In a couple of previous posts I have been writing about calories density as a factor in obesity. In my first post, I lay down the idea that human societies have shifted from low energy dense foods (meat and vegetables) to high calories dense foods. The fact that the humans seem not to have a mechanism to regulate the amount of food eaten when the regardless of the density of the calories may be an explanation of why we are eating too many calories. I wrote abou this in my second article.
Could oils be the culprit for those extra calories added to the diet due to the lack of regulation of calories intake?
Look at this graph made with daat fron the USDA
You can see how total fat consumption has increased over the last 50 years. Interestingly, consumption of table spreads (butter and margarine), the ones that we have been told are bad for you because they are full of saturated fats, has decreased while oils consumption (the ones that we have been told are good for our health) has increased.
Now it becomes aparent that we are eating too much of added oils, which are energy dense, and if we do not have the mechanisms to regulate the amount of food intake when we eat caloric dense foods, then, we are eating (just because the oils) too many calories, which of course, will eventually lead us to gain weight.
We also need to consider that this added consumption of oils may be damaging to our innate ability to regulate the body weight set point or even the fat body set point. But this idea may be explained later
