The merits of vitamin D, besides improving bone health, are becoming more evident. Consider:

• There is mounting evidence that links low levels of vitamin D to an increased risk of type 1 diabetes, muscle and bone pain, and, perhaps more serious, cancers of the breast, colon, prostate, ovaries, esophagus, and lymphatic system.

• If you want to lower your blood pressure, vitamin D may be just what the doctor ordered.

• If you’re trying to reduce your risk of diabetes, or lower your chances of heart attacks, rheumatoid arthritis, or multiple sclerosis, then vitamin D perhaps should be at the front of the line in your daily supplement regimen.

• A 2010 national study found that the likelihood of having depression is higher in people with deficiency in vitamin D compared to people who are sufficient in vitamin D.

Sunlight is the largest single source of vitamin D for most people. But we live in Maine and we don’t make vitamin D in our skin for five months a year — between November and March — and during the summer months we are urged to use sunscreen to protect ourselves from the sun’s rays. So what should we be doing to make sure we have enough vitamin D?

On Wednesday, Sept. 28, from 6:30-8 p.m., Dr. Jeff Sedlack of Waldo County General Hospital, a surgeon, physician, and lifelong resident of “the great white north,” will discuss “Vitamin D, the Sun and Your Health” in the Education Center next to the hospital.

For a number of years, we’ve been told to be aware of the dangers of the sun and to avoid getting sunburns, which can lead to skin cancer, the most common of all cancers.

Want to find out more about Vitamin D and how it affects your health? What to learn how to get Vitamin D from the sun and still protect yourself from skin cancer? And are you interested in getting the benefits from vitamin D, even during the winter months? Do you need to take supplements or are their ways to get more Vitamin D into your diet?

Dr. Sedlack will address these issues, along with many others during his talk, which is free and open to the public.
