Researchers at the University of Arizona are attempting to weigh the risks and benefits of vitamin D supplementation, a debate that has continued for decades.

“Vitamin D is historically associated with calcium use and strengthening bones, but now it’s showing health benefits that 20 or 30 years ago health professionals dismissed because of lack of information,” says Dr. Ron Watson, University of Arizona Professor in Health Promotion Sciences Division of the Mel and Enid Zuckerman College of Public Health.

Watson was funded for 30 years by the Wallace Research Foundation to study dietary supplements in health promotion. He recently edited and published a handbook of vitamin D in human health.

“The main source of vitamin D is sunlight and we get very little from what we eat,” says Watson.

An outsider to Tucson’s hipster culture and spicy southwest cuisine would tell you that this isn’t much of a town to eat in, unless you wanted Mexican food, which, of course, you often did. Mexican restaurants always have been and always will be a staple and piece of this place, just like the wet August…

Northern Arizona University is located in Flagstaff, Ariz., which is quite a bit different than most of Arizona, particularly Tucson. It’s cold, but it’s beautiful.

It’s not exactly known for its basketball program, though.

The Lumberjacks have been to two NCAA tournaments in their history — once in 1998 when Ben Howland was the head coach, and again in 2000 with Mike Adras. But, NAU lost both games, albeit in close contests (in 1998 by three to Cincinnati, and in 2000 by six to St. John’s).

NAU reached an all-time low in the 2011-12 season when it finished 5-24 and 1-15 in conference. Obviously, it was time for a change at the top of the program — longtime head coach Adras left he program in the midst of the mediocre season. Now, enter Jack Murphy.

Tucson, Ariz.- Restaurants and shops along Fourth Avenue have a particular vibe of art, culture and tradition.

Martin’s Comida Chingona Mexican Restaurant fits this vibe perfectly.

Like many of the restaurants along Fourth Avenue, Martin’s is a small business independently owned by one man…. who is the one and only chef in the restaurant.
