Hemp seed oil comparison with fish..
While EPA & DHA are only found in oily fish, the body can convert ALA to EPA and DHA. The conversion between ALA to EPA is inefficient; even in healthy people it is only two to five percent. However, hemp seed oil contains stearidonic acid (SDA) and if taken directly, the conversion to EPA is much easier.
Companies like Monsanto are taking advantage of this fact and are genetically modifying the soya bean to produce SDA.
Thankfully, hemp is a natural source of SDA so there is no need to consume GM produce to get a plant-based supply of omega-3s. Hemp is a source of the rare omega-6 fatty acid, gamma-linolenic acid (GLA), which has many of the health benefits of EPA.
Hemp seed oil contains LA (omega-6) and ALA (omega-3) in the optimum 3:1 ratio for human health and it has a pleasant nutty taste, although it does need to be kept refrigerated to preserve the quality of the oil.
Omega-3 and 6 fatty acids are important for our health and longevity. If you want to avoid fish for whatever reason, hemp is a fantastic choice.
