Fried foods like youtiao and youbing are high in fat, which the digestive system can struggle to handle, easily leading to indigestion. They can also trigger or worsen gallbladder and pancreatic diseases. For older adults with good digestion, excessive fat intake can often lead to obesity. Furthermore, reused cooking oil often contains carcinogenic substances, and frequently eating fried foods can increase the risk of cancer.
Sweets are high in sugar. Consuming too much sugar can cause obesity, as excess sugar is converted into fat in the body. It can also lead to a deficiency of inorganic salts.
Animal organs, such as the liver, kidneys, and brain, are very high in cholesterol. If older adults consume them regularly, it can increase cholesterol levels in the blood, thereby easily triggering cardiovascular and cerebrovascular diseases like coronary heart disease, arteriosclerosis, and hypertension, or worsening existing conditions.
In addition, it is advisable to eat more vegetarian food and less meat. Food should be soft rather than hard, light rather than salty, and served warm rather than cold.
