Ageing is related to metabolism
The authors of this study have identified 9 key aspects of ageing on your metabolism. Metabolism isn’t some organ or group of organs but it is a complete system created by the working of billions of cells inside our body. This system is responsible for converting the fuel or food we take into to energy so that our body can function.
With age, the metabolic process slows down. DNA gets damaged and this introduces errors and inefficiency is the entire workings of the cells. The process of destroying old and worn out cells (autophagy) also slows down and this failure has detrimental effect on our whole body. Our body experiences so much stress during the course of its life that it becomes difficult for it to perform well with age.
Ageing cannot be stopped but it can be slowed down
If ageing is all about metabolism, then it wouldn’t be surprising for you that the food we eat has a lot of affect on the ageing process. It is suggested that a Mediterranean diet can help extend your life. So what exactly is a Mediterranean diet? It is a diet high in healthy fats like olive oil, vegetables, whole grains, fish etc. However, it involves very little amount of red meat and sugar. Apparently replacing proteins with complex carbohydrates is healthier for us and aids in a longer life.
It doesn’t end here. Calorie restriction is also necessary. Overeating is not to be done and studies also suggest that introducing periods of fasting in your diet is also beneficial for some people. And the last one should not be a surprise to us; regular exercise. This helps all nine aspects that were identified in the paper that cause ageing.
Our unhealthy Lifestyles are slowly killing us
Improvements in health facilities, sanitation etc may have aided in increasing the life span but there are still problems that exist. Diets that are high in sugar, unhealthy fats and red meat create a lot of stress for metabolism and makes it inefficient. This increases the chances of obesity.
As most of us know, America is a place that has been struck with the problem of obesity. Americans have failed to consume healthy diets and spend far too many hours in activities that do not allow a lot of movement. The problem is serious and the authors have tried to call the people to immediate action if they wish to live a healthier and a longer life.
I liked this study as it brings together dozens of studies on ageing and combines them together to create a more knowledgeable source for us. Most of the researches that have been done in the past are mostly done on lab animals, whereas, only a fraction of these studies are based on human trials. This study combines various studies and tries to bring out a broader aspect to the previous unclear studies and now it can only be hoped that people recognize the importance of a healthy lifestyle after reading this paper.
