The idea that healthy food costs more than junk food is something I hear a lot. Students tell me they’d like to eat better but can’t afford to. There is a strong belief that cooking from scratch costs a fortune, and with takeaway meals priced as low as £1, they have little incentive to change their behaviour.
We all know eating “healthy” food is good for our physical health and can decrease our risk of developing diabetes, cancer, obesity and heart disease. What is not as well known is that eating healthy food is also good for our mental health and can decrease our risk of depression and anxiety.
Leftovers may be throwing off your sense of how much you’ve actually eaten and how much you need to exercise, particularly as portion sizes—and therefore leftover portions—increase, according to a new study.
Worldwide obesity has tripled since 1975, with 1.9 billion adults considered overweight. The condition now kills more people across the globe than underweight and malnutrition.
One of the NHS’s biggest cost burdens, a staggering 70% of UK adults are expected to have overweight or obesity by 2034. Obesity is a problem of energy balance.
Last week I had a shocking cold. Blocked nose, sore throat, and feeling poorly. This made me think about the countless vitamins and supplements on the market that promise to ease symptoms of a cold, help you recover faster, and reduce your chance of getting another cold. When it comes to the common cold (also called upper respiratory tract infections) there is no magic cure (I wish) but some supplements may deliver very minor improvements. Here is what the latest research evidence says.
Alcohol producers and retailers have long argued that their goal is a world where everyone drinks responsibly and heavy drinking is a thing of the past. As a result, the alcohol industry claims to be part of the solution to the UK’s drink problem rather than part of the problem. In our latest research, published in Addiction, we examine the credibility of this claim.
Timing our meals can fend off diseases caused by bad genes or bad diet. Everything in our body is programmed to run on a 24-hour or circadian time table that repeats every day. Nearly a dozen different genes work together to produce this 24-hour circadian cycle. These clocks are present in all of our organs, tissues and even in every cell. These internal clocks tell us when to sleep, eat, be physically active and fight diseases. As long as this internal timing system work well and we obey them, we stay healthy.
We are still in love with vitamins a century after they were discovered, with half the US and UK population taking a supplement. Vitamin D – the sunshine vitamin – is the favourite and is believed to have the most proven benefits. Governments, including the UK government, have said that the evidence for vitamin D’s health benefits is so overwhelming that every adult should take it as a supplement for at least six months of the year.
A solid white mass found in a broken jar in an Ancient Egyptian tomb has turned out to be the world’s oldest example of solid cheese. Probably made mostly from sheep or goats milk, the cheese was found several years ago by archaeologists in the ancient tomb of Ptahmes, who was a high-ranking Egyptian official. The substance was identified after the archaeology team carried out biomolecular identification of its proteins.
Many parts of the country have seen episodic crises due to synthetic marijuana, the largest occurring in Mississippi, where 721 adverse events were logged between April 2-3, 2015. Even with outbreaks aside, synthetic cannabinoids are 30 times more likely to harm you than regular marijuana.
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.
If you drink alcohol, it’s likely you’re familiar with some of the effects of a hangover. Headaches, nausea and fatigue are just some of the unpleasant but common experiences of the morning after the night before. But have you ever wondered how a hangover may influence your thoughts and behaviour?
Eating a diet that is rich in fruits, vegetables, and whole grains and low in added sugar, sodium, and processed meats could help promote healthy cellular aging in women, according to a new study.
It’s been a busy summer for food-based biotech. The U.S. Food and Drug Administration made headlines when it approved the plant-based “Impossible Burger,” which relies on an ingredient from genetically modified yeast for its meaty taste. 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. As the number of new cancer cases per year is expected to rise to 23.6 million by 2030 worldwide, people are desperate for answers, turning to alternative therapies that fall outside the typical “slash, burn, poison” treatment model. 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.
A recent Daily Mail article announced that: “Beer is officially good for you”. The article claimed that beer “reduces heart risk” and “improves brain health”. Even if “heart risk” sounds a bit vague, the news sounds good. But let’s take a closer look at the evidence.

Veganism, the plant-based diet which shuns meat and dairy, is having its time in the sun. Since 2008, there has been a 350% increase in the number of self-described vegans in the UK alone. Where this motivation stems from is varied, but includes concerns about animal welfare, worries about the environment and religious reasons.
A diet developed in the 1920s to treat children with epilepsy is suddenly all the rage. The ketogenic diet, or “keto diet”, has reportedly been endorsed by celebrities and even athletes are giving it a go.
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.
The level of sugar in an individual’s blood—especially in individuals who are considered healthy—fluctuates more than traditional means of monitoring, like the one-and-done finger-prick method, would have us believe, according to a new study.

In the past, food scientists like me often praised mushrooms as healthy because of what they don’t contribute to the diet; they contain no cholesterol and gluten and are low in fat, sugars, sodium and calories. But that was selling mushrooms short. They are very healthy foods and could have medicinal properties...
Socioeconomics play a significant role in attitudes about food – especially concerns about safety and purchasing behavior. And higher income doesn’t always correlate with informed choices. On the contrary, our research shows that affluent Americans tend to overestimate their knowledge about health and nutrition.
