Onion is the vegetable that may make you cry! Onions best feature is their sulphur / sulfur containing compounds which benefit our endocrine, digestive, immune and inflammatory systems.
This compound also fights cancer and detoxification. In fact, eating between 1-7 servings per week may reduce colorectal, laryngeal and ovarian cancer.
Their Quercetin levels may help relieve asthma symptoms and can lower the histamine that your body produces when you have an allergic reaction.
High in chromium, they also assist in regulating blood sugar levels. Crucial for mental health, diabetes and weight loss.
All of these benefits are concentrated in the outer shell, so peel off as little of the edible layers as possible.
Freezed onion really can't be as good as fresh onions but if you use them in soups, stews, or other cooked dishes, though, no-one will ever know the difference.
