Solanine, Nightshades, and Food Sensitivities: Digging Up the Truth

Some foods can cause sensitivities or even allergic reactions in certain individuals. One group of foods that has received a lot of attention in recent years are nightshades.

Nightshades are a group of plants that include:

  • potatoes

  • tomatoes

  • eggplants

  • peppers

  • paprika

  • tobacco

    These plants are known to contain a compound called solanine, which can be harmful to some people.

Food sensitivities related to nightshade vegetables are not uncommon and can cause several different symptoms such as:

  • eczema

  • bloating

  • diarrhea

  • constipation

  • runny nose

  • headaches

  • breathing difficulties

What Does Research Say?

A 2020 Study suggested avoiding nightshades in an anti-inflammatory diet since nightshades can increase leaky gut in the intestines affecting the microbiome and causing inflammation related to arthritis.

Another 2020 Study published in the Journal of the American College of Nutrition found that eliminating nightshade plants from the diet may be beneficial for individuals with autoimmune diseases, such as rheumatoid arthritis. The study found that a group of rheumatoid arthritis patients who eliminated nightshade plants from their diet experienced a significant improvement in their symptoms compared to those who continued to consume nightshade plants.

While more research is needed to fully understand the relationship between solanine, nightshades, and food sensitivities, these studies suggest that some individuals may benefit from avoiding nightshade plants or limiting their intake of solanine-containing foods. However, it is important to note that nightshade plants are a good source of vitamins, minerals, and antioxidants, so it is not recommended that they be eliminated from the diet unless a sensitivity or allergy has been diagnosed.
