What Are Cruciferous Vegetables?
Cruciferous vegetables are a large and diverse group of edible plants, each proving strong and unique flavors.

This kind of vegetable has risen in popularity recently due to its apparent cancer-fighting properties.

What Are the Health Benefits of Cruciferous Vegetables?
Cruciferous vegetables are good for your health in many ways, and their health benefits are well proven by many authorities. Cruciferous vegetables are low-calorie and rich in folate, vitamins C, E, and K and dietary fiber.
Cancer Prevention
The vegetables also contain glucosinolates which give a unique aroma and flavour. When cooking the vegetables, the glucosinolates break down into indoles and isothiocyanates. According to the animal testing done by the National Cancer Institute of the United States, these compounds can protect cells from DNA damage, inactivate carcinogens, and have antibacterial and anti-viral effects.
Another research from Oregon State University also proved that higher cruciferous vegetable intake effectively mitigates the risk of lung cancer and colon cancer by analyzing the correlation between individuals’ eating habits and cancer risk.
Prevent Cardiovascular Sclerosis
Moreover, as pointed out by the 2018 research from the University of Western Australia, the cardiovascular walls of older adult women, who eat more vegetables, are 0.05mm thinner than those having fewer vegetables. The researchers also found that the thickness of the cardiovascular walls can be 0.8% thinner if you consume 10g of cruciferous vegetables more every day. Compared with other kinds of vegetables, cruciferous vegetables are more effective in preventing cardiovascular sclerosis.
