Great informative book by top expert: 5/5

Dr Holick has been working in the field of vitamin D for over three decades, and the expertise really comes through in this informative book. I bought the title for an article I was writing on vitamin D, and barely needed to refer to any other expert opinion, as the studies etc. were so comprehensive. It will also doubtless become a regular reference on my nutrition degree course.

Great, well structured and very easy to understand, with plenty of technical details thrown in.

Thorough & Practical: 5/5

Of the 8 books on vitamin D I’ve now read, this is now my favourite pick. It’s practical and he has a way with words: “vitamin D deficiency is our most common health challenge globally”, “vitamin D is in a class by itself; its far-reaching effects on the body are aligned with how hormones act to influence metabolic pathways, cellular functions, and the expression of myriad genes”, “in some respected medical circles, sunlight is being described as a ‘wonder drug’”. At 300 pages I also found it thorough and I specially liked the straightforward explanation that sunshine, when it’s strong enough, is always better than supplementing with Vitamin D.

Dr. Holick is a professor of medicine, physiology and biophysics at Boston University Medical Center in the USA who has studied vitamin D for over 30 years and has received awards relating to health research and nutrition. He explains that he lost his teaching position as a Dermatologist in 2004 because he refused to agree with his boss and with the Dermatology profession generally that even the tiniest amount of UV/sunshine is bad for us. Unlike most of the other books, which recommend only vitamin D3, he says that either vitamin D2 or D3 is fine.

Of the other books, “The Vitamin D Revolution” by Soram Khalsa was previously the one I preferred while “Vitamin D Prescription” by Eric Madrid is also good but harder to find and more expensive. “Vitamin D” by Rona and “Power of Vitamin D” by Zaidi, both published in 2010, are both brief but quite good. “The Vitamin D Cure” by James Dowd is not basic, comprehensive or practical. Then there is “Vitamin D” by Michael Merrill which was too brief and simply inadequate. At the other extreme is the comprehensive but somewhat technical “Sunshine and Vitamin D” by Frank Murray – mainly brief compilations of hundreds of studies but no practical guidelines, so not really suitable for the layman who wants to experiment with high-dose vitamin D.

There are more and more books – and a great deal of media fanfare – on the recently discovered almost miraculous properties of vitamin D. It’s also worth noting that over a decade ago several books were already lauding the much-overlooked benefits of sunshine, the best way to get vitamin D, although the further away from the equator, the less effective. Anyone living above the 35th parallel (England runs from the 50th upwards) is highly likely to have a sunshine/vit D deficiency that can also lead to many common symptoms. (Those who react badly to Vitamin D and/or sunshine may have a rare disease called sarcoidosis.)

According to most of the books on vitamin D, the vast majority of us are deficient in vitamin D whereas adequate levels can alleviate chronic pain, stroke, osteoporosis, heart disease, cancer, autoimmune diseases, depression, arthritis, diabetes, gum disease, psoriasis, fibromyalgia, autism and much more. Perhaps it’s just my cynicism from decades of reading endless books singing the praises of so-called miracles such as DMSO, MMS, DHEA, vitamin C, magnesium, iodine, omega 3 EFAs, breathwork, oxygen therapy, hydrogen peroxide, water, thyroid hormone, adrenal hormone, liver cleanses, detoxes, fasts, exercise, neutralising electromagnetic stress, juicing, mangosteen, noni juice, superfoods, organic foods, wholefoods, celiac diets, dairy-free diets, veggie diets, protein diets, carb diets, food combining, acid-alkaline balancing diets, Glycaemic Index diets, high fibre diets, raw food diets, candida/fungus elimination, parasite cleansing – oh dear, the list of my gullibility seems endless.

Yes, I’ve tried all of these; yes, thoroughly and sometimes repeating them in various combinations and on each occasion with enthusiasm and bright-eyed hope but I saw no measurable benefits. “Trick and Treat” by Groves explains in detail just why so many of my efforts were doomed. Nowadays, when I read about health wonders, I wonder how many claims of success are made up or at least tweaked – and I wonder what proportion of actual patients were successful in any way, much less miraculously so, as is always claimed by books touting miraculous benefits.

I was startled to learn in this book that about a third of the population has kidney disease (which never gets diagnosed until too late and allegedly little can be done for it apart from horrible treatments like dialysis) and that about the same number are obese (hello… anyone making a connection here?) and that their bodies may not be able to produce enough activated vitamin D even when taking high-dose supplements: as compared to the non-obese, vitamin D levels rose only 50% as much in the blood levels of the obese when using a tanning bed or getting a dose of 50,000iu of vitamin D. The obese get a lot of blame for what is not actually their fault: studies now show that calcium also plays a key role in reducing obesity (elsewhere I have seen studies showing large weight loss in about 30% of obese women who take both calcium and vitamin D).

Holick recommends activated vitamin D (calcitriol) for those whose bodies have difficulty converting vitamin D into the active form, such as older people or those who have a wheat/gluten intolerance (much more common than realised). However, none of the books are clear enough that many with poor health simply cannot produce enough activated vitamin D in their bodies even when taking high-dose vitamin D.

Based on my personal experience of taking 10,000iu daily of vitamin D3 for 6 months (but Rona’s book mentions Norm Shealy, a physician who has taken 50,000iu per day for 18 months), I’m not convinced that vitamin D supplementation of the non-prescription kind is a panacea, as so many of the books are claiming – and I am not convinced that all these authors got the unanimously fantastic results they allege. While I believe that vitamin D supplementation at 5,000ius daily is beneficial, too many such books have a way of sounding a little overzealous, attributing every malady to whatever deficiency they’re tackling and proposing it as the magic solution across the board.

Great informative book by top expert: 5/5

I received 3 books from Amazon as a recent birthday gift. The first was the latest novel by Andy McNab, who, if you haven’t read him, is an extremely gifted and compelling thriller writer. The second was an interesting read about online poker, and how in years gone by, a technique known as bonus whoring was used by many online players to secure guaranteed payouts.

And then there was the latest book by Michael Holick, the Vitamin D Solution, which completed quite an eclectic selection of reading material. I must say that the Holick book was excellent. Extremely informative, and yet still managing to make what is in my opinion a fairly dry topic seem lively and interesting. Doubtless this stems from Holick’s passion for his subject, which shines through in his written work.

Thoroughly Recommended: 5/5

Quit Smoking If You Suffer From Vitamin D Deficiency

It is no secret that smoking damages your health in a variety of ways. Any doctor would recommend that you take whatever steps are necessary to quit smoking. There are a number of products available that can help with this, including switching to electronic cigarettes (also known as e-cigarettes or e-cigs) which you can buy cheaply online.

Although other methods exist to help you quit smoking, studies have shown that people who quit using e-cigarettes are more likely to succeed than those who use gum, patches or just willpower alone. This explains why there are now nearly 2 million people using e-cigarettes. If you’ve tried to quit smoking before via another method, e-cigs are still worth trying due to the higher success rate with this method.

Studies suggest that smokers are more likely to suffer from vitamin D deficiency than non smokers. This effect may be more prevalent in mothers and neonates.

If you suffer from vitamin D deficiency and you are a smoker, then cutting down or eliminating your nicotine intake should be your first step.

Sports

Diet is only one element of a healthy and enjoyable life. Sport is a great way to engage in an active lifestyle. Many people enjoy participating in sport and it doesn’t matter whether you play competitively or just for fun, as long as you get involved in one way or another.

If you’ve not traditionally been a sports fan and are struggling for inspiration, there are many books and videos available which give an introduction to a wide variety of sports and explain how you can get involved.

For those people who do enjoy sport already, but confine themselves to watching or betting on sport rather than playing it, consider taking things one step further by joining a local club or society.

That doesn’t mean that you can’t carry on watching sport on Sky or betting at your local bookmaker, it just means that you should consider getting involved personally as well!

A great resource to get started is “The Sports Book” by BBC Sports broadcaster Ray Stubbs.

The book covers the rules, teams and history of over 250 of the world’s most popular sports. Whilst it does not act as a betting guide or provide statistics that punters could use, it does server as an excellent source of background information for any would-be participant who is looking to take up sport, or even for prospective armchair fans.

Well I bought this book as a present for a sports mad young lad. I was very reluctant to give it to him. Its really well laid out and easy to read. It looked second hand by the time he got it. Lovely book for any aspiring sports fanatic.

I have recently bought this book and i find it very useful and valuable. As i bought it for photography purposes, in order to understand the rules of the certain sports games, which i am going to photograph, this really is a magic wand. One can get familiar with almost all sports “games”, that exist on our planet. Some will surprise you, as you might not even have a knowledge of such sports events existence.
The only improvement, that could be made, would be adding real photos from the events.

Recreation & Gaming

Recreation and having fun are an often overlooked and yet vital part of a healthy lifestyle. There are many refernces to this online, including here and here. In essence, if you don’t spend a reasonable amount of time doing what you enjoy, you are less likely to be healthy and happy.

So whatever it is you enjoy doing, make some time to do it. Some people like to watch sports, some just like to watch TV or go to the movies. Some enjoy spending time in the pub socializing with friends and others like to study form and bet on horses or football at their local or online bookmakers. Gambling is not something to be afraid of if done in moderation and treated as a recreational activity (this is mainly for fun rather than for profit). Indeed, online betting is listed among the top 10 recreational activities for males in the UK. You can find information about online betting, bookmakers and free bets here, plus previews of forthcoming events. Your choice of hobby keeps you relaxed and happy, and means you will have more energy to do the other things in your life.

Playing games is also important. It improves mental dexterity and reasoning, and can also improve hand-eye co-ordination. It is now possible to play games on the move using tablets and mobile devices, so spending half an hour playing a puzzle or skill game does not even need to eat into your everyday routine, it can be done while commuting or in a lunch hour.
