You wouldn’t be completely wrong in believing kale is good for you, as it’s packed with vitamins A, C, E and K — all essential for even skin tone and skin health. But what many don’t know is that having too much raw kale can lead to hypothyroidism, when the thyroid is underactive and does not make enough of the thyroid hormone. Some of the early symptoms include pale or dry skin, weight gain and brittle hair. The fix? Cook your kale. But you don’t need to go out of your way to get kale. Broccoli, cauliflower, Brussels sprouts and other such cruciferous vegetables have the same nutrients required for good skin health.
