Recipes, habits and culinary tricks are often passed down from generation to generation. Mothers keep notebooks with advice from grandmothers, and later - share them with their own daughters. Such continuity is wonderful, but you should always remember that it can all become obsolete.
And the actions that we perform on the machine can bring not benefit, but harm. More information about what habitual techniques adversely affect health - in the article.

Habit 1: Try raw dishes

You need to wait until the products are heat treated, and then try.
Doctors believe that it is absolutely impossible to try food that is not fully prepared. Such food can contain bacteria that are usually destroyed under the influence of high temperatures. If you do not wait until this happens, there is a risk of contracting various infections. Especially this rule applies to lovers of minced meat (you need to try whether there is enough spices) and raw dough: it is very easy to catch salmonella from eggs or E. coli from flour.
Habit 2: Eat hot pastries

Bread should be allowed to cool.
Continuing the theme of baking, it is worth mentioning the habit of grabbing buns or pies from a baking pan without waiting for them to cool down. In this case, the state "with the heat of the heat" is not the best. Doctors say that even a piece of humpback, broken off from a bread roll that has not yet cooled, can adversely affect health. Hot and warm pastries provoke the fermentation process in the stomach, and if you abuse such dishes, inflammatory processes can begin. Another important nuance concerns the fact that our stomach as a whole can hardly digest bakery products, therefore, in order not to increase the load on it, it is better to eat cooled pastries.
Habit 3: Quench soda

Habit 4: Cook vegetables for too long

If vegetables are stewed for a long time, they will lose their useful properties.
There is nothing wrong with stewing or cooking vegetables until soft – they will not become harmful to health from this. However, the benefits will not bring either. The longer vegetables are heat treated, the paler they become and the more they lose vitamins and nutrients. The most useful for the body will be products that after cooking will remain slightly elastic and crispy. Keep this in mind when you cook carrots, broccoli and other vegetables.
Habit 5: Defrost meat at room temperature

Room temperature promotes the reproduction of bacteria.

8:

Wash the banana and then slice.
Even if your plans do not include eating fruits or vegetables along with the peel, they still need to be washed well before cutting, preferably rubbing with a brush so that there are no dirt and bacteria left. This applies to bananas, watermelons, melons, kiwis, etc. If you ignore this moment, thinking that it will come down, bacteria and microbes from the knife can easily get into the pulp of the fruit, provoking poisoning or other food problems.
Habit 9: Chop onions in advance

Onions should be chopped and immediately put in a frying pan, and not wait two hours
Cut onions long before cooking is not necessary. Here's why. First, the onion smell spreads through the kitchen at the speed of light, especially if there is no hood or the window is closed, and it is very difficult to get rid of it. Secondly, the chopped vegetable is likely to be bitter after cooking, which can spoil the taste of the dish. Therefore, chop the onions just before sending them to minced meat, salad or pan.
Habit 10: Heat the oil strongly in a frying pan

Do not wait for the oil in the pan to smoke.
"Wait until it smokes." Have you heard such a phrase from your mother or grandmother? Many housewives wait until the pan with oil heats up to the limit, and only then begin to fry the necessary products on it. Even though this habit is as old as the world, it is unsafe for health. Regular consumption of food cooked in hot oil can increase cancer of oncology - excessive heat treatment destroys antioxidants and at the same time provokes the formation of carcinogens. For the same reason, the oil must be changed after each use (by the way, in fast food restaurants, this rule is often neglected).
Frying technology in general is not too useful, so if possible it should be replaced with healthier and healthier options. We're talking about baking, stewing, frying in a non-stick pan without oil, steaming, etc.
