Foods that 'meet' are harmful

[P-1]

Mr. Tran Dang, former director of the Department of Food Safety and Hygiene, has recommended not to share some food pairs, because it can make food lose nutrients, difficult to digest...

Referring to soy milk and chicken eggs, people often think that these are two foods rich in protein, very good for the elderly, debilitated patients... But this pair of foods should not be used together, because in milk Soybean has protidaza to inhibit protein in chicken eggs, affecting digestion, causing indigestion, bloating.

And orange juice and cow's milk should not be drunk together. If you have time, try to do a little experiment by pouring a glass of orange juice into cow's milk and you will see, almost immediately, precipitation will occur.

It is the result of the reaction between pectic acid in orange juice, tangerine with casein in cow's milk. That precipitated mixture of milk and orange juice will be very difficult for the stomach to digest.

Therefore, if anyone drinks two types of water at the same time, they will find their stomach rumbling, warm and very uncomfortable. To avoid that, it is best to drink each type separately with a certain interval.
 
If you must drink at the same time, you should drink cow's milk first and then drink orange juice. At that time, the milk has been partially hydrolyzed when mixed with stomach acid, so there is no harm in meeting orange juice.

Protein with calcium also needs to be added in a rhythmic manner. If too much protein is present at the same time as calcium in the intestinal lumen, it will reduce calcium absorption and increase calcium excretion through the kidneys.

For example, in milk, the amount of protein and calcium are in balance for best absorption. Thus, those who want to preserve calcium for their body without osteoporosis should not eat fish and drink milk together. Get into the habit of using milk and snacks in the afternoon around 9am and 3pm.

Phosphorus is present in a lot of red meat (pork, beef, sheep...), legumes... also helps to increase calcium absorption if the ratio in the intestine is one phosphorus/two calcium. Phosphorus increases or decreases more than this ratio both reduce calcium absorption. In addition to natural foods, phosphorus is also abundant in industrial drinking water.

Therefore, do not drink milk and soft drinks less than two hours apart. Many people use milk to take medicine, this is not recommended because milk creates an alkaline environment, in milk there is also a lot of potassium, iron, etc., which interferes with drug absorption, affecting the treatment results.
 
Doctor Nguyen Thi Hoa, Head of the Department of Nutrition - Children's Hospital 1 suggested that mothers should not mix fruit and vegetable juice with milk for their children to drink because in the long run, they will suffer from Methemoglobin disease (a disease that causes difficulty breathing, cyanosis). pale and death), and do not feed children with pig brains with eggs because it will increase blood cholesterol, which can lead to death from high blood pressure.

Sweet potatoes and persimmons are food pairs that should be avoided. Many people know that sweet potatoes contain a lot of sugar and starch when entering the stomach, causing the stomach to secrete more hydrochloric acid. Persimmons contain tannin (acrid taste) when in the stomach will convert into tannic acid.
 
If hydrochloric acid binds with the astringent and some substances in the persimmon, it forms a deposit. Under the effect of acid and stomach kneading, this substance is stable, insoluble, causing indigestion and especially difficult to excrete, which can lead to kidney stones.
 
According to Dr. Nguyen Thi Lam, deputy director of the Institute of Nutrition, there are a number of foods that compete for nutrients with each other. For example, foods rich in calcium combine with iron (Fe) to reduce absorption. Or after eating, you should not drink solid tea, because the tannins in the tea will reduce Fe absorption. Eating salty will reduce potassium absorption, eating excess protein will convert calcium out...
 
People with constipation are often advised to drink plenty of water. However, stay away from drinking tea when eating dog meat. The tannic acid in the tea, when it interacts with the protein in the meat, astringents the intestinal lining, reduces intestinal motility, causing the intestines to accumulate many harmful substances, making the stool dry and easy to be constipated.
 
In addition, do not let white radish and pears, apples, grapes meet in the stomach. When entering the stomach, the cianogen acid salts and sulfur in the radish will be converted into cianogen acid, which affects the thyroid gland.
Apples and grapes have co-ketones, which are easily broken down by bacteria into OH-based benzoic acid. If radish is eaten at the same time as this fruit, this acid increases the pressure of sulfur cianogen, causing hypothyroidism.
 
Tannins in acrid plants such as tea, guava ... prevent the absorption of most micro-minerals such as iron, zinc, copper... Therefore, it is not recommended to drink solid tea after eating foods rich in micro-minerals such as seafood. seafood, seaweed, red meat… at least two hours.
 
This time is needed so that the two incompatible substances do not "get together" in the same place. As a result, nutrients are absorbed to the maximum extent by the body.

Phytates in starches and oxalates in undercooked vegetables reduce the absorption of iodine in seafood and sea salt. Many people mix fish salad, seaweed salad with raw cabbage, broccoli, and broccoli. This should not be, because precious iodine will "fly without wings". If you like to mix with these vegetables, dip them in boiling water or pickle them.

As for Oriental medicine, General Practitioner Phung Tuan Giang, Tho Xuan Duong Pharmacy said: There are medicines and foods that are not used together or need to be taboo when using drugs. Like licorice not used with seaweed (seaweed)

When using Oriental medicine, do not eat morning glory, green beans will lose the effect of the drug.

Using Oriental medicine to treat pain, you must abstain from shrimp, crab, and chicken because it is easy to cause movement and increase pain.
