MEDICAL RESEARCH: Vitamin D Necessary for Preserving Cognitive Function

Editor’s note: Promising research published January 8, 2007 shows that adequate levels of vitamin D in the elderly are important to maintain cognitive function or thinking skills that include use of language, awareness, social skills, math ability, memory, reasoning, judgment, intellect, learning, and imagination. This study is called a retrospective review because the researchers did not actually examine anyone. Instead they reviewed data from records of 32 older adults who had been examined for memory Read More »

Osteoporosis in Celiac Disease and How to Prevent It

osteoporosis celiac disease glutenOsteoporosis, or brittle bones, is a generalized bone disorder involving the slow loss of bone mass throughout the skeleton that results in diminished bone mineral density (BMD). Thinning, fragile bones maintain normal cell appearance but have a rapid turnover so that more bone is taken up and removed than is laid down. The result is bone weakness that predisposes people with osteoporosis to fractures.

Osteopenia refers to the progression of bone tissue loss in the range between normal to osteoporosis.

What are Bones?

Bones are dynamic structures made up of living connective tissue and certain minerals. Connective tissue provides the shape of bones and holds calcium phosphate mineral for hardness and Read More »

MEDICAL RESEARCH: Vitamin D Deficiency is Associated with Insulin Resistance and ß cell Dysfunction

 

Editor’s note:

In the following medical research study, healthy participants were enrolled to examine the effects of vitamin D on insulin production and use in the body. This research shows that:

1) Vitamin D plays an important role in insulin sensitivity in the body, and deficiency of vitamin D hampers production of insulin hormone by beta cells in the pancreas.

2) People with vitamin D deficiency are at risk for developing type 2 diabetes mellitus. Type 2 diabetes mellitus is characterized by lack of insulin sensitivity in body tissues and inadequate production of insulin hormone in the pancreas. Read More »

Understanding Vitamin D Deficiency in Celiac Disease

 

Vitamin D, the sunshine vitamin for strong bones and teeth, turns out to be a multi-tasker! Since its discovery in the early 1920s, this important fat-soluble vitamin was labeled simply as “the antirachitic vitamin” (prevents rickets). Not any more. A major discovery of how it functions as a hormone in the body when converted into its active form by the liver has spurred intense research which is revealing much more about this amazing vitamin.

We now know the active form of vitamin D is essential for the regulation of calcium and phosphorus balance in the body, the absorption of calcium and phosphorus from food in the digestive tract, proper neuromuscular function, normal growth and development and normal bone and tooth formation and maintenance. Recent medical research suggests vitamin D may also provide protection from hypertension, cancer, and several autoimmune diseases. Read More »
