Be Wary of Protein Powder

According to a recent study, long-term consumption of BCAA-rich protein powder might lead to imbalances in brain chemicals that negatively affect mood, and, further, lead to overeating, obesity, and even an early death. What’s more, testing done by a nonprofit group showed that some protein powders contain high levels of potentially harmful contaminants, such as heavy metals like lead and cadmium, BPA (used to make plastics), and pesticides. And overdoing protein, which is easy to do with powder and other supplements, is linked to unhealthy cholesterol levels, heart disease, and kidney disease. Ensure you get the nutrition your body needs safely by varying your sources of protein and making sure the majority are whole foods. Focus on heart-healthy lentils, beans, salmon, and nuts, and keep red and processed meat to a serious minimum (if you never eat processed meat again, that’s fine by us!). Be sure the rest of your diet is nourishing, too, with plenty of vegetables and fruit, whole grains, and extra virgin olive oil.
