Here Are the Ten Worst Foods for Your Brain

The brain functions as a kind of ‘control room’ of our body, so it is necessary to take care of it to ensure the excellent functioning of everything else. And, as with any organ, some foods are better for it than others. Here are some examples of exercising caution.


It should be no surprise that the top spot is occupied by alcohol. But, in addition to its adverse effects on the cardiovascular level and the rest of the body, several studies have found that excessive drinking is related to a higher incidence of dementia and an earlier onset of symptoms.

Red meat

Red meat is an excellent contribution of iron, a necessary element for proper health. However, some studies have found that excess iron contributes to developing diseases such as Alzheimer’s, so it is advisable to moderate its consumption.

Very sugary drinks and foods

The intake of excessive sugar levels causes cardiovascular problems (including cerebrovascular issues) and, in addition, is related to decreases in memory and learning ability.


Fried foods can significantly increase levels of ‘bad’ cholesterol in the blood, increasing the chances of developing amyloid beta proteins (indicators of dementia and Alzheimer’s) in the brain.

Simple carbohydrates

By simple carbohydrates, we mean all those foods made with refined cereals. Some research has found that excessive consumption has deleterious effects on memory; in general, comprehensive alternatives are considered much healthier.

Food rich in trans saturated fats

Foods such as junk food or frozen pizza are high in trans-saturated fats, which markedly increase the risk of stroke.

Excess salt

Diets excessively high in sodium are linked to an increased risk of dementia and problems such as hypertension, which can trigger strokes. However, in its proper measure, sodium is necessary for the appropriate functioning of the body.

Processed meats

Processed meats are often rich in salt, sugars, and chemicals such as preservatives or dyes, increasing the odds of degenerative disorders.

Saturated fats.

It seems that saturated fats, present mainly in dairy and terrestrial animals, can lead to a decrease in cognitive performance.

Fish with high levels of methylmercury.

This food may surprise us since we are used to hearing about the beneficial properties of fish. However, some species, the largest, longest-lived, and predatory, may contain high levels of methylmercury that, by bioaccumulation, can be neurotoxic. Therefore, it is better to moderate the consumption of these species and usually opt for others lower in this heavy metal.
