The fermentation process of yoghurt causes about 20% of milk sugar and protein to be hydrolyzed into small molecules (such as galactose and lactic acid, small peptide chains and amino acids, etc.), and the fat content in milk is generally 3% to 5%. After fermentation, the fatty acids in the milk can be doubled compared to the raw milk. These changes make the yogurt easier to digest and absorb, and the utilization of various nutrients is improved. Moreover, yogurt is fermented from pure milk, in addition to retaining all the nutrients of fresh milk, lactic acid bacteria in the fermentation process can also produce a variety of vitamins necessary for human nutrition, such as VB1, VB2, VB6, VB12 and so on. A study in 2011 found that foods containing probiotics such as yoghurt not only benefit digestive health, but also help reduce upper respiratory infections and reduce the incidence of influenza.

Rich in vitamin C can not only fight disease, but also relieve some severe cold symptoms and shorten the course of the disease.
However, it should be noted that spicy flavors have divergence, qi, and blood circulation. Eating too much makes it easy for the lungs to overgrow and consume qi and yin, leading to decreased immunity and colds, dry throat pain, and red eyes.

Complex species, at least more than 100 kinds, the main ingredients are water, fat, phospholipids, proteins, lactose, inorganic salts. Drinking milk often supplements the necessary vitamin D. Vitamin D is not only beneficial to bone health, preventing heart disease, but also helps improve immunity and effectively prevents colds and other symptoms caused by relatively large temperature difference.
For the middle-aged and the elderly, milk has a big advantage, that is, compared with many animal protein cholesterol, lower levels of cholesterol in milk, it is worth mentioning that some components of milk can also inhibit the liver manufacturing The amount of cholesterol makes milk also lower cholesterol.

It is one of the nutrients essential for normal brain activity. DHA can enter the brain through the blood brain barrier to increase and extend the synapse of brain nerve cells, thereby increasing the brain volume, enhancing memory, understanding, regular consumption, facilitating the regeneration of brain cells, improving memory, and preventing Alzheimer's disease. In addition, tuna can also improve the body's immune system and help combat cold attacks.
7. Oysters
Oysters are also known as oysters, which are the most abundant of all foods. Every 100g of oyster meat contains 87.1% of water and 71.2mg of zinc. Protein-rich zinc is a good zinc supplement food.

The ciliary muscle of the eye has a regulating effect on the lens of the eye, and the regulating function of the ciliary muscle depends on the facial muscle strength, and the enhancement of the facial muscle strength benefits from the chewing strength. Modern people's foods are increasingly softened, and there is little or no need for chewing when eating. This results in weakened facial muscles, reduced ciliary muscle regulation of the lens of the eye, and decreased visual acuity. Therefore, to improve vision, we must eat more hard food, and long-term insist on fully chewing food.
