Lin Xinjie arranges and edits spices and herbs full of special smells, which are often used to add flavor to dishes. Their natural characteristics of low calorie and low fat enable people to enjoy delicious diet dishes with only a small amount of herbs. In fact, in addition to losing weight, some preliminary studies in recent years have found that some spices and herbs are also good for the brain, which can help prevent dementia, improve memory, reduce anxiety and even eliminate tumors. Curcuma longa —— Prevention of Alzheimer's Harmo's disease There is a kind of white blood cell called "macrophage" in human body, which can destroy foreign particles, but the macrophages of some patients with Alzheimer's disease can't play a role. When the function of macrophages is not good, the plaque of amyloid beta protein, which is considered as the killer of Alzheimer's disease, cannot be removed. Some compounds in turmeric can activate macrophages and help to eliminate amyloid β protein spots in the brains of patients with early Alzheimer's disease. At present, it is uncertain how much curry is needed to achieve the same effect as in the experiment. Sage-improving brain function Sage is "Sage" in English, and this word also has a wise meaning, which just supplements the health care function of Sage. In two small studies, Salvia Miltiorrhiza extract capsules can promote the memory test performance of subjects for several hours. Another animal experiment pointed out that sage essential oil or extract can block an enzyme and prevent it from reducing neurotransmitters related to brain functions such as learning, memory and attention. However, sage can raise blood pressure, and patients with hypertension should avoid taking it. Thyme, Brazil —— Strengthening neurons A recent study in Brazil found that there is a flavonoid called apigenin in these spices, which can strengthen the connection between neurons and even promote the specialization of stem cells into neurons. Although this research is only conducted in the laboratory at present, and it has not been conducted in a living human body, the researchers hypothesized that a diet rich in apigenin may also affect the formation and connection of brain cells, which can theoretically help prevent depression, Alzheimer's disease and Parkinson's disease. Linus from Oregon State University? Giana Angelo, research assistant of Pauling Micronutrient Research Information Center, explained that the chemical structure of apigenin is similar to estrogen, which has long been considered to affect the development of nerve cells. Angelo said that in this study, apigenin can imitate estrogen and cause the same type of cell changes. Chamomile-relieving anxiety As a popular night tea, chamomile tea is a kind of food to relieve stress, which has been used by many people and proved to be effective. Although there is only laboratory research at present, Angelo explained that the substances contained in chamomile may be combined with receiving some brain chemicals to reduce anxiety. In one experiment, a group of people with generalized anxiety disorder were randomly given chamomile extract or placebo. After eight weeks, more people who ate chamomile extract reported less anxiety than those who ate placebo. In 2007, a study put forward the hypothesis that garlic can cure brain tumors, which caused a sensation at that time. Studies have shown that some active compounds in garlic can kill cancer cells in Petri dishes. Angelo pointed out that at present, scholars can't directly draw a conclusion from the research on whether eating garlic can have the same effect on the brain, especially the dose of compounds used by researchers is much higher than that obtained by eating garlic, but this research is still a complete beginning. Although spices have many benefits, excessive consumption may also be harmful to the body, so it is still necessary to take personal health as the standard, and moderate consumption will not harm the body in turn!
