To Your Good Health: Milk, fish combination is not harmful

DEAR DR. ROACH: A friend told me that I should not drink milk after eating fish or any seafood. Is there any truth to that? – P.

ANSWER: That’s a new one to me, but I did research on it, and apparently a lot of people have been told that it isn’t healthy, that it can cause white spots (vitiligo) on the skin or that the milk can make the fish toxic. None of these is true.

As long as the fish and the milk are themselves wholesome, the combination of the two does not cause any health issues. Plenty of traditional dishes combine them (for instance, chowders).

DEAR DR. ROACH: In a recent column, you discussed possible vitamin D deficiencies caused by no sun exposure from extreme clothing coverage or not going outside at all. I have been diagnosed with vitamin D deficiency and am taking 2,000 IU daily, per my doctor’s advice. I get a lot of sun exposure, but I use SPF 30 up to SPF 70 sunscreen depending on the amount of exposure I am getting, due to concerns of skin cancer. Is this inhibiting my vitamin D production the same way that covering up completely with clothing does? – J.G.

ANSWER: Sunscreen does reduce the amount of vitamin D that your skin can synthesize. People who are very careful to keep applying sunscreen, as you report, are at higher risk for developing vitamin D deficiency. This is probably why your doctor recommends that you take supplemental vitamin D. The active form of vitamin D (like D-3, cholecalciferol) gives you all you need without any sun exposure, while allowing you to avoid risk of skin cancer.
