We all know the foods we eat provide our bodies with the energy necessary to live and move. The energy from the foods we digest also helps our bodies regulate and maintain our autonomous systems that run everything from our vision and nervous system to our sympathetic and parasympathetic systems that help control our lungs, blood pressure and heart rate.
Headaches are a common condition that affects millions of people around the world. In this article, we explore the science behind how diet and sugar consumption may affect the body and result in headaches for some people.
Various factors, including changes in blood sugar levels and the release of certain hormones in the body, and food chemical intolerance have been known to cause headaches; however, it's worth noting that not everyone is affected by diet in the same way, and some people may be more sensitive to its effects than others.
One of the many challenges of our food system and the economy generally is to decarbonise production systems, and become more fuel-secure by producing it here. Producing biofuel is one way to do this and making it from Australian sugarcane also has regional economic benefits by supporting more jobs through the supply chain. Biofuels are renewable liquid fuels, the most common is bioethanol but also bio-aviation fuel (BAF). In the case of sugarcane, biofuel can be made from the waste material-typically molasses- left after processing so it’s a win-win.
In a new pilot biorefinery plant based in Mackay Queensland, they are turning sugarcane crop waste called bagasse into renewable diesel and bio-aviation fuel under the watchful eye of researchers from the Queensland University of technology (QUT). Their challenge is to demonstrate the technology works and how it can be scaled-up to increase Queensland’s biofuel production capabilities. The aviation fuel can be used in the same way as traditional aviation fuel making the switch simple. This could enable carbon-negative jet fuel because sugarcane captures more carbon during growth than the engine emits during combustion. The same process could be used for other waste products from corn, wheat, barley, rice straw, sawdust and woodchips.

A new report published by KPMG from the Fruit and Vegetable Consortium (FVC*) and Medibank says eating habits worsened over the COVID-19 pandemic and recommends increased action to increase vegetable consumption. More than $200 million could be wiped from the Australian health budget if Australians ate an extra cup of vegetables each day. As well as improving health, increasing vegetable consumption will also benefit growers, regional communities, and retailers.
The report recommends:
Over the past few pandemic-affected years, Australians ate more take-away and home delivered meals, snacked more, and ate fewer vegetables. Chair of the FVC Lucinda Hancock from Nutrition Australia says the pandemic lockdowns made the existing barriers to vegetable consumption worse, such as affordability, concern over food waste and lack of time and inspiration to prepare meals.
“Governments have a range of good strategies to improve preventative health, reduce obesity, lift health literacy and reduce food waste. A national behaviour change campaign can empower consumers with the information they need to make the right choices for themselves”, said Ms Hancock.
*FVC is a collaboration led by Nutrition Australia and AUSVEG with 10 members across the health and horticulture sectors.

Sugarcane was in Australia from the beginning of white settlement, having been brought in the ships of the first fleet. Like many other crops, it did not do well in the early days of the colony. Shifting to the warmer climate of Queensland in 1862 was the change needed to start the commercial sugar cane farming and milling industry.
With growing labour requirements, a history of using convict labour, rampant slavery in other parts of the world and a lax approach taken by the Queensland government, the shameful chapter of using indentured labour from the South Pacific enabled the industry to grow through the hard labour required for cane cutting. While most workers came voluntarily, others were kidnapped, forced, coerced or deceived (known as ‘blackbirding’) to travel to Queensland from their island homes. The Federal Government legislation stopped this practice in 1901.
The early 1900s saw a wave of migrants arrive from Italy and many took up work in the sugarcane fields. The enterprising Italian migrants who went on to buy sugarcane farms have descendants in the industry to this day. The cultural legacy of European migration is still alive in Queensland.
In Australia, the Rationing Commission was established in 1942 to manage the limited supply of clothing, fuel and food available. In those days there were few processed foods, and most foods were cooked from scratch. Sugar was rationed to 2 pounds (900g) per person per fortnight (or 64g/day). This is higher than the WHO 10%kJ guideline of 50g a day or less for women and 60g for men (based on average energy requirements), and higher than current average intakes of added sugar in Australia of 52g a day reported by the Australian Bureau of Statistics (ABS). Other foods rationed were tea, butter and meat. Rationing went on for 8 years before being lifted in 1950.
Cutting sugar cane was backbreaking, slow and dangerous work so the advent of mechanical equipment for harvesting and loading in the 1960s revolutionised production making it faster, easier and cheaper.
Sugar mills are located close to where sugarcane is grown. Sugar is made by crushing sugarcane to extract the juice and then evaporating the moisture until crystals form. The cane fibre leftover is used to fuel the mill boiler and the molasses by-product of juice processing is used for distilling and stock feed.
The practice of burning sugarcane before harvest started in around 1935 after mass industrial action. The canecutters were catching Weil’s disease from rats that infested the cane and burning solved the rat problem. It also made cutting and loading easier by reducing leaf matter. However, as the population around cane fields and environmental awareness grew, people complained about the smoke and ash and the practice declined from the late 1970s. While it is still done in some places, most Australian cane farmers ‘green harvest’ without burning. Although it costs more, it also has agronomic as well as environmental advantages.
Lemonade made with water, lemon juice and honey was the first sweet drink marketed in Paris in 1676 and was sold from vendors with tanks on their backs. The bubbles (carbonation) came about to imitate naturally effervescent natural mineral waters sourced from springs, which were thought to have therapeutic value. In the early 1800s the process of carbonation was perfected. After making ginger, lemon and tonic waters, the iconic Coca Cola was invented by a pharmacist in Atalanta Georgia in 1886. The rest, as they say, is history. ‘Soft drinks’ were named to distinguish them from hard liquor and were promoted to avoid drinking too much liquor in the USA.
Sugar-sweetened drink consumption has been steadily declining in Australia, as shown in the per capita volume sales figures below (from Shrapnel & Butcher, 2020):
(a) all sugar sweetened vs non-sugar sweetened water-based beverages, and
(b) sugar sweetened vs non-sugar sweetened carbonated drinks:
Concerns about the adverse health effects of consuming too many sugar-sweetened beverages have resulted in ‘sugar taxes’ being introduced in several countries including Mexico and the UK. The Australian and New Zealand Governments have not introduced a sugar tax.
While the first non-nutritive sweetener (NNS), saccharine, was invented in the 1879 they only really started being used in the 1950s and massively increased in the 2000s. ‘No sugar’ and ‘diet’ drinks are their main application and use in these products continues to grow. Recent research shows use of NNS is higher in the food supply of countries who have taken policy action such as sugar taxes.
After importing refined sugar from Australia, New Zealand established its own refinery at Birkenhead in Auckland, forming the New Zealand Sugar Company in 1882, later becoming the Chelsea Sugar Company. Not having the growing conditions required for sugarcane, they purchased raw sugar from other countries such as Indonesia. During the 1930s depression era when most businesses were shedding staff, demand for sugar continued and the Chelsea Sugar Co. carried on business as usual, and workers kept their jobs. During WWII while men were off fighting, women took over the jobs in the sugar refinery. The land surrounding the refinery at Birkenhead is now a beautiful park owned by the Heritage Park Trust.
