Do you understand healthy eating?

Do  you understand healthy eating?     Having recently agreed to review its standards by which it assesses which foods can be described as “healthy”, the United States Food and Drug Administration (FDA) surveyed hundreds of members of the American Society for Nutrition about the health values of 52 different foods. The US regulator also carried out a survey of a representative sample of the American electorate, asking them their opinion on how healthy certain foods were. A healthy difference The results revealed surprising disparities between the views of nutritionists and the general public on healthy eating. Orange juice, American cheese, coconut oil, frozen yoghurt and SlimFast shakes were deemed far healthier by the public than the experts. Granola created the biggest divide: 71% of the public thought it was healthy, compared with just 28% of nutritionists. Several of the foods considered healthier by the public than by experts had something in common: they generally contained a lot of added sugar (something a nutritionist would probably be aware of).

Dental hygiene

Romans had no need for dentists, because of one food they didn´t  eat

Romans had no need for dentists, because of one food they didn´t  eat     Modern dental hygiene would have been quite unnecessary for ancient Romans living in Pompeii, as research has revealed that they had impressively healthy teeth. Scientists appointed by the Archaeological Superintendence of Pompeii have used CAT scans to examine 30 Pompeii inhabitants who were preserved in hardened ash after Mount Vesuvius erupted in AD 79. The group, headed by radiologist Giovanni Babino, released photos of their work on Sept. 29, and revealed in a press conference that the ancient Romans had perfect teeth and “no immediate discernible need for dentists,” according news agency Agenzia Giornalistica Italia. Though Pompeii citizens never used toothbrushes or toothpaste, they had healthy teeth thanks to their low-sugar diet. Massimo Osanna, superintendent of the World Heritage-listed site, said their diet was “balanced and healthy, similar to what we now call the Mediterranean diet,” according to The Telegraph.

NOV- 2016.- Aspartame may prevent, not promote, weight loss by blocking intestinal enzyme's activity

NOV- 2016.- Aspartame may prevent, not promote, weight loss by blocking intestinal enzyme's activity     A team of Massachusetts General Hospital (MGH) investigators has found a possible mechanism explaining why use of the sugar substitute aspartame might not promote weight loss. In their report published online in Applied Physiology, Nutrition and Metabolism, the researchers show how the aspartame breakdown product phenylalanine interferes with the action of an enzyme previously shown to prevent metabolic syndrome - a group of symptoms associated with type 2 diabetes and cardiovascular disease. They also showed that mice receiving aspartame in their drinking water gained more weight and developed other symptoms of metabolic syndrome than animals fed similar diets lacking aspartame.
"Sugar substitutes like aspartame are designed to promote weight loss and decrease the incidence of metabolic syndrome, but a number of clinical and epidemiologic studies have suggested that these products don't work very well and may actually make things worse," says Richard Hodin, MD, of the MGH Department of Surgery, the study's senior author. "We found that aspartame blocks a gut enzyme called intestinal alkaline phosphatase (IAP) that we previously showed can prevent obesity, diabetes and metabolic syndrome; so we think that aspartame might not work because, even as it is substituting for sugar, it blocks the beneficial aspects of IAP." In a 2013 study published in Proceedings of the National Academy of Sciences, Hodin's team found that feeding IAP to mice kept on a high-fat diet could prevent the development of metabolic syndrome and reduce symptoms in animals that already had the condition. Phenylalanine is known to inhibit the action of IAP, and the fact that phenylalanine is produced when aspartame is digested led the researchers to investigate whether its inhibitory properties could explain aspartame's lack of a weight-loss effect.

Brain cell therapy 'promising' for Parkinson's disease

Brain cell therapy 'promising' for Parkinson's disease     Scientists believe they have found a way to treat and perhaps reverse Parkinson's disease, by making replacement cells to mend the damaged brain. They say human brain cells can be coaxed to take over the job of the ones that are destroyed in Parkinson's. Tests in mice with Parkinson-like symptoms showed that the therapy appeared to ease the condition. Many more studies are needed before similar tests can begin in people. Experts say the research published in Nature Biotechnology is hugely promising, although at a very early stage. The scientists still have to check if the treatment is safe, and whether the converted cells, which started out in life as astrocytes, can truly function like the dopamine-producing neurons lost in Parkinson's. read more in Mostrar detalle

Life style molecule

What molecules you leave on your phone reveal about your lifestyle

What molecules you leave on your phone reveal about your lifestyle     We leave behind trace chemicals, molecules and microbes on every object we touch. By sampling the molecules on cell phones, researchers at University of California San Diego School of Medicine and Skaggs School of Pharmacy and Pharmaceutical Sciences were able to construct lifestyle sketches for each phone's owner, including diet, preferred hygiene products, health status and locations visited. This proof-of-concept study, published November 14 by Proceedings of the National Academy of Sciences, could have a number of applications, including criminal profiling, airport screening, medication adherence monitoring, clinical trial participant stratification and environmental exposure studies.

Zika virus

How Zika infects the growing brain. by @harvard

How Zika infects the growing brain. by @harvard     Around the world, hundreds of women infected with the Zika virus have given birth to children suffering from microcephaly or other brain defects, as the virus attacks key cells responsible for generating neurons and building the brain as the embryo develops. Studies have suggested that Zika enters these cells, called neural progenitor cells (NPCs), by grabbing onto a specific protein called AXL on the cell surface. Now, scientists at the Harvard Stem Cell Institute (HSCI) and Novartis have shown that this is not the only route of infection. The scientists demonstrated that Zika infected NPCs even when the cells did not produce the AXL surface receptor protein that is widely thought to be the main vehicle of entry for the virus. “Our finding really recalibrates this field of research because it tells us we still have to go and find out how Zika is getting into these cells,” said Kevin Eggan, principal faculty member at HSCI, professor of stem cell and regenerative biology at Harvard University and co-corresponding author on a research paper in the journal Stem Cell Stem.

Calendula extract: effects on mechanical parameters of human skin.

Calendula extract: effects on mechanical parameters of human skin.     Abstract
The aim of this study was to evaluate the effects of newly formulated topical cream of Calendula officinalis extract on the mechanical parameters of the skin by using the cutometer. The Cutometer 580 MPA is a device that is designed to measure the mechanical properties of the skin in response to the application of negative pressure. This non-invasive method can be useful for objective and quantitative investigation of age related changes in skin, skin elasticity, skin fatigue, skin hydration, and evaluation of the effects of cosmetic and antiaging topical products. Two creams (base and formulation) were prepared for the study. Both the creams were applied to the cheeks of 21 healthy human volunteers for a period of eight weeks. Every individual was asked to come on week 1, 2, 3, 4, 5, 6, 7, and 8 and measurements were taken by using Cutometer MPA 580 every week. Different mechanical parameters of the skin measured by the cutometer were; R0, R1, R2, R5, R6, R7, and R8. These were then evaluated statistically to measure the effects produced by these creams. Using ANOVA, and t-test it was found that R0, and R6 were significant (p <0.05) whereas R1, R2, R5, R7, R8 were insignificant (p > 0.05). The instrumental measurements produced by formulation reflected significant improvements in hydration and firmness of skin. Mostrar detalle
