Tuna sandwiches may lead to hair loss, experts warn

A hair transplant surgeon warns that daily consumption of tuna sandwiches may contribute to hair loss due to mercury buildup in the body. Eating one tuna sandwich daily can increase mercury intake significantly above the UK average. The surgeon also cautions against excessive consumption of other fish rich in oil, like salmon and sardines, which may also lead to hair loss. Moderate fish intake, about twice a week, is considered safe. For healthier hair, the surgeon recommends eating eggs and spinach, which provide essential nutrients for hair growth. He emphasizes that diet is just one factor in maintaining hair health, alongside lifestyle choices.
