New website launched to ‘veggycate’ Australians on health benefits of vegetables. December 9, 2013 Sophie Langley A new website aimed at improving Australians’ knowledge of substantiated health benefits of vegetables has been launched. The ‘Veggycation’ website (www.veggycation.com.au) explains the health benefits in a “user-friendly way” for children, teachers, consumers, and the vegetable industry. “Vegetables are a great source of key nutrients, but there is limited knowledge on what these nutrients do in the body,” said Dr Jocelyn Eason from Plant and Food Research and project leader for the Veggycation website. “Veggycation will not only help improve the public’s knowledge base about the health benefits of vegetables, but also help the vegetable industry understand and utilise the new Food Standards (Standard 1.2.7 of the Australia and New Zealand Food Standards Code) that allow specific health claims on nutrient rich foods like vegetables,” she said.

December 4, 2013 Sophie Langley For patients with diabetes, it is better to eat a single large meal than several smaller meals throughout the day, according to a new study from Linkoping University in Sweden. The study, which was published on 27 November 2013 in the open-access journal PLOS ONE, compared the levels of blood glucose, blood lipids and different hormones after patients with type 2 diabetes ate meals with three different macronutrient compositions.
The diets were a low-fat diet, a low-carbohydrate diet and a Mediterranean diet. All three diets were tested in a randomised order by 21 patients. The low-fat diet had a nutrient composition that has traditionally been recommended in the Nordic countries, with about 55 per cent of the total energy from carbohydrates.
The Mediterranean diet was composed of only a cup of black coffee for breakfast, and with all the caloric content accumulated to one large lunch. Fat could help solve part of the diabetes problem, Sydney scientists. November 6, 2013 Sophie Langley A fat recycling system within ‘beta cells’ in the pancreas that determines the amount of insulin the body produces could provide a target for future diabetes therapies, according to research from Sydney scientists. The pancreas is a large organ that wraps around the gut, and produces the exact amount of insulin the body needs when a person eats — except when that person starts to develop diabetes, and insulin production slows down.
The researchers said a small structure inside the beta cell, known as a ‘lysosome’, behaves like an intracellular recycling unit. It breaks down unwanted fats and proteins in such a way that they can be re-used. In a study published in the journal Diabetologia, PhD student Gemma Pearson and Professor Trevor Biden from Sydney’s Garvan Institute of Medical Research showed that when they prevented lysosomes from breaking down fat, beta cells secreted more insulin.
The Garvan Institute of Medical Research was founded in 1963. Eating a big breakfast may help women with fertility problems. October 21, 2013 Sophie Langley Eating a good breakfast can have a positive impact on women with problems of infertility, according to a new study from the Hebrew University of Jerusalem and Tel Aviv University. The researchers said that in recent years, nutrition research has found that weight is affected not only by the level of calorie intake, but also by when the largest amount of calories is consumed. The new research, published in the journal Clinical Science, showed that a big breakfast increased fertility among women who suffered from menstrual irregularities. The study examined whether meal times had an impact on the health of women with menstrual irregularities due to Polycystic Ovary Syndrome (PCOS). PCOS affects between 6 and 10 per cent of women of reproductive age, and disrupts their reproductive abilities. The syndrome creates a resistance to insulin, leading to an increase in male sex hormones (androgens).
Study method A big breakfast may help with fertility problems. Order-now. Vinegar at mealtimes reduces risk factors for type 2 diabetes. October 2, 2013 Sophie Langley Ingesting vinegar with meals reduced fasting blood glucose levels in an immediate and sustained manner in health adults who were at risk for type 2 diabetes, according to a new study from Arizona State University. These effects were noted even though no other changes were made to participants’ diets. The 12-week pilot study, published on 4 August 2013 in the Journal of Functional Foods, examined the effects of vinegar on markers of type 2 diabetes in at-risk adults. Average change in fasting glucose was reduced in the participants ingesting vinegar with meals, and fasting breath hydrogen (a measure of digestive processes) was elevated by 19 per cent.
Researchers said the data indicated that vinegar has antiglycaemic effects in adults at-risk for type 2 diabetes. How vinegar helps In adults with type 2 diabetes, previous research has shown that daily ingestion of vinegar lowered fasting glucose concentrations and glycated hemoglobin (A1c). Study method. Vinegar at mealtimes reduces risk factors for type 2 diabetes.
Gut bacteria may be key to treating a range of health issues, new analysis. September 30, 2013 Sophie Langley A new understanding of the essential role of gut microbes in the immune system may hold the key to dealing with some of the more significant health problems facing people in the world today, according to a new analysis from Oregon State University. Problems ranging from autoimmune to clinical depression and obesity may be linked to immune dysfunction that begins with a “failure to communicate” in the human gut, according to the researchers. The new analysis, published in the journal Clinical Reviews in Allergy and Immunology, suggests that health care of the future may include personalised diagnosis of an individual’s “microbiome” to determine what prebiotics or probiotics might provide better balance. “The human gut plays a huge role in immune function,” Dr Shulzhenko said.
“This is little appreciated by people who think its only role is digestion. Links to range of diseases Future therapies may work with microbiotic balance. DNA link to sugar impact risk for heart disease and diabetes. September 30, 2013 Sophie Langley Genes in mitochondria, the “powerhouses” that turn sugar into energy in human cells, shape a person’s risk for heart disease and diabetes, according to a study from researchers at the University of Alabama at Birmingham (UAB). The findings may have implications for diet-planning and the ongoing debates surrounding added sugars in foods and beverages. Researchers said the findings, published in the Biochemical Journal 8 August 2013, may explain why some people get sick and others do not despite having the same traditional risk factors like ageing, obesity and smoking. Research in recent years has shown that miscues in mitochondrial energy production create too many particles called oxidants and free radicals that cause cells to self-destruct as part of heart disease, diabetes and cancer.

Broccoli could be key to preventing and slowing osteoarthritis. September 9, 2013 Sophie Langley A compound found in broccoli could be the key to preventing or slowing the progress of the most common form of arthritis, according to new research from the University of East Anglia (UAE) in the UK. The study, which was published in the journal Arthritis and Rheumatism on 28 August 2013, showed that sulforaphane slows down the destruction of cartilage in joints associated with painful and often debilitating osteoarthritis.
Sulforaphane is released when eating cruciferous vegetables such as Brussels sprouts and cabbage, but particularly broccoli. The researchers found that mice fed a diet rich in the compound had significantly less cartilage damage and osteoarthritis than those that were not. Previous research has suggested the sulforaphane has anti-cancer and anti-inflammatory properties, but researchers said this was the first major study into its effects on joint health. Compound blocks ‘destructive’ enzymes Osteoarthritis in Australia.
The Nutrition Source » Carbohydrates and Blood Sugar. When people eat a food containing carbohydrates, the digestive system breaks down the digestible ones into sugar, which enters the blood. As blood sugar levels rise, the pancreas produces insulin, a hormone that prompts cells to absorb blood sugar for energy or storage.As cells absorb blood sugar, levels in the bloodstream begin to fall.When this happens, the pancreas start making glucagon, a hormone that signals the liver to start releasing stored sugar.This interplay of insulin and glucagon ensure that cells throughout the body, and especially in the brain, have a steady supply of blood sugar. Carbohydrate metabolism is important in the development of type 2 diabetes, which occurs when the body can’t make enough insulin or can’t properly use the insulin it makes.
Type 2 diabetes usually develops gradually over a number of years, beginning when muscle and other cells stop responding to insulin. Glycemic index Simple carbohydrates: Complex carbohydrates: Glycemic load High glycemic load (20+) Mother’s ‘junk food’ diet alters development of dopamine receptors in babies.
September 2, 2013 Sophie Langley Eating a diet high in fat and sugar during pregnancy changes the development of the opioid signally pathway in the baby’s brain and permanently alters the way this system operates after birth, according to new research from the University of Adelaide. Meanwhile, US research also shows the link between ‘feel good’ brain chemical dopamine and suggests obesity be classified as an “addictive disorder”.
Mother’s diet changes brain chemistry of offspring The Australian animal study, which was presented at the Annual Meeting of the Society for the Study of Ingestive Behaviour held in New Orleans 30 July 2013 to 2 August 2013, found that the gene encoding one of the key endogenous opiods, enkephalin, was expressed at a higher level in the offspring of rat mothers who consumed a diet high in fat and sugar compared with the offspring of mothers who ate standard rat feed. Opioids are chemicals that are released when foods that are high in fat and sugar are consumed.

Federal dietary guidelines recommending that Americans of all ages consume three cups per day of reduced fat milk or other dairy products may be influenced more by lobbying from the dairy industry than by scientific evidence, according to a new commentary co-authored by Walter Willett, Fredrick John Stare Professor of Epidemiology and Nutrition at Harvard School of Public Health.
He and co-author David Ludwig of Boston Children’s Hospital argue that a broader range of recommendations for milk consumption may be more appropriate. The commentary was published online July 1, 2013 in JAMA Pediatrics. Adults who eat a healthy diet may already be getting sufficient vitamin D and bone-building calcium from other sources such as kale or fortified orange juice, according to the researchers. Children may need the recommended daily glasses of milk if they have poor diets; however whether they should be drinking whole or skim milk is up for debate. Read Boston Globe article Learn more. Bacterial metabolites regulate immune system function in the colon and may help reduce inflammatory bowel disease. July 29, 2013 — Harvard School of Public Health (HSPH) researchers have discovered that chemicals generated by bacteria in the colon help important immune cells known as Tregs in the colon grow and function well.
The researchers also found that these bacterial metabolites reduced colitis in mice with inflammatory bowel disease (IBD), a chronic disease of the intestines that afflicts over two million people worldwide. “Increasingly, scientists, physicians, and the public are recognizing that the gut microbiota, the microbes that live within our intestines, shape our health and wellbeing in innumerable ways. We’ve identified that an abundantly produced microbial metabolite shapes the immune response,” said Wendy Garrett, senior author and assistant professor of immunology and infectious diseases at HSPH.
The study was published online July 4, 2013 and will appear in the August 2, 2013 print edition of the journal Science. Garrett hopes that the findings will translate to humans. Learn more. Bacteria identified that may lead to inflammatory bowel disease in genetically susceptible individuals. For immediate release: Thursday, September 16, 2010 Certain bacteria that inhabit the intestine provide the environmental trigger that initiates and perpetuates chronic intestinal inflammation in individuals who are genetically susceptible to inflammatory bowel disease (IBD), a study led by Harvard School of Public Health researchers has found.
Inflammatory bowel disease results from a loss of homeostasis, or balance, between the immune system and the microbes that inhabit the intestine. “In this study, we identified two microbes that instigate gut inflammation that leads to inflammatory bowel disease in mice,” said lead investigator Wendy Garrett, assistant professor of immunology and infectious diseases at HSPH. “We show using both metagenomic and conventional culture techniques that an individual’s genetic background influences what bacteria reside within his or her intestine. The study appears in the September 16, 2010, edition of Cell Host & Microbe. For more information: Gestational diabetes: The diagnosis debate. August 9, 2013 — Gestational diabetes—diabetes that women develop while pregnant—can lead to serious health problems for both babies and mothers. Babies can be born too large or have birth injuries. Mothers can face greater risk of needing a cesarean delivery.
For both mothers and babies, the risk of developing type 2 diabetes later in life can increase. But there’s a lack of clear evidence—and thus a lack of consensus—about the best way to test for and diagnose gestational diabetes. Harvard School of Public Health’s Michelle Williams gave an overview of the controversies and challenges surrounding gestational diabetes at a summer Hot Topics lecture at the School on August 6, 2013. Watch a video of the Hot Topics lecture “Gestational diabetes is one of those conditions where we just can’t seem to decide how to define it and how we should screen for it,” said Williams, Stephen B. Pregnancy as “stress test” “You have this metabolic state that’s primed for oxidative stress,” Williams said.
Skipping breakfast may increase coronary heart disease risk. July 23, 2013 — A new study from Harvard School of Public Health (HSPH) adds to evidence that eating breakfast is important for good health. HSPH researchers found that men who regularly skipped breakfast had a 27% higher risk of heart attack or death from coronary heart disease than those who did eat a morning meal.
Non-breakfast-eaters were generally hungrier later in the day and ate more food at night, perhaps leading to metabolic changes and heart disease. The study was published July 22, 2013 in the American Heart Association (AHA) journal Circulation. The scientists analyzed food questionnaire data and health outcomes from 1992-2008 on 26,902 male health professionals, ages 45-82. “It’s a really simple message.
