Calcium deficiency is a very serious problem for the elderly over 70 years old. Many elderly people are afraid to go out because of mobility difficulties or fear of falling, cutting off contact with the outside world, resulting in poor mental state. Drink more milk and eat more dairy products and vegetables rich in calcium, such as broccoli, which can supplement calcium and help maintain bone density; Vitamin D helps to promote the absorption of calcium. In addition to dietary supplements, more sunlight can increase the level of vitamin D in the body. Need to be reminded that water shortage is also a common factor leading to falls of the elderly. Lack of water in the body may lead to dizziness, reduce the coordination and stability of the body, and greatly increase the risk of falling. Therefore, the elderly may wish to prepare a thermos cup to replenish water at any time when they are thirsty.

People over the age of 70 should also keep exercising, such as walking and playing Tai Chi, which will help relieve muscle atrophy and joint stiffness. You should also keep the habit of eating fish oil at ordinary times, which will help to slow down inflammation and increase the flexibility of joints.

The elderly are usually prone to lack of vitamin B 12, which can protect nerve cells, promote brain function and improve the oxygen carrying capacity of red blood cells. Fish oil and red meat are the best sources of natural vitamin B 12, and omega-3 and omega-6 fatty acids in marine food play an important role in promoting the health of eyes, brain and heart. At the same time, they can help the skin to form a barrier, prevent the skin from losing water and keep young.

People over 70 years old should take fish oil and DHA to protect their brains and memory. Eggs are also good food to protect the brain. Eating more fish, egg milk, tofu, soybeans or vegetables with more fiber will also contribute to the synthesis of acetylcholine in the body (the higher the content, the better the memory).
