A Grain-Based Food
Hominy is made from corn, which is definitely not Paleo due to its status as a grain. Like most grains, it is very high in carbohydrates and low in nutrients. It also contains a fair amount of anti-nutrients in the form of phytic acid (a.k.a. phytates), which bind to minerals and prevent them from being absorbed by the body. Consuming grains high in phytic acid can lead to mineral deficiencies and digestive issues in many people.
Properly Prepared Grains
On the other hand, hominy is an ancient method of preparing corn that helps eliminate many of the anti-nutrients, making the protein and calcium contained in the grains more accessible to our bodies. It’s still not technically Paleo-friendly, but if you’re really craving some carbs, you’d probably be better off with some hominy than pasta or bread.
