Vitamin B1 (Thiamin) is key in turning food into energy. It has a major role in many processes and organs in our body because of it’s function in metabolism and providing energy throughout the body. Many symptoms and conditions can result from low B Vitamins in the diet. You can find B1 in grains, pork, acorn squash, sunflower seeds and broccoli rabe. It’s important to familiarize ourselves with what nutrients we need to prioritize in our diet to stay ahead of our health management and disease prevention.
