Vitamin Sunshine

There is much contraversy over Vitamin D and if sunshine alone is adequate to supply the amounts we need. Are you deficient in the Sunshine Vitamin? Unless you are a lifeguard or work outside you are probably not getting enough Vitamin D. Vitamin D insufficiency is common among Americans overall but more prevalent among African Americans. A recent review of the literature suggests that vitamin D insufficiency is a key contributor to cancer survival disparities that exist between African Americans and white Americans (darker skin is less efficient at producing vitamin D in response to UV rays).1 A striking part of this literature review is the comprehensive summary of the existing data on vitamin D status and cancer survival: the authors present a long list of studies reporting that vitamin D adequacy is associated with reduced risk of death in all cancers combined, breast, colorectal, lung, and prostate cancer, leukemia and lymphomas.1

A protective effect of vitamin D against cancers was first proposed in 1980, based on an earlier observation that colon cancer mortality was the highest in geographical areas exposed to the least amounts of sunlight.2,3 Several more studies of geographical variations in cancers have found the same result: inverse relationships exist between sun exposure and 24 types of cancer, including the most common cancers – those of the breast, colon, rectum, and prostate.4,5

Since 1980, evidence for the involvement of vitamin D in the relationship between sun exposure and decreased cancer risk has progressively accumulated, as associations were found between blood vitamin D levels and reduced risk of cancers.6,7 Further support for the importance of vitamin D in cancer prevention was provided by randomized controlled trials of vitamin D supplementation that showed reduced cancer risk compared to placebo. There have also been many reports that vitamin D receptor gene mutations, which interfere with the normal biological actions of vitamin D, were associated with increased cancer risk.8-10

Additional studies confirmed that vitamin D has growth-inhibitory effects on cells derived from breast, colon, prostate, and skin cancers.11 Vitamin D can block cancer cell growth in a number of ways: Vitamin D alters the expression of genes that regulate inflammation, cell death and cell proliferation, and also interferes with the growth-promoting actions of IGF-1 and other growth factors. Additional anti-cancer effects of vitamin D include enhanced DNA repair and immune defenses, and angiogenesis inhibition.12

Today, over 800 scientific papers have been published on the relationship between vitamin D and cancers. We now have ample evidence that maintaining adequate vitamin D levels is an effective strategy for protection against cancer. (Please see references below drfuhrman.com)

You can get Vitamin D through multivitamins, but I recommend Cod Liver Oil.  Once a standard supplement in traditional European societies, cod liver oil provides fat-soluble vitamins A and D, which found present in the diet of primitives in amounts ten times higher than in modernized diets. Cod liver oil supplements are a must for women and their male partners, to be taken for several months before conception, and for women during pregnancy. Growing children will also benefit greatly from a small daily dose.

Cod liver oil is also rich in eicosapentaenoic acid (EPA) and docasahexaenoic acid (DHA). The body makes these fatty acids from omega-3 linolenic acid. EPA is as an important link in the chain of fatty acids that ultimately results in prostaglandins, localized tissue hormones while DHA is very important for the proper function of the brain and nervous system. Those individuals who have consumed large amounts of polyunsaturated oils, especially partially hydrogenated oils, who are suffering from certain nutrient deficiencies, or who have impaired pancreatic function, such as diabetics, may not be able to produce EPA and DHA and will, therefore, lack important prostaglandins and necessary fats for the brain unless they consume oily fish or take a cod liver oil supplement.

Fruitilicious

There are many benefits to Fruit!!  Many times people are scared away from fruits because they are Carbohydrates and have sugar.  But I'm here to tell you that fruit is nature's perfect package.  Get a quick natural energy boost, wrapped in vitamins and fiber and packaged by nature to be eaten with just a hand and mouth (most of the time).  Yellow fruits such as apricots, cantaloupe, and persimmons are good sources of carotene which converts to vitamin A in the body.  Citrus Fruits such as oranges, grapefruit, lemons, and tangerines along with red and green peppers, and cantaloupe, strawberries, and tomatoes are best sources of Vitamin C.  Besides being high in Vitamin A and C they have many other health saving properties.  Look at the list below for your favorite fruit and enjoy!!!
