Spending on pharmaceuticals is on the rise worldwide. And it well should be. Today, we are able to cure some diseases like hepatitis C that were virtual death sentences just a few years ago. This progress required significant investments by governments and private companies alike. Unquestionably, the world is better off for it.
Loneliness affects people of all ages, young as much as old. It’s now seen as so serious it’s classified as a public health problem. It’s presented as an “epidemic” causing a wide range of health problems that threaten to cripple health services.
For thousands of years people have used cannabis for recreational, ritualistic and medicinal purposes.

For every person in the world who receives a cornea transplant, there are 69 others who still need one. That leaves about 12.5m people with limited sight because there aren’t enough eye donors. But what if we could grow new corneas in the lab?
Plenty of us have been there: waking up after a night out with a thumping headache, feeling sick and swearing never to touch alcohol again. If only there were a way to prevent these terrible hangovers.
Breakfast, we are told, is the most important meal of the day. Over the last 50 years, we have been bombarded with messages extolling the health benefits of processed cereals and porridge oats.

Regular walking produces many health benefits, including reducing our risk of heart disease, type 2 diabetes and depression. Best of all, it’s free, we can do it anywhere and, for most of us, it’s relatively easy to fit into our daily routines. We often hear 10,000 as the golden number of steps to strive for in a day. But do we really need to take 10,000 steps a day?
For most people, teeth cleaning may just be a normal part of your daily routine. But what if the way you clean your teeth today, might affect your chances of getting Alzheimer’s disease in years to come?

Antibiotic resistance in bacteria is spreading rapidly worldwide and has even been called a global threat to humans as serious as climate change. Excessive and imprudent use of antibiotics is usually blamed, but the rate and extent of the spread can’t be explained by overuse alone.
Meal-replacement diets, where some meals are replaced with soups, shakes or bars, have been making a comeback. They first took off during the early days of space travel when the public became obsessed with the idea of a nutritionally complete meal in a single drink or bar. These products remained popular for most of the 70s and 80s, but gradually fell from favour as people began to question the health benefits of these diets.
Do you prefer to rise early with the lark or stay up late with the owl? Your preference turns out to be partly decided by your genes.

Many people do not want to think about dementia, especially if their lives have not yet been touched by it. But a total of 9.9 million people worldwide are diagnosed with dementia each year. That is one person every 3.2 seconds.
Whether waiting for a bus, playing outside or walking the dog – during the colder winter season, everyone is looking for ways to stay warm. Luckily, the process your body uses to break down foods serves as an internal heater.
I recently visited the Hermitage in St Petersburg, Russia – one of the best art museums in the world. I was expecting to serenely experience its masterpieces, but my view was blocked by a wall of smart phones taking pictures of the paintings.

Almost half of all Canadians regularly take at least one nutritional supplement such as vitamins, minerals, fiber supplements, antacids and fish oils. Many of these individuals are healthy and hoping to improve general well-being or prevent chronic disease.
We all know the advice for healthy teeth – brush twice daily and don’t eat too much sugar. So why do those of us following these instructions find we sometimes need a filling when we visit the dentist? The truth is, there’s a little more to preventing tooth decay than these guidelines suggest. Here’s what you need to know.
Messenger RNA, which can induce cells to produce therapeutic proteins, holds great promise for treating a variety of diseases. The biggest obstacle to this approach so far has been finding safe and efficient ways to deliver mRNA molecules to the target cells.
There is a growing global trend to consider pets as part of the family. In fact, millions of people around the world love their pets, enjoying their companionship, going for walks, playing and even talking to them.

If you feel you consistently fail at your New Year’s resolutions, you are not alone. Despite our good intentions, we’re pretty poor at changing our own behavior. We continue to smoke, eat or drink too much, and exercise too little, all of which affect our health and well-being.
