Essential fatty acids (EFAs) are a necessary part of an individual's healthy diet.New findings indicate that binge-drinking men have lower intakes of n-3 fats, one type of EFA.This low intake exacerbates the already very low EFA levels.Essential fatty acids (EFAs) are just that; an "essential" part of the total fat intake necessary for a healthy human diet. Most EFAs come from plants, but some are animal-sourced. A new study has...
