Onions: The unsung hero with healing powers
Polish cuisine cannot do without onions. Countless recipes start with the phrase "sauté the onion." Onions are often also added raw to salads and spreads. While they offer numerous nutritional benefits, they are not suitable for everyone.
Onions are inexpensive, available at every market stall, and essential for many dishes we eat daily. It's hard to imagine our kitchen without them, so we usually buy them in large quantities. This vegetable is among the least contaminated with agricultural chemicals, adding to its advantages.
What properties does the onion have?
Onions are known for their richness in quercetin, an antioxidant that neutralises free radicals, which accelerate ageing. It also helps lower blood pressure and has anti-cancer properties. The characteristic aroma of onions is due to sulphur compounds, which not only help fight bacteria but also lower cholesterol levels.
Another important component in onions is vitamin C, which boosts the body's immunity. This vegetable also contains folic acid, which is extremely important for women planning to become pregnant and those expecting a child, as it prevents fetal defects. Additionally, it positively affects the functioning of the circulatory and nervous systems. Onions also contain iron, necessary for the production of red blood cells, and dietary fibre, which is beneficial for the intestines and helps reduce cholesterol levels.
Onions help during and after infection
Onions are worth remembering during the autumn and winter seasons because they help fight colds and flu. Their components enhance overall immunity, reduce inflammation, and help clear the respiratory tract of excess mucus. At one time, natural onion syrup was found in every home, and many people still use it today.
Onions are a source of fructans, a specific prebiotic fibre that provides good nourishment for gut bacteria. This is especially important after antibiotic treatment. Additionally, onions have a soothing and analgesic effect, and they work well for swelling after insect bites.
Who should not eat onions?
Despite their numerous health benefits, not everyone can consume onions. They should be limited if you have digestive tract issues, especially reflux or irritable bowel syndrome. Onions contain fructans, which can cause digestive problems such as stomach pains, bloating, or indigestion.
Raw and fried onions in fat are the most indigestible. They will be much milder after blanching. It’s worth stewing them with the addition of herbs. A good way to mellow the taste of onions is to lightly boil them before frying.
