If you’re interested in controlling what goes into your food and into your body, try growing some heirloom tomatoes organically. Abundant in vitamin C, biotin, vitamin K, and carotenes, tomatoes are easier to grow than you think, and less costly to your wallet and the environment. I grow all kinds of heirloom varieties in my backyard. It’s fun to see all the different colors pop, and the flavors are so distinctive. If you can’t grow your own, try to buy organic varieties because the residual pesticide level on tomatoes is rather high. Also, unripe fruit is generally not as nutritionally rich as ripe fruit, so go for good color and a uniform and firm texture.   MARIA DESIDERATA MONTANA
