The role of Vitamin D in common ailments

In part 1, I explored how you could swap lemon balm for caco.  I want to continue this theme of swaping more common foods for exotic super foods: Use Blueberries for Acai Berries Acai berries (pronounced ah-sah-EE), a sort of cross between a grape and a blueberry, look very much like the latter and, oddly, taste a little like a berry dipped in chocolate. They've been used in traditional medicine to treat infections from parasites, ulcers, hemorrhaging, ulcers and diarrhea. Acai berries come from the Amazon region. Besides the berries themselves, the juice and pulp are commonly added to teas, fruit drinks, fruit bars and other products geared toward health and vitality. Nutritionally, these little berries contain high levels of antioxidants, flavonoids and anthocyanins. But as beneficial as acai berries are, their nutritional profile is very comparable to that of blueberries, which are readily available in your local supermarket. Blueberries have truly remarkable benefits for cardiovascular health, as well as for your brain, insulin response and even cancer prevention. Packed with vitamin C, which boosts your immune system and helps collagen to form, they're also loaded with fiber for greater regularity, impacting your heart health, and manganese, a mineral noted for energy conversion and proper bone development.

I said in a previous post that scientists are interested in finding out how massage works.  So if we accept that massage reduces muscle pain, that leaves the question, "How does massage reduce muscle pain?". In 1965, Ronald Melzack and Patrick Wall outlined a scientific theory about psychological influence on pain perception; the ‘gate control theory’.  According to the gate control theory, pain signals are not free to reach the brain as soon as they are generated at the injured tissues or sites. They need to encounter certain ‘neurological gates’ at the spinal cord level and these gates determine whether the pain signals should reach the brain or not. In other words, pain is perceived when the gate gives way to the pain signals and it is less intense or not at all perceived when the gate closes for the signals to pass through. Cutaneous mechano-receptors are stimulated by touch (massage) and transmit information within large never fibres to the spinal cord.  These impulses block the passage of painful stimuli entering the same spinal segment along small, slowly conducting neurons. This theory gives the explanation for why someone finds relief by rubbing or massaging an injured or a painful area. For example, the pain gate theory explains "how"  a child feels better after mum or dad intuitively rub their knee when they have fallen over. In summary massage produces short term pain relief by being a particularly effective trigger for the pain gate process. References Melzack R, & Wall PD (1965). Pain mechanisms: a new theory.

Way back when I first started at Barclays, one of the first clients I treated was returning to work after being signed off with Carpal Tunnel Syndrome.  Which is a common and painful disorder of the wrist, caused by pressure on the median nerve which creates numbness and tingling in the fingers.  At its worse it can lead to loss of grip and permanent numbness in the fingers. Repetitive computer use thought to be one of the causes, but scientific studies have shown contradictory results.   A recent review of the scientific evidence found that frequent computer or mouse use can nearly double the risk of developing the condition.  Repeated tapping, scrolling and swiping on your smartphone or tablet can also lead ot carpal tunnel problems.  If these sort of repeated movements are the cause then improving your posture will help.  But it is also worth ruling out other possible causes such as:

• Diabetes
• Arthritis
• Thyriod Disease
