Brown rice protein is another superb plant source of amino acids that provides a good protein alternative for people who are either vegan or lactose intolerant. It is easily digested in comparison to e.g. soy. It also contains less fat, less atherogenic fat and no cholesterol. Protein also reduces the glycaemic index (GI) of a meal which keeps you feeling fuller for longer and reduces the craving for a snack during the day.
