Eggplant vegetables or Solanaceae, eggplant, peppers, potatoes and tomatoes are a plant family. (Maybe because some of these plants like to grow in shady places, and some flowers grow at night, so the term “solanum” may have been coined). An online search for “solanum vegetables” can link them to many health problems caused by arthritis, migraines. Naturopaths sometimes advise people with arthritis to avoid using eggplant tails. Patricia Wells, a naturopathic doctor in Calgary, said that natural remedies may mean that people with osteoarthritis can eliminate nighttime symptoms. These vegetables are also excluded from certain diet plans. Dr. Joshi’s overall detoxification-endorsed by Gwyneth Paltrow and Kate Moss-claims that Night Dire is related to poison ivy and is potentially toxic. “But poison ivy is often not in the same plant family,” explained Barry Micallef, an expert in plant biochemistry at the University of Guelph.

Why a bad reputation? Micallef explained that some people may think nightshade vegetables are harmful because they confuse them with the’deadly moth’ or Atrope belladonna, which is an inedible weed and part of the Solanaceae. Historically, the deadly nightmare was related to witchcraft. When ingested in large quantities, it may cause convulsions and even death. But this has nothing to do with these vegetables.

There are many health websites or blogs abroad, which will publish some health-related news from time to time, such as “Goop” and “Dr OZ”. Recently, foreign health websites have spread the saying that nightshade vegetables are harmful to the human body, and “nightshade vegetables” have been added to the blacklist of human health.

Foreign health websites and blogs claim that members of the Solanaceae family, such as tomatoes, capsicums, eggplants and potatoes, generally secrete certain toxins to prevent being eaten. , This toxin is harmful to human health.

This claim is derived from a poisonous berry-nightshade, which also belongs to the nightshade family. Nevertheless, this does not mean that all plants in this large family are poisonous. Nutrient-rich Solanaceae plants are the basis for some of the healthiest diets on the planet, such as the Mediterranean diet.

What is lectin?

Some people think that the “toxin” in solanaceous vegetables is a compound called lectins. Lectin belongs to protein and is the main component of meat. But the lectins of Solanaceae plants are slightly different from the proteins in meat because they have sugar attached, which means they can hold cells together. Therefore, those who believe that lectins are harmful feel that it can cause potential damage and pain, such as arthritis. However, simple cooking can decompose these lectins.

Another key point is that the lectin content in plants varies. Some plants contain a lot of lectins (such as kidney beans) and must be cooked before they can be eaten; foods with low lectin content (such as tomatoes and peppers) can be eaten raw.

Do plants produce lectins so they don’t get eaten?

Some people think that the reason plants make lectins is to prevent them from being eaten, so they must cause a certain amount of harm to achieve this goal. They claim that lectins can cause inflammation and worsen arthritis. But in the latest research, there is almost no evidence to prove this.

It is still unclear whether plants produce certain substances that cause harm to the human body. But more and more evidence shows that many compounds in plants have beneficial effects. Polyphenols are found in a variety of fruits and vegetables. They are a kind of bitter chemicals that can prevent plants from being eaten. Studies have shown that polyphenols can reduce the risk of heart disease and stroke, and may even reduce the risk of dementia.

Although lectins have no obvious benefits, and there are some theoretical hazards, these naturally occurring chemicals are easily destroyed after cooking. Therefore, lectins are not a problem. “Solanum vegetables” are rich in vitamins, minerals and polyphenols, and have a lot of fiber, which have great benefits to human health.

Are the recommendations of health websites good?

The favorite of health websites and supporters of “superfoods” is goji berry. But surprisingly, wolfberry also belongs to the nightshade.

Wolfberry pulp can treat dry skin, prolong life, and even improve libido. And wolfberry occupies an important position in traditional Chinese medicine treatment. It is rich in vitamins A and C and has high nutritional value. However, there is currently no evidence that it has health benefits over other types of berries.

Don’t worry too much about famous bloggers or TV doctors telling you to eat or not to eat certain fruits or vegetables. Try to eat different kinds of fruits and vegetables every day to maximize the intake of various healthy substances, and ensure that they are properly stored and washed before eating, and you can enjoy it.
