Spirulina
1. Fuld af næringsstoffer
Spirulina er i familien af enkeltcellede mikrober ofte omtalt som blågrønne alger. Planten producerer energi fra sollys ved fotosyntese.
Spirulina blev spist af astekerne men blev populær da NASA foreslå at de kunne dyrkes i rummet til brug for astronauter.
A standard daily dose of spirulina is 1-3 grams, but doses of up to 10 grams per day have been used effectively.
This tiny alga is packed with nutrients. A single tablespoon (7 grams) of dried spirulina powder contains (2Trusted Source):
- Protein: 4 grams
- Vitamin B1 (thiamine): 11% of the RDA
- Vitamin B2 (riboflavin): 15% of the RDA
- Vitamin B3 (niacin): 4% of the RDA
- Copper: 21% of the RDA
- Iron: 11% of the RDA
- It also contains decent amounts of magnesium, potassium and manganese and small amounts of almost every other nutrient that you need.
In addition, the same amount holds only 20 calories and 1.7 grams of digestible carbs.
Gram for gram, spirulina may be the single most nutritious food on the planet.
A tablespoon (7 grams) of spirulina provides a small amount of fat - around 1 gram - including both omega-6 and omega-3 fatty acids in an approximately 1.5-1.0 ratio.
The quality of the protein in spirulina is considered excellent - comparable to eggs. It gives all the essential amino acids that you need.
It is often claimed that spirulina contains vitamin B12, but this is false. It has pseudovitamin B12, which has not been shown to be effective in humans (3Trusted Source, 4Trusted Source).
Spirulina is a type of blue-green algae that grows in both salt and fresh water. It may be one of the most nutrient-dense foods on earth.
