 Hi, this is Dr. Reshow and let's discuss if red meat is bad for you. Certainly, for someone who's trying to be healthy, there's a few pieces of dietary advice you've likely heard. Whether they're true or not true, avoid fat or eat lots of healthy fat, avoid red meat or eat red meat, eat lots of vegetables, eat lots of fiber, common things that we kind of throw around. One of them is red meat. There's definitely two kind of maybe polarizingly opposite opinions on red meat. Some people, mostly in the paleo or ancestral community, believe that our hunter-gatherer ancestors routinely ate red meat and it's an important part of a healthy diet. On the other end, there are people of maybe a more vegetarian type of persuasion that argue that red meat consumption is associated with obesity, heart disease, cancer. It's hard to get a good read on this, which is understandable. As someone who sees the merit in both of these dietary camps, admittedly, I'd lean a little bit more in the paleo direction, but clearly there's evidence showing that all of these different dietary types from vegetarian all the way through paleo diet have merit and can help. It's hard though to try to parse through and find where the truth is. A recent study was published that I found to be very interesting and I thought you might find it interesting also. I'll put the abstract of the study up here on the screen. The study is entitled Health Risk Factors Associated with Meat, Fruit, and Vegetable Consumption, a Cohort Study, a Comprehensive Med Analysis. The Comprehensive Med Analysis part of the title of the study is very important because the Comprehensive Med Analysis means that essentially a group of researchers went out and they reviewed all the literature they could find on the association of red meat, fruit, and vegetable consumption to other healthy lifestyle factors and how it pertains to one's health. Oftentimes, and this is something that I really think needs to stop, someone thinks something and they find a study that supports something and they shout from the rooftops, this is the way it is and here's a support and all the while, they don't tell you about the studies that contradict what they are espousing and you get this very isolated or biased and kind of cherry-picked opinion and it doesn't help anybody because the way that we can all learn and become healthier is by looking at all of the evidence, having a discussion about that evidence, and then coming to reasonable conclusions. So a meta-analysis will give you a summary of all that data so that you can make an informed decision on a given issue. So let's pick into a few of the points of the study and again I'll put some of these up here on the screen and read a few of the notes from the study. So intake of red meat was positively associated with BMI or weight, percentage of overweight and obese, so all these kind of go together. Usually if BMI are heavier, you're more prone to be overweight, you're more prone to be obese. Also, red meat consumption was associated with low physical activity and current smoking status or ever being a smoker. And red meat consumption was inversely associated with percentage of non-smokers and high physical activity. So what we're seeing here is that red meat consumption is associated with unhealthy practices and with being overweight. So it's important to factor in. Let's move on. Intake of fruit and vegetables was positively associated with not being a smoker, a higher education level, and a higher level of physical activity. And similar results were found when looking at fruits and vegetables separately. Okay, so the researchers then conclude. In conclusion, the distribution of health risk factors associated with high meat and fruit and vegetable consumption may differ from those of low consumers. Some of the differences may mediate, confound, or modify the relationship between diet and non-communicable disease risk. So essentially what they're saying is when you look at non-communicable disease risk, death, cardiovascular disease, obesity, what have you, that may be associated with, not be caused by the meat consumption itself, but be associated with other unhealthy factors that accompany red meat consumption. So why this is important is because essentially people who eat red meat may be more prone to other unhealthy lifestyle factors. But it doesn't mean that if you're someone, for example, who's going on a paleotype diet, who's not smoking, who's exercising, and who's eating red meat amongst other things like fruits and vegetables, that the red meat is going to be a problem. Oftentimes red meat is vilified and that really may be a mistake. Again, this meta-analysis is showing that the data is pretty incontrovertible, that unfortunately those who have unhealthy lifestyle practices are more prone to eat red meat. Therefore, if you show an increase in cardiovascular disease, cardiovascular episodes, overweight, cancer, what have you, that may be associated not or be caused not by the red meat, but be caused from the smoking, the low physical activity, what have you. Very important to keep that in mind. And a few other thoughts for you, and I guess maybe the one most salient would be to avoid dietary dogma. Any time someone comes at you with an approach that seems to be hard driving, you've got to be vegetarian, you've got to be paleo, you've got to be Mediterranean, I would take a moment to pause for that. Of course, for vegetarians, if you have an ethical reason that you don't want to eat meat, that's fine, and that's its own issue. But from a healthcare perspective, for a vegetarian to argue that you should never eat meat because it's cancer causing or heart disease causing or what have you, there's not really great evidence of support that we've talked in the past about how many trials have shown quite a bit of health benefit from a lower carb or a paleo type diet, even a slight edge in some cardiometabolic and body composition metrics for a lower carb or a paleo type diet. All these diets can be helpful and helpful, but there are some studies actually showing a slight edge for a paleo or a lower carb type of diet, especially when it comes to body composition and cardiovascular disease markers. Also, there's been two studies showing that a paleo diet or a Mediterranean diet can reduce risk of colorectal cancer. It's another commonly used argument in the vegetarian camp. But on the other end of things, there have also been studies done, one most notably in Asian women, that show that they actually lost more weight on a higher carb lower fat diet. And all of these diets tend to improve health from baseline, meaning from no diet at all. So, all these diets can work. It's, I think, important to try to find the diet that works best for you and not get thrown off of working through some of these dietary experiments because a friend of yours watched a documentary that vilified meat and now you're unwilling to try that. Because if you're someone, for example, who has a gut or a metabolism that does better on a lower carb approach and you're pushed off of that approach because of dogma, then all that does is really make it harder for you to get to the dietary recommendations that you need. So, this study is very compelling evidence showing that it may actually be the unhealthy lifestyle factors that accompany red meat consumption that may be the reason for some of the associations to red meat consumption and ill health. So, it may not be the cause, it may be an association, and the true cause of the corollary health detriments that are sometimes associated with red meat consumption may be because of these unhealthy lifestyle practices. In any case, hopefully this information helps you get healthy and get back to your life. Thanks.
