Witness the fact that UK national statistics show the average person will live the last 10 years of their life in ill health and some level of dependency. We […]
Big city air pollution is a killer, so defend yourself If you work in a city, you don’t need to be told that air pollution is bad for your eyes – but it is also one of the world’s biggest killers. Air pollution causes more than 5 million premature deaths a year worldwide, an estimated 40,000 […]
Healthier longer with better dietary choices We are living longer – but we are NOT living healthier longer. In fact, the average person will live their last 12 years in poor health and at some level of disability and dependency (UK Office of National Statistics). [See see data here.] Who wouldn’t want to avoid that? […]
Why NO is a big YES NO – Nitric Oxide – is a vital chemical messenger which relaxes otherwise constricted and stiff blood vessels, increasing both oxygen and blood flow. So it’s vital for reducing blood pressure and therefore heart health. Improved blood and oxygen flow is also critical for better brain function as the […]
Nutrients which reduce chronic inflammation The biggest single risk to your long term health is what’s called ‘chronic sub-clinical inflammation’. It’s a continuous, damaging level of inflammation of body tissues that tends to build up as we age, but is normally not noticeable. So it’s an insidious, but major threat. How major? VERY major! “Inflammation […]
Cancer is the result of DNA mutations These mutations (mistakes) initiate cancer because even a tiny error in DNA can make cells multiply out of control. When a cell divides, it copies its DNA, so that each new cell has its own version of your genetic material. But each time this copying occurs, it creates […]
10-a-day? Here is a more realistic answer If you are at all health conscious, you already knew that eating fruits and vegetables reduced the risk of disease. And that 5 a day was the official target. Now researchers at from Imperial College London have conducted a meta-survey – a summary of 95 existing studies involving […]
Autism* linked to Vitamin D deficiency *and other brain development issues 30 years ago the rate of autism was no more than 1 child in 2,500. Today it is 1 in 100 according to the UK National Autistic Society. It may even be as high as 1 in 68 in the USA, according to the […]
SAD Seasonal Affective Disorder I’m looking out of the window and it’s a grey, cold, overcast day. Just the sort of day that encourages Seasonal Affective Disorder or SAD. SAD is associated with a lack of energy and depression. In some 8% of people it’s serious enough to need treatment, but in some degree it […]

The following 10 point plan will not only lower your blood pressure and help you meet the guidelines, but the exact same plan will […]
Why you need a supplement even if you eat healthily The short answer is that there is a big difference between adequate nutrition and optimum nutrition. Most of the food we eat will adequately support life. But it does not necessarily sustain ideal health. Witness the latest alarming data (2015) from the UK’s Office for […]
Read labels carefully I’ve got two top-selling “daily” multi-nutrient nutritional supplements in front of me. BRAND A One announces: ‘Lutein helps maintain healthy eyes’. That’s true, it does. And it’s a “health claim” permitted to be reproduced on a food label. But when I check the level, it says: Lutein: 250 µg Now µg stands […]
Lose 14lbs/6kg by drinking 2 extra glasses of water a day The simple act of drinking more water is associated with reduced intakes of sugar, sodium (salt) and saturated fat – and easier weight control. A study, published in the Journal of Human Nutrition and Dietetics, showed that people who increased their consumption of plain water […]
Everything I need to know, I learned from Noah’s Ark! As this is the Season of Goodwill and shortly the start of a New Year, I thought I would be a little less serious this week! A friend of mine sent me this the other day. I thought it was a good life philosophy! So […]
This Times (UK) headline on November 30th 2016 is a stark warning. According to the Office for National Statistics, men can now expect 16 years of poor health in their life – and women as many as 19 years. I believe that just living longer is not most people’s real aim. What we seek is […]
Food Synergy is where two or more foods combine to give a health boost greater than if the foods were eaten separately. For example a perfect combination is Salmon + Turmeric + Black pepper. Turmeric + Salmon + Black Pepper Curcumin, the active ingredient in turmeric, has many benefits that include being a powerful anti-inflammatory. […]
I compiled these thoughts for my own family, because life today is not easy for the younger generation. (And never really was!) I research and write on nutrition and health. The following collection of wise words is possibly the best nutrition of all: food for the mind. Take a break and be refreshed! Put your […]
Arthritis is portrayed as a rather simple disease. In fact there are several interlinked causes of arthritis. Once you understand them better, you’ll understand why some food supplements fail and why effective treatment and relief is really possible. It’s not age! The chances of suffering with osteoarthritis may increase with age, but it is clearly […]
You are almost certainly not getting enough vitamin D, according to the latest medical evidence. Along with other health researchers in the field, I am concerned that most people have far too little vitamin D for their best health – especially in the winter.
