10 Foods to Prevent Dementia and Stay Sharp in Old Age.

Alzheimer's disease has a slow and insidious onset, making it difficult for patients and their families to pinpoint when it began. Without proper health care, symptoms of Alzheimer's can easily appear, and over time, they can affect daily life. So, what can be done? Here, we will introduce 10 foods that help prevent Alzheimer's disease. Come and see what they are.

1. Soybeans

Soybeans are known as "China's milk." They are rich in oils, phospholipids, and more than 20 kinds of vitamins and trace elements. Specifically, the lecithin in soybeans, once it enters the human brain, can release acetylcholine. Acetylcholine promotes information transmission between nerve cells, thereby improving the symptoms of Alzheimer's patients. Moreover, soybean fat is also highly nutritious, containing many unsaturated fatty acids that are easily digested and absorbed by the body. Soybean fat can also inhibit the absorption of cholesterol, making it an ideal nutritional supplement for patients with arteriosclerosis.

In addition, the dietary fiber in soybean residue plays a crucial role in promoting good digestion and the excretion of solid waste. Adequate fiber supplementation can increase the volume and soften food in the intestines, promote intestinal peristalsis, and thus speed up bowel movements, preventing constipation and reducing the risk of colon cancer. At the same time, dietary fiber has significant effects on lowering plasma cholesterol, regulating gastrointestinal function, and insulin levels.

2. Millet

Millet is highly nutritious, rich in protein, fat, and vitamins. It is not only used for food but also in medicine for its effects of clearing heat, quenching thirst, nourishing yin, tonifying the spleen and kidneys, regulating the stomach and intestines, promoting urination, and treating diarrhea. It can also be used to make wine. Furthermore, millet is rich in Vitamin B1, Vitamin B2, and large amounts of tryptophan and glutamic acid. These vitamins and amino acids are beneficial for brain health. Therefore, the elderly can eat more millet regularly. In addition to protein, millet also contains complex B vitamins, calcium, potassium, fiber, and more. Because millet is alkaline, it doesn't require much salt or can even be cooked without salt.

3. Spinach

Spinach is rich in carotene, vitamin C, calcium, phosphorus, and a certain amount of iron, vitamin E, rutin, coenzyme Q10, and other beneficial components, providing the body with a variety of nutrients. The iron it contains has a good auxiliary therapeutic effect on iron-deficiency anemia. The abundant nutrients like vitamins A, C, B1, and B2 also provide energy for brain cell metabolism. Spinach also contains a large number of antioxidants that can eliminate some harmful substances in the body. Therefore, eating spinach regularly can help alleviate symptoms of memory decline in the elderly.

4. Daylily

In traditional Chinese medicine, daylily is considered sweet and cool in nature, with effects of stopping bleeding, reducing inflammation, clearing heat, promoting urination, aiding digestion, improving eyesight, and calming the spirit. It is effective for conditions like hemoptysis, bloody stools, urinary retention, insomnia, and insufficient lactation, and can be used as a restorative supplement after illness or childbirth. Modern medical research has found that daylily contains nutrients such as vitamins A, B1, C, D, plant fats, sixteen amino acids, and various trace elements. Therefore, daylily is considered a brain-healthy vegetable. However, it should be noted that when eating fresh daylilies, they should first be blanched in boiling water, then soaked in clear water for 2 hours. Also, one should not eat too much at a time, as it can easily lead to poisoning.

5. Walnuts

Walnut kernels are rich in nutrients. Every 100 grams contains 15-20 grams of protein, a relatively high amount of fat, and 10 grams of carbohydrates. They also contain various trace elements and minerals essential for the human body, such as calcium, phosphorus, and iron, as well as multiple vitamins like carotene and riboflavin. They are beneficial to the human body and are one of the most popular nut foods among the public. Research has found that walnuts are rich in unsaturated fatty acids—linoleic acid—which, after being absorbed by the body, is transformed into a component of brain cells.

Although walnuts are good, it should be noted that they cannot be eaten with pheasant or duck meat. Walnuts contain a relatively high amount of fat, and eating too much can affect digestion, so it is not advisable to eat too many at once. Furthermore, to preserve nutrients, the thin brown skin on the surface of the walnut kernel should not be removed when eating. Eating too many can cause diarrhea. Patients with phlegm-fire asthma and cough, yin deficiency with excessive fire, or loose stools and diarrhea should avoid them.
