200% of the bare minimum is still not a whole lot. And while I agree that quality may be an issue (ie: grass fed beef is preferable to grain fed), it's not nearly as problematic as the general public believes. Again, the research on diets heavy in meat isn't open and shut unless you only look at poorly designed and controlled observational studies, and even then, I've yet to see a meta-analysis of the observational studies out there which showed anything resembling a consistent and reproducible result from them. And once you start looking beyond those into clinical and intervention studies where the variables are much more strictly controlled and tracked, the old lipid hypothesis (which your bringing in fat content tells me you subscribe to) which tells us that meat is making everyone fat and sick completely falls apart.acosn said:The average American gets 200% of their daily allotment of protein.
Most of this comes from meat.
The research on meat heavy diets- especially the lower quality meats that tend to creep up most often because of their lower price points- is pretty much open and shut. What's more, the most prized meats are valued for their marbling- which is to say their fat content.
In fact, despite eating less meat than the population did 50-100 years ago, obesity and heart disease rates continue to rise.
The USDA is a political organization first and foremost. And like Health Canada and any other government organization which has purported to be an expert on human diet, they've been more than willing over the decades to bend either to the will of lobbyists, or whatever politicians are running the show at the time. Several decades ago, despite many of the best scientists at the time telling George McGovern and his committee on the subject that though they weren't sure what was causing heart disease, it probably wasn't fat, he ignored them and recommended low fat diets because he couldn't see how anything but eating fat could clog arteries with fat. It's worth pointing out that he wasn't a scientist but a politician with no expertise in the matter. His subsequent report on dietary guidelines was also drafted by an assistant who was a vegetarian.TomWiley said:Then I guess you must know better than the "supposed experts" at USDA
When you say ADA are we referring to the American Dietetic Association or the American Diabetes Association? Not that it much matters since both make recommendations fairly in line with each other, and both are quite ignorant of reality.because according to both USDA and the ADA, vegitariens are at lower risk of developing; "Heart disease, Colorectal, ovarian, and breast cancers, Diabetes, Obesity abd Hypertension", and they live longer and healthier lives than their fellow meat eaters.
First, heart disease isn't caused by eating meat. The best current indicator of heart disease risk is the level of small LDL cholesterol particles in the blood. Note that there is more than one kind of LDL so I am not saying all LDL cholesterol is bad. The larger particles are actually very good to have in the blood stream. But the smaller kind are the ones that invade the walls of damaged blood vessels and cause arteries to narrow. Except these particles aren't ingested through food intake. The body produces them on its own through a process called glycation when blood sugar is frequently and repeatedly elevated. This doesn't happen as a result of eating meat, but rather an over consumption of carbs, particularly carbs like sugar and wheat which have the largest impact on blood sugar. These diets are also made worse by the fact that they promote inflammation which damages the artery walls in the first place. Low carb diets with plenty of meat and fat have actually shown to improve levels of small LDL particles, and to not produce the inflammatory effects that those other carbs do.
On the topic of cancer, I've yet to see anything other than an observational study show a link. Observational studies can't be used to show cause and effect by design (not that that stops these organizations from using them as proof of their claims), and none that I've seen have shown more than a miniscule change in the absolute cancer rates (though they try to make the risk seem larger by throwing out numbers like "200% increase in cancer risk" even though a 200% increase from next to nothing is still next to nothing) and these studies tend to have such strange groupings of food in different categories and other confounding variables as to make them absolutely useless for anything more than developing a hypothesis for further and more detailed testing. To use them as the basis for dietary advice is not only disingenuous but outright unprofessional.
Claims of avoiding meat reducing risk of obesity and diabetes are perhaps the most laughable of all to anyone who understands even at the most basic of levels how the body stores fat and how the pancreas is damaged causing type 2 diabetes. The hormone most directly responsible for fat storage is insulin produced as needed by the pancreas. When blood sugar increases, insulin sends signals to the muscle tissue to burn it for fuel. The trouble is that muscle tissue can only burn it so quickly. When the glucose spike is too much for muscle tissue to efficiently handle, insulin will also trigger the storage of glucose in fat cells. The issue comes, once again, when blood glucose is frequently and repeatedly spiked (such as when someone consumes a lot of sugary soda or grains). Again, muscle tissue can only burn glucose so quickly, but if it's spiked to an extremely high level, it has to be dealt with sooner rather than later as high blood sugar is generally quite bad for us (ie: it could kill you). In these cases, the body has to store much of it to get it out of the blood stream, and the pancreas has to produce more insulin to deal with the spike. It gets worse though because in the long run if this continues, many people will have their muscle tissue become insulin resistant, requiring ever larger amounts of insulin to get it to burn the same amount of glucose, meaning more gets stored as fat. And in the long run, this constant strain on the pancreas to produce more and more insulin is what causes permanent damage and eventually type 2 diabetes.
So sorry, but not eating meat isn't going to reduce your risk of heart disease, obesity, or diabetes. But if you pass on the sugary drinks and cereal for breakfast you'll be off to a great start.
I disagree. I'd argue that many of the people who eat a vegetarian diet go that route for health reasons. By the same token, they likely stop drinking soda and eating a lot of sugar, while eating more fruit and vegetables instead of the large quantities of grains that the average person eats, in part due to their need to supplement for missing protein and fats from other sources. It's more likely that they simply have their blood sugar more under control than someone who regularly gets a sugary soda to go along with that bread filled burger and super sized fries (with lot's of starch which is also bad for blood sugar) they bought for lunch at McDonald's. It's not so much that meat is bad for you. Just that meat has been demonized for so long that many of the people who still eat it also happen to not give a shit and eat other things which are actually bad for them.And this is simply because they eat less than meat than we do.
I'll be sure to tell my immune system which requires saturated fat to function optimally and my brain which is mostly made of saturated fat that they don't need meat and the fat that comes with it. Never mind the fact that I literally suffer from depression if I eat a low fat diet (an effect which is very real and reproducible), or that I'm not alone on that one. I've spoken with a number of people who used to be vegetarians, suffered from depression, then saw their symptoms disappear when they changed their diet and included more animal fats.So no, it seems like we don't need more meat to stay healthy. If anything we need to eat less meat and consume more vegetarian alternatives.
We evolved to eat meat and dietary fat, including saturated fat. A lot more than most people actually eat now. Instead we've replaced these foods which we adapted over literal millenia to eat with an amount of carbohydrates which wasn't available to humans in most parts of the world until a few thousand years ago, and even more so now. It's no surprise that when we started eating diets completely foreign to us that we started having problems.
