More proof: Tailored herbal medicine treatments do not work

27 11 2007

As stated by the authors of a recent systematic review “There is no convincing evidence that individualised herbal medicine is effective in any indication.”. What’s more, there’s a high risk of side effects and the potential for herbs to react badly with other herbs and prescription medicines.

Studies promoting the effectiveness of herbal medicines have been steadily increasing over the past 20 years, say the authors. But most clinical research has involved standard preparations or single herbal extracts rather than the individually tailored treatments favoured by herbal medicine practitioners. This suggests that they have been sponsored by manufacturers, eager to cash in on the growing market for over the counter remedies.

The current findings are based on an analysis of the available comparative clinical research (randomised controlled trials) on individually tailored herbal medicine treatments. But only three studies out of more than 1300 were randomised controlled trials of sufficient quality to draw meaningful conclusions.

Results showed that there were no statistical differences between tailored herbal medicine and placebo in either the knee osteoarthritis study or the cancer treatment study.

Authors advise that herbal medicine, which currently have no basis in science, and others over the counter remedies shouldn’t be confused with phytotherapy, which represents the scientific face of herbalism. Phytotherapy has considerable potential to benefit patients. But over the counter remedies and traditional herbal medicine can harm those who use them. Researches conclude saying that “without these distinctions, we will fail to advance our knowledge of the potential benefits of herbal treatments. More importantly, we will also fail in our foremost duty – to protect the public from treatments that cause them harm”.

European day of healthy food and cooking with children

25 11 2007

I’m a bit late to report this, but better late than never… Last 8th of november was the European day of healthy food and cooking with children, co-organised by the European Commission and the European Chefs’ Association.

This day aims to encourage healthy eating among children, with a view to tackling the rising childhood obesity levels in Europe. EU officials, top chefs and school children came together for demonstrations on how to cook healthy, tasty food and workshops to promote a balanced lifestyle.

With around 22 million overweight or obese children in the EU today, the aim is to instil an interest in children in the food that they eat and to make them aware of the basic principles of good nutrition. Childhood obesity is an extremely worrying problem, with the number of overweight or obese children growing at the rate of 400 000 a year in Europe. Obese children not only suffer from health problems such as diabetes and liver disorders when they are young, but are also likely to be at high risk of heart disease, cancer, hypertension, stroke and depression as they get older.

This website for children demonstrates that eating healthily can be fun. It also provides a European forum for healthy food and cooking with first class healthy recipes and cooking advice. The website is available in 12 languages and includes an interactive cooking game so that children can learn by playing. What a shame catalan is not included among them, it would be a great way to approach 9 million potential viewers.

Whole grain breakfast seems to lower heart failure risk in men

24 10 2007

wholegrain It was already known, from previous studies, that high grain consumption is linked to a lower risk of high blood pressure, coronary heart disease and high blood cholesterol, and lower mortality in general.

A new study published in the Archives of Internal Medicine has shown that the consumption of whole grain cereals for breakfast lower the risk of heart failure in man, compared to those who never or rarely eat whole grains for breakfast.

The authors explain that the lifetime risk for heart failure is about 20% for both men and women at 40 years of age. Researchers looked at the link between breakfast cereal consumption and new cases of heart failure among 21,376 males whose average age was 53.7 years. The analysis of data demonstrated that a higher intake of whole grain breakfast cereals is associated with a lower risk of heart failure. They believe this link may be because of the beneficial effects of whole grains on heart failure risk factors, such as heart attack, diabetes, high blood pressure and obesity.

The importance of eating together as a family

17 10 2007

A recent study published in the Journal of the American Dietetic Association has found that eating together as a family during adolescence is associated with lasting positive effects on dietary quality in young adulthood.

The study, conducted in 1,500 students, consisted in a survey to determine the long-term effects of family meals on diet quality, social eating, meal structure and meal frequency.

The researchers found that eating family meals together during adolescence resulted in adults who ate more fruit, dark-green and orange vegetables and key nutrients, and drank less soft drinks. An elevated frequency of family meals as adolescents predicted eating dinner more frequently as adults, placing a higher priority on structured meals and a higher priority on social eating.

This study proves once again the importance of food and nutrition education and the role that professionals in this field, like dietitians, can play encouraging families to share meals as often as practically possible.

Perceiving Food As Healthy Often Encourages Overeating

4 10 2007

A recent study from the Journal of Consumer Research reveals that people usually over-generalize “healthy” claims. This research has shown that consumers choose beverages, side dishes, and desserts containing up to 131% more calories when the main dish is positioned as “healthy”.

People tend to have a black and white view, classifying food simply as good or not good. If we see a fast-food restaurant advertising low-calorie products, we think, ‘It’s OK: I can eat something there and then have a high-calorie dessert,’ when, in fact, many of this products contain more calories than a Big Mac.

The study show us how the result of this calorie underestimation translates in consumers choosing beverages, side dishes, and desserts containing up to 131% more calories when the main course was positioned as “healthy” compared to when it was not. Even though, in the study, the “healthy” main course already contained 50% more calories than the “unhealthy” one.

The authors stated that “These studies help explain why the success of fast-food restaurants serving lower-calorie foods has not led to the expected reduction in total calorie intake and in obesity rates”.

Researchers believe that agencies should encourage people to examine whether the restaurant’s health claims actually apply to the particular food they ordered, eliminating then the “health halo” effects.

People need to learn to think about food not just qualitatively (as in “good food — bad food”) but also quantitatively (as in “how many calories are in this meal?”). But to achieve that, there’s need of more nutritional education, which should be provided by the professionals in this field –dietitians–.

Risk Of Prostate Cancer Lowered By Eating Certain Vegetables

30 09 2007

The risk of prostate cancer may be reduced by consuming more than one serving per week of broccoli, cauliflower, and other cruciferous vegetables, according to a study published in the Journal of the National Cancer Institute.

This research conducted among over 29,000 men has found that men who ate broccoli, cauliflower, cabbage, Brussel sprouts, and turnips were 40 percent less likely to be diagnosed with aggressive prostate cancer compared to men whose diet included very little of these vegetables.

The study found that men who consumed cauliflower more than once a week were 52 percent less likely to be diagnosed with extraprostatic prostate cancer compared to those who ate cauliflower less than once a month. Men who consumed broccoli more than once a week were 45 percent less likely to be diagnosed with aggressive prostate cancer.

Cruciferous vegetables, like broccoli or cabbage, contain numerous powerful anticarcinogens called glucosinolates. The results found in this and previous studies have suggested that a healthy diet should regularly contain servings of this group of vegetables.
