1. Bubble Gum
Although the natural rubber in bubble gum is non-toxic, the primary pale crepe rubber used to make it contains additives such as vulcanization accelerators and antioxidants, which are somewhat toxic. Excessive consumption is detrimental to health. 2. Sugary Freshly Squeezed Orange Juice
Sugary orange juice contains even more calories and sugar than soda. It is recommended to eat whole fruits instead. 3. 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 diminished intelligence. 4. 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 putrefactive substance that breaks down proteins and is harmful to the human body.
5. Monosodium Glutamate (MSG)
The daily intake of MSG per person should not exceed 6 grams. Excessive consumption can increase the level of glutamic acid in the blood, which limits the body's ability to utilize calcium and magnesium. This can cause short-term symptoms such as headaches, palpitations, and nausea, and also has adverse effects on the human reproductive system. 6. Sunflower Seeds
Sunflower seeds contain unsaturated fatty acids. Eating too many can consume large amounts of choline, disrupting the body's fat metabolism and causing a large accumulation of fat in the liver, which severely impairs liver cell function. 7. Pork Liver
Every kilogram of pork liver contains over 400 milligrams of cholesterol. Consuming too much cholesterol can lead to atherosclerosis, so pork liver should not be eaten in large quantities at one time. 8. 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 nitrosamines, a carcinogenic substance, and prolonged consumption can easily induce cancer.
9. Popcorn
The lead content in popcorn is as high as about 10 mg/500g, which is harmful to the human body, especially to the hematopoietic, nervous, and digestive systems of children. 10. Fish Jerky
Chewing fish jerky for too long can waste saliva, and the large amount of saliva swallowed can dilute gastric juice, reducing digestive capacity. 11. Fried Dough Sticks (Youtiao)
The alum in fried dough sticks is an inorganic substance containing aluminum. 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 lead to senile dementia. 12. Coffee
Coffee contains a significant amount of caffeine. Once ingested and digested, it quickly enters the bloodstream and reaches all organs of the body within 5 minutes, causing vasoconstriction, increased metabolism, and higher levels of gastric acid and urine.
