Broccoli is a cruciferous vegetable, alongside kale, cauliflower, Brussels sprouts, bok choy, cabbage, collard greens, rutabaga, and turnips.
Broccoli has a reputation as a superfood. It is low in calories but contains a wealth of nutrients and antioxidants that support many aspects of human health.
Broccoli is a rich source of vitamins, minerals, and antioxidants. Antioxidants can help prevent the development of various conditions.
The body produces molecules called free radicals during natural processes such as metabolism, and environmental stresses add to these. Free radicals, or reactive oxygen species, are toxic in large amounts. They can cause cell damage that can lead to cancer and other conditions.
Reducing the risk of cancer
Cruciferous vegetables contain a range of antioxidants, which may help prevent the type of cell damage that leads to cancer.
One of these is sulforaphane, which is a sulfur-containing compound that gives cruciferous vegetables their bitter bite.
Some scientists have suggested that cruciferous vegetables such as broccoli may play a role in “green chemoprevention,” in which people use either the whole plant or extracts from it to help prevent cancer.
Improving bone health
Calcium and collagen work together to make strong bones. Over 99% of the body’s calcium is present in the bones and teeth. The body also needs vitamin C to produce collagen. Both are present in broccoli.
Vitamin K has a role in blood coagulation, but some experts have also suggested that it may help prevent or treat osteoporosis. People with low vitamin K levels may be more likely to experience problems with bone formation. Getting enough vitamin K from the diet may help keep the bones healthy.
Boosting immune health
Vitamin C is an antioxidant that provides a range of benefits.
It supports the immune system and may help prevent cancer, cardiovascular disease (CVD), cataracts, and anemia. In supplement form, it may also help reduce the symptoms of the common cold and shorten the time a cold lasts.
Improving skin health
Vitamin C helps the body produce collagen, which is the main support system for body cells and organs, including the skin. As an antioxidant, vitamin C can also help prevent skin damage, including wrinkling due to aging.
Studies have shown that vitamin C may play a role in preventing or treating skin conditions such as shingles and skin cancer.
