2. Fast Food
It’s no secret, that foods that are high in fat cause fatigue, making your brain feel sluggish. While chips, ice cream, and cookies are all bad fat-offenders, some fast food options are a powerhouse of ingredients bad for your brain, including trans fat, saturated fat, sodium, sugar, fillers and artificial flavorings.
According to research, the average American chows down on 79 pounds of added sweeteners every year. That’s more than one fifth of a 1,800-calories-a-day diet—along with 63 pounds of fat – all wreaking havoc on brain chemistry in a matter of weeks, Women’s Health says.
3. Ice Cream
One bedtime bowl of vanilla ice cream can add up to 10 grams of artery-clogging saturated fat and nearly 28 grams of refined sugar. Multiple studies have shown that saturated fat and sugar-rich diets can diminish cognitive skills and memory recall.
