First of all, you need to know the fact that it is ok to eat less meat, but don't eat meat at all.
There are 20 kinds of amino acids that the human body needs, and 8 kinds that the human body cannot synthesize, which need food to supplement. In meat, animal protein contains more amino acids than plants ... and it is said that some vitamins are only available in meat. Meat is rich in vitamins and minerals. In protein, plant protein is different from animal protein, and the proportion of amino acids is also different. Secondly, animal fat is one of the basic nutrients that our human body needs to supplement. As for vitamins, they are more abundant in plants, but meat has many supplementary minerals and other trace elements, which are beneficial to health.
However, eating too much meat is bad for your health, such as cholesterol and acidic substances! Moderation is king.
So you should let your mother know that you will eat meat properly, but you should choose which kind to eat and when to eat it. What kind of meat do you dislike? In addition, communicate well with parents and say that in order to avoid waste, don't cook food that you don't like. Everything should be moderate, and eating it will also cause physical problems. For example, eating too many eggs a day will also lead to nosebleeds. Delicious and expensive things are not necessarily suitable for everyone. You should choose how to eat and drink according to your physical condition.
I hope my suggestion is helpful to you.
