For eating a variety of foods, the key is to get a variety of nutrients. We can see this by taking a look at how different vegetables and fruits look when they’re grown in soil versus a field. These are called the “Brassicaceae” and “Solanaceae” plants, and we can see from this how they get different vitamins and minerals. Here’s an example of spinach growing in a field, and another of kale.
