(NaturalPath) According to an article published in Food Technology, there are three lesser-known alternative protein sources that aren’t tofu, tempeh and seitan. These are algae-derived proteins, super seaweeds and duckweed.

Algae are nutrient dense with varying amounts of vitamins A, C, E, folate, calcium, iodine, iron, omega-3 fatty acids, carbohydrates, protein and a variety of other nutrients.

In terms of seaweeds, the red variety tends to have the highest protein content. The red species nori has an amino acid profile similar to that of peas or beans, contains a high amount of omega-3 fatty acid and is a good source of vitamin B12.

Duckweed is up to 45 percent protein, which is among the highest protein levels in the plant kingdom. Usually eaten by birds and fish, people in Laos, Thailand, Vietnam, and parts of Africa have been eating various duckweeds for centuries.
