When it comes to maximising health, I’m a great believer in taking supplements, particularly in the modern world where so much of the food supply is grown in depleted soil, which has resulted in our food having much lower concentrations of essential vitamins and minerals than it did decades ago. For example, a Kushi Institute analysis of nutrient data from 1975 to 1997 found that in 12 fresh vegetables, average levels calcium dropped 27%, 37% for iron, 21% for vitamin, and 30% for vitamin C. Another study concluded that today, we would have to eat eight oranges to gain the same amount of Vitamin A as our grandparents would have got from one.
In this newsletter, particularly given the challenges of the current pandemic, I’d like to look at the benefits of vitamin D. Multiple cross-sectional studies have associated lower levels of vitamin D with increased infection. Recently, a scientific review of 25 randomised controlled trials (British Medical Journal, 2017), involving 11,000 participants from a dozen countries, was reported in Time Magazine as follows: “People who took daily or weekly vitamin D supplements were less likely to report acute respiratory infections, like influenza or the common cold, than those who did not … For people with the most significant vitamin D deficiencies (blood levels below 10 [ng/mL]), taking a supplement cut their risk of respiratory infection in half.”
However, vitamin D’s benefits are much broader than that. In addition to supporting the immune system, it contributes to bone health, helps manage blood sugar levels and can prevent diabetes, facilitates hormone regulation and improves mood, and combats heart disease. In fact, it is so vital to our body that recent discoveries have challenged the decades-old advice on protecting ourselves from the sun. In an article published in the prestigious Journal of Internal Medicine, researchers reported that if you AVOID the sun, it increases your risk of death to the same degree as smoking!
The reason for this finding is that the best way to achieve adequate vitamin D levels is by being out in the sun. Could it be, therefore, that those people who are currently avoiding going outside are actually increasing their chances of becoming ill?
