Do you need nutritional supplements?
Vitamins are good for you, but relying on nutritional supplements can actually be bad for your health. The Expert studies have shown that high doses of vitamin supplements including iron, magnesium and vitamin B6 raise the death rate of older women, while taking vitamin E canincrease men’s risk of prostate cancer.
If you are advised that you need to supplement your diet with vitamin tablets you should take a compound i.e. the vitamin B complex rather than B6 on its own, except when medical advice is given. While certain people may be required to take vitamins (those with low levels of vitamin D, for example, or vegans who may be deficient in vitamin B12), for most people a better approach is to opt for a varied diet full of fish, meat, fruit and vegetables which will give you all the nutrients you need
Five portions of fruit and vegetables a day, The Myth.
In the UK you are advised that it is important to eat at least 5 portions of fruit and vegetables a day, in the US up to 9, with the Greek and Germans having a Pyramid with fruit on the bottom level and junk food on the top. There is no scientific evidence for 5 or 7 or 9, it is just a very, very successful advertising campaign organised by interested parties (famers, transport, etc.) and taken up by organisations such as the Kidney Cancer Association and the WHO (World Health Organisation).
Drinking too much water
We are all familiar with the advice to drink two litres of water a day, recent research has shown that there is little scientific evidence to supp this recommendation and that drinking excessive amounts of water can actually be dangerous by lowering the concentration of salt in your blood and causing a swelling of the brain. Sensible drinking of fluids is advisable whether it is water or other liquids. Remember that alcohol and caffeine can cause de-hydration which is the opposite effect of what you want.
Check For Heart Problems
For years the problem of diagnosing a potential future heart attack in women has gone undiagnosed, now, a new test which locates the protein “troponin” in the blood after it has seeped from a damaged heart muscle after a heart attack is available.
Cardiovascular scientists at the University of Edinburgh discovered that the tell tale signs of a past heart attack were less visible in women than men by almost 50%. While the new test helps diagnose the past event in women it makes no difference to men.
Bowel Cancer Screening Tests
Dr Katie Robb from the University of Glasgow said: “The overwhelmingly positive response in our study suggests that people who are invited to have the new test from March this year are likely to have a similarly favorable experience.”
The test will become part of a UK wide screening for all people over 55 following the initial trials in which 98% of patients stated they were pleased to have had the inspection which involves a camera called a flexible Sigmidoscope being inserted into the bowel allowing doctors to remove polyps and growths before they become cancerous. The screening was monitored by Cancer Research UK.
