5 Nutrition Tips for Managing Diabetes :

Managing diabetes is about more than just monitoring your insulin levels. As with many things, your diet can play a significant part in maximizing your health.

While these tips won't magically cure things, they will certainly help.

1. Eat plenty of magnesium-rich foods

   Magnesium - in addition to playing a major part in the breakdown of carbohydrates - probably influences the release and activity of insulin (a hormone that helps to control blood sugar levels). People with type 2 diabetes are often found to have low levels of magnesium in their blood.

   Several studies (listed below) have recommended that those with diabetes eat plenty of magnesium-rich foods. Common sources include spinach, tofu, almonds, broccoli, lentils, pumpkin seeds and sunflower seeds.

2. Get plenty of omega-3 fatty acids

   Omega-3 fatty acids are perhaps most commonly taken (as supplements) in fish-oil capsule form; and have a number of benefits for everyone. A number of studies [ 1 ] have also found Omega-3 fatty acids to have a favourable effect on triglyceride levels in those with type 2 diabetes.

   Good sources of Omega-3 fatty acids include cold-water oily fish, fish-oil supplements, walnuts and freshly ground flaxseed.

3. Favor low GI foods

   As with the Omega-3 fatty acids above, a low GI diet (GI = Glycemic Index ) can help to lower triglyceride levels. Other general benefits of a low-GI diet include a lowering of LDL (bad) cholesterol levels whilst increasing HDL (good) cholesterol levels.

   Specific benefits of a low GI diet for diabetics include lower blood glucose levels (resulting in a lower HbA1c ) and potentially the need for less insulin.

   There is a wealth of information available on low GI eating; and common sources include beans, lentils and whole-grain breads.

4. Keep the carbs complex

   Complex carbohydrates (aka 'starches') take a bit more work to break down than their simple counterparts, and offer a range of health benefits for diabetics and others alike. Of particular note is an ability to lower LDL cholesterol levels [ 2 ].

   Examples of complex carb foods are wholegrain breads, pasta, rice, legumes, vegetables and fruit.

5. Get your fiber

   According to several recent studies [ 3 ], high-fibre diets and fibre supplementation both help to reduce LDL cholesterol levels; particularly in those with type 2 diabetes.

   Whilst wholegrain cereals are thought to provide the greatest benefit [ 4 ], other sources such as fruits and vegetables also have several health benefits.

Further reading - sites

Personally, I love wading through medical journals. If, however, you don't happen to share this strange obsession; the following sites are a little more down to Earth.

• American Diabetes Association (Nutrition & Recipes section)
  

  This site contains some excellent articles on many aspects of nutrition for those with diabetes; it also links to some great books on the subject.



• South Dakota Diabetes Prevention and Control (recipes page)
  

  Once you have an idea of which food sources are beneficial, you're probably looking for a few recipes. Head over to SD Diabetes.



• Harvard School of Public Health (Simple Steps to Preventing Diabetes)
  

  If you're fortunate enough to not have diabetes, this site has some great advice on keeping it that way.
