Hemp seed
What it is
Hemp seed is used as a food. This entry refers to hulled seeds, often called hemp hearts, and not to hemp oil, a concentrated protein powder or an extract.
What it does
The hulled-seed reference contains 31.6 g of protein, 700 mg of magnesium and 8.68 g of alpha-linolenic acid, or ALA, per 100 g. ALA is an essential omega-3 fat.
Research context and ingredient forms
The body converts ALA to EPA and DHA only to a limited extent. The ALA amount therefore should not be treated as an equivalent amount of the long-chain omega-3s in fish or algal oil.
Using this information
Use the weight of hulled seeds when scaling the table. Check the separate label for a hemp protein powder because removing oil and changing the fiber fraction changes its composition.
