General principles of nutritional therapy
Patients with diabetes and prediabetes need to receive individualized medical nutrition treatment according to the treatment objectives.
It is best done under the guidance of a nutritionist who is familiar with diabetes treatment.
Control the intake of total energy and distribute various nutrients reasonably and evenly.
The goal of nutritional therapy
■ Achieve and maintain the ideal blood sugar level.
■ Reduce the risk factors of cardiovascular diseases, including controlling dyslipidemia and hypertension.
■ Provide a balanced and nutritious diet.
■ Reduce islet β cell load.
■ Maintain a reasonable weight: The goal of overweight/obese patients is to lose weight successfully within 3-6 months.
5%- 10% lighter. Patients with emaciation should recover and maintain their ideal weight for a long time through a balanced nutrition plan.
fat
■ The energy provided by dietary fat does not exceed 30% of the total dietary energy.
■ The intake of saturated fatty acids and trans fatty acids should not exceed 10% of the total dietary energy.
Monounsaturated fatty acids are a good source of dietary fat and should reach the energy supply ratio of total fat intake.
10%-20%。 The intake of polyunsaturated fatty acids can be appropriately increased, but it cannot exceed the total energy intake.
10%
■ Cholesterol intake in food
carbohydrate
■ The energy provided by carbohydrates in the diet should account for 50%-60% of the total energy.
■ Low glycemic index foods are beneficial to blood sugar control.
■ The blood sugar elevation caused by sucrose is similar to that caused by the same amount of starch, and does not exceed 10% of the total energy.
■ It is safe for diabetic patients to take sugar alcohol and non-nutritive sweeteners in moderation.
■ Eat three meals regularly every day and distribute carbohydrates in a balanced way.
protein
■ For diabetic individuals with normal renal function, the recommended intake of protein is 10%- 15% of the energy supply ratio.
■ protein intake of patients with obvious proteinuria should be limited to 0.8g/kg/d, which should be realized when GFR decreases.
The recommended dosage of low protein diet in protein is 0.6g/kg/d, supplemented with compound α -keto acid preparation.
■ Intake of protein will not increase blood sugar, but it can increase insulin secretion.
Drink wine/alcohol
■ Drinking alcohol is not recommended for diabetics. When drinking, the calories contained in drinking should be included in the total energy quota.
Wainei
■ Do not exceed the standard dose of 1-2 per day.
(A standard quantity is: beer 350ml, red wine 150ml or low-alcohol liquor 45ml, and each bottle contains about 15g of alcohol).
■ Alcohol may promote hypoglycemia in patients treated with sulfonylureas or insulin.
salt
■ Salt intake should be limited to 6g per day, and patients with hypertension should strictly limit their intake.
