Can Avocados Help You Lose Weight?
Tomatoes contain more alkaloids in the stem and vine than in the fruit. Studies show that as tomatoes mature, the amount of alkaloids in the part that you eat decreases. So, it is unlikely to eat too many alkaloids from tomatoes, especially if you avoid unripe, green tomatoes.
Overall, there is no hard evidence that nightshade vegetables are bad for your health. Some preliminary research shows these vegetables may not be the best for people with certain inflammatory and auto-immune conditions like arthritis or inflammatory bowel disease. However, nightshades don’t cause inflammation directly. They may increase inflammation that is already there.
How do you know if nightshades are bad for you? Experts recommend eliminating them from your diet for a few weeks. Then, reintroduce them and see how you feel. If you feel worse after reintroduction, you may have a sensitivity to nightshades.
Whether or not there is any conclusive evidence about nightshades and inflammation, you should never eat any foods that make you feel bad, or that worsen any conditions you have.
Benefits of Nightshades
Other nutrients in nightshades may be good for your health. They contain antioxidants that protect cells from damage due to stress.
For example, anthocyanin, the antioxidant that gives eggplant its purple color, can reduce the risk of developing cancer, diabetes, and infections.
The antioxidant lycopene, found in tomatoes, may decrease the risk of some types of cancer and heart disease.
Nightshades also contain vitamins and minerals that contribute to good health, like Vitamin A and Vitamin C. Eating one bell pepper, for example, gives you your daily allotment of Vitamin C.
Consuming Nightshades
If you’re concerned about high alkaloid content in nightshade vegetables but still want to benefit from including them in your diet, there are a few things you can try:
In potatoes, the highest concentration of alkaloids is in the skin. One study showed that skinning potatoes before cooking removed up to 70% of the alkaloids.
Baking potatoes in the oven may lower the alkaloid content more than boiling or steaming.
Store potatoes in a dark, cool place to prevent them from producing more alkaloids before you eat them.
