There are many eating habits which are very common in our daily life, but at the same time, they are very harmful to our health. Following are some typical examples of these bad habits.

First, adding soybean milk in the eggs
The mucous protein in eggs will combine with the trypsin in soybean milk, which will make the food lose its original nutritional value.

Second, boiling eggs with tea leaves
In addition to alkaloids, tea leaves also contain a lot of acid materials. These acid materials will combine with the iron in eggs, which will not only cause certain stimulus on the stomach, but also is not conducive to digestion and absorption.

Third, cooking potatoes with beef
As the concentration of the gastric acid required by these two foods is different, it is bound to extend the residence time of the food in the stomach, so the stomach will need much more time to digest and absorb the food, which will increase the burden on the stomach.

Fourth, drinking milk together with oranges
Some people like drinking milk together with some acidic fruits such as oranges, or eating oranges immediately after they have drunk milk. Such habits will make the proteins in milk and the tartaric acid in orange combine together and concrete into block. This will affect the digestion and absorption of the food, and also may cause bloating and abdominal pain.

Fifth, eating carrot when drinking alcohol
A recent study from the American nutrition experts suggests that, if the B carotene and alcohol enter human body at the same time, it is extremely easy to produce some toxins which are very harmful to human health in the liver. These toxins are the dangerous factors which may induce various types of liver diseases.

Sixth, long-term consumption of vegetable oil
Through some relevant researches, the experts believe that, peanut oil and corn oil contain a strong carcinogen called as aflatoxin. And cottonseed oil contains the toxic substance called as gossypol, which may easily cause chronic poisoning to people. What's more, the erucic acid contained in rapeseed oil is very detrimental for the health of the patients who suffer from hypertension and heart disease. As a result, the experts suggest that people should change the habit of long-term consumption of vegetable oil. When they cook the food, they can try to appropriately increase the use of animal fats, so as to reduce the harms brought by vegetable oil.
