Sugar in the spotlight
Quite often the words sugar, excess energy, higher GI and weight gain appear hand in hand. So it’s understandable that many Australians look at the sugar content of breakfast cereals when selecting the healthier option, however a recent research makes us think again. A study of the breakfast cereals available in Australian supermarkets has found that there is no link between the amount of sugar and the number of calories energy or GI of the cereal. To choose a healthier breakfast option instead of looking at the sugar content, think positive and choose nutrient rich whole grain or high fibre breakfast cereals.

Give whole grains a go
Establishing a healthy habit takes effort, however unlike some healthy habits eating whole grains appears to be easier to maintain in the long run. Participants in a recent study were encouraged to swap to whole grains for 4 months. When researchers followed up a year later they found that participants were eating more whole grains compared to their original diet despite the study having finished. Whole grains are nutrient dense and are promoted by health authorities around the world for their health benefits. If you haven’t given whole grains a go why not start now, it’s as easy as choosing a whole grain cereal for breakfast and whole grain bread for lunch.

Want to live a long and healthy life?
An Australian study of 2890 older Australians found that those whose dietary habits followed the dietary guidelines reduced their risk of death by 21% over a 15 year period. The recently updated Australian Dietary Guidelines provides a timely reminder for us to see how our diet compares. Following the guidelines ensures you receive the full range of nutrients needed for health and disease protection. An easy way to check the health of your diet is to ask yourself whether your everyday diet is based on the five core food groups which include grains (mostly whole grain and high fibre), fruits, vegetables (including legumes), lean proteins and low fat dairy.

Kamut an Ancient Grain
Kamut is an ancient variety of wheat with 21st century health potential. A recent study compared heart health measures of 22 healthy people for 2 months while they ate either Kamut wheat products (bread, pasta and crackers) or semi whole grain wheat products. Researchers found that eating Kamut products improved heart health by reducing inflammation and cholesterol levels. This study, although small, highlights the potential of Kamut as another whole grain with health benefits. As the research continues to unlock the health benefits of ancient grains like Kamut, keep an eye out for these ancient grains in your super market.

GI of rice varieties
Following on from the recent discovery that most rice varieties have a low or moderate GI, here are some additional findings of the study conducted by CSIRO researcher DrMelissa Fitzgerald:
- Australian rices are in the medium range of GI.
- GI values of the 235 varieties tested ranged from 48-92.
- The lowest GI rice was a variety from the International Rice Research Institute, followed by an old Chinese variety called Shan-Huang Zhan-2.
- In general varieties from South Asia, including India , Bangladesh and Sri Lanka were in the lower end of the GI range. A popular variety from south India called Samba Masoori was the fifth lowest GI.
- In general varieties from South East Asia, were in the slightly higher end of GI values, with rices from Loas and Thailand having the highest GI.
Research also identified the key gene that determines the GI of rice, and so we are likely to see more specialised low GI varieties on our supermarket shelves in the near future.

Sugar in the spotlight
It has been suggested that sugar intake is linked to the risk for obesity and, although the mechanisms remain unclear, energy density and glycaemic index (GI) may be relevant. This study conducted a systematic survey to investigate the relationships between sugar content, energy density and GI in Australian breakfast cereals. Results indicated that there was no relationship between sugar content and energy density. GI information was available for 43 products and there was no association between sugar content and GI. The author concluded that sugar content of breakfast cereals is a poor indicator of energy density and GI and the continued focus on sugar in dietary guidelines and nutrition advice may need to be reconsidered, at least in relation to solid foods.

Give whole grains a go
Whole grains are recommended around the world by health authorities for their suggested health benefits. However, as we know, converting public health recommendations into long term improvements in a population’s diet is challenging. This study assessed the impact of a 4 month whole grain intervention on subsequent elective whole grain intake. The results showed that whole grain intake was significantly higher (approximately double) in people who had previously received whole grain foods as part of an intervention, compared to a control group. This increased whole grain intake resulted in an average increase in fibre intake by 2-3g/day. It appears that a period of direct exposure to whole grain foods in people who don’t usually eat whole grain food may benefit subsequent elective dietary patterns of whole grain consumption.

Want to live a long and healthy life?
This study investigated the relationship between diet quality reflecting adherence to dietary guidelines (including the core food groups) and mortality in a sample of 2897 Australians aged 49 years or older. Baseline dietary data was collected during 1992–4, and the Australian National Death Index provided 15-year mortality data. People in the group who displayed the highest dietary quality based on the dietary guidelines had a 21 % reduced risk of all-cause mortality compared with those assess as having the lowest quality diet. The present study provides support for a reduced risk of all-cause mortality in an older population who have greater compliance with the dietary guidelines during the study period.

Kamut an Ancient Grain
Kamut is an ancient variety of wheat with widely acclaimed health benefits. This randomized, cross-over trial involving 22 healthy subjects examined the effect of a replacing semi-whole grain wheat products with Kamut products on cardiovascular health measures over 8 weeks. Kamut products showed a significant reduction of metabolic risk factors such as total cholesterol (mean reduction: -8.46?mg/dl; -4%), LDL cholesterol (-9.82?mg/dl; -7.8%), blood glucose and marker of inflammation. The Kamut products diet also resulted in an increase of serum potassium and magnesium. The authors suggest that a replacement diet with Kamut products could be effective in reducing metabolic risk factors, markers of both oxidative stress and inflammatory status.
