Patient discussion about D

Q. Should I give my baby girl vitamin D? I have a 4 month old baby girl. I have been reading that it is advised to give babies vitamin D. Is this true?

A. Yes, it is advised to give babies a vitamin D supplement. Vitamin D deficiency (not having enough) can be prevented by giving babies a daily supplement (drops) of vitamin D.
Babies need vitamin D for healthy growth and development. It helps them build strong, healthy bones and teeth.
Babies who don’t get enough vitamin D are at risk of getting rickets, a disease that affects the way bones grow and develop. Vitamin D can also help prevent certain illnesses in childhood or later in life.

Q. What food are rich with vitamin D? My son is 4 years old and the Doctor said he has vitamin D deficiency and advised me to give him a vitamin D supplement. I don't like the idea of giving him medicine, can't I just give him food which is rich with vitamin D and if so which foods are rich with vitamin D?

A. The best way to get vitamin D, the way that our bodies were designed to get the vast majority of our vitamin D, is from modest sun exposure. Going outside regularly will help your son to generate adequate amounts of vitamin D. Therefore, on top of the medicine the Doctor prescribed, have him go outside in the sun everyday for about 20 minutes. (Keep in mind that there is a concern of sunburn and increased risk of skin cancer with too much sun exposure, however.)

Q. does vitamin d reduce the risk of breast cancer

A. Vitamin D is not proven to reduce the risk for breast cancer. Its biological effect is helping the calcium that we consume to being built in the bones, thus helping to increase bone mass and help against osteoporosis.
