Is it safe to eat fish?

Fish are considered an important part of a healthy diet. And even though fish may contain low levels of toxins or microplastics, doctors still advise eating fish at least twice a week. This is because the benefits of eating fish exceed the risks. Studies involving hundreds of thousands of people over decades have found that people who eat one or two 3-ounce servings of fish per week have a nearly 40% reduction in death from heart disease—the No. 1 cause of death in the United States and other developed nations.
