Food has many effects; just as there are foods that help with memory, there are also foods that can make you less smart! Have you ever felt that you are sometimes very forgetful or in an unusually low mood? This is exactly the result of your unhealthy diet! The following lists several foods that can make you "less smart," so take heed.
Bubble Gum
While the natural rubber in bubble gum is non-toxic, the primary white sheet gum used to make it contains additives such as vulcanization accelerators and antioxidants that are somewhat toxic. Eating too much of it is not good for your body.
Sweetened Fresh Orange Juice
Sweetened orange juice has even more calories and sugar than soda. It is recommended to eat whole fruit instead.
Century Eggs
Century eggs contain a certain amount of lead. Regular consumption can lead to lead poisoning in the human body. Symptoms of lead poisoning include insomnia, anemia, hyperactivity, and intellectual decline.
MSG (Monosodium Glutamate)
The daily intake of MSG should not exceed 6 grams per person. Excessive intake can increase the level of glutamic acid in the blood, which limits the body's ability to use calcium and magnesium. It can cause short-term symptoms such as headaches, palpitations, and nausea, and also has adverse effects on the human reproductive system.
Stinky Tofu
During the fermentation process, stinky tofu is highly susceptible to microbial contamination. It also contains large amounts of volatile basic nitrogen and hydrogen sulfide. It is a decomposed protein substance that is harmful to the human body.
Sunflower Seeds
Sunflower seeds contain unsaturated fatty acids. Eating too many of them can consume a large amount of choline, leading to disorders in the body's fat metabolism. A large amount of fat can accumulate in the liver, severely affecting the function of liver cells.
Pork Liver
Every kilogram of pork liver contains over 400 milligrams of cholesterol. Consuming too much cholesterol can lead to atherosclerosis, so it is not advisable to eat too much pork liver at one time.
Pickled Vegetables
Long-term consumption of pickled vegetables can cause sodium and water to be retained in the body, thereby increasing the risk of heart disease. Additionally, pickled vegetables contain carcinogens such as nitrosamines, and long-term consumption can easily induce cancer.
Popcorn
The lead content in popcorn is as high as about 10 milligrams per 500 grams, which is harmful to the human body, especially to the hematopoietic, nervous, and digestive systems of children.
Opening a bag of steaming hot popcorn, the rich, creamy aroma is always mouth-watering. But did you know? Eating too much popcorn can give you "popcorn lung."
Fish Jerky
Chewing fish jerky for too long can waste saliva, and swallowing a large amount of it can dilute gastric juice, reducing digestive capacity.
Youtiao (Chinese Fried Dough Stick)
The alum in youtiao is an aluminum-containing inorganic substance. If eaten daily, it is difficult for the body to excrete the aluminum through the kidneys. Excessive aluminum in the body can be toxic to the brain and nerve cells, and may even cause senile dementia.
Coffee
Coffee contains a relatively high amount of caffeine. Once ingested and digested, it quickly circulates with the blood, reaching all parts of the body within 5 minutes. It causes blood vessels to constrict, metabolism to speed up, and stomach acid and urine volume to increase.
