Prevent Type 2 Diabetes

  1. Make sure you get at least 30 minutes of exercise each day. For example walking around your neighborhood each day is a good idea. The key is to use large muscle groups. You could also try going to the gym a couple of times a week.
  2. Make sure you eat a balanced diet. Eat a little from each food group, and not too much of the bad stuff - like sugar, salt and fat.
  3. Watch the amount of sugar or carbohydrates you put into your body. Like instead of drinking a regular soda, drink water. Diet soda is often considered a good alternative, but the best is water. unfortunately, most foods labeled as "sugar free" or "low-carb" actually contain artificial sweeteners, sugar alcohols, and other additives that create a hormonal mess inside your body, actually stimulating your body to STORE more fat and stimulate cravings! And foods labeled "whole grain" only have to contain a small fraction of whole grains where the majority can still be refined starches and sugars that spike your blood sugar faster than a sugar-laden soda! A common mistake is believing that preventing diabetes means not eating any sugar. The truth of the matter is that you have to eat the right amount. People with diabetes have to take care that they don't eat too much or too little sugar. A good rule is based on the understanding that everything we eat turns to "a blood sugar;" therefore, choose foods that will take some time to convert. for example, sugar takes no time to convert to sugar, where protein takes more time. the key is balance in your diet.
  4. Drink plenty of water, because your body needs water. Water is better than any other drink if you need to keep hydrated. Water also fills you up so your desire to eat decreases.
  5. Maintaining a healthy weight is also very important. Of course eating well and exercising will help do that.

Eating For Good Health

The Australian Dietary Guidelines for Adults
Enjoy a wide variety of nutritious foods:
Eat plenty of vegetables, legumes and fruits Eat plenty of cereals (including breads, rice, pasta and noodles), preferably wholegrain Include lean meat, fish, poultry and/or alternatives Include milks, yoghurts, cheeses and/or alternatives. Reduced-fat varieties should be chosen, where possible Drink plenty of water. and take care to:
Limit saturated fat and moderate total fat intake Choose foods low in salt Limit your alcohol intake if you choose to drink Consume only moderate amounts of sugars and foods containing added sugars Speaking with a dietitian can help to improve eating patterns and set you on the right track for a healthier lifestyle. To find an accredited practicing dietitian in your area visit the Dietitians Association of Australia
Eating healthier is only one part of living a healthy lifestyle. Improving eating patterns in combination with physical activity and and maintaining a healthy weight will contribute towards a healthier lifestyle.

Food Hilights - for Diabetes suffers

Coffee
Coffee, especially decaf, helps reduce the risk of developing type 2 diabetes, suggests a 2006 study in the Archives of Internal Medicine. Postmenopausal women who drank 6 cups of coffee a day had a 22% lower risk of diabetes than women who did not drink coffee. Decaffeinated coffee drinkers had a 33% lower risk compared to non-coffee drinkers. A 2005 review in the Journal of the American Medical Association also found that drinking coffee on a regular basis helps reduce diabetes risk. The preventive effect was greatest for people who drank at least 4 cups of coffee a day.
Red Meat
Eating lots of red meat does more than boost unhealthy blood fats. It also increases heme iron intake, which can raise the risk of type 2 diabetes. In a 20-year study of 85,000 women, the risk of diabetes increased along with heme iron intake. Women with the highest intakes had a 28% increased risk compared to those with the lowest intakes. Replacing red meat with chicken may help improve kidney function in patients with type 2 diabetes, suggests a small study in the American Journal of Clinical Nutrition.
Vitamin E
Vitamin E supplements do not help prevent cancer or heart disease and may increase the risk of heart failure for patients with diabetes, according to a 2005 study in the Journal of the American Medical Association.
Folic Acid and B Vitamins
Vitamin B supplements do not help prevent heart disease, according to several 2006 studies in the New England Journal of Medicine. In the Heart Outcomes Prevention Evaluation (HOPE) trial, researchers assigned over 5,500 patients with diabetes or vascular disease to receive either a folic acid - vitamin B6 - vitamin B12 combination or placebo for 5 years. The vitamins did not reduce the risk of heart disease or heart attack.

Exercise and diet for preventing type 2 diabetes mellitus

Type 2 diabetes is mainly characterised by a reduced ability of the hormone insulin to stimulate glucose uptake in body fat and muscles (insulin resistance) combined with insufficient insulin secretion that leads to increased blood glucose levels. It has been shown that weight reduction and an increase in daily energy expenditure decreases insulin resistance. There are some factors that are associated with an increased risk of type 2 diabetes: these are obesity, previous gestational diabetes, hypertension, family history of type 2 diabetes, dyslipidaemia and some ethnical groups are more at risk. Persons with "prediabetes" are also at high risk: they have abnormal blood glucose levels but not in the range of diabetes. Prediabetes often precedes the development of type 2 diabetes. We searched for trials that intended to prevent the development diabetes type 2 in the above mentioned at risk groups. We assessed the effects of increased physical activity alone or in combination with dietary interventions on diabetes incidence and other outcomes.
We included eight trials with 2241 participants randomised to exercise and diet intervention and 2509 participants to standard recommendation. Furthermore, 178 participants were randomised to an exercise only intervention and 167 participants to a diet only intervention. The duration of the interventions in the trials ranged from one year to six years. Interventions varied between studies but mainly consisted of caloric restriction if the person was overweight, low fat content (especially saturated fat), high carbohydrate content and the increase of fibre intake. Physical activity varied but on average at least 150 minutes each week of brisk walking or other activities such as cycling or jogging were recommended. Interventions were mainly delivered by frequent individual counselling by a physiotherapist, an exercise physiologist and a dietitian. Incidence of diabetes was reduced by 37% (relative risk reduction) with exercise and diet. This had favourable effects on body weight, waist circumference and blood pressure. More evidence is required on effects of exercise alone in the prevention of type 2 diabetes. No study reported relevant data on diabetes and cardiovascular related morbidity, all-cause mortality and quality of life.

Dietary advice during pregnancy to prevent gestational diabetes

Diabetes mellitus is associated with abnormal glucose metabolism, with raised blood sugar and sugar in the urine. When this arises in pregnancy and disappears after birth, it is called 'gestational diabetes mellitus' or GDM. Between 1% and 14% of women develop GDM in pregnancy, with some women more at risk than others, and the severity can vary too. Risk factors for gestational glucose intolerance include being of a particular ethnicity, previous GDM, family history of type II diabetes mellitus and being older. Often there are no symptoms, or the symptoms can include tiredness, excessive thirst, passing a lot of urine and blurred vision. GDM can also cause significant problems such as a very large baby, an increased risk of the shoulder getting stuck during birth and injury to the mother during birth. There is also an increased chance of having an induced birth and caesarean birth. Babies can also often be born too early and have less chance of surviving, have problems with breathing and jaundice. In addition, there can be long-term effects such as increasing the risk of diabetes for mother and child later in life. Diet may play a significant part in the control of diabetes, with wholegrain carbohydrates and low glycaemic index diets (LGI) being helpful. LGI diets aim to slow down the digestion of food, allowing the body to better adjust to the load of sugar coming in after a meal. It is possible, therefore, that dietary advice in pregnancy may reduce the number of women who get GDM and its effects.
The review of dietary advice in pregnancy to reduce GDM identified three trials involving 107 women, undertaken in Western countries. One trial involving 25 women looked at high-fibre diets compared with normal pregnancy diets. Two trials, involving 82 women, looked at LGI diet compared with high glycaemic index diet, with one of these trials also including an exercise component. The outcomes relevant to the review in the trial on high-fibre diets were inconclusive. The results on the low glycaemic index diet suggested that this may be beneficial to the mother and child. However, the evidence was not strong enough to be confident of these effects.
