Improper food collocation can lead to diseases.
Seafood and beer are prone to gout. Seafood contains purine and monophosphate, while beer is rich in vitamin B 1, which is an important catalyst for decomposing these two components. If you drink beer while eating seafood, it will promote the combination of harmful substances in the body and increase the uric acid content in human blood, thus forming urinary calculi that are difficult to excrete. If there is something wrong with your metabolism, drinking beer while eating seafood can easily lead to a sharp increase in uric acid levels in the blood, which will lead to gout.
Gouty nephropathy, gouty arthritis and so on.
Ham and lactic acid drinks are easy to cause cancer. People who often eat sandwiches and yogurt for breakfast should be careful. Lactic acid drinks (including organic acids) such as ham and bacon in sandwiches are easy to cause cancer. Because, in order to preserve sausages, ham, bacon, bacon and so on. Food manufacturers will add nitrates to prevent food spoilage and the growth of Botox. When nitrate meets organic acids (lactic acid, citric acid, tartaric acid, malic acid, etc. ), it will be converted into a carcinogen-nitrosamine. Therefore, don't eat this kind of processed meat products often, so as not to increase the risk of cancer.
Radish and orange are easy to induce goiter. Radish will produce an antithyroid substance thiocyanic acid. If a large number of fruits such as oranges, apples and grapes are eaten at the same time, flavonoids in fruits will be converted into thiocyanic acid that inhibits thyroid function after bacterial decomposition in the intestine, thus inducing goiter.
Eggs and soybean milk reduce protein's absorption. Raw soybean milk contains trypsin inhibitor, which can inhibit the activity of human protease and affect the digestion and absorption of protein. The egg white of eggs contains viscous protein, which can combine with trypsin in soybean milk, so that the decomposition of protein is blocked, thus reducing the absorption rate of protein.
Milk and chocolate have diarrhea easily. Milk is rich in protein and calcium, while chocolate contains oxalic acid. When they are mixed together, calcium in milk will combine with oxalic acid in chocolate to form a kind of water-insoluble calcium oxalate, which will not be absorbed after eating, and will also cause symptoms such as diarrhea and dry hair, thus affecting people's growth and development.
Fruits and seafood are not easy to digest. When eating seafood, if you eat grapes, hawthorn, pomegranate, persimmon and other fruits, you will have symptoms such as vomiting, bloating and diarrhea. Because these fruits contain tannic acid, when tannic acid meets protein in aquatic products, it will precipitate and solidify to form indigestible substances. After eating seafood, people should eat this fruit more than 4 hours apart.
Spinach and tofu are prone to lithiasis. Tofu contains magnesium chloride and calcium sulfate, and spinach contains oxalic acid. When they meet, they can produce magnesium oxalate and calcium oxalate. These two kinds of white sediments can not only be absorbed by human body, but also affect the absorption of calcium by human body, which is prone to lithiasis.

Eating Chili peppers should be selected according to the region.
Nowadays, spicy has become an indispensable taste in the diet of northerners. Look at Sichuan cuisine and Thai cuisine all over the street. They all have different degrees of spicy taste. But experts warn that northerners eating spicy food may hurt their eyes.
Because of different constitutions, there are differences in eating spicy food.
Due to the different climate between the north and the south, there are also differences in human physique. For example, northerners have strong gastrointestinal function, while southerners have weak gastrointestinal function. According to Dr. Zhao Zhifu, director of psychosomatic medicine department of Guang 'anmen Hospital of Chinese Academy of Traditional Chinese Medicine, northerners are internally hot and externally cold, while southerners are internally cold and externally hot. For the eyes, I am most afraid of getting angry.
Therefore, eating spicy food without restraint may directly hurt the eyes: first, it will make the eyes feel burning and the blood vessels of the eyeball congestion, leading to unclear vision. Long-term spicy stimulation will lead to conjunctivitis, fundus arteriosclerosis, dry eye and decreased vision and other senile diseases in advance.
So what kind of people are not suitable for spicy food?
Dr. Zhao reminded that people with red face, constipation, yellow urine and bloodshot eyes should not eat spicy food. People with bad temper should not eat spicy food. People from the south to the north, influenced by the climate and environmental changes in the north, have gradually changed their physique, so they should also change their habit of eating spicy food.
