It is obvious that avocados and dark chocolate are the most delicious and healthiest foods for both our brains and bodies. But unfortunately, not all of us have developed the habit of consuming these foods daily. Instead, we are most likely attracted to the ones that are not healthy and ready to sap our smarts.
So only if you want to be forgetful, sluggish, and maybe even depressed then you can consume these foods. Otherwise, it is best to avoid them completely because we are nothing without our brains, literally. So we really need to take great care of them.
According to a research from the University of South Florida, people with high levels of mercury in their bloodstream (the amount that the Environmental Protection Agency deems safe) are 5% dip in cognitive function.
However, this doesn’t mean that all seafood is dangerous, it is the total opposite. For example: sardines, salmon, and mackerel are high in omega-3s that is very healthy for the brain. Plus, it is low in mercury.
In any case, you may consume
When you realize that the average American consumes 79 pounds of added sweeteners per year, you will actually realize how messed up our diets are, because these stuff can spike up your insulin and cause inflammation that will result in both vascular and neuronal damage.
According to a study, the brain’s memory control center, the hippocampus, can become inflamed and lose its ability to work due to the large amounts of sugar. On the other hand, there is another study that discovered depression to be strongly linked to high sugar intake.
In order to avoid them, make sure to study the labels of the products you are purchasing, if you find “see sugar” listed as one of the first ingredients, then it’s a sign that the product is high in added sugar.
Technically, Fructose is sugar, but any food that is high in this particular type of sugar is going to affect the brain negatively, not like the regular table sugar.
There is a research that was published in Journal of Physiology that explained what happened to rats that were exposed to different diets of sugar. The ones that were high in Fructose were placed in a maze that they had already mastered, but somehow they had problems figuring it out.
According to researchers, the fructose could affect the way our brain cells use and store the sugar for the energy that is required to process thoughts and what we learn. The only fructose that is healthy is the one we can find in fruits.
Partially Hydrogenated Oils
Okay here is the truth, there is no reason to consume foods that are listed in partially hydrogenated oils because they increase the risk of suffering from obesity and damaging your heart health, which leads to a serious brain issue like the Alzheimer’s disease.
Meanwhile, another study found that people who eat high levels of these oils had smaller brains and low cognitive abilities later in their lives. These oils are included in baked goods, fried and processed foods.
Speaking of the processed foods, these ones are not really high in sugar or fat, but they are high in sodium. According to the National Health and Nutrition Examinations Surveys, the top 10 foods that lead to Americans’ high sodium intake are mostly the processed foods.
Another research found out that foods that are high in sodium are basically brain fog. Plus, it is strongly linked to our blood pressure and heart health. In conclusion, these foods are not healthy at all, and it is best to avoid them once and for all.
We don’t need to introduce this one because we all know how unhealthy and dangerous fast food could be. It is literally the house that holds all the bad ingredients for the brain in high doses:
Trans fat, sugar, sodium, saturated fats, etc. According to a recent research, people who consume fast food have a higher risk of developing depression than those who rarely eat it, the risk is 40% higher!
Sadly, no matter how bad these foods are, people will still choose to consume them because they are delicious, literally fast, and cheap.
This one is in a “meh” situation because they are kind of okay, but a diet high in them can be very harmful in the long and short-term. Saturated fats can decrease the brain’s ability to form new memories and learn new things.
Also, they can affect the brain’s fight against Alzheimer’s causing brain plaque, which is a build-up that occurs outside the nerve cells. In other words, it is very toxic to neurons in the brain.
Copper and Iron Supplements
The only time you should consume these supplements is when a physician tells you to, that’s it. Because according to a Neurobiology of Aging says that these minerals are good for our health, but not when it is consumed way too much.
Excessive copper and any other heavy metals like iron can affect the clearance of beta-amyloid, which is a type of plaque that can lead to killing many nerve cells in the brain.
Without the doctor’s guidance, you may consume way more supplements than you need that will suddenly cause issues that your brain will not appreciate.
