    So how much fat to protein would you say is in a single chicken breast?

  • wickedchicken

    There is so little visible fat on chickens e.g. a skinless chicken breast. I don’t see how it’s such a high ratio.

  • Michael Greger M.D.

    Much of the fat in chicken is in the muscle (meat) itself, what’s called intramyocellular lipid, where droplets of fat build up inside the muscle cell itself. In fact that’s why chickens are used as experimental models of human obesity, since the buildup of fat inside our own muscles is thought to contribute to the insulin resistance associated with type 2 diabetes, and chickens are one of the few animals fat enough mirror our obese population. This month in the medical journal Stress, for example, a team of Chinese scientists found that stress hormones may actually facilitate this process of fat accumulation within the muscles of chickens, raising the question of whether the conditions in which most chickens are raised these days may indeed be making their nutritional profile even worse as suggested in the “Modern Organic and Broiler Chickens Sold for Human Consumption Provide More Energy from Fat than Protein” article I profile in the Does Eating Obesity Cause Obesity? video.

    oh my, that is shocking. thanks, i never knew!

    Why is it that the USDA states that a chicken breast only has 6 grams of fat and 2 grams of saturated fat when this study shows otherwise. Is the methodology used in the USDA lab study folly?

    I need to see more of these videos and posts.  I respond to these graphic facts.  I haven’t made meat of any kind a staple of my diet for years, but still wondered if I’m doing the right thing.  You have put the nail in that…uh, box!  Thank you.  Now I am more and more sure that my plant based, fruit and vegi diet is the right thing for me.  Now I need to decide if I should be concerned about every little nutrient, or just go for the fruit and green vegis as a mainstay and not worry about it.  I am due for my blood tests, so that might help in my decision.  Still trying to learn all about the low fat vegan diet and what is good for me.  Altho, I have been mostly vegitarian for 32 years, I am trying to refine it to avoid the perils associated with old age.  

    I love your site; both for the info you give and the intelligent responses.  Thanks everyone.  You may never know how much encouragement from you all.  Lynn

    I’m puzzled as to how the caloric and fat values are determined in this video. If one gram of fat has 9 calories, then a 16 calorie serving of chicken in the early 1900s would derive all of its calories from fat and no calories from anything else. If a present day chicken serving has 23 grams of fat, that would equate to 207 calories from fat. Your data gave 208 calories for one serving, suggesting that one calorie came from something other than fat. Is this possible?

    At 1:36, it sounds like you say, “Unknowingly feeding their chicken on a high fat…”

  • Chahna

    So the implication is that modern producers of chicken meat are rearing animals that are unfit for the health of the general population. The information provided by the studies and presented here does not translate to the labeling of the chicken products we are buying in our supermarket now. Do these types of rearing and farming problems also apply to other meat sources? What about polluted fish? Soil is depleted and polluted and there is plenty of information about this. Water sources are unfit to drink. What chance does the ordinary consumer stand, in a market full of misinformation and blatant omissions, to eat a healthy and balanced diet? Is there any wonder there are so many obese people?

    Dear Doctor Gregar,

    This seems to be confirming the points that paleo people are trying to make. Of course a real freerange chicken that was living outside with lots of space, that had to work for getting it’s food etc etc would be much more healthy than an industry chicken.

    But what is the health benefit of a healthy vegan diet over a similar diet that included said healthy chicken? Has there been any studies on that subject?

    The average paleo diet still seems to be based on carb restricting so that won’t count as a healthy diet.
