This statement is not entirely accurate. Nutrition is not only found in the meat, but also in the soup. Specifically:

1. Meat itself is rich in protein, fat, minerals and other nutrients, most of which are retained in the meat during the stew process, so the nutritional value of the meat will not be lost too much. However, some of the water-soluble vitamins such as vitamin C in the high temperature heating for a long time will have a certain loss.

2. stew process, meat and other ingredients in the part of the nutrients will be released into the soup, such as sugar, minerals, amino acids. A long time of stewing can make these nutrients fully released and integration, so the stew soup also has a certain nutritional value.

3. The stew also contains dietary fiber and other nutrients in the soup. Meat and vegetables in a long time heating, part of the dietary fiber and other nutrients will be integrated into the soup, which also increases the nutritional density of the soup.

4. Stew in the soup added to the dishes, vegetables also provide nutrition for the soup. Vegetables like carrots, potatoes, beans, etc. are rich in nutrients, and some of these nutrients are also incorporated into the soup, increasing its nutritional value.

So, in summary, we can conclude that meat is indeed rich in nutrients, but the process of stewing the soup will also release a certain amount of nutrients to the soup, while adding the vegetables also provide nutrients for the soup. Therefore, when you make soup, the nutrients are not only in the meat, but also in the soup. The correct way to say it is: when you make soup, both the meat and the soup have nutritional value. Both the soup and the meat are nutritious and complement each other.

Ideally, when enjoying a stew, you want to eat both the meat and the soup to maximize the nutrients in the food. Eating the meat alone or drinking the soup alone will not provide the full nutritional benefit. So that's an inaccurate assertion, the nutrition of the stew comes from the meat and the soup, both of which are indispensable.
