"Protein Sources to Skip: 14 Foods to Avoid for Optimal Health"

Hot dogs containing nitrates and nitrites have been linked to cancer, farmed salmon may contain pollutants and antibiotics, sweetened yogurts can be high in sugar and low in protein, vegan deli meats can be high in sodium and sugar, and grain-fed red meat is high in saturated fat. Store-bought protein bars can be processed and high in sugar and sodium, cheese is high in saturated fat and sodium, bratwurst is high in fat and saturated fat, and swordfish has high mercury levels. It's important to choose protein sources that are lean, low in additives, and provide essential nutrients without compromising overall health.
