Do you feel like nutritionists are always changing their minds? Do you want science-based information about diet but don’t know whom or what to believe? Science can help you decide which diet works best for you
Do you remember your first kiss? What about your grandma dying? Chances are you do, and that’s because emotional memories are at the core of our personal life story. Some rare moments are just incredibly intense and stand out from an otherwise repetitive existence of sleeping, eating and working. That said, daily life, too, is replete with experiences that have a personal emotional significance – such as disagreeing with someone or receiving a compliment.
Wandering through the grocery store, it is easy to be overwhelmed by the numerous brands and health claims on the dozens of sugar substitutes. It can be particularly confusing for those with diabetes or pre-diabetes who must keep their blood sugar in check and control their weight.
How can you know that any animal, other human beings, or anything that seems conscious, isn’t just faking it? Does it enjoy an internal subjective experience, complete with sensations and emotions like hunger, joy, or sadness? After all, the only consciousness you can know with certainty is your own. Everything else is inference. The nature of consciousness makes it by necessity a wholly private affair.
Dreams can often be confusing and blurry experiences. Reduced critical thinking, little to no access to our true memories and heightened impulsivity and emotions during normal dream states often make for head-scratching moments when our eyes first open in the morning.
Many will have read the news story about the sad death of Cameron Gosling who died from cold water shock after jumping into the River Wear on a hot summer’s day. Sadly, Cameron’s death is not an isolated case. About 400 people die annually in the UK as a result of being immersed in cold water – more than die from cycling accidents or fire. Most of the casualties are males under 30 years of age, and most are reported to be good swimmers.
Honesty is one of the traits we value most in others. We often assume it is a rather rare quality, making it important for us to find out who we can actually trust in this selfish world. But according to new research, there’s no need to be so cynical – it turns out most people in the world are honourable enough to return a lost wallet, especially if it contains a lot of cash.
In Australia, an average baby boy born in 2016 could expect to live to 80, while a baby girl born at the same time could expect to live until closer to 85. A similar gap in life expectancy between men and women is seen around the world.
Outdoor air pollution has been widely studied and regulated for decades, but the quality of indoor air and its potential risks were little unrecognized until the early 2000s. Yet in temperate climates we can spend up to 90% of our time in closed environments (houses, schools, offices, transportation, etc.), where we may be exposed to numerous pollutants. The question of indoor air quality has therefore become a major public health concern across the globe.
We know we should eat less junk food, such as crisps, industrially made pizzas and sugar-sweetened drinks, because of their high calorie content. These “ultra-processed” foods, as they are now called by nutritionists, are high in sugar and fat, but is that the only reason they cause weight gain? An important new trial from the US National Institute of Health (NIH) shows there’s a lot more at work here than calories alone.
Many people spend the majority of their waking hours sitting – at home, commuting and at work. Particularly when we’re sitting for long periods at a desk, there are a few things we should keep in mind.
Humans are living longer around the world. While there have been obvious ups and downs, life expectancy at birth overall has been steadily increasing for many years. It has more than doubled in the last two centuries.
On the one hand, cheese is an excellent source of minerals like calcium and magnesium, vitamins A, B2 and B12, not to mention being a complete protein. On the other hand, cheese is also a significant source of saturated fat and sodium in our diets. To lower saturated fat intake, consuming reduced-fat cheese is sometimes recommended to lower cardiovascular disease risk.
