Before we get to all the benefits, let me briefly explain what kale is… Kale is a popular vegetable, a member of the cabbage family (Brassica oleracea). It is related to cruciferous vegetables like cabbage, broccoli, cauliflower, collard greens and brussels sprouts. There are many different types of kale. The leaves can be green or purple in color, and have either a smooth or curly shape. The most common type of kale is called curly kale or Scots kale, which has green and curly leaves and a hard, fibrous stem.
A single serving of raw kale (about 67 grams or 2.4 ounces) contains (1):
Vitamin A: 206% of the RDA (from beta-carotene).
Vitamin K: 684% of the RDA.
Vitamin C: 134% of the RDA.
Vitamin B6: 9% of the RDA.
Manganese: 26% of the RDA.
Calcium: 9% of the RDA.
Copper: 10% of the RDA.
Potassium: 9% of the RDA.
Magnesium: 6% of the RDA.
Then it contains 3% or more of the RDA for Vitamin B1 (Thiamin), Vitamin B2 (Riboflavin), Vitamin B3 (Niacin), Iron and Phosphorus.
This is coming with a total of 33 calories, 6 grams of carbs (2 of which are fiber) and 3 grams of protein.
Kale contains very little fat, but a large portion of the fat in it is the omega-3 fatty acid called alpha linolenic acid.
Given the incredibly low calorie content, kale is among the most nutrient dense foods in existence. Eating more kale is a great way to dramatically increase the total nutrient content of your diet.
