Food allergies are relatively common. some people are allergic to food items in the same plant family.

For example I have a client who gets a rash that looks like poison ivy if he eats cashews or mangos. It is interesting to note that Cashew Nuts, Poison Ivy, Pistachio Nuts and Mangos are all in the same plant family.

Some people have sensitivity to the nightshade family (Solanaceae) of plants, which includes Eggplants, Tomatoes, Pimentos, Garden Peppers (green, red, chili, paprika) and Potatoes (Irish). These people are commonly sensitive to tobacco smoke as well, since tobacco is also part of the nightshade family.

People sensitive to nightshades can sometimes eat potatoes because potatoes are roots as opposed to the fruit of the plant. Typically, sweet potatoes and yams are fine because they are part of a different plant family, related to morning glories.

The following is a list of foods and how they are related.

The family includes many edible sala plants (e.g., lettuce, endive, chicory and artichoke), cultivated species such as the marigolds, daisies, sunflowers and chrysanthemums as well as many common weeds and wildflowers.
