There are foods that are real “usurpers” of our energy and end up harming brain activity. Symptoms such as low mood, fatigue, stress, emotional exhaustion, constant forgetfulness, and even lack of concentration can be caused by poor food choices.

Foods That Harm Brain Health

high in sugar

According to Professor Pedro Calabrez, from the Youtube channel Neuro Vox, “any type of sugar that causes blood sugar to spike is extremely harmful to the body in general and to your brain in particular”.

According to the professor, this applies to all types of sugars, including those in fruit. The ideal is to eat the fruit in naturebecause in this way the body receives fibers that help to avoid the absorption of sugar, avoiding glycemic peaks.

Refined sugar and the sugar found in wheat flour, starch and flour, which turn into blood sugar, can cause a chemical process called glycation, which means changes in the levels of sugar released into the blood. This fact can lead to the emergence of inflammatory processes, problems with arthritis and cardiovascular diseases.

trans fat

Everyone knows that excessive consumption of fatty foods leads to obesity, but many people ignore the fact that foods containing trans fats (fatty triglycerides that occur naturally in foods of natural origin or are products in the food industry to enhance and highlight the flavor of the food product) are extremely harmful to the body.

Trans fats are easily found in foods such as: ice cream, packaged snacks, chocolates, cookies, instant pasta, vegetable creams, etc.

The consumption of these foods increases the risk of many diseases, in addition to causing different damage to health, and can increase the levels of “bad” cholesterol (LDL) and the risk of stroke, atherosclerosis and myocardial infarction and other cardiovascular diseases.

However, these are the most related long-term risks. When you think of the short term, eating foods high in fat slows down the digestive process. This causes more energy to be directed to the digestive process, which decreases the transport of oxygen to other areas of our body, such as the brain. It is for this reason that we feel more tired and lacking in energy soon after eating such foods.


From a nutritional point of view, the best type of animal protein is fish protein. However, due to the great contamination of rivers and oceans, this food had to enter the list of foods not recommended for regular daily consumption. This is because they can contain a high concentration of methylmercury, which is highly toxic to the body. The fish that have the highest rate of contamination are sharks, swordfish, needlefish, pirarucu trairão, piranha.

The options with the lowest mercury concentrations are chaputas, anchovies, catfish, shellfish, lobsters, oysters, salmon, sardines, tilapia, squid, and cod.

According to health professionals, the consumption of fish should not exceed once a week, being consumed a maximum of twice a month. Unless you are sure that the origin of the animal is of quality.
