Are boiled or steamed vegetables healthier?

Are boiled or steamed vegetables healthier?

Steaming is a method of cooking food using hot steam. Research shows that steamed vegetables have higher levels of vitamin C, beta-carotene and flavonoid antioxidants than boiled vegetables.

Boiling completely submerges vegetables in water, causing water-soluble nutrients to be lost, reducing some nutrients and phytochemicals like vitamin C and beta-carotene. Steaming vegetables still loses vitamin C, but less than boiling.

Analyzes also show that cooking methods at high temperatures and in water for too long, such as boiling, are the most detrimental to the nutritional content of vegetables. Steaming does not submerge the vegetables in water, so there is less loss of nutrients.

Boiled vegetables are often softer and mushy than steamed vegetables, which are crispier. Steamed vegetables also have bright colors and retain more flavor than boiled vegetables.

But depending on personal preference, some people like the taste and feel of boiled vegetables, and soft boiled vegetables may be easier to eat for people who have problems chewing and swallowing.
