Pig Flu- Influenza (Flu) | Swine Influenza (Flu)

CDC - Influenza (Flu) | Swine Influenza (Flu) If ever there was a time to optimise your immune system it seems now is the time. 28 confirmed cases in New York already.

There were a number of people criticizing factory farming saying they were perfect breeding grounds for new superbugs and it was only a matter of time before a global epidemic was upon us.

We had numerous 'warnings' over the last few years but it seemed even bird flu did little to bang home the threat of the laws of nature and it's determination to restore the equilibrium of diversity of species.

The World Health Organisation has upgraded the phase of pandemic alert to 4 on the Pandemic Flu Phases Chart

Sandwiches 'full of fat, salt and sugar'

Sandwiches 'full of fat, salt and sugar'

The health risks from pre-packaged sandwiches have been featured in several newspapers, with The Times featuring the headline ‘Cheese and pickle sandwich and a heart attack’ and the Daily Mail warning that, ‘Ready-lunch can contain as much [salt] as 12 bags of crisps.’

The newspapers have highlighted the hidden levels of sugar, fat and salt in a number of popular high street sandwiches, saying that one Asda cheese sandwich was found to contain more saturated fat than a Big Mac. Other examples include a Marks and Spencer cheese and chutney sandwich containing over five teaspoons of sugar, and Subway’s six-inch meatball sandwich containing 4.7 grams of salt- more than three-quarters of the recommended daily limit for adults.

London Nutritionist Yvonne says "I was on a panel with Greggs the bakers just a few weeks ago and this subject came up. They at least are committed to reducing salt and hydrogenated fat. I am also concerned how difficult it is to buy wholemeal bread sandwiches. There are 'brown' bread sandwiches but it is often just white flour with some added brown bits. So many nutrients are lost when breadflour is refined it's almost as much of a problem to health as the sugar and salt."

Milk Free Plant Based Calcium Study

healthy bone density calcium research study vegans
Buddhist nuns deliver good news for vegans :

Healthy Bones - Plant Based Calcium study

Further proof and scientific evidence that challenges the popular dietitian's myth that we need cow's milk for calcium to build healthy bones and maintain good bone density.

This research further strengthens the vegans argument that plant based calcium is superior to that in non human milk as plants have supporting nutrients that help with the absorbtion and retention of calcium. This study shows that even with lower intakes of calcium vegans on simple plant based diets are able to have a bone density that equals those eating meat and dairy with higher levels of calcium.

One theory by Danish scientists that explains this is that calcium may be needed to bind to and process excess saturated animal fat and thus is wasted, literally flushed away. Another theory is that calcium is also used to buffer the acidity of animal protein and is passed out in urine - once again just flushed away.

Sydney-based Professor Tuan Nguyen, from the Garvan Institute of Medical Research, collaborated with Dr Ho-Pham Thuc Lan from the Pham Ngoc Thach Medical University to undertake research on bone density in 105 nuns, who live in monasteries and temples in Vietnam’s Ho Chi Minh City.

“We showed that although the vegans studied do indeed have lower protein and calcium intakes, their bone density is virtually identical to that of people who eat a wide variety of foods, including animal protein,” Professor Nguyen said.

The study found the nuns' calcium intake was low, only about 370mg a day, while the recommended level was 1000mg.

Their protein intake was also low - around 35g a day, compared with the non-vegetarian group, which was 65g.

Professor Nguyen said Buddhist nuns were chosen because their faith required them to observe strict vegan diets all their lives.

“We didn’t study vegetarians from the West because many are lacto-vegetarians, so could have considerable calcium in their diets,” he said.

Nutritionist in London Yvonne Bishop-Weston said today "The study shows how a diet rich in vegetables and fruit is likely to have positive effect on bone health. One point to be considered for Western vegans however is that the confounding factor in this report is the vitamin D status. I suspect that the Buddhist nuns are exposed to a healthy amount of sunshine and thus have healthy levels of vitamin D. Vitamin D is a very important synergistic nutrient to maintain good bone health and this may be something that UK vegans with more sedentiary front of computer lifestyles need to account for."

Spit Out Your Energy Drink!

sugary drink? Spit it out!
Why you should spit out your energy drink |

Considering many people go to the gym to manage their weight London Nutritionist Yvonne Bishop-Weston has long held the view that the best thing to do with the sugary drinks on sale in Gyms is to spit them out. Now a scientific study has proven her correct - Spit out those highly processed simple carb rich sugary drinks, drink more water and eat proper food!

Sugars – carbohydrates – in liquids such as energy drinks fire receptors in the mouth which stimulate the brain to increase output, tests found.

The result is an average two per cent boost in exercise performance, with the added bonus of athletes not even feeling as if they are working any harder.

'Much of the benefit from carbohydrate in sports drinks is provided by signaling directly from mouth to brain rather than providing energy for the working muscles,' said physiologist Dr Edward Chambers.

Energy drinks have long been known to boost exercise performance but experts have said the sugar hit alone is not enough to explain the improvement.

Dr Chambers' team found that cyclists who sipped and spat out drinks laced with carbohydrates outperformed those who did the same with drinks laced with artificial sweeteners.

The sugar-drinking group finished a one-hour endurance test two per cent faster.

Previously unidentified receptors in the mouth sent pleasure signals to the brain, which reduced the cyclists' perception of the workload, said Dr Chambers, of Birmingham University, in the Journal of Physiology.

Vitamin D Deficiency- Ill Health Links

Vitamin D Deficiency Linked to Health Conditions in Adolescents:

A study presented at the American Heart Association's 49th Annual Conference on Cardiovascular Disease Epidemiology and Prevention, linked low vitamin D levels with several health conditions in teenagers.

The research team had looked at data of 3,577 adolescents aged 12 to 19 who were part of the National Health and Nutrition Examination Survey (NHANES) carried out from 2001 to 2004."the team found that teens who had the lowest levels of vitamin D had a much higher risk of having certain health conditions. These adolescents had 2.36 times the likelihood of having high blood pressure, 2.54 times the likelihood of high blood sugar, and a staggering 3.99 times the likelihood of having metabolic syndrome, which is a group of risk factors associated with cardiovascular disease and diabetes; these include high blood pressure, heightened levels of triglycerides, decreased levels of 'good' cholesterol, elevated levels of fasting blood glucose, as well as wider waists."

"Not the first and not the last time we'll emphasize the importance of Vitamin D" say Nutritionists London

Mars - National School Nutrition Spin

mars bar nutrition
Mars Snackfood Urges U.S. Congress to Update National School Nutrition Standards - "Mars has worked with the Alliance to encourage the adoption of new school nutrition guidelines that follow the 35-10-35 formula. " --- "which means that snackfoods sold in schools would have no more than 35 percent of calories from fat, 10 percent from saturated fat, and less than 35 percent sugar by weight."

WOW! No more than 35% of calories in the diet from fat and 35% of sugar by weight - that leaves how much for protein and fibre and vegetables ??????? How Noble!

Not sure our Nutritionists would agree that's healthy - about a quarter of your plate left as complex carbs and protein (vegetables?)??

I don't think the Nutritionists will be jumping up and down with glee to support that bit of legislation.

Xeno-Estrogen in Plastic Water Bottles

plastic bottled water bottle estrogen hormones
Hormone-mimics In Plastic Water Bottles Act As Functional Estrogens

Further to the publicity about the dangers of babies formula plastic feeding bottles there is new research about xeno - estrogens in plastic drinking bottles.

Yvonne Bishop-Weston Nutritionist London says "One solution is to get your own water filter - save money, as a small plastic bottle of water can be a rediculous amount of money - use a glass or metal lined thermos flask and avoid the contamination from plastic by drinking from a glass."

More venus are now offering free filtered drinking water - such as Tibits in Heddon Street Piccadilly London.

Martin Wagner and Jörg Oehlmann from the Department of Aquatic Ecotoxicology at the Goethe University in Frankfurt, Germany, claim plastic mineral water bottles contaminate drinking water with estrogenic chemicals.

In an analysis of commercially available mineral waters, the researchers found evidence of estrogenic compounds leaching out of the plastic packaging into the water. Their findings, which show that substances leaching out of plastic food packaging materials act as functional estrogens, are published in Springer’s journal Environmental Science and Pollution Research.

They analyzed 20 brands of mineral water available in Germany – nine bottled in glass, nine bottled in plastic and two bottled in composite packaging (paperboard boxes coated with an inner plastic film).

They detected estrogen contamination in 78% of waters in plastic bottles and both waters bottled in composite packaging showed significant hormonal activity.

“We must have identified just the tip of the iceberg in that plastic packaging may be a major source of xenohormone* contamination of many other edibles. Our findings provide an insight into the potential exposure to endocrine-disrupting chemicals due to unexpected sources of contamination.” said Martin and Jörg
