Fasting, excessive abstinence: Diabetes patients' mistakes

Diabetes mellitus is a chronic conversion disorder, with excessive blood sugar increase caused by insulin deficiency. Nutrition plays a particularly important role in the treatment and maintenance of stable blood glucose. But not fasting, abstinence is good for diabetics.

1. The role of nutrition in diabetes

Diabetes mellitus is one of three diseases that go hand in hand with old age, along with cardiovascular disease and cancer. Diabetes mellitus causes a series of metabolism disorders in the body, first of all glucid metabolism disorders that increase blood glucose, leading to the appearance of glucose in the urine.

Glucid metabolic disorders entail disorders of lipid metabolism, protids, electrolytes, causing many dangerous complications for patients, especially can lead to coma and death if not treated in time.

Diabetes rates are increasing in the world and In Vietnam. According to 2002 data of the Endhrinrining Health Hub, the rate of diabetes in 4 major cities in our country (HO CHI MINH CITY, Hanoi, Hai Phong, Da Nang) is 4.1%.

Diabetes treatment is a long, austere process in which proper diet and nutrition play an important role.

Specifically, eating appropriately helps diabetics:

Maintain health, avoid minimized due to dietary diet

In fact, many patients with diabetes are afraid to eat, so abstaining a lot, not daring to eat many foods, both making the body undernourished and seriously affecting health but not high therapeutic effect. Here are the mistakes when fasting, excessive abstinence of diabetics:

Avoid excessive hypothlycemia

Patients do not know how to choose food, eat less rice but eat more noodles, potatoes … blood glucose levels still can't decrease. All are due to the lack of knowledge about the amount of nutrition in each food, which significantly affects the results of treatment of the disease.

Limit the use of drugs

If the patient has the right nutrition will help regulate blood glucose does not increase further, also limit the need to take additional medications or may not have to take the drug.

Limit complications

A glucose-restricted diet contributes to limiting dangerous complications because too high blood glucose levels are easy to cause urgent complications.

Nutrition helps control blood glucose

The role of nutrition in clinical diabetes is not enough to control blood glucose levels but still have to actively take medications and proper movement. But without proper nutrition, the drug alone is not enough to treat.

Therefore, it can be said that diet is one of the 3 factors that determine the effectiveness of diabetes treatment, along with the use of therapeutic drugs and reasonable physical activity.

2. Principles of proper nutrition for diabetics

2.1 Nutritional principles

Nutrition and eating for diabetics should ensure the following principles:

  • Enough protein, fat, powders, vitamins and minerals
  • Enough water.
  • Do not increase blood sugar after eating and lower blood sugar after far from meals.
  • Enough to maintain normal daily physical activity.
  • Maintain an ideal weight.
  • Does not increase dyslipidemia, blood pressure, kidney damage …
  • In accordance with the patient's eating habits.

2.2 Daily energy

Accordingly, depending on the patient who is fat or thin, the condition of blood sugar and blood lipids, the nature of labor and eating habits that perform:

Limit energy to obese people.

  • Males: 26 kcal/kg/day.
  • Females: 24 kcal/kg/day.

Energy is guaranteed to ordinary workers.

  • Bed treatment: 25 kcal/kg/day.
  • Light and moderate labor: 30 – 35 kcal/kg/day.
  • Heavy labor: 35 – 40 kcal/kg/day.

2.3 Energy composition ratio

In particular, the percentage of energy composition in feeds is as follows:

  • Glucid: 50 – 60% of total energy.
  • Protein : 15 – 20% of total energy.
  • Lipids: 20 – 30% with normal weight and blood lipids and less than 30 % with obese people.
  • Fatty acids: 10%.
  • Monounsaturating fatty acids: 10%.
  • Polyunsaturating fatty acids: 10%.
  • cholesterol: < 300 mg/ngày.
  • Fiber: 20 – 35 g/day.

2.4 Meal division

Diabetics need to divide their meals into several meals to combat excessive hypotensive after eating and hypotensive when hungry, especially patients taking hypoth glucose medications.

Diabetics should eat multiple meals a day

It is recommended to eat 5 – 6 meals a day with:

  • Breakfast: 20% of total energy per day.
  • Breakfast: 10% of total energy per day.
  • Lunch: 25% of total energy per day.
  • Afternoon Meal: 10% of total energy per day.
  • Dinner: 25% of total energy per day.
  • Dinner: 10% of total energy per day.

3. What foods do diabetics choose?

Foods that have equal amounts of glucid will increase different blood glucose levels after eating. The ability to increase blood glucose for users after eating is called the blood glucose index of that type of feed. This is the target for choosing food for diabetics.

To calculate the blood glucose index of a food, people take blood at hunger, after 15, 30, 60, 120 minutes after eating that food to compare with glucose, then calculate the change of blood glucose of food compared to glucose.

The specific calculation formula is as follows:

GITP = IAUCTP x 100/ IAUCG (wolever 1991)

Of which:

  • GI: blood glucose index.
  • Average IAUCTP plus UAUC (area increases below the curve of food).
  • IAUCG¬ average plus IAUC (increased area of glucose).
  • TP: food.
  • G: glucose.

People with diabetes should choose foods with a low blood glucose index:

  • Reduce glucid-supplied foods: rice, corn, noodles, potatoes; do not eat noodles.
  • Foods that provide protein: lean meat, fish, beans, unsym sugar-free milk, peanuts, sesame.
  • Foods that provide lipids: it is advisable to take oil, do not eat foods as high in cholesterol as organ coatings (320 – 5000mg%).
  • Foods that provide vitamins and minerals: vegetables, tubers, fresh fruits, limit eating too sweet fruits such as jackfruit, na, banana (glucid from 11.4 – 22.4%).
  • Less alcohol.

With food, drinks, confectionery … use of sweeteners, that is, those that create high sweetness but do not or provide very good energy as an alternative to other sweet foods with diabetics.

Some sweeteners are commonly used today such as Saccharin, Cyclamat, Aspartam …
