Beneftis of kale
It's very low in calories
At only 43kcal per 118g (one cup) of cooked kale, kale is a great addition to any meal if you're trying to lose weight [1]. It’s quite a bulky vegetable and because of its high fibre and water content, will help you feel fuller for longer.
One serving of kale also contains approximately 10% of our recommended daily intake of magnesium. Magnesium helps our bodies regulate our stress hormone – cortisol. High levels of cortisol can negatively affect our metabolism and cause excess fat around our middle [2].
It's packed full of vitamins
Known for its high levels of vitamin C, A & K, and manganese, this leafy green packs a seriously healthy punch. It’s also a very good source of vitamin B6, fibre, potassium, and copper.
In a cup serving of kale there is:
Vitamina C | 28% IDR (M) <> 23% IDR (H)
Vitamin C is renowned for its immune-boosting properties, helping us fight off colds and other illnesses. It also's been associated with a greater production of collagen and younger-looking skin [3Recommended daily intake of Vitamin C for women is 75mg, while for adult men it’s 90mg [4].
One cup of kale (cooked) contains 21mg of vitamin C [5].
Vitamina A | 25% IDR (M) <> 19% IDR (H)
Vitamin A is important for eye health, the immune system, and reproduction. It also helps organs like your heart, lungs and kidneys function properly [6]. Recommended daily intake of Vitamin A for women is 700mcg, while for adult men it’s 900mcg [7]. One cup of kale (cooked) contains 172mcg of vitamin A [8].
Vitamin K | 400%+ DRI (Women and Men)
Vitamin K is important for blood clotting and bone health. The recommended daily amount for women over 19 years of age is about 90mcg and for men about 120mcg [9Kale contains a very elevated level of this vitamin - around 493mcg per cup [10].
According to WEBMD, an excess of vitamin K can pose a health risk for certain people, such as those taking anticoagulants, as many medications can interfere with the effects of vitamin K [11].
Calcium | 12% DRI (Women and Men)
One portion of kale contains approximately 117mg of calcium [12]. Calcium, as we know, is very important for the strength of bones and teeth, and also contributes to many other important functions of the organism [13]. The DRI of calcium is variable according to age and sex. For adults between 19 and 50 it's approximately 1000mg and for women over 50 it's 1200mg daily [14].
Antioxidants
Kale also has a high amount of antioxidants, like the carotenoids lutein and zeaxanthin, which studies show can help protect us against lung and mouth cancers.15].
It's great for your skin
Kale has been shown to be great for skin care since it contains an abundance of antioxidants which help reduce lines and wrinkles while rejuvenating dull or aging skin [16].
Its high vitamin A content supports the production of healthy sebum, which moisturizes the skin and prevents dryness and flaking. Its high levels of vitamin C help collagen synthesis and counteract free radical damage, which contributes to premature aging [17].
It's good for your digestion
Thanks to its high water and fibre content, la kale o “col rizada” nos ayuda a optimizar nuestra salud digestiva, aliviando el estreñimiento y manteniéndonos regulares. La ingesta diaria recomendada de fibra es de 25 gramos al día para las mujeres y 38 gramos al día para los hombres [18. One serving of kale contains approximately 4.72g of fibre, providing about 18% of the daily intake for women and 12.5% for men [19].
