Lidl are currently selling Spirulina (microscopic algae) and (dried) Wheat Grass very cheaply at the moment so I wanted to give you a heads up. I have started adding these superfoods to my smoothies, which is a very easy and delicious way of ingesting them. These natural wonders have been around for centuries. I have visited a Wheat Grass bar in Thailand many a time and there is a reason why these bars are always full of punters. Wheat Grass has an intense nutrient profile. It also has calcium and zinc. Spirulina was part of the Aztec diet and is used as a dietary supplement by athletes today.
