Foods that kill intelligence: You need to avoid
Just as some foods are bad for your body, some foods are also bad for your brain. If you want to be healthier and smarter at the same time, skip foods that impair cognitive function. When it comes to nutrition, it must be mentioned that there are all sorts of foods: some super-foods are your greatest allies against extra pounds, while others stimulate your cognitive function and improve your memory. On the other hand, some foods are known to have a devastating effect on your brain functioning, and nutritionists advise us to consume them moderately in order to limit their negative impact. Avoid the following list of unhealthy foods that kill your brain:
It's a well-known fact that alcohol isn't exactly good for your brain. In fact, it impairs judgment, slows reaction time, messes with you memory, and disrupts the growth of new brain cells.
Sugar and artificial sweeteners
Sugar is bad for your memory. Recent scientific research has shown that eating too much sugar decreases the level of the brain chemical BDNF or brain-derived neurotrophic factor, which helps your brain form memories. Without it, your brain is unable to retain information and learn much of anything. Low levels of BDNF are also linked to depression and dementia.
A study found that eating junk food can mess with your dopamine levels and production in the body. This means that the hormone that makes you 'happy' is directly affected by eating too much junk. Not to mention, empty calories lack the nutrients your brain needs to think properly, such as essential vitamins and minerals. Any foods devoid of real nutrition should be avoided in order to keep the brain sharp.
Processed foods contain additives, dyes, preservatives, and artificial flavours that interrupt normal bodily functions. That is because these ingredients aren't exactly edible. Many artificial ingredients used in processed foods can actually cause memory loss and damage to your central nervous system. Stay away from foods with an extended shelf life or that come out of the box or freezer bag.
High sodium foods
Not only are salty foods bad for your blood pressure, studies show that a high sodium diet impairs cognitive function. Salty foods also make you crave more salt, which changes your perception and ability to resist hunger. Food can seriously become one big distraction when you consume too much salt.
Eating things with gluten or a high glycemic index may cause symptoms such as, dementia, decreased libido, depression, chronic headaches, anxiety, and epilepsy.
Stay away from processed meats that may contain preservatives or sodium nitrate. The list includes hotdogs; salami, bacon, lunchmeat, and sausage are all processed meats. In addition, keep in mind that many meats that come from industrial scale farms contain remnants of large scale animal processing. That is, many animals in industrial farms are treated with antibiotics or hormones, which end up in the meat that you eat. These 'extra' ingredients increase the risk of cancer by introducing the body to the toxins called free radicals.
Trans-fats are to be avoided at all costs because they not only cause weight gain, they kill brain cells. Trans fats- elevate cholesterol, clog your arteries with cholesterol, and put you at higher risk for a stroke.
Many don't realize this, but fast food contains a ton of sugar, additives, and preservatives. Not only does it make you crave more of the food, it may introduce your body to free radicals through artificial ingredients.
Many fried foods not only contain MSG (monosodium glutamate), they also clog your arteries. MSG is a controversial ingredient that has been linked to brain damage, and clogged arteries may lead to permanent brain damage through a stroke. Too much glutamate may result in neuron death and disrupt neurological processes in the body.
Despite the fact that nicotine is not really a food product, it still wreaks havoc on your brain by restricting the blood flow to this important organ, along with the regular flow of glucose and oxygen. Nicotine not only causes premature aging, bad breath and poses an increased risk for lung cancer, but it also affects the production and the function of neurotransmitters by tightening the capillaries, the tiny blood vessels that play a pivotal role when it comes to your brain function.
By avoiding these foods, you might just feel the effects of faster reaction time, better memory, and focus in concentration.
