The brain is the most important organ of our body. Some foods have negative effects on the brain. memorize and mood and increase the risk of dementia. Estimates predict dementia will affect more than 2030 million people worldwide by 65.
It is possible to reduce the risk of disease by avoiding certain foods. Request foods harmful to brain health...
What Foods Are Harmful to the Brain?
Sugary drinks
Sugary drinks, soda, sports drinks, energy drinks and beverages such as fruit juice. High intake of sugary drinks not only enlarges the waistline but also increases the risk of type 2 diabetes and heart disease - it also negatively affects the brain.
Excessive intake of sugary drinks increases the risk of Alzheimer's disease, while also increasing the risk of type 2 diabetes. In addition, high blood sugar levels increase the risk of dementia, even in people without diabetes.
High fructose intake can cause obesity, high blood pressure, high blood fats, diabetes, and arterial dysfunction.
Animal studies show that high fructose intake insulin resistancewhat it can lead to, as well as causing a decrease in brain function, memory, learning, and formation of brain neurons.
A study in rats found that high sugar intake affected brain inflammation and impaired memory.
Refined carbohydrates
Refined carbohydrateshighly processed foods like sugar and white flour. These types of carbohydrates usually have a high glycemic index (GI).
This means that it will cause an increase in blood sugar and insulin levels that our bodies will digest them fast.
A study in healthy college students found that those who consumed high amounts of fat and refined sugar had poorer memory.
This effect on memory is due to the hippocampus, which is a part of the brain that affects some aspects of memory, as well as responding to cues of hunger and satiety.
Inflammation is recognized as a risk factor for degenerative diseases of the brain, including Alzheimer's disease and dementia.
Carbohydrates can also have other effects on the brain. For example, one study found that children ages six to seven who ate highly refined carbs scored lower on nonverbal communication.
Foods high in trans fats
Trans fatsis a type of unsaturated fat that can be harmful to brain health. While trans fats are found naturally in animal products such as meat and milk, they are not a major concern. Industrially produced trans fats, also known as hydrogenated vegetable oils, pose a problem.
Studies have found that if people consume larger amounts of trans fat, they tend to increase the risk of Alzheimer's disease, poor memory, low brain volume, and cognitive decline.
However, high consumption of omega 3 fatty acids have been found to help protect against cognitive decline. Omega 3 increases the secretion of anti-inflammatory compounds in the brain, and this has a protective effect especially in older adults.
The fish, chia seeds, flax seed and by consuming foods such as walnuts, omega 3 fat intake can be increased.
Highly processed foods
Highly processed foods are high in sugar, fat and salt. These are generally high in calories and low in nutrients. They are foods that can negatively affect brain health.
A study of 243 people finds that the increase in visceral fat accumulated around organs is associated with brain tissue damage.
Another study in 130 people found a measurable reduction in brain tissue even in the early stages of metabolic syndrome.
The nutritional composition of processed foods can adversely affect the brain and cause the development of degenerative diseases.
A study involving 52 people found that unhealthy foods resulted in lower levels of sugar metabolism and a decrease in brain tissue. These factors are thought to be markers of Alzheimer's disease.
Another study involving 18.080 people, fried foods and found that processed meats were associated with lower scores in learning and memory.
In another study, the blood-brain barrier was disrupted in rats fed high-calorie foods. The blood-brain barrier is a membrane between the brain and the blood supply for the rest of the body. It helps protect the brain by preventing some substances from entering.
Processed foods can be avoided by eating mostly fresh, foods such as fruits, vegetables, nuts, seeds, legumes, meat and fish. In addition, a Mediterranean-style diet is known to protect against cognitive decline.
aspartame
Aspartame is an artificial sweetener used in many sugar-free products. People often use it when they are trying to lose weight or when avoiding diabetes in diabetes.
This commonly used sweetener has been associated with behavioral and cognitive problems.
Aspartame consists of phenylalanine, methanol and aspartic acid. phenylalanine It can cross the blood-brain barrier and disrupt the production of neurotransmitters. Also, aspartame is a chemical stressor and may increase the brain's vulnerability to oxidative stress.
One study looked at the effects of high aspartame consumption. Participants consumed aspartame for eight days. At the end of the study, they were more restless, had a higher rate of depression, and performed worse on mental tests.
A study of repeated aspartame intake in mice found that impaired brain memory and increased oxidative stress. Another revealed that prolonged intake led to an imbalance in the antioxidant status of the brain.
Alcohol
Excessive consumption of alcohol can have serious effects on the brain. Chronic alcohol use causes brain volume, metabolic changes, and disruption of neurotransmitters, chemicals used for communication in the brain.
People who are addicted to alcohol often have a vitamin B1 deficiency. This can lead to a brain disorder called Wernicke's encephalopathy, which can develop into Korsakoff syndrome. This syndrome can cause serious damage to the brain, including memory loss, visual disturbances, mental confusion, and instability.
Alcohol consumption during pregnancy can have devastating effects on the fetus. Given that the brain is still developing, the toxic effects of alcohol can cause developmental disorders such as fetal alcohol syndrome.
Another effect of alcohol is disruption of sleep patterns. Drinking large amounts of alcohol before going to bed is associated with poor sleep quality, resulting in chronic to insomnia why could it be.
Fish with high mercury content
Mercury is a heavy metal and neurological poison that can be stored in animal tissues for a long time. Perennial predators are particularly susceptible to collecting mercury and can transport 1 million times the concentration of surrounding water.
After a person takes mercury, the body spreads it, concentrating it in the brain, liver, and kidneys. It is also concentrated in the placenta and fetus in pregnant women.
The effects of mercury toxicity include disruption of the central nervous system and neurotransmitters, and stimulation of neurotoxins, damaging the brain.
Mercury can impair brain development and cause cell components to be destroyed for the developing fetus and young children. This can cause cerebral palsy and other developmental delays.
However, most fish are not a significant source of mercury. In fact, fish is a high-quality protein and contains many important nutrients such as omega-3, vitamin B12, zinc, iron, and magnesium. Therefore, eating a fish must.
Generally, it is recommended that adults eat two to three servings of fish per week. However, if you are eating shark or swordfish, eat only one serving and don't consume any other fish that week.
Pregnant women and children should avoid high-mercury fish such as shark, swordfish, tuna, king mackerel, and black fish. However, eating two or three servings of other low-mercury fish is safe.
