Top 5 advantages of onions for health
1. Packed with antioxidants
The plant compounds flavonoids, which have anti-inflammatory and antioxidant properties, are abundant in onions. These substances may offer defense against long-term diseases including cancer and diabetes when ingested frequently and in appropriate amounts. In fact, onions are one of the richest sources of flavonoids in our diets and contain over 25 different types.
Sulfur-containing chemicals found in onions have also been shown to have anticancer properties.
2. Could benefit heart health
Quercetin, one of the flavonoids found in onions, is known to have anti-inflammatory and protective actions, and along with other healthy components found in onions, may play a role in the vegetable's heart-friendly features.
According to studies, eating onions may help lessen your risk of heart disease by reducing inflammation, blood pressure, and cholesterol.
3. Could promote bone health
Dietary onions have been linked to increased bone density. This might be as a result of their antioxidant qualities, which lessen oxidative stress and seem to slow bone loss.
According to a study on the impact on peri- and postmenopausal women, eating onions frequently lowers the incidence of hip fracture. Another study on women in their middle years found that consuming onion juice increased bone density and decreased bone loss.
4. Could promote gut health
The non-digestible fiber that is necessary to maintain intestinal health is abundant in onions. Although we are unable to digest prebiotic fiber, the bacteria that reside in our gut can, and they use it as fuel to multiply and make short-chain fatty acids as a byproduct (SCFAs). According to research, these SCFAs are crucial for preserving the gut's health and integrity as well as for boosting our immune and digestion.
5. Preventative
Studies show that onions offer valuable antibacterial qualities against bacteria including Escherichia coli, Pseudomonas aeruginosa, and Staphyloccus aureus, which are used in traditional medicine to treat coughs, colds, and catarrh. Furthermore, the most effective onions seem to be the older, preserved varieties. Because it has the ability to stop the growth of methicillin-resistant Staphylococcus aureus and Helicobacter pylori, it appears quercetin is useful here once more (MRSA).
Are onions suitable for all people?
Even though onion allergies are uncommon, some people can be sensitive to them. As a result, allergic people may develop digestive problems, such as wind and heartburn. Onions include FODMAPs, a type of fiber and carbohydrate that some people's digestive systems find difficult to manage.
How to choose and keep
The skins of globe onions should be dry, smooth, and clean. Avoid onions that have formed seed stems or that exhibit decaying symptoms. Onions should be kept at room temperature, away from strong lighting, and in a place with good ventilation. Yellow onions, which have a more pungent flavor, will keep longer than white onions, which have a sweeter flavor, since the substances that give the harsh flavor are natural preservatives. Potatoes should never be stored with any onions since they will absorb their moisture and ethylene gas, making potatoes more susceptible to spoilage. Cooked onions shouldn't be kept in a metal bowl or other container because doing so will turn them discolored. Onions that have been chopped will lose a lot of flavor if they are frozen.
Tears are created by the substance allyl sulphate, which is created when an onion's burst cells are exposed to the air. Before chopping, refrigerate the onions for around 30 minutes to decrease the activity of the enzyme and lower the formation of this chemical.
