Normal cholesterol levels are a guarantee of mental agility because it affects cardiovascular efficiency. LDL cholesterol can be deposited... In blood vessels, hindering blood circulation to the brain, so that the brain does not get enough nutrients, leading to memory loss; therefore, usually eat less food containing saturated fatty acids, such as animal oil, coconut oil, fatty meat, fatty sausage and so on.
Fitness and brain method
More brain can indeed keep the mind strong, aerobic exercise is also beneficial to improve memory, the French scientific mound called this "brain jogging". Aerobic exercise speeds up blood flow throughout the body, and more blood is delivered to the brain, bringing in more oxygen and glucose, which can enhance brain function.
Sleep and rest method
American Harvard Medical School expert research results show that: sleep can improve memory. Elderly people can strengthen the brain through learning, if coupled with a good night's sleep, it can make the memory of the first day to be consolidated, this is because sleep allows the brain to have time to encode for the memory, and fix the information, thus improving memory.
Stress memory
As far as short-term memory is concerned, appropriate stress promotes memory because it is a survival mechanism for the human body; studies of the effects of memory stress have found that neurons in the brains of older people with memory loss need to maintain relatively high levels of stress hormones. If older people consciously apply - a little pressure for themselves, suggesting that they must remember something, so that the secretion of stress hormones increased, it will enhance memory.
Hands **** with
In order to enhance memory, used to use the right hand people, to the middle and old age may wish to change to use the left hand to write or do life chores, so that the other half of the brain's conduction beams to complete it is not familiar with the work, so that the enhancement of memory is also very effective.
Appropriate iron supplementation
Iron is an important component of hemoglobin, which is vital for memory. If older people are anemic, their memory will decline significantly. Therefore, older people should check whether they have iron deficiency anemia through regular laboratory tests.
Since iron is not easily absorbed, it is best for the elderly to opt for dietary supplements and pay attention to eating more iron-rich foods such as jujubes and liver.
Two cups of blueberry juice
Elderly people who drink two small cups of blueberry juice every day will have significantly improved memory. This is because blueberries are rich in anthocyanins, which are powerful antioxidants that can protect the body from damage caused by harmful free radicals, enhance the brain's signaling ability, and strengthen the elasticity of the cerebral blood vessels, which in turn can slow down neurodegeneration.
Drink some red wine every day
Red wine helps maintain memory. Complex red wine contains resveratrol, which can help ward off Alzheimer's, lower cholesterol levels, slow down memory loss and improve blood circulation to the brain. So drinking 50 milliliters of red wine a day for the elderly is great for improving memory.
Caring for children
Professor Craig Kingsley of the University of Richmond in the US says women who have just become mothers secrete large amounts of oestrogen to boost their sensitivity and concentration. For the elderly, caring for children on a daily basis also exercises brain flexibility.
Learn a foreign language
Research at the University of Toronto in Canada has shown that seniors with a command of two languages have a four-year delay in developing Alzheimer's disease compared with others. Learning a foreign language increases the density of gray matter in the hippocampal region of the brain, enhancing a person's memory and concentration.
