Earthworms and fish contain a thiamine substance that can destroy vitamin B1. Therefore, fish and sputum should not be eaten when taking vitamin B1.
High-fiber foods can increase bowel movements and speed up the passage of intestinal contents, thereby reducing the absorption rate of vitamin B2; high-fat diets increase the demand for vitamin B2, thereby aggravating the deficiency of vitamin B2. Therefore, high-fat foods and high-fiber foods should be avoided when taking vitamin B2.
