It isn’t surprising that people are confused about nutrition when the media presents different findings as gladiatorial battles: vegetarian versus carnivore, high-fat versus low-fat diets and, more recently, low-carb diets versus high-carb. But, when you dig down into the data, many of these studies are reporting surprisingly similar things – and this is the case with the latest studies reporting on carbohydrates and health.
Night has always been a difficult realm for humans: we’ve had to learn to cope with the cold and the dark to thrive in it. Since the industrial revolution we’ve found ways to adapt our homes and cities to operate during the night. But as our conquest of the dark continues, the border between night and day is becoming increasingly blurry.
The credibility of scientific findings hinges on their reproducibility. As a scientist, it is therefore disastrous when you are unable to replicate your own findings. Our laboratory has found itself in just this situation several times; in each instance, unintended environmental exposure distorted our data. Our first accidental foray into toxicology 20 years ago convinced us of the need to understand the reproductive effects of environmental chemical contaminants. The latest twist in our journey down that road adds a new dimension to an old concern, BPA.
The link between gut microbes and health is now well established. As a result, researchers have been investigating the effects of probiotics, prebiotics and synbiotics on various diseases.
India has a reputation as a vegetarian nation, and Indians certainly consume far less meat than the global average. But the view of India as a predominantly vegetarian nation may not be quite accurate.
Walking significantly lowers the risk of heart failure in older women, a new study shows. The study of more than 137,000 postmenopausal women aged 50 to 79 is the largest and most comprehensive to date that has evaluated physical activity within the context of heart failure prevention.
The sensation of sound occurs when the vibrations from sounds enter our ear and cause little hairlike structures – called hair cells – within our inner ear to move back and forth. The hair cells transform this movement into an electrical signal that the brain can use.
Suicide rates in the United States have increased by 25-30 percent since 1999. This is particularly true for youth ages 12-24, with increases of approximately 30 percent over the same period. In Alachua County, Florida, where I teach and practice at the University of Florida, the base rate for suicides among youth ages 12-17 had been about five per 100,000 for many years, below the base national rate of 13 per 100,000. However, in the year 2017 that rate of completed suicides increased to 27 per 100,000, and for 2018 we are at a pace that will likely equal 2017.
Ever been in a situation where passing wind is going to be hugely embarrassing and you’ve had to hold in a fart? Let’s face it – we all have. Trying to hold it in leads to a build up of pressure and major discomfort. A build up of intestinal gas can trigger abdominal distension, with some gas reabsorbed into the circulation and exhaled in your breath. Holding on too long means the build up of intestinal gas will eventually escape via an uncontrollable fart.
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.
Your body’s internal clock – the circadian rhythm – regulates an enormous variety of processes: when you sleep and wake, when you’re hungry, when you’re most productive. Given its palpable effect on so much of our lives, it’s not surprising that it has an enormous impact on our health as well. Researchers have linked circadian health to the risk of diabetes, cardiovascular disease and neurodegeneration. It’s also known that the timing of meals and medicines can influence how they’re metabolized.
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.
No matter how much we try to minimise our exposure to respiratory viruses, it’s far more difficult in winter when we spend so much time in close proximity to other people.
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.
The brain has no nociceptors – the nerves that detect damage or threat of damage to our body and signal this to the spinal cord and brain. This has led to the belief that the brain feels no pain. A belief that has entered popular culture.
In the 2001 movie Hannibal, there is a gut-twisting scene in which the eponymous Hannibal Lecter cuts out part of the brain of an FBI agent who is fully awake, though drugged, and seated at a dinner table.
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.
Nine in ten young women experience the cramping or stabbing of period pain just before their monthly bleed or as it starts.
Period pain (also called dysmenorrhoea) can be divided into two main types – primary or secondary dysmenorrhoea – depending on whether there’s an underlying problem.
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.
Increasing the amount of exercise is one way to use the energy stored in fat cells, or to ‘burn’ fat. Many of us may be considering “burning some fat” so we feel better in our bathing suits out on the beach or at the pool. What does that actually mean, though?
The number of studies that have found a link between a disease and a specific gut microbiome composition seems to be ever increasing. Until recently, though, almost all these studies have looked at single diseases in isolation. But most people tend to have more than one health complaint at a time – “comorbidities”, in medical parlance.
