Foods that Kill your Intelligence

Scientists say our brains need sugar every day to function. “Brain cells require two times the energy needed by all the other cells in the body — roughly 10 per cent of our total daily energy requirements. This energy is derived from glucose (blood sugar), the gasoline of our brains,” 

Research indicates that a diet high in added sugar reduces the production of a brain chemical known as Brain-Derived Neurotrophic Factor. Without BDNF, they note, our brains can’t form new memories and we can’t learn (or remember) much of anything. Levels of BDNF are particularly low in people with an impaired glucose metabolism — diabetics and pre-diabetics —and as the amount of BDNF decreases, sugar metabolism worsens.

What are these foods? Here are some of them:

Sugary products

The list is endless, and they include biscuits, canned and bottled drinks, canned fruits in syrups, sweetened ‘fruit’ juices, dissolvable powdered drinks, candies (sweets), cakes, dried fruits, jams and other sweetened spreads, so called energy bars, milk shakes, etc.

Experts say it isn’t that you don’t eat any of these foods at all; what they are concerned about is their percentage to the content of your entire daily meal intake, and also if your entire meal chain revolves around these foods — as is the case with some people.

Eating a high-fructose diet over the long term alters your brain’s ability to learn and remember information.”

 So, instead of feasting on sugary snacks, try wholesome fruits.

Junk foods

As far as some people are concerned, patronising fast food joints is status symbol and therefore a sign of “arrival.” Well, that’s very contrary to commonsense, as scientists claim that the bad fats in junk foods can actually clog up the brain and interfere with the way it sends messages. The effects are even worse in growing children, they warn.

According to a study published in the Journal of Epidemiology and Community Health, the IQs of children who ate fatty, sugary, processed foods appeared to suffer years later, while the IQs of those who ate healthy foods increased.

Fried foods

Besides the fact that regularly eating fried foods can give men aggressive prostate cancer, scientists warn that their effects on brain function are as terrible.

A study by researchers at the University of the Basque in Spain, published in the journal Food Chemistry, revealed that compounds released from common cooking oils significantly increase the risk of neurologic degenerative diseases and a variety of different cancers. They conclude that toxic compounds from fried foods cause cancer and deteriorate brain health.

Experts also recommend alternate food preparation methods such as roasting, steaming and broiling.

Salty foods

Before now, scientists had made us know that too much salt and too little exercise are hard on the heart. However, new research suggests that they can be hard on the brain, too.

A three-year study of more than 1,200 people, led by Carol Greenwood, a nutrition scientist and interim director of the Baycrest Kunin-Lunenfeld Applied and Evaluative Research in Toronto, has linked a salty diet and sedentary lifestyle to cognitive decline in old age.

In fact, scientists say salt affects your brain the same way hard drugs do!

Of course, we don’t cut off salt from our diets totally; rather, what we need is a balance between things. So, a little salt is essential to good health.

Others brain killers

Other brain-killer foods to avoid include processed protein such as found in hot dogs, salami, sausages and processed meats; nicotine, as found in cigarette; alcohol, processed foods and artificial sweeteners.
