Chocolate

We always knew it was good for us but a new study has found that dark chocolate helps to protect our DNA from oxidative damage.  The researchers commented “the present results are clinically encouraging especially in the field of diet therapy of obesity, pathology related to greater incidence of cardiovascular disease, and cancer”. Unfortunately I don’t think that means we should eat a whole bar a day – more like a couple of squares – and the greater percentage of cocoa in the chocolate the better. Cheering news nonetheless.

Vitamin D and reduction in fracture risk

A study published recently in the British Medical Journal has found that a vitamin-mineral combination of vitamin D and calcium significantly reduced fractures by 8%, and hip fractures by 16%. The study involved almost 70,000 people across Europe and the US and the reduction in risk was for everyone, regardless of age or gender.

Vitamin D and SPF in skin creams

All the huge amount of research coming up about Vitamin D has made me realise how little sun exposure we get these days – especially women. Almost all face creams and foundations contain SPF at some level – usually 15 – so even on normal days we are not exposed to the sun. And when we actually sunbathe even higher factors seem to be de rigeur.

I have recently been diagnosed with coeliac disease and during all the tests they discovered that my Vitamin D levels were 40% of what they should be. As a result I am having to supplement with calcium as well as Vitamin D. There is no question in my mind that I feel better, sleep better, have more energy and less aching joints.

Anyone know of any nice tinted moisturisers which do not contain SPF?

Vitamin D deficiency linked to fat in muscle tissue

Yet more on Vitamin D……………

A study published in the Journal of Clinical Endocrinology and Metabolism has found that low vitamin D levels may be associated with the accumulation of fat in muscle tissue, leading to lower muscle strength.

Vitamin D and cardiometabolic disorders

A systematic research review in the UK has found that high levels of vitamin D among middle-age and elderly populations are associated with a substantial decrease in cardiovascular disease, type 2 diabetes and metabolic syndrome. Furthermore, the decreased risk could even be as high as 43%.

This review adds to a fast growing body of research on the importance of vitamin D and the many health benefits now linked to it.  It is now no longer just important for bone health, but vitamin D deficiency is also linked to a large range of health problems from heart disease and stroke to autoimmune problems and Alzheimer’s Disease.

Vitamin D is not present in many food sources but is primarily manufactured in the skin following contact with sunlight. Compared to our evolutionary ancestors, we now spend very little time in the sun, which has been compounded recently by concerns over skin cancer risk.

In order to ensure optimal daily intake of vitamin D, experts now recommend that supplementation with vitamin D3 (Cholecalciferol) is advisable.

Coffee Intake Linked to Better Prostate Health

Evidence that coffee isn’t always a villain

Researchers have demonstrated that an increased intake of coffee may reduce the risk of lethal and advanced prostate cancers by 60%.

Kathryn Wilson, PhD, from Harvard Medical School and the Harvard School of Public Health said,“Coffee has effects on insulin and glucose metabolism as well as sex hormone levels, all of which play a role in prostate cancer.  It was plausible that there may be an association between coffee and prostate cancer”.

The researchers speculated that whilst caffeine was most likely not the key factor in this association, the actual bioactive components are not known.
Helen Rippon from UK charity, The Prostate Cancer Charity commented independently on the study,
This large-scale study looked at whether coffee drinking might influence the aggressiveness of prostate cancer in men who do develop the disease.  This research does provide a clue that coffee drinking might reduce the likelihood of a man being diagnosed with a more advanced prostate cancer, although there is still more research to do to confirm this and to uncover which component of coffee could be responsible.”
“We would not recommend that men cultivate a heavy coffee drinking habit on the back of this research, not least because a high caffeine intake can cause other health problems.  However, men who already enjoy a regular cup of coffee should be reassured that they do not need to give this up for the sake of their prostate.”

Vitamin D and Depression

We all know that we feel happier in the sunshine and now a new study has confirmed that low levels of Vitamin D are linked to an increased risk of depression. This link is stronger in women than in men.

Blueberries and memory

It’s only a small study but a researchers from the University of Cincinatti have shown that a group of 18 people in their 70s with memory loss who drunk two cups of blueberry juice per day for 12 weeks had improved memory and less depression. They attribute this effect to the blue pigment in blueberries which contains potent antioxidants called anthocyanins.

Bilberries have been traditionally used as a remedy for ailments ranging from diarrhoea and poor night vision to blood sugar control, but improvement of mental function is a promising new finding.

Vitamin D Reduces Colorectal Cancer Risk

Vitamin D Reduces Colorectal Cancer Risk

A new study published in the British Medical Journal, said to be the largest of its kind to date, has found that increased blood levels of vitamin D may reduce the risk of colorectal cancer by as much as 40%.

In the study, researchers used dietary and lifestyle data and collected blood samples from over half a million people participating in the European Prospective Investigation into Cancer Study (EPIC).

The researchers found that blood levels below 50 – 75 nanomoles per litre were associated with an increased risk of colorectal cancer. The association was stronger for colon cancer than rectal cancer.

The researchers also found that,

“Additionally, higher consumption of dietary calcium, but not dietary vitamin D, was found to be associated with a reduced risk of colorectal cancer”.

They concluded,
“However, before any public health recommendations can be made for vitamin D supplementation, new randomised trials are needed to test the hypothesis that increases in circulating 25-(OH)D concentration are effective in reducing colorectal cancer risk without inducing serious adverse events”.

Colorectal cancer accounts for 9% of new cancer cases every year and remains one of the most curable cancers if an early diagnosis is made.
