Fried cakes are not recommended for patients with high blood sugar. Normally, a fasting blood glucose higher than 6.1 mmol per liter and a 2-hour postprandial blood glucose higher than 7.8 mmol per liter can be called high blood glucose. Deep-fried cakes contain certain fat and sugar, which can easily raise blood sugar, so patients with high blood sugar are not recommended to eat deep-fried cakes. Patients with high blood sugar should have a diet low in salt, fat and sugar, with lightness as the main focus. It is recommended to take coarse grains as the main food, eat more fresh vegetables and fruits, and avoid fried and high sugar foods, such as fried chicken and ice cream. It is recommended that patients with high blood glucose maintain a balanced nutrition in their life, control their blood glucose, exercise appropriately, and monitor their blood glucose regularly.
