10 foods that can undermine your intelligence

When it comes to nutrition, it is important to note that there are several types of foods. Some are allies in weight loss, others stimulate cognitive function and improve memory, and some are known to have a devastating effect on brain function. Therefore, they should be avoided or consumed sparingly so that their negative impact is limited.

Here are some foods that can impair intelligence:

1 ? Sugar

Sugary products are bad not only for fitness but also for brain functions. In the long run, sugar consumption can cause many neurological problems and interfere with memory and ability to learn.


2 ? Alcohol

In addition to damaging the liver, alcohol can also cause mental confusion, acting as a cloud that affects the ability to think clearly and also memory. This happens due to the intake of large amounts of alcohol. Symptoms are reversible if drinking is stopped or limited to social occasions. Two drinks a week don't hurt.

3? Fast food

These foods are high in fat and have no benefit to either body or health. They affect the production of dopamine, a chemical that promotes the feeling of happiness and well-being, as well as aiding cognitive function and learning ability, attention, motivation and memory.

4? Fried food

Almost all processed foods contain chemicals, colorings, additives, artificial flavors, preservatives that can affect behavior and cognitive functioning, as well as causing hyperactivity in both children and adults. Fried foods slowly destroy nerve cells located in the brain.


5? salt

Very salty foods affect blood pressure and are very bad for the heart. And they can also affect cognitive function and impair the ability to think. Some research has shown that consuming salty foods and nicotine have the same effect as drugs in the body.

6? Grains

With the exception of 100% whole grains (which are high in fiber and prevent arterial aging), all other grains have an impact on brain function and may cause memory loss and mental confusion. So try switching from regular carbohydrates to wholegrain.

7? Processed Proteins

Meat is the richest source of protein, but excessively processed meat, such as sausages, salami, and others, has a harmful effect on the body. Prefer natural sources of protein such as fish, especially tuna and salmon, dairy, nuts and seeds.


8? Trans fat

Trans fats are responsible for a number of health problems, damaging cholesterol, the heart, and increasing the chances of obesity. They are also bad for the brain and can result in brain shrinkage, something similar to Alzheimer's disease. In addition, they increase the risk of having a stroke.

9? Artificial sweeteners

People who want to lose weight tend to replace sugar with sweetener because they contain less calories. But on the other hand, if they are used for an extended period of time, they can interfere with cognitive ability.

10? Nicotine

Although not a food, nicotine can be considered as one of the most harmful products to health. In addition to causing premature skin aging, bad breath and increased chances of developing lung cancer, it affects the production and function of neurotransmitters by compressing blood vessels, which play a key role in brain function.
