Nicotine is the powerful ingredient that makes smoking addictive, while also creating a feeling of relaxation. Nicotine indirectly releases dopamine in the pleasure and activity areas of the brain.

Here are some common everyday foods containing Nicotine:

1. Tomatoes

It may seem a bit surprising, but a typical tomato will have an average nicotine concentration of 7.1 -7.3 ng/g. That means 1 gram of tomato has 7.1 ng of nicotine.

In addition, the results also showed that nicotine concentration can decrease when the tomato is ripe. Tomatoes are plants in the Solanaceae family, which have been found to contain a nicotine alkaloid called tomatine.

2. Potatoes – Nicotine-containing foods

A potato has an average nicotine concentration of 15 ng/g. This concentration is higher in green and sprouted potatoes with reported levels of up to 42.8 ng/g compared to 4.3 ng/g in cooked potatoes.

However, mashed potatoes have a higher nicotine content, up to 52 ng/g.

Potatoes also contain a nicotine alkaloid called solanine. They are relatively concentrated in the skin of potatoes. High concentrations of solanine will actually cause death or some significant health risks.

According to Ayushveda.com, potatoes are also a very good source of nutrients for the body. It contains vitamin B6, vitamin A and potassium 6.

The combination of these nutrients will help prevent cardiovascular disease if potatoes are consumed baked or boiled.

According to the website, people who eat baked or boiled potatoes have a lower risk of heart attack and blood pressure than those who do not consume potatoes.

3. Eggplant is the food with the highest nicotine content

Although high, 10 kg of eggplant is only equal to a small amount of nicotine in cigarettes

Eggplant (eggplant) is a food with a fairly high nicotine concentration, up to 100 ng/g. It is the second highest next to tobacco in the nightshade family, where the alkaloid nicotine is often present.

In addition, this tuber is also a very good source of fiber, vitamin B1, vitamin B6 and potassium.

According to Michael T. Murray's "Encyclopedia of Healing Foods", the health benefits of eggplant are directly related to the presence of a powerful antioxidant called nasunin. Nasunin helps protect the body against free radical damage, helps eliminate excess iron from the body and helps lower cholesterol levels.

4. Chili and Bell Peppers

Common peppers or bell peppers also contain solanine and solanidine, nicotine alkaloids like other nightshade plants. Chili peppers have solanine concentrations ranging from 7.7 to 9.2 mg per 100 gram serving

5. Cauliflower

Surprisingly, a plant that is not part of the nightshade family, also contains nicotine. Research results show that cauliflower contains 16.8 ng/g of nicotine.

Accordingly, cauliflower is another food source of nicotine. Cauliflower is known to be an excellent source of vitamin K, vitamin C, folate and fiber.

Regular consumption of cauliflower will promote a number of health benefits such as protection against certain types of cancer, detoxification of the body and protection against rheumatoid arthritis.
