Global physical activity levels

Major study was published in Lancet yesterday reporting that 25% of the people worldwide do not exercise enough in terms of their health. According to its conclusions, policies to increase population levels of physical activity need to be prioritised and scaled up urgently. I could not agree more, but on the other hand 75% of the world population are exercising quite nicely.

Particularly Finns exercise quite a lot as Finns lead the statistics amongst the western countries. Obesity and many chronic diseases are still quite common also in Finland, which makes me to ask whether even that amount of exercise that Finns do is enough to maintain or improve health? Or are these surveys, which are not relying on objective measures to determine physical activity, even misleading? How much should we actually exercise? Maybe 2-3 hours per day, as also suggested for kids?

Further, one could think based on these data that many persons are quite well-informed and health concsious as they are exercising. However, according to this study this might not be the case, but we need to continue to inform people in regards to health hazards of lack of exercise.

Recent important articles dealing with nutrition and health

I tweeted recently few posts in regards to nutrition and human health. According to one leading expert in the field, The field needs radical reform: “Some nutrition scientists and much of the public often consider epidemiologic associations of nutritional factors to represent causal effects that can inform public health policy and guidelines. However, the emerging picture of nutritional epidemiology is difficult to reconcile with good scientific principles.”

Another article discusses Food based dietary patterns and chronic disease prevention. Can specific foods provide health benefits? Will adopting a specific food pattern prevent major chronic diseases such as type 2 diabetes, cardiovascular disease, or cancer? You can find answers from their text.

Both articles are worth reading to guide eating decisions.

Cancer and bad luck

In my previous blog I wrote about the importance of physical activity in the prevention and treatment of cancer, but it is also worth of mentioning that according to a recent study majority (2/3) of the cancers might actually be due to random cell divisions, thus pure bad luck. You can read more about the topic and get further perspectives for instance from this article that I found balanced and informative.

Workout cancer – interview with Ken Martin

It is such a pleasure to have the very first interview with Ken Martin, who is a runner but who has also had quite some health difficulties as he has also suffered from cancer. He has however been a true pioneer as a cancer patient as he must have been one of the first ones if not the first who systematically started to exercise while receiving cancer therapies. Let’s hear how he is doing currently.

Exercise prevents cancer

Different types of cancers are becoming more and more common particularly in Western societies, partly due to the fact people are aging and living longer. However, lifestyle also contributes, and physical activity is one of the most important lifestyle factors in cancer prevention. In this regard a major study was published last year (20016) showing based on 1.44 million adults that physical activity lowers the risks of 13 out of 26 different cancer types that were investigated. On the other hand too much sitting also appears to promote the development of at least certain cancers, such as breast and colorectal  cancers.
