It affects the nervous system: the leaf that can end your life if not cooked properly

Thanks to advances in food safety and health controls, most of the foods we consume pose no health risks . However, this vegetable , which has gained popularity in cooking for its tangy flavor and versatility, contains a toxic substance that, in high concentrations, can have serious consequences: oxalic acid. What is it?

The presence of this substance, especially found in rhubarb leaves, can cause severe gastrointestinal disorders such as vomiting, diarrhea, and stomach pain, as well as affecting the kidneys and central nervous system.

Oxalic acid poisoning is not a myth. An article published by BBC News Mundo reports on various historical and medical reports documenting fatal cases following the accidental consumption of rhubarb leaves. Even during World War I, warnings were issued in the United Kingdom following several deaths linked to its consumption as a food substitute.

According to Medline Plus, some of the direct consequences are:

- Breathing difficulty-Blisters in the mouth-Burning in the mouth and throat

​

Coma (unconsciousness, lack of responsiveness)

What should be taken into account when eating rhubarb?

Nutrition experts specify that rhubarb stalks are safe only if cooked properly, as cooking significantly reduces oxalic acid levels, making them safe for human consumption. However, experts recommend never eating the leaves and ensuring the stalks are properly prepared before including them in any recipe.

This isn't the only common food with hidden risks. A similar situation occurs with green or sprouted potatoes, which can also cause poisoning due to the presence of solanine, a neurotoxin that has caused outbreaks of illness and even deaths.

If consumed in large quantities, this natural toxin can cause gastrointestinal symptoms such as vomiting, diarrhea, and stomach pain, and even produce hallucinations, confusion, and acute neurological symptoms. To reduce the amount of solanine and make them easier to digest, it is important to cook potatoes thoroughly. They should also be stored in a cool, dark place to prevent them from turning green or sprouting.
