Tomatoes are a member of the deadly nightshade family, and as such were considered toxic, causing many conditions like appendicitis, “brain fever” and cancer.

In fact, they may have just the opposite effect. Tomatoes were not even eaten in the US until the early 1800s, when an eccentric New Jersey gentleman Colonel Robert Gibbon Johnson brought them back from a trip overseas.
Always one to take advantage of a dramatic opportunity, he announced an amazing display of courage would take place on September 26, 1820. He shocked his hometown of Salem by consuming and entire basket of tomatoes in front of a crowd of spectators, expecting him to keel over any second. Obviously, he didn’t and since then tomatoes have been a staple of the American diet and with good reason.
Starting with the basics, tomatoes contain large amounts of vitamin C, providing 40 percent of the daily value (DV). They also contain 15 percent DV of vitamin A, 8 percent DV of potassium, and 7 percent of the recommended dietary allowance (RDA) of iron for women and 10 percent RDA for men.
