Nothing is healthy to eat now, only what you grow is the best?

Now, we really need to seriously consider what we eat every day. We need to use oil for cooking every day, but there are many kinds of oil, and there are not so many that can really meet the standard. Some "black-hearted" bosses also cook with waste oil, which really harms our health. The vegetables we eat every day have different levels of pesticide residues, which will affect our health. For example, there are additives in flour, and a lot of fertilizers are applied to whitening agent corn. And so on _ In contrast, we grow grain and vegetables that are pure green, pollution-free, and do not use chemical fertilizers and pesticides, so they are safe to eat.
