We all know that moderation is key and the only correct answer, but how do we know when we have crossed the line of healthy taste, when a certain food does not harm us, but benefits us?!

Many call yellow onion a nutritional power plant of health, as it contains a large amount of antioxidants, containing between 270 and 1187 milligrams of flavonoids ... Data relates to 1 kilogram of yellow onion, while the red one has approximately 10 to 20 percent more vulnerable substances.

But the key question is, what is the upper limit, how much onion can we still eat?!

The answer is not so simple, as it is different for everyone. That's why you need to be most attentive.

1. Smell
When you feel like even your skin smells like onion, you know you went too far about 15 minutes ago, crossed the line of moderation. The solution is to eat onions slowly.

2. Digestion
You may find that onions send you to the toilet. No problem! Some flavonoids have a strong laxative effect. This can also be a sign that you've eaten too much onion.

3. Allergies
Onion can cause allergic reactions in the body, which means you need to stop consuming it immediately. Allergies can manifest as diarrhea, difficulty breathing, itching, hives, nausea... A 2016 study has shown that onion is extremely rich in vitamins C and B, it also has a lot of potassium, which is essential for muscle, kidney, and nerve function. Of course, if there is too much of it, the effects can be opposite to the desired ones.

Today we know that those who consume the upper amount of onion at least twice a month have a 22% lower chance of developing gastrointestinal cancer and a 37% lower chance of developing stomach cancer.

Perhaps these percentages do not seem extreme to you, but do not forget that every food works differently, and data on healing power accumulate.
