Scientists at the BBSRC Center for Integrated Systems Biology of Ageing and Nutrition (CISBAN) at Newcastle University set out to find why a restricted diet affects cell senescence.

“Our research, which looked at parts of the body that easily show biological signs of aging, suggests that a restricted diet can help to reduce.

The amount of cell senescence occurring and can reduce damage to protective telomeres,” said Chunfang Wang, the lead researcher on this project at CISBAN.

Wayne W. Campbell and doctoral student Minghua Tang found in their study that all of the women who ate the energy-reduced diets successfully lost weight.

But the groups that consumed the higher-protein meat-containing diets also lost bone mineral density. "However.

"We know that poor diet and defective genes can both affect development, but here we have seen the two combine to cause a much greater risk of developing health problems and more severe problems. We are excited by this as it suggests that congenital heart defects may be preventable by measures such as altering maternal diet," he said in a statement about the findings.

Of course, you want to believe these claims and so you may be prepared to spend a significant amount of money purchasing these diet products. Usually, you find these products don’t live up to the claims they make, though, and so you may lose a few pounds while using them, but soon notice your weight creeping back up once you stop.

It is therefore clear that you can’t rely on diet products to get you to lose weight and keep it off. If diet products worked there probably wouldn’t be as many of them, as you would pick one that worked, lose the weight and remain slim.

As it is, however, the diet industry is thriving because everyone is desperate to lose weight and because it is so difficult they will spend ridiculous sums of money on the latest diet shakes, meals and bars that if you eat or drink will result in rapid weight loss.

But the advice clashes with the official NHS guidelines and recommendations from the Royal College of Obstetricians and Gynaecologists which say there is no need for every pregnant women to take the supplement. The mixed signals follow a report in the British Journal of Nutrition which says there is a 'strong case' for a daily dose of vitamin D.

The paper says there is growing evidence linking vitamin D deficiency to health problems for pregnant women and newborn babies.Yet the UK is the only one of 31 European countries that doesn't have a set vitamin D recommendation for women of reproductive age.

The study is the latest to link a sugar-laden diet with higher blood pressure, but it also clearly fingers fructose as a major contributor.

“The data is very consistent with what has been in other papers,” said Michael Chonchol of the University of Colorado Health Sciences Center in Denver.

"Knowing which genes can be modulated by diet in a healthy way can help people select healthy diets," said Maria Isabel Covas, a researcher involved in the work from the Cardiovascular Risk and Nutrition Research Group at the Institut Municipal d'Investigacio Medica in Barcelona, Spain.

"It is also a first step for future nutritional therapies with selected foods," she added. Scientists worked with three groups of healthy volunteers. The first group consumed a traditional Mediterranean diet with virgin olive oil rich in polyphenols. The second group consumed a traditional Mediterranean diet with an olive oil low in polyphenols. The third group followed their habitual diet.

Short term weight loss саn bе more harmful іn thе long rυn due tο toxins whісh аrе released during thе yo-yo diet cycle.Aside frοm a well balanced calorie restricted diet, several different forms οf exercise hаνе bееn shown tο deliver powerful weight loss results.

"These clear and important recommendations from NICE strengthen and endorse the current salt reduction campaign in the Britain," Graham MacGregor, professor of cardiovascular medicine and chairman of campaign group Consensus Action on Salt and Health, was quoted as saying.
