The study, which looked at 2,000 five-year-olds, suggested that eating the same food as mum and dad had a greater impact on a young child’s health than any other factor, including social background and snacking between meals, the Daily Express reported. (ANI)
Making a breakthrough in cell-based therapies, Duke University biomedical engineers have grown three-dimensional human heart muscle that acts just like natural tissue.
This advancement could be important in treating heart attack patients or in serving as a platform for testing new heart disease medicines.
The “heart patch” grown in the laboratory from human cells overcomes two major obstacles facing cell-based therapies – the patch conducts electricity at about the same speed as natural heart cells and it “squeezes” appropriately.
Even short-term food deprivation not only increases overall grocery shopping, but leads shoppers to buy 31 percent more high calorie foods, a new Cornell study has revealed.
People skip meals for all sorts of reasons – dieting, fasting, insane schedules that make you forget to eat, said Aner Tal, PhD, from the Cornell Food and Brand Lab, lead author of the study.
“But it doesn`t matter why you skipped a meal, it can still make your nutritionist cry – making you buy more potato chips and ice-cream and less baby carrots and skim milk,” Tal added.
The World Health Organisation (WHO) has removed India from the list of countries with active endemic wild poliovirus transmission.
In written reply to a question in the Rajya Sabha, Minister of State for Health and Family Welfare Abu Hasem Khan Choudhury said Polio free is certified for WHO regions by the Regional Certification Commission and not for individual country.
An ingredient that naturally occurs in breast milk might be used to prevent premature babies from developing a deadly intestinal condition that currently is largely incurable, a new study has revealed.
The story begins with a baby who is born too early, meaning before 36 weeks gestation, said senior author David Hackam, M.D., Ph.D., Watson Family Professor of Surgery, Pitt School of Medicine, and co-director of the Fetal Diagnosis and Treatment Center at Children`s Hospital.

Washington, May 6 (ANI): Stroke is one of the leading causes of death and adult disability, but quickly recognizing the signs of it and seeking immediate medical care from specialists can minimize the effects of the disease or even save a life, say an expert at Cedars-Sinai Medical Center.
Stroke is no longer a disease only of the elderly. Nearly 20 percent of strokes occur in people younger than age 55, and over the past decade, the average age at stroke occurrence has dropped from 71 to 69.
Washington, May 6 (ANI): Most parents make sure that their children drink milk and eat other calcium-rich foods, as it helps build strong bones.
Now, a new study has suggested that it would be beneficial if they also give their kids salmon, almonds and other foods high in magnesium — another nutrient that may play an important role in bone health.
“Lots of nutrients are key for children to have healthy bones. One of these appears to be magnesium,” said lead author Steven A. Abrams MD, FAAP, professor of pediatrics at Baylor College of Medicine in Houston.
There is a strong connection between the food people eat and their oral health, a recently updated position paper of the Academy of Nutrition and Dietetics has stated.
The Academy`s position paper highlighted that nutrition is an integral component of oral health.
The Academy supports integration of oral health with nutrition services, education and research. Collaboration between dietetics practitioners and oral health care professionals is recommended for oral health promotion and disease prevention and intervention.
Adding the carotenoids lutein and zeaxanthin, the omega-3 fatty acids DHA and EPA, or both to a formulation of antioxidant vitamins and minerals that has shown effectiveness in reducing risk of progression to advanced age-related macular degeneration (AMD) did not further help reduce the risk, a new study has found.
Age-related macular degeneration is the leading cause of blindness in the developed world, according to background information in the article.

Researchers have developed a new mouse model, which answers the question of what actually happens in the body when type 2 diabetes develops and how the body responds to the medication.
Bilal Omar from Lund University in Sweden and one of the researchers behind the study said that the animal models for type 2 diabetes studies that earlier existed have not been optimal as they use young mice.
He said that their idea was to create a model, which resembled the situation in the development of type 2 diabetes in humans.
Scientists have mapped avian influenza (H7N9) risk based on the northwards migratory patterns of birds using environmental and meteorological data – from Zhejiang, Shanghai, and Jiangsu, to Liaoning, Jilin, and Heilongjiang.
The map comprises of bird migration patterns, and adding in estimations of poultry production and consumption, which are used to deduce future risk and to advice on ways to prevent infection.
Doctors have time and again harped on the importance of using a sunscreen to protect one’s skin. For many, however, choosing the right sunscreen is a tough choice, what with scores of products with various SPFs (Sun Protection Factors) flooding store shelves.
Does higher SPF mean better protection? Not so much, say doctors, who warn against being misled by marketing gimmicks.
Washington, May 3 (ANI): In a new study, researchers have demonstrated that grapes are able to reduce heart failure associated with chronic high blood pressure (hypertension) by increasing the activity of several genes responsible for antioxidant defense in the heart tissue.
Grapes are a known natural source of antioxidants and other polyphenols, which researchers believe to be responsible for the beneficial effects observed with grape consumption.
Sydney, May 3 (ANI): Based on a new fitness trend sweeping the UK, the latest running craze is all about one thing – darkness.
