What specific toxicity risk arises from consuming excessive preformed Vitamin A (retinol) from sardines daily?
Answer
Potential bone pain, dizziness, and liver problems due to liver storage
Sardines contain considerable amounts of Vitamin A, which is fat-soluble. Unlike water-soluble vitamins, Vitamin A that is consumed in excess of immediate needs is stored primarily in the liver for future use. If daily consumption of sardines, especially when combined with other fortified foods, leads to a chronic over-intake of this preformed Vitamin A (retinol), the accumulation in the liver can become toxic. This chronic overconsumption can manifest in negative symptoms such as experiencing bone pain, feelings of dizziness, and ultimately, potential liver issues, necessitating careful monitoring of total intake.
