Tilapia vs. Mahimahi — Health Impact and Nutrition Comparison


Summary
Tilapia is higher in protein, fat, vitamin D, phosphorus, and selenium. It is also lower in sodium and cholesterol.
On the other hand, mahi mahi contains more calcium, potassium, vitamin B3, vitamin A, and fewer calories.
Introduction
Tilapia and mahi mahi are two of the most consumed fishes in the world. In this article, we will compare these foods, focusing on their nutritional composition and health impact and showing their actual differences.
Actual differences
Tilapia (1) is a freshwater fish from the Cichlidae family. This fish is usually widespread in the Nile River and the Middle East. Tilapia has a fishy, mild, and a bit sweet taste. Tilapia has a broader range of cooking methods: it is usually consumed in sealed, poached, steamed, grilled, raw, baked, or smoked forms. You can easily find tilapia in markets, in frozen or fresh form.
Mahi mahi (2), the dolphinfish or dorado fish, is a yellow or bright-green predatory fish primarily found in Hawaii. Mahi mahi has a non-fishy flavor compared to tilapia. It is usually fried with herbs, lemon, and spices. The fish lives in the Gulf of Mexico and the Caribbean Sea. However, it is sold and found worldwide.

Health impact
Cardiovascular health
Tilapia and mahi mahi consumption is connected to lower cardiovascular disease risk (4). This is due to omega-3 and omega-6 fatty acid composition. These two compounds are long-chain essential fatty acids that are not produced in the human organism. Hence we must get them with the food we eat. Research shows that the risk of heart disease increases when there is no balance between omega-6 and omega-3 fatty acid concentrations in the blood flow (5). Mahi mahi boosts omega-3 levels in the bloodstream of those with higher omega-6 levels (6).
Health risks
Mahi mahi is considered a food with moderate quantities of mercury. While this mineral is not harmful to healthy middle-aged persons, it can harm kids, teenagers, and pregnant women. (7). To minimize mercury poisoning, limit your fish intake.
While consuming tilapia, you should consider it is often fed with animal feces and farmed with toxic chemicals and banned techniques. It may contain dioxin, a potential carcinogen (8).
