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 that have a certain degree of toxicity. Excessive consumption can be harmful to the body.
2. Sweetened Freshly Squeezed Orange Juice
Sweetened orange juice has even more calories and sugar than soda. It is recommended to eat whole fruit instead.
3. Century Eggs (Preserved 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 impairment.
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 putrid substance that decomposes proteins and is harmful to the human body.
5. Monosodium Glutamate (MSG)
The daily intake of MSG should not exceed 6 grams per person. Excessive intake can raise 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 can deplete a large amount of choline, disrupt the body's fat metabolism, and cause a large amount of fat to accumulate 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 it is not advisable to eat too much pork liver 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. In addition, 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/500g, 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 large amounts of it can dilute gastric juice and reduce digestive capacity.
11. Fried Dough Sticks (Youtiao)
The alum in fried dough sticks 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 then 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 circulates in the blood and reaches various organs of the body within 5 minutes, causing blood vessels to constrict, metabolism to speed up, and gastric acid and urine volume to increase.
