Time-restricted eating (also called time-restricted feeding) is a new dietary concept that involves reducing the time between the first and last calorie consumed each day. There is strong evidence to support the health benefits of time-restricted eating (TRE) in animals, and recent small studies by our research group and others suggest possible benefits for humans, too.
Anorexia nervosa is a psychiatric illness that primarily effects young people during their adolescence. While anorexia is relatively uncommon, affecting about 1 percent of the population, it can be lethal. Indeed, despite its relatively early onset, anorexia can last for several decades for more than half of those afflicted. It can lead to many associated psychiatric and medical risk factors, which in part explains why anorexia has the highest mortality rates of any psychiatric disorder.
The news that, after 106 years, Captain Scott’s fruitcake was found by the Antarctic Heritage Trust and “smelled edible”, raises the question: are there other foods that have similar staying power? The answer is, yes, several.
Everybody knows that to lose weight you should eat less and move more. But, of course, it’s not that simple; the combination of today’s environment and human biology can make it really, really hard to shed pounds. To reduce diseases caused by being overweight or obese, society needs to change, but those changes will be slow to come. We need effective weight-loss strategies now.
When you think of sugar, you probably think of the sweet, white, crystalline table sugar that you use to make cookies or sweeten your coffee. But did you know that within our body, simple sugar molecules can be connected together to create powerful structures that have recently been found to be linked to health problems, including cancer, aging and autoimmune diseases.

It’s been a busy summer for food-based biotech.

The European Union sparked controversy by extending heavy restrictions on genetically modified organisms by classifying them as gene-edited crops.
Despite its environmental benefits, using local seaweed for food can be a tough sell. Some think the Dutch have finally cracked the code. “Is seaweed a vegetable?” a wide-eyed child asks a tall man chopping kelp at a “Taste the Nature” market in the Zuiderpark city farm in The Hague. “Well, it has lots of vitamins and minerals,” the cook, Jethro van Luijk, replies.
Almost 40 percent of Americans can expect a cancer diagnosis in their lifetimes.

A review of the documentary “The Food Cure,” which follows patients undergoing an intensive and controversial nutritional therapy.
Caffeine is our favourite drug. But if we miss out on our fix, it can be a real headache, in more ways than one. Caffeine is a stimulant. It quickly enters our brain and blocks the (adenosine) receptors that are responsible for dulling brain activity. By blocking the dulling of our brain, we feel a sense of invigoration, focus and subtle euphoria. These feelings can also enhance our performance of certain focused tasks, like driving or staying awake through the whole lecture.
Obesity levels in Australia and around the world are high and rising. This comes at an enormous economic cost for society and individuals, not only in terms of health care and productivity, but also in lost quality and duration of life. Both behavioural economics research and weight-loss trials show that relying solely on Australians to take personal responsibility is doomed to fail, unless governments step in to create environments that promote healthy food and physical activity.
With the school year starting again, it’s time to start to think about the routine of packing school lunches. For many time-pressed parents, this is a formidable task. But it doesn’t need to be.

Red meat is an excellent source of protein and essential nutrients such as iron, zinc, vitamin B12 and omega-3 fats, which are are linked to heart and brain health. But while a small quantity of lean meat may be good for us, too much red or processed meat can increase our risk of some cancers.
