Fish, a double-edged nutrient treasure
Rich in omega-3, protein and essential nutrients, fish can be a valuable ally for heart health and general well-being. However, not all fish are equal, and some may even be harmful to health. This article looks at seven types of fish to avoid, as well as healthier alternatives and tips for choosing the right fish.
1. Tilapia: omega-6-omega-3 imbalance of concern
Tilapia has an unfavorable omega-6/omega-3 ratio that promotes inflammation and increases the risk of heart disease. Moreover, imported tilapia is often below safety standards, with unacceptable levels of harmful chemicals and antibiotics.
2. King Mackerel: a high level of mercury
Although other types of mackerel are healthy, the king mackerel is to be avoided because of its high mercury content, a toxic metal associated with neurological damage and kidney problems.
3. 3. Orange Hoplostah: a centennial fish loaded with toxins
The roughy orange, which can live up to 150 years, accumulates high levels of mercury and other toxic contaminants. Moreover, this species is overexploited, posing a major problem for marine biodiversity.
4. Spa, shark and tilefish: high levels of mercury
