Potatoes can't be cooked with tomatoes because some people will eat green or sprouted potatoes. This kind of potato contains more toxins. Not only is it not recommended to match with tomatoes, but it is also not recommended to eat this potato. In addition, when choosing tomatoes, please choose ripe red tomatoes instead of immature green tomatoes. First of all, the view that "food and nutrition are incompatible" is untenable. The tomatoes mentioned above can't be eaten with cucumbers, potatoes and mushrooms. I've eaten all these. I think not only I have eaten, but many people have eaten, such as you.
There is a cold dish in northwest Shandong in summer, that is, tomatoes with cucumbers, and a home-cooked dish, that is, tomatoes, potatoes and onions are fried together, mushrooms and tomatoes are in soup noodles, mushrooms are in a pot, and ketchup may be added to noodles. It is said on the Internet that tomatoes and cucumbers can't be eaten together, because there are vitamin C decomposing enzymes in cucumbers, which can decompose vitamin C in tomatoes. It's weird. According to what you said, the vitamin C decomposing enzyme in cucumber should first decompose the vitamin C contained in it. Don't break down with its food at the same time. What are the benefits of eating cucumbers?
This view is unreasonable. After the vitamin C decomposing enzyme in cucumber enters the intestine, it will be diluted by gastric acid and lose its activity, which will not destroy the vitamin C in tomato at all. As long as tomatoes can be eaten alone, potatoes can also be eaten alone. There is no problem in combining the two. Potatoes are rich in resistant starch, dietary fiber and potassium, while tomatoes are rich in vitamin C and lycopene. They are complementary in nutrition and cannot be mutually denied. And potatoes will produce a lot of hydrochloric acid in the intestines, which is even more unreasonable. People's stomachs are very sour and don't pay attention to what to eat, and the weak alkalinity in the intestines doesn't pay attention to what to eat.
