Vitamin D deficiency is increasing worldwide. Ultraviolet rays are supposed to provide humans over 80% of our vitamin D requirement; the rest is received through diet and supplements. In addition to enhancing calcium absorption from the intestine and mineralization of the osteoid tissue, vitamin D has many other physiological effects, including neuromodulation, improving muscle strength and coordination, insulin release, immunity and prevention of infections, and curtailing cancer. Whether the increased incidence of vitamin D deficiency is related to increased incidences of nonskeletal disorders remains to be determined. Serum levels of 25-hydroxyvitamin [25(OH)D] above 30 ng/mL indicate vitamin D sufficiency. An additional 1,000 IU of vitamin D/day is sufficient for most lighter-skinned individuals, whereas an extra 2,000 IU/day is needed by the elderly and dark-skinned individuals to maintain normal 25(OH)D levels. Additional research is needed to clarify the relationship between vitamin D and the nonskeletal systems, nonclassic functions, and targets of vitamin D.

No More correctly stated: Only 10-15 minutes per day, 4-6 times per week is needed for a healthy, young, non-obese, white male, with 25% of skin exposed, while lying down, in the southern part of the US, in middle of the day, in the summer, with direct sun, in a rural area. Longer time or more exposed skin is needed if even one of those is not true.
Do not recall hearing this before. Seems possible

Author has a nice subset of 27+ reasons for vitamin D deficiency
The unstated goal is probably for 20 ng. Suspect more is needed for 30 ng
Do not recall seeing that before
No At worse case D2 actually decreases blood levels
Does not mention reaction to vitamin D when low on Magnesium page 7
Does not mention the important of co-factors in building bone
More than 2000 IU needed for seniors with dark skin, women, obese, living far from equator, avoiding the sun, living in a senior facility, and wearing excessive clothes

In his Colloquium, Professor Wilmalawansa will be talking about the importance of diet, lifestyle and medical choices in promoting our health. Physical inactivity and unhealthy eating are major drivers of disease, death, and escalating healthcare costs. Lifestyle medicine applies lifestyle interventions such as environmental, behavioral, medical, and motivational principles in the treatment and management of chronic disease. Behavior modification is an important part of the management of most chronic diseases, such as diabetes, obesity, hypertension, osteoporosis, heart disease, and some cancers. Such diseases can be treated with lifestyle medicine as effectively as – or even more so – than with medications without the risks and unwanted side effects these can involve.
Hormones influence every cell, organ, and function of the body. They regulate mood, growth, metabolism, tissue function, and sexual and reproductive processes. Sustained elevation of stress-related hormones like glucocorticoids and adrenaline has marked negative effects on human health. Sustained and unmanaged stress adversely affects not only the endocrine functions, but also the nervous system, which can result in depression, hypertension, diabetes, obesity, etc. These can be treated effectively with lifestyle medicine.
A key part of lifestyle medicine is to learn and teach the ability to cope with day-to-day stresses and how to adapt to rapidly changing circumstances. Most human disorders are initiated after maladaptation to stress. Thus, learning and practicing various stress-reducing methods, such as meditation, Tai-chi, yoga, exercises, or relaxation including listening to music or playing a musical instrument, can be helpful in alleviating excess stress. A balanced diet and regular exercise together with relaxation of the mind and the body can turn the negative spiral of mental and physical imbalance and stresses into a positive cycle of optimum health.
