Four foods that are damaging your brain

IF YOU believe the saying that you are what you eat as gospel, then you might want to reconsider before popping the following foods in your mouth.

While some may be tasty, research has shown that they're could actually be damaging your brain.

Foods with a high glycemic index, such as white bread, have been found to have a negative impact on your brain, and even contribute to depression.

1/ WHITE RICE & BREAD

Sorry to be the bearer of bad news, but foods with a high glycemic index (ie refined carbohydrates such as white rice and bread or even potatoes) have been found to have a negative impact on your brain, and even contribute to depression.

According to a study published in 2015 in the American Journal of Clinical Nutrition, post-menopausal women who eat foods with a high glycemic index have increased odds of suffering from new-onset depression.

Meanwhile those with a higher consumption of lactose, fiber, non-juice fruit and vegetables were found to have lower odds of depression.

A study in 2011 published in the Neurology journal found that eating too much trans fat (such as that found in margarine) reduced cognitive function and total cerebral brain volume.

2/ TRANS FAT

It's time to step away from the microwave popcorn, margarines and other processed foods that are high in trans fat, such as some frozen pizzas and pre-made icing.

A study in 2011 published in the Neurology journal found that eating too much trans fat reduced cognitive function and total cerebral brain volume.

The findings were backed up by another study in 2014, which found a link between high trans fat consumption and memory loss among working-age men.

A recent study of about 1000 healthy men, found that those who consumed the most trans fats performed noticeably worse a word memory test, regardless of other considerations like age, education, ethnicity and depression.

If that's not bad enough, trans fat may also accelerate the skin's aging process by making the skin more vulnerable to ultraviolet radiation.

Foods laden in saturated fat, such as fried chicken, have been shown to disrupt the blood barrier which is a complicated system used by the body to get nutrients to the brain.

3/ FRIED FOODS

Put down the doughnuts, fried chicken, hot chips and anything else that's laden in saturated fat. Unfortunately these fats have been shown to disrupt the blood barrier which is a complicated system used by the body to get nutrients to the brain.

Any disruption can prevent nutrients from getting to the brain and also allow harmful substances to get through, potentially damaging the brain.

Fried foods are also known to increase blood cholesterol levels.

A study published in the Journal of the American Medical Association in 2014 revealed that people with who have high levels of bad cholesterol (LDL) and low levels of good cholesterol (HDL) were more likely to have a build-up of beta-amyloid proteins in their brains, which are harbingers of dementia and Alzheimer's Disease.

4/ SUGAR

Oh so seductive, but sugar has become almost a swear word in some circles because of its negative impact on your health.

But it's not just soft drinks or sweet cakes that are a risk factor, 'healthy' options like fruit juice can also be just as bad for you due to the high sugar content.

A study published in the journal Neuroscience in 2015 found that mice subjected to high-sugar, high-fat diets suffered from significant cognitive decline.

Those on the high-sugar diet suffered the greatest declines, with their long- and short-term memory and cognitive flexibility all being impacted.
