The natural rubber in bubble gum is non-toxic, but the primary white crepe rubber used to make it contains additives such as vulcanizing accelerators and antioxidants that are somewhat toxic. Eating too much of it is not good for your health. 2. Sugared Fresh Orange Juice
Sugared orange juice has even more calories and sugar content than soda. It is recommended to eat fresh fruit 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 protein and is harmful to the human body. 5. MSG
The daily intake of MSG per person should not exceed 6 grams. Excessive intake can increase the level of glutamic acid in the blood, which limits the body's ability to utilize 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. 6. Sunflower Seeds
Sunflower seeds contain unsaturated fatty acids. Eating too many of them can deplete large amounts of choline, disrupting the body's fat metabolism and causing a large accumulation of fat in the liver, which can seriously affect the function of liver cells. 7. Pork Liver
Every kilogram of pork liver contains over 400 milligrams of cholesterol. Consuming too much cholesterol can lead to atherosclerosis, so one should not eat too much pork liver at a 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 long-term consumption can easily induce cancer. 9. Popcorn
The lead content in popcorn is as high as about 10 mg per 500 grams, which is harmful to the human body, especially to the hematopoietic, nervous, and digestive systems of children. 10. Fish Slices
Chewing fish slices for too long can waste saliva, and swallowing a large amount of it can dilute gastric acid, reducing digestive capacity. 11. Fried Dough Sticks
The alum in fried dough sticks is an aluminum-containing inorganic substance. If eaten daily, aluminum is difficult to excrete from the kidneys. An excessive amount of 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 relatively high amount of caffeine. Once ingested and digested, it quickly enters the bloodstream and reaches various organs of the body within 5 minutes, causing vasoconstriction, increased metabolism, and increased gastric acid and urine production.
