But to determine if it will throw you out of ketosis, we need to look at the carbohydrate content.ġ Dalla Pellegrina C, Perbellini O, Scupoli MT, Tomelleri C, Zanetti C, Zoccatelli G, Fusi M, Peruffo A, Rizzi C, Chignola R. So whole grain rice is not necessarily ideal for weight loss. Studies suggest that rice likewise contains a lectin that resembles WGA ( Kolberg et al. WGA can bind to insulin receptors, increasing insulin resistance and thus promoting weight gain ( Shechter 1983 3 Kamikubo et al. However, in addition to gluten, wheat contains a more aggressive lectin in the bran that is equally damaging to the intestinal wall: Wheat Germ Agglutinin (WGA). In this context, gluten has received the most attention so far. Therefore, lectins hide precisely in seeds and hulls. Plants use these sticky proteins to defend themselves against predators ( Dolan et al. These antinutrients bind pathogens, helping them cross the intestinal wall and reach organs ( Dalla Pellegrina et al. So are we smarter than the Japanese concerning rice? Probably quite the opposite!Ĭleaning the husk and bran also removes plant toxins from the grain, particularly lectins. Since brown whole grain rice does not have the bran removed, it retains more nutrients than its white counterpart.Īccordingly, if brown whole grain rice is healthier than polished white rice, why does ordinary rice still form a staple for 4 billion Asians?Īnd why, then, are Japanese so slim? Have you ever seen Japanese people eating brown whole grain rice? No? Neither have I. Therefore, white rice is fortified with vitamins and minerals to increase its nutritional value on paper. This way, manufacturers can increase shelf life and save money.ĭuring the milling process, nutrients such as fiber, manganese, magnesium, selenium, or phosphorus are removed from the rice. It has been processed and polished to remove the bran and germ of the grain.
