want to lose weight should consult their GP before undertaking any new eating plan.

...a note on Gestational diabetesGestational diabetes

Gestational diabetes is a type of diabetes that affects women during pregnancy, when some women have slightly higher than normal levels of glucose in their blood and their body cannot produce enough insulin to transport it all into the cells.

 

Symptoms

Symptoms of diabetes can include tiredness, thirst, frequent urination and skin infections. A full list of symptoms can be found at diabetes.co.uk . Diabetes must always be controlled under the management of a doctor. For further advice and information see: diabetes.org.uk


Health Implications

People with diabetes of either Type 1 or 2 have a higher chance of developing a range of health conditions including heart disease, stroke, high blood pressure, circulation problems, nerve damage and damage to the kidneys and eyes. If you are overweight then losing this excess weight healthily and steadily can have a very positive effect on blood sugar levels and can reduce the risk of developing Type 2 diabetes. It's also particularly important to build up a good exercise routine as this will help the body maintain good blood sugar levels.

 

weight managementFood choices for diabetics

Dietary modification is fundamental to the successful management of both Type 1 and Type 2 diabetes, though making sensible choices will mean you can continue to enjoy a wide range of foods. It's imperative that weight is kept within the normal range. The dietary guidelines are very similar to those recommended for a healthy lifestyle: eat less sugar and fat, include more fibre-rich starchy foods and more fruit and vegetables with moderate amounts of meat, fish, milk and dairy. Choosing the right foods can make a big difference and eating regularly helps to ensure blood sugar levels do not fluctuate too much.

 

Foods to eat

- Starchy carbohydrates provide energy and help maintain and control blood glucose levels so should factor in every meal, though portion sizes and carb intake should be discussed with a dietician to ensure you are eating to your individual needs. Look for wholemeal or wholegrain breads, high fibre breakfast cereals, wholemeal pasta and brown rice.

- Fibre can slow the rate at which the starch and sugar in foods enter the bloodstream. It can also help manage cholesterol levels as part of a balanced diet. This kind of soluble fibre is found in oats, pulses, fruit and vegetables.

- Whether you are taking insulin or not, stick to low GI foods (see below for suggestions).

- Magnesium, chromium, zinc and vitamin B3 all help to stabilise blood sugar. Eat plenty of green vegetables, whole grains, dairy foods, brewer's yeast, seafood and pulses to ensure adequate amounts of these micronutrients.

- Maintain your hydration levels with water, herbal teas etc. but avoid squash and sugary drinks.

 

Foods to avoidFoods to avoid

- Diabetes is linked to a higher risk of cardiovascular disease so the same heart friendly healthy eating principles apply. See our Spotlight on heart disease article

- If you decide to drink alcohol, avoid drinking more than the recommended amount, and never drink alcohol on an empty stomach. Men and women are advised not to reguarly drink more than 14 units a week. Depending on the amount you drink, alcohol can cause either high or low blood glucose levels (hyperglycaemia or hypoglycaemia). Drinking alcohol may also affect your ability to carry out insulin treatment or blood glucose monitoring, so always be careful not to drink too much.

- Minimise refined carbohydrates and enjoy low GI foods instead.

Moderate your intake of the following:

  • Over-ripe bananas
  • Fruit yogurts and desserts high in sugar
  • Fruit juices
  • Dried figs & dates
  • White bread, baguettes and bagels
  • Cream crackers & white rice cakes
  • Iced cakes & pastries
  • Scones, crumpets and waffles
  • Sweet pies
  • Fruit canned in syrup
  • Breakfast cereals containing sugar
  • Baked & mashed potatoes and chips
  • White rice
  • Corn & rice pasta
  • Pizza
  • Popcorn
  • High sugar jams & jellies
  • Crisps and other potato & corn snacks
  • Fruit drinks containing added sugar
  • Fizzy drinks containing sugar
  • Sweets & chocolate bars
  • Thickened soups
  • Table sugar
  • Ice cream containing glucose syrup or high levels of other sugars

There's quite a lot of research which now proves beyond doubt that dieting by pregnant women (especially in the forst trimester when most docotrs tell you not to put on weight) lead to the child having a predisposition to gain weight faster on normal levels of food. Dieting can also 'kick-start' diabetes in children. So it's not simply 'obesity causes diabetes' in fact it doesn't - but what causes the obesity in the first place - and it begin in the womb.

try testing your blood sugar after eating meals containing the 'complex' carbs, e.g brown rice, wholemeal pasta, recommended. You may find, like me, that they push up your blood glucose levels just as much, and as quickly, as white rice, white pasta. It is these high levels of glucose in your blood that cause damage. I go for half a plate of veg (no starchy root veg), very small spoon of a carb, then some protein, e.g. Chicken, which can have a good dollop of something fatty like creme fraiche mixed with it. My doctor says my HBA1c levels are now not showing signs that I have diabetes (though of course I still do)

Carrots appear in the diabetics' list of what not to eat. Should we really be eating the Puy lentil, spiced roast carrot and feta salad recommended above?

If basmati rice and brown rice are on the acceptable substitute list, why are chick peas and lentils given for accompaniments for curry when rice is more normal and in my opinion more acceptable, please?
