Eggplant

Eggplants are considered a member of the nightshade family, making it a close relative of tomatoes, potatoes, and peppers. The large, dark purple Italian eggplant is most commonly carried in the grocery stores, but there are many other varieties to explore. Smaller cultivars include the Fairytale eggplant, an heirloom variety with light purple and white stripes, and the round, reddish-purple Indian eggplant. Japanese and Chinese varieties are long and skinny with a tender skin and few seeds.

Fun fact: Often considered a vegetable, Eggplants are technically a fruit because they grow from a flowering plant and contain seeds.

In the Garden

Eggplant grows best in hot weather and is very sensitive to cool temperatures (below 50F). Start seeds indoors in April and transplant in June. Expect about 70 days from transplant to harvest, when the fruits have reached full size with a glossy sheen. Good companion plants include other nightshades, which prefer similar soil and nutrients, as well as bush beans, which help to deter pests. 

In the Kitchen

Eggplant is best stored in a loose bag in a cool place on the counter as storing it in the fridge can cause browning and changes in flavor. The neutral flavor and spongy texture makes it a good substitute for meat. This easy recipe for grilled eggplant is sure to please vegetarians and carnivores alike! 

Nightshade Nutrition

While eggplant is not particularly high in any vitamins or minerals, it is very low in calories and provides a healthy dose of fiber (and potassium.) Use it to compliment other seasonal veggies and bulk up a mixed dish without adding extra calories. 
 

Do nightshades really worsen arthritis? Solanine, a chemical compound found in nightshades, is thought to trigger inflammation in some people, which can worsen symptoms of inflammatory conditions like arthritis. Despite a good deal of anecdotal evidence, there is little scientific research on the subject. Listening to your body is always the best call! If nightshades don’t agree with you, don’t eat them, but if you don’t notice a difference there’s no need to cut these delicious and nutritious veggies out of your diet.
