Nutrition at a Glance!
The James Hardiman Library has recently acquired the second edition of a popular title from the 'At a Glance Series' which is published by Wiley Blackwell :
Located at 612.3 NUT
Nutrition at a Glance (2016) - this publication, edited by Sangita Sharma covers such topics as the relationship between diet, health and disease; as well as assessing the consequences of food choices. It also glances at the public health features of sports nutrition, as well as the impact of genetically modified foods and aspects of food safety.

Obesity Update (1)
Could an unhealthy diet and lack of exercise be making you age faster? Researchers at Mayo Clinic believe there is a link between these modifiable lifestyle factors and the biological processes of aging. In a recent study, researchers demonstrated that a poor diet and lack of exercise accelerated the onset of cellular senescence and, in turn, age-related conditions in mice. Results appear today in Diabetes.
Senescent cells are cells that contribute to diseases and conditions associated with age. Researchers from the Mayo Clinic Robert and Arlene Kogod Center on Aging found that exercise prevents premature senescent cell accumulation and protects against the damaging effects of an unhealthy diet, including deficiencies in physical, heart, and metabolic function, equivalent to diabetes.
"We think at both a biological level and a clinical level, poor nutrition choices and inactive lifestyles do accelerate aging," says Nathan LeBrasseur, Ph.D., director of the Center on Aging's Healthy and Independent Living Program and senior author of the study. "So now we've shown this in very fine detail at a cellular level, and we can see it clinically. And people need to remember that even though you don't have the diagnosis of diabetes or the diagnosis of cardiovascular disease or the diagnosis of Alzheimer's disease today when you're in midlife, the biology underlying those processes is hard at work."
In the study, researchers introduced mice to either a normal, healthy diet or a diet that they termed a "fast food diet" -- one that was high in saturated fat and cholesterol, along with a sugar-sweetened beverage. Mice on the fast food diet showed harmful changes in health parameters, including body weight and composition, increasing their fat mass by nearly 300 per cent over the course of about four months. The fat mass accumulated largely in the midsection surrounding internal organs, an area that is often linked to a number of diseases related to obesity.
While the harmful effects of the fast food diet were clear, researchers found significant health improvements after introducing exercise. Half the mice, including mice on both the healthy and unhealthy diets, were given exercise wheels. Mice that had been exposed to the fast food diet but exercised showed suppression in body weight gain and fat mass accumulation, and were protected against the accumulation of senescent cells. Mice on a normal diet benefited from exercise as well.
"Some of us believe that aging is just something that happens to all of us and it's just a predestined fate, and by the time I turn 65 or 70 or 80, I will have Alzheimer's disease and cardiovascular disease and osteoporosis," says Dr. LeBrasseur. "And this clearly shows the importance of modifiable factors so healthy diet, and even more so, just the importance of regular physical activity. So that doesn't mean that we need to be marathon runners, but we need to find ways to increase our habitual activity levels to stay healthy and prevent processes that drive aging and aging-related diseases."

Govt approves bill requiring calories on menus
The Cabinet has approved proposals requiring food outlets to post the information at the point where the food is ordered, whether at tables or counters.
Drafting legislation is expected to start immediately and should be ready for enactment by next year.
Minister for Health Leo Varadkar said the move is a simple but effective way of encouraging people to choose a healthier option.
"I am very concerned about levels of overweight and obesity in Ireland. Latest figures indicate that nearly two out of every three adults, and one in four children, are overweight or obese.
"This presents real risks for health and well-being and causes a high percentage of many of the chronic diseases like heart disease, cancer and diabetes," Minister Varadkar said.
The proposed laws will require all menus, including boards, leaflets, digital menus or other forms, to display the amount of calories alongside the price in the same font size and colour.

'Diet and Major Renal Outcomes'
NUI Galway’s Dr Andrew Smyth
Dr Smyth presented the initial findings of the study at Kidney Week 2014, the annual meeting of the American Society of Nephrology, which was attended by over 13,000 people. The study, which was called ‘Diet and Major Renal Outcomes: The NIH-AARP Diet and Health Study’, used data from a large US study (National Institutes of Health Diet and Health Study). Dr Martin O'Donnell of NUI Galway was the senior author on the report.
Over 500,000 people aged 50-71, living in the United States, provided medical information and completed a diet questionnaire, which was used to measure how healthy each person's diet was at baseline (using four different scoring systems), as well as calculating each person's intake of sodium and potassium. Using available follow-up data, the researchers explored the association between diet and kidney outcomes, including the need for dialysis or dying with chronic kidney disease. During the study period, almost 5,000 people required dialysis or died with chronic kidney disease.
Using three of the four diet scoring systems, people with the highest scores for diet quality had the lowest risk of kidney outcomes. In these three scoring systems, people scored highly for eating plenty of healthy foods (such as fruits and vegetables) and for eating low amounts of unhealthy foods (e.g. deep fried, fatty or sugary foods). The biggest effects were seen with the scoring systems that focus on the whole diet. The fourth scoring system, which focuses only on healthy foods (Recommended Food Score), was not associated with kidney outcomes. In addition, the researchers found that high sodium intake was associated with an increased risk of kidney outcomes, as was low potassium intake.
