If you are vegetarian like me, you are constantly looking for good sources of protein. The human body does not digest meat well and it is therefore better for your body to look for alternative sources of protein. Among the natural alternatives, an excellent choice is spirulina with about seventy percent of its dry weight being protein.
A tea-spoon of spirulina (about 7gms) comes with about 4 gms of protein, Vitamins B1, B2, B12, copper and iron. It also has a low carbohydrate content with only 1.7 gms of carbs unlike cottage cheese which many vegetarians eat. In addition to helping you get protein, it acts as an anti-oxidant, helps reduce LDL (bad cholesterol) and reduce blood pressure. It is also known to be a anti-microbial agent especially for candida. Some early studies in Kerala show a positive impact of spirulina on oral cancer.
Spirulina grows in oceans and in salty lakes. Therefore exercising caution while buying it is important as it is can be contaminated. Also, it is not advisable to give this as a supplement to very young children. Finally, it is known to affect drugs that slow blood clotting so if you have been diagnosed with any conditions related to your blood, you should consult your doctor before adding spirulina to your diet.
