Most of our primordial ancestors has the essential protein concerned about the meat. Ignore vegans and vegetarians so our evolution by refusing any animal products? Are vegans even against our evolution? ...

Finally rehabilitated: saturated fats are harmless!

To this day, the DGE recommends that all German citizens eat less fat, especially less saturated fats (and plenty of carbohydrates) for over 2 years, in order to stay healthy and in particular to protect themselves against obesity and cardiovascular diseases. Most recently, she renewed this advice in her updated “10 Rules” last November - even though it was already clear then that it was outdated and basically wrong. The request to eat less (saturated) fats and, if possible, to replace them with carbohydrates contradicts scientific knowledge - I have pointed this out time and again in my books, lectures and articles.

Fortunately, more and more scientists are now speaking out, such as Malhotra in the British Journal of Medicine last year and now Di Nicolantonio in openheart and Chowdhury in the Annals of Internal Medicine. They all conclude (among other things) that the saturated fat recommendations urgently need to be revised because they misinform the public and can even be harmful to health. Some of the most important arguments from DiNicolantonio's work are given as examples:

Vegetarian: More diseases and less quality of life as a multi-meat eaters

Balanced and varied diet that brings highest quality of life - the first time connection between diet and health in Austria investigated

A representative IFES study states that indicate currently around 10% of the Austrians to be vegetarian or vegan. Thus, a large market for specific food products has developed. A study by the Institute of Social Medicine and Epidemiology at the Medical University of Graz, coordinated by Univ.-Ass.in Mag.a Nathalie Burkert, has dealt with the question of how the shape of the diet affects our health and quality of life. The surprising result is inter alia the subjectively poorer health perception and a generally lower readiness for health care of vegetarians compared with those feeding on mixed diet. Healthy with pure vegetable diet?

Depending on the level of education indicate 17 40% of the year Austrians to be vegetarian or vegan. Statistically located in 15% of Austrian households someone who feeds on pure vegetable or vegetarian. A recent study at the Medical University of Graz, coordinated by Univ.-Ass.in Mag.a Nathalie Burkert, however, shows that purely vegetarian nourishing people have a subjectively poorer health perception and therefore require frequent medical services. This requires a whole has a lower quality of life than is the case with those who feed on a balanced and varied diet. "For Austria are currently no relevant data on the relationship of various diets and health. This relationship was examined for the first time in our study, "says Nathalie Burkert.

Green light for low-carb therapy for obesity

Revised Guideline "Prevention and Treatment of Obesity" the DAG allows therapists future choice

To date, was a low-fat, low carbohydrate diet emphasized as the gold standard for the treatment of obesity. This is about to change, as the present, since June 2013 draft revised guideline on the "Prevention and Treatment of Obesity" promises. The under the auspices of the German Obesity Society (DAG) eV updated guidelines revise accordingly the first time the existing decades prejudices against fats. If the animal fats continue to be considered invariably problematic, the existing principle "makes you fat fat" is invalidated. While the previous guideline only recommends calories to eat and to limit fat intake, are the current draft practical tips for everyday life. These also have an effect on the quality of fat and distinguish between favorable and unfavorable fat foods.

Many dietitians design also promises a small revolution. After numerous studies have confirmed the effectiveness of low-carb diets, the diet is the first time the form is now recognized in a guideline. The decision whether the way to the ideal weight should be low-fat or low-carb is henceforth at the discretion of the therapist. Thus, the treatment strategy may in future individual risk based profile of the patient. In addition, include the exercise and behavioral therapy continue the basic program. The bariatric surgery continues to be the last option for weight loss.

The end of July it was to read in almost all media: Who omits the breakfast, which hurts his heart! For a study of the Harvard School of Public Health, which was published in the prestigious medical journal Circulation 1, had revealed: men who do not eat breakfast, have an increased to 27% risk of suffering a heart attack or dying on cardiac death.

"This observational study is a classic example of the cardinal mistake of nutrition research: correlations are reinterpreted as causalities - that principle meaningless statistical relationships are as cause-effect proof spread," explains Udo Pollmer, scientific director of the European Institute of Food Science and Nutrition (EU .LE eV) - but proved nothing, because even if the numbers would vote: Whether failure breakfast for the increased risk of heart attack is causally responsible or typical, but not recognized causes such as shift work or stress - no one knows it!

The lack of vitamin B12 and folate on the track

Vitamins are for us essential. A deficiency can cause serious consequences with it: In older people about the risk of developing dementia increases when they do not get enough vitamin B12 to be. In pregnant women can too little folic acid, which is also one of the B vitamins and folate in the body develops as their effect, lead to complications. What role do these B vitamins in our bodies, scientists at Saarland University Hospital by Professor Rima Obeid and Susanne Kirsch-Dahmen from the Institute of Clinical Chemistry and Laboratory Medicine. Together with other researchers discuss at a symposium on 12. April Homburg about their importance.

Vitamin B12 is involved in many important processes in our body, such as cell division or the formation of blood. Does Vitamin B12 not in sufficient quantities, it can come on the basis of which to folate deficiency and cause permanent health problems. "Especially the elderly and vegetarians often do not take enough vitamin B12 about their nutrition," says Professor Rima Obeid from the Institute of Clinical Chemistry and Laboratory Medicine at the University Hospital in Homburg. "So increases, for example in the elderly the risk of suffering a stroke or developing dementia, clearly." The scientists of the University Hospital study in their studies, among other diagnostic markers to elucidate deficiency symptoms, treat or prevent any sense.

Is low carb dangerous?

An Apology by Ulrike Gonder

Again, because this thing is boiled up again and again: “Diets: low-carb increases the risk of cardiovascular diseases”, so the message on June 27.6.2012, 40.000 on Spiegel online and in other news services. This will unsettle many people who have successfully lost weight with the help of a low-carbohydrate diet or who have reduced their risk factors for those very cardiovascular diseases. The background to the reports is a Swedish study that claims that almost 5 women have a 2012% higher relative risk of heart attack and stroke if the menu contains little carbohydrates and a lot of protein (Lagiou, P et al .: British Medical Journal 344; 10.1136 doi: 4026 / bmj.eXNUMX). My mustard with it

It concerns with the Schwedinnenstudie an observational study, in which the diet raised a single time and in a questionable carbohydrate protein score was converted. The fat intake was strangely no consideration, making the score also suspect. Because in addition to carbohydrates and protein also play the fats yes an essential role for the cardiovascular health. Furthermore, in reasonable carbohydrate reduced diets suggested to replace part of the carbohydrates by protein AND fat, not least because too much protein LEAN (keyword "rabbit starvation") can cause problems.
