Changing the diet of pigs, cows, chickens, etc., to include more omega-3 fatty acids would be a healthy alternative to genetic engineering and wouldn’t require government approval. In particular, the weed purslane is higher in omega-3s than any other vegetable and is also edible by humans, although it is not generally available in markets. In addition to improving the quality of meat, purslane feed could produce healthier butter and eggs. And eggs, unlike fish, are plentiful, cheap, and free of pollutants.
