What two nutrients are lost when boiling vegetables?

When boiling vegetables, the two main nutrients lost are Vitamin C and B Vitamins (like folate, thiamin, B6), as they are water-soluble and leach out into the cooking water, though some minerals like potassium can also decrease. These water-soluble vitamins are particularly vulnerable to heat and water, making steaming or microwaving better methods for retention, according to Healthline.
