What's so super about supergreens?
Not all foods were created equal in terms of nutritional content. But what is it that’s so super about supergreens? Below is a snapshot into the nutritional profiles for six of the key ingredients in the Immunity Boost.
Broccoli is packed with a wide array of nutrients including Vitamin A, C, E, K and folic acid. It is also a source of fibre, protein, iron, potassium, calcium, selenium and magnesium. Just one cup of provides well over the RDA for Vitamin K, which is vital for bone health. It also contains sulforaphane, a compound that has been linked to improved heart health and anti-cancer properties.
There’s a reason why Popeye was addicted to spinach! Spinach is a serious nutritional powerhouse, which trumps its trendier counterpart, Kale, on many levels due to the higher levels of Vitamin K, Vitamin A, protein, Folate, Magnesium, Potassium and Iron. It’s particularly high in Iron, which is vital for making red blood cells (the ones that carry oxygen around the body); and the Vitamin C present in spinach aids iron absorption.
Kale contains more calcium than spinach and double the amount of Vitamin C. It also contains an antioxidant known as alpha-lipoic acid, which has been linked to reduced risk of diabetes and increased insulin sensitivity.
Beetroot is an excellent source of folic acid, which is vital for making red blood cells and the synthesis and repair of DNA. It is also a unique source of phytonutrients called betalains, which have antioxidant and anti-inflammatory properties.
Kiwis are extremely high in Vitamin C, with one fruit containing 53mg (more than is found in the same weight of an orange). Vitamin C is used in the growth and repair of all body tissues, the formation of collagen and the absorption of iron.
Spirulina is a type of cyanobacteria, which can produce energy from sunlight through photosynthesis. A single tablespoon serving (around 7g) contains roughly 4g protein. Whats more, the protein in spirulina includes all essential amino acids, which most plant protein sources do not. Spirulina is also high in antioxidant, pycocyanin, which is responsible for its rich green colour. Antioxidants mop up free radicals and reduce the risk of a number of cancers.
