Food can play a cruel joke with our brain: some popular foods, including those considered useful, inhibit mental activity, and with constant use, they impair cognitive abilities and even destroy brain cells.
Doctors recommend limiting the use of such foods in order to minimize their negative impact and maintain a clear mind, according to webMD. Study this list carefully.
Be careful with tuna. This fish is considered healthy, but eating it too often is strictly prohibited due to its high mercury content. This toxic substance builds up in the body and breaks it down. Moreover, scientists have shown that mercury causes drowsiness, apathy, impairs memory and leads to a loss of self-control.
2. French fries and other fried foods
People who eat a lot of fried, especially deep-fried foods tend to perform worse on tests that assess their thinking skills. The danger is represented by a large amount of fats, which cause inflammation in the body. As a result of damage to the blood vessels that supply the brain with blood, brain cells are destroyed.
3. Sweet drinks
Almost all sugary drinks have a similar effect. Yes, at first they make you more cheerful, but later you will have to pay for this energy with the neurons of the brain, which are responsible for your cognitive abilities. Studies have shown that people who drink a lot of sodas, sugary teas, and other sugary drinks have frequent memory problems. The fructose found in these drinks can even lead to shrinkage of certain areas of the brain.
4. Margarine, mayonnaise and convenience foods
These foods are high in trans fats, which are extremely harmful to the heart and blood vessels. Studies have shown that they can also harm the brain, as they badly affect the cell membrane, making it more rigid. A study in the journal Neurology found that older adults who had the highest blood levels of elaidic acid (a common type of trans fat) were more likely to develop dementia.
5. White bread and white rice
Refined carbohydrates, even those that are unsweetened in taste, can raise blood sugar levels. And this entails a deterioration in cognitive abilities. An excess of refined carbohydrates may increase the risk of Alzheimer’s disease, especially in people who are genetically predisposed, according to research. Choose whole grain breads, brown rice, and whole wheat pasta – these carbs won’t harm your brain.
