How do you remove lectins?

There are many ways to remove lectins from food. Peeling, cooking, and soaking are all effective methods of reducing the number of lectins in your diet.

How To Remove Lectins From Tomatoes

Way 1- Soaking:

Soaking tomatoes in salt water can reduce the number of lectins they contain.

You can soak tomatoes in a bowl of water with a few tablespoons of salt added. The amount of salt you should use will depend on the size of your tomatoes.

Soak them for at least 5 hours and even overnight in a bowl of water, with enough salt added to make it taste like the ocean. Drain and rinse well before using.

This is probably the easiest way to remove lectins from food because you don’t have to do anything except leave it in water overnight or longer if necessary.

Method 2- Peel and Deseed your tomatoes:

Peeling and deseeding tomatoes removes most of their lectin content, leaving behind a fleshy fruit that is easy to digest.

Just peel off the skin, cut into cubes, and deseed before eating! The seeds contain most of the lectin content.

Make sure you wash your hands thoroughly after handling this part of the tomato — tomato flesh contains saponins which can irritate your skin and cause itching or rashes if you touch it with your hands!

Method 3- Using a Pressure Cooker:

Using a pressure cooker can help remove lectins from tomatoes. Place your tomatoes into a pressure cooker, along with enough water to cover them, then cook for 20 minutes at high pressure.

The heat will break down the cell walls, which allows proteins to leak out and dissolve into the liquid.

Method 4- Ferment the tomatoes:

Fermenting tomatoes will also break down their lectin content, but it takes a lot longer than using a pressure cooker — between 3 days and 3 weeks depending on the variety.

During fermentation, the bacteria convert those lectins from the tomato into other harmless substances. The food also becomes rich in probiotics which is excellent for health.

Just remember fermentation can’t kill all of the lectins from every other food, but for tomatoes, it can reduce the amount of lectin noticeably.

Does Peeling Tomatoes Remove Lectins?

Peeling tomatoes does remove lectins. The lectin content of a tomato is concentrated in the skin and seeds. So when you peel the tomatoes you remove quite a bit of lectin from the fruit.

Cooking Out the Lectins:

Cooking will destroy the lectins in tomatoes, but raw tomato ones may be a problem for very sensitive people. You can reduce the amounts of lectin in raw tomatoes by removing the seeds and peeling off the skin.
