3. Sugar

Refined Sugars

Your brain requires the proper amount of sugar, or glucose, as a source of energy for performing critical functions. Nonetheless, too much of a good thing can be damaging to brain cells. Sugar is found naturally in fruits and vegetables. However, it is the added sugar contained in many products on grocery store shelves that causes you to consume excess sugar. A study in Neuroscience shows that excess sugar affects the brain chemicals that play a part in memory formation and learning. Check food labels when shopping and avoid items with sugar or corn syrup prominent in the ingredients.

2. Sugary Drinks


Sodas, fruit juices, and sports drinks can all be high in added sugar. Fruit juices may seem like a healthy choice. After all, they come from fruit. However, these products are often high in sugar and low in critical dietary fiber. Sports drinks tend to contain excessive amounts of sugar in addition to water and electrolytes. Sodas are notoriously high in sugar or sugar substitutes and devoid of nutrients. Treat your brain right and stick to plain or fruit-infused water. Consume whole fruits instead of fruit juices. Whole fruit is high in fiber as well as vitamins, minerals, and water.

1. Trans Fats

Trans Fats

Healthy, monounsaturated fats are beneficial for your brain, heart, and cholesterol levels. However, the trans fats found in processed foods, shortening, hydrogenated oils, fried foods, and stick margarine have adverse effects on your heart and your brain. A study review in the Neurobiology of Aging suggests there is a link between dietary saturated and trans fats and the risk of mental decline. A diet high in saturated or trans fats may increase the incidence of dementia, Alzheimer’s disease, mild cognitive impairment, and cognitive decline. Instead, stick to the healthy fats found in avocado, olive oil, and nuts.
