3. Tuna sushi
What could be healthier than a serving of tuna sushi? After all, lean fish meat is high in protein and low in fat. But hitting the sushi bar too hard is bad for your health too.
Any type of deep-sea fish contains mercury, a heavy metal that’s toxic to the health. Unfortunately, sushi served in most restaurants contains dangerous levels of this heavy metal. Signs and symptoms of mercury poisoning include high blood pressure, vomiting, extreme fatigue, and hair loss. Tuna is so dangerous that pregnant women and small children are advised against eating it.
