From a nutritional analysis point of view, sweet potatoes are not suitable for eating together with tomatoes.

The foods that are incompatible with tomatoes are as follows:

1. Sweet potatoes: Eating them together will cause stone disease, vomiting, abdominal pain, and diarrhea.

2. Carrots: The vitamin C in tomatoes will be destroyed by the decomposing enzymes in carrots.

3. Pork liver: Pork liver oxidizes and deoxygenates the vitamin C in tomatoes, losing its original ascorbic acid function.

4. Cucumber: Cucumber contains vitamin C decomposing enzyme. Eating it with tomatoes can destroy the vitamin C in tomatoes.

Lycopene is not only an important natural food colorant in today's industry, but more importantly, it is a strong antioxidant. Supplement lycopene to resist aging, enhance the immune system, and reduce the occurrence of diseases. Lycopene can also reduce the degeneration of macular spots in the eyes and reduce pigmentation. Therefore, tomatoes have the reputation of "longevity fruit".
