Avoid overfull, intake of food containing too much sugar, eat more fruits and vegetables. 2, should not be too hungry: too hungry will lead to hypoglycemia, serious will cause hunger ketosis, so hunger can be moderately small meals. 3, not greedy: usually eat to not drink alcohol is appropriate, should also politely decline to drink when going to a banquet. 4, do not eat more salt: foreign experts found that the plasma glucose concentration of those who eat salt-containing food is higher than those who eat salt-free food. So eating less salt may be an adjuvant treatment for diabetes. Avoid eating: white sugar, red pond, glucose and sugar sweets, such as sugar, pastry, jam, honey, preserves, ice cream, etc. Less to eat: potatoes, yams, taro, lotus root, onions, carrots, lard, suet, cream, butter, peanuts, walnuts, sunflower seeds, egg yolk, liver, kidney and brain. Desirable food: coarse grains such as buckwheat, oatmeal, cornmeal, soybeans and soy products, vegetables. Diabetes scientific and reasonable diet is the basis for controlling diabetes, but many diabetic patients have the following misconceptions about diet therapy: excessive diet or full vegetarian diet or even the “Purgatory” method of treatment of diabetes at the beginning due to reduced caloric intake, so that blood sugar, urine sugar temporarily decreased, but then due to insufficient intake of nutrients, the body can only be used for energy activities by However, due to insufficient nutrient intake, the energy for human activities can only be supplied by the decomposition of body fat, the product of which is ketone bodies, thus causing ketoacidosis, which can be life-threatening in serious cases. This method is not advisable. Restriction of water Some patients have symptoms of polyhydramnios and polyuria at the beginning of the disease, so they restrict water intake, which is inappropriate.
