The World Health Organization and Food and Agriculture Organization recommend an LA intake between 2.5 and 9 percent of calories, saying that the higher end of the range reduces risk for heart disease.31 The National Academies also doesn’t recommend a specific ratio of LA to ALA, but rather recommends consuming diets that provide between 5 and 10 percent of calories from LA and 0.6 and 1.2 percent of calories from ALA. Vegan intakes of LA in recent studies have ranged from 5.1 to 9.3 percent of calories, putting them within the recommended range.
