The brain is the most important organ in the body: It ensures the functioning of all systems, and this is why it is essential that the brain functions optimally with a healthy diet.

Some foods have negative effects on the brain, affecting memory and mood and increasing the risk of dementia. Fortunately, you can help reduce your risk of disease by eliminating certain foods from your diet.

1. Sugary drinks: High consumption of sugary drinks can increase the risk of dementia. High fructose corn syrup (HFCS) can be particularly harmful, causing brain inflammation and impairing memory and learning. Further studies in humans are needed.

2. Refined carbohydrates: A high consumption of refined carbohydrates can impair memory and intelligence, as well as increase the risk of dementia. These include sugars and highly processed grains such as white flour.

3. Foods with trans fats (fat found naturally in meat or dairy fat): Trans fats may impair memory and increase the chances of Alzheimer's, but the evidence is mixed. Cutting out trans fats entirely and increasing unsaturated fats in your diet can be a good strategy.

4. Processed foods: Processed foods contribute to excess fat around the organs. Western-style diets can increase brain inflammation and damage memory and the brain.

5. Aspartame: Aspartame is an artificial sweetener found in many soft drinks and sugar-free products. It has been linked to cognitive behavioral problems, although it is generally considered a safe product.

6. Alcohol: Drinking alcohol in moderation can have positive health effects, however excessive consumption can impair alertness, affect behavior and disrupt sleep.

7. Fish High in Mercury: Mercury is a neurotoxic element that can be especially harmful to developing fetuses and young children. Therefore it is good to limit the consumption of fish that are rich in mercury.
