I think we all know that whole grains are best.
Hopefully, we all know why. If not, quick reminder:
Whole grains are left intact after harvesting. The bran, endosperm and germ are all ground up together to make the ingredients for our bread, cereals and crackers. This is why whole grain foods are often grainier and darker than their refined counterparts.
The refined grains are typically made of just the endosperm. Sure this makes them softer, prettier and longer lasting. But, it also leaves them void of nutrition and often full of filler. More scary stuff here.
