First, lets start with even more proof, that we need more vitamin D to make sure we retire healthy with independence.

Low vitamin D levels predict nursing home admission
The results of study conducted in the Netherlands, published in the September, 2006 issue of the American Journal of Clinical Nutrition found that having a low level of serum vitamin D is associated with a greater risk of being admitted to a nursing home within six years, and may increase the risk of dying within a similar amount of time.
Marjolein Visser and colleagues at Vrije University in Amsterdam used data from the Longitudinal Aging Study Amsterdam, a prospective study of 3,107 men and women aged 55 to 85 upon enrollment between 1992 and 1993, who were examined after 3, 6 and 9 years of follow up. The current study included 1,260 participants over the age of 65 who participated in the first follow up.
Stored serum samples analyzed for 25-hydroxyvitamin D (25(OH)D) between 1997 and 1998 were classified as deficient (under 25 nanomoles per liter), insufficient, borderline, or normal (greater than or equal to 75 nanomoles per liter). Over the six year period, 138 participants were admitted to nursing homes. Between the beginning of the study and April, 2003, there were 380 deaths.
There were 58 nursing home admissions among participants with deficient levels of vitamin D compared to 5 among those whose vitamin D levels were normal. Adjusted analysis found that vitamin D deficiency increased the risk of nursing home admission by more than three times the risk experienced by those with normal levels. Vitamin D insufficient and borderline patients also experienced greater risk. Additionally, the risk of dying during the designated period was increased by vitamin D deficiency. After adjustment for age, gender, and education, vitamin D deficiency was associated with a 61 percent greater risk of death compared to that of participants whose vitamin levels were normal, however, this risk did not appear to be significant after further adjustment for health, lifestyle, and frailty.
The authors suggest that the greater risk of nursing home admission among individuals with deficient and insufficient vitamin D levels could be due to their increased muscle weakness and risk of falls, as well as a greater risk of osteoporosis. “Lower serum 25(OH)D concentrations in older men and women are associated with a greater risk of future nursing home admission and may be associated with a greater mortality risk,” the authors conclude. “These results could indicate that lower vitamin D concentrations may specifically affect the level of independence in old age.”

Next health experts say we could be the first generation who's kids will die before their parents. This article makes some silly statements, but the part about evolution and what were programed to eat, is right on.

Evolution, not just gluttony, led to obesity pandemic
SYDNEY (Reuters) - Evolution and the environment, not just gluttony, has led to a global obesity pandemic, with an estimated 1.5 billion people overweight -- more than the number of undernourished people -- an obesity conference was told on Monday.

This next article explains that evolution may explain why protein is the most satiating of the macronutrients, since the hunter-gatherer diets contained much more protein than most modern meals.

Virgin olive oil best for heart health

Obesity is already recognized as one of the leading preventable causes of death from heart disease and diabetes but this RNIB report said it was also a key factor in sight loss.

Obesity doubles risk of blindness, says report
LONDON (Reuters) - Britain's increasing number of obese adults and children face twice the risk of losing their sight from a range of degenerative eye conditions, a report from the Royal National Institute of the Blind said on Wednesday.
