On the Healthy, Sunny Side of Life Monday, Jul 8 2019 

IMG_2025Sunshine isn’t a guarantee in the Chicago area. Most of the year is overcast. When skies are clear, it’s like Christmas here. Residents are deliriously happy and out and about soaking in that rare commodity which is so good for our emotional and physical well-being.

Recent studies suggest that a substantial percentage of the global population is deficient in vitamin D. We need sun exposure on bare skin for 5-10 minutes 2-3 times per week to obtain enough sunlight to produce the necessary amount of vitamin D, which is difficult to achieve in many areas. The lack of sunshine, in addition to high pollution and the use of sunscreen which interfere or prevent absorption, are the main reasons.

Deficiency can be avoided by consuming eggs, fish (especially herring, mackerel, salmon, trout, swordfish, and tuna), fish liver oil, and chicken in addition to fortified foods such as cereals, dairy products, and orange juice. There also are an array of capsules and pills on the market from which to choose from, although there is a great variation of product quality to be aware of.

Vitamin D is actually not a vitamin. It’s considered a pro-hormone. Unlike vitamins, which are nutrients that cannot be created by the body, vitamin D can be synthesized when sunlight hits our skin. But vitamin D breaks down quickly making it difficult to attain and retain enough of it especially in winter.

Sunlight is vital to our health for many reasons. Without it, we may experience fatigue, an increase in aches and pains, severe bone or muscle pain, stress fractures, and a waddling gait in addition to asthma in children. The vitamin regulates calcium and phosphorus and helps to maintain proper bone structure.

Research suggests that vitamin D supports lung function and may play a role in the prevention of type 1 and 2 diabetes; hypertension; multiple sclerosis; heart disease; colon, prostate, and breast cancers; rickets; osteoporosis and bone fractures; rheumatoid arthritis; and swine flu in addition to treating plaque-type psoriasis. It also helps to reduce depression, anxiety, and fibromyalgia symptoms, as well as improve cognitive function.

The recommended intake of vitamin D is about 400 IU but does vary by age. Senior adults are sometimes advised to take double that amount. However, don’t go overboard with this or any vitamin. Excessive consumption of D, called D hypervitaminosis, can lead to calcification of bones and hardening of blood vessels, kidney, lungs, and heart. The most common symptoms of over intake are headache, nausea, dry mouth, a metallic taste, vomiting, constipation, and diarrhea.

D Is For Disease Prevention Friday, Aug 22 2014 

According to a significant study recently published in the journal, Neurology, older adults severely deficient in vitamin D may be more than twice as likely to develop dementia than those who are not. Participants consisted of a group of 1,658 Americans aged 65 and older in the National Heart Blood and Lung Insittute’s Cardiovascular Health Study.

Alzheimer’s is the 6th leading cause of death in the U.S. Currently there are more than five million Americans living with the disease and this number is expected to soar to more than 13.5 by 2050.

The more deficient in vitamin D, the greater the risk of developing dementia. Still unknown is whether eating foods high in this vitamin or taking supplements can delay or prevent the onset of Alzheimer’s disease and other dementias.

Vitamin D has also been linked to preventing asthma, diabetes, and cancer. My pulmonologist, cardiologist, internist, and family physician have all recommended I take it for various reasons.

Vitamin D may be absorbed from sunshine and supplements. It also is found in eggs and oily fish like salmon and sardines.
