Dr. Manuel Viso, a medical professional and health communicator, shares insights on the consumption of canned tuna. He uses a compelling phrase to denote canned tuna as a healthy food option but cautions against making it a daily staple in one’s diet. While tuna is rich in high-quality proteins, B vitamins, and omega-3 fatty acids, it also has the potential to contain mercury, a heavy metal that accumulates in the body over time and poses health risks.

Viso specifically warns that nearly daily consumption of canned tuna may not be advisable because mercury can deposit in body tissues and adversely affect the nervous system. This accumulation can lead to various cognitive issues, including problems with attention, memory, movement, and even cognitive development, particularly in vulnerable populations such as children. His recommendations focus on moderation and awareness of the potential hazards associated with regular intake of this popular food item.

The doctor also notes that excess mercury consumption can interfere with neurotransmitters like serotonin, which may contribute to mood disorders such as anxiety or depression. Thus, while canned tuna can be a convenient and nutritious addition to one’s diet, Viso emphasizes the need for a balanced approach to its consumption, advocating for alternatives and variety to promote long-term health without the risks of mercury toxicity.
