Why you have to know your body mass index

Why is it important for you to know your body mass index? Because if a person's BMI is out of the healthy range, their health risks may increase significantly. It’s good for you to keep track on your BMI so that you can take measures when need it, like losing or gaining weight.

Although a person with a body mass index over 25 is considered overweight, new studies suggest it may not be quite as bad as experts thought. Health.com wrote about one study that used data from three different periods—1976 to 1978, 1991 to 1994, and 2003 to 2013, examining the link between the BMI and mortality in 120,000 people. Researchers think that people who are a bit heavier are the least likely to die young.

The research showed that the participants in the study (1976 to 1978 period) with the lowest risk of death were those who had a BMI of 23.7, in the middle of the healthy range. In the second sample (1991 – 1994), the mortality rate was lowest for people with a BMI of 24.6 (which is at the upper limit of the healthy range). Looks like things have changed in time. In the most recent group (2003 - 2013) those with a BMI of 27, in the middle of the overweight range, had the lowest risk of dying.

Well, that’s the discovery. But no one knows why things have changed. Danish researcher Børge G. Nordestgaard cautions people not to get the wrong idea from his research. You still cannot eat whatever or whenever you want if you want to be healthy. Also, you don’t have to gain weight to become overweight to live longer.

I’m Raluca and I just peeled a peach before eating it, and I swear it tasted like the nectar of the gods. When it comes to cooking, I only have one rule: do whatever it takes to turn the whole thing into an enjoyable experience. When I was a little girl, I dreamed of cooking for sailors. Not because I loved food, but because I was madly in love with my godfather, who worked on a ship. But, as they say, love lasts three years, and I took a different path: I became a journalist who enjoys food, traveling, and hiking in nature. I usually cook for myself and my daughter, but my favorite meal is the one I'm having on a mountain peak, even if it's just a sandwich and a piece of chocolate.
