Debunking Diet Myths (Pills, Portions, Cal/Protein)

Nutrition Labeling, Better than Portion Sizes

In 2007, a study showed people eat until they’re full and portioning food does not affect calorie intake But now, new research in the Journal of the American Dietetic Association claims consumers associate portion sizes with daily nutrient requirements and not the appropriate amount of food to eat. Among the participants, 33 normal weight people given a randomized meal ranging in size, the portion of food had no impact on fullness or how much total food participants ate. Leading researchers to believe better nutrient labeling would be more helpful to consumers than portion sizes; via FoodNavigatorDon’t worry about portions. Fruits and vegetables are loaded with nutrients, but they’re also packed with fiber! And high-fiber foods, like spinach and beans, are low in calories, eating them fills you up quickly, meaning you can eat a lot and still lose weight. Sure beats plates and Tupperware that tell you how much to eat! Yes, very stupid.
America's Energy Crisis
Is there ever going to be a point where we stop seeing the walls of energy drinks and energy shots at our convenient stores? When I was young there wasn't any Red Bull, Monster or Rock Star drinks. There was only Jolt Cola. Jolt was just like any other cola, except they claimed that it packed more caffeine and more sugar than your average Pepsi. If I was about to head out on a cheerleadng trip I would grab one or two of these for the road. I wasn't much of a coffee drinker back then and Jolt Cola was my pick-me-up when I had to make long trips. The downfall with caffeine and sugar was the crash. I would often get about 6 hours in to the trip and suddenly start to feel the crash. By the time I got home I would be either be wiped clean of any energy I had.
Truck stops used to have the plastic cases next to or behind the counter loaded with little bottles of mini-thins and similar products. They were Ephedrine or Ephedra based stimulants that were not the healthiest stimulant but then again loading up on caffeine and sugar isn't either. People started dying from overuse of ephedra and the United States took action against ephedrine because of the Meth epidemic. That's the reason you had to go to the pharmacy to get anything with ephedrine in it like Sudafed. The most you see in them now are Stackers and other caffeine, guarana and ginseng products,  granted they have just recently made ephedra products available again but you mainly have to buy them online.
These days the energy shots and drinks are still loaded with caffeine, sugar and extra vitamins. We know too much caffeine is bad for your heart and too much sugar is never a good thing for the human body, but what about the vitamins? Vitamins are good, right? That's what we're told as children. People don't know nearly enough about vitamins except for what they might hear on television and rarely do their own research. Naturally if you're told by some random person on TV that B Vitamins are good for you, then you're bound to believe that. Granted, B Vitamins are good for you and B vitamin deficiencies are, well, not good.
The funny thing that people fail to understand when they buy the energy shots like 6 Hour Energy and equivalent products is that most of that vitamin B that is supposed to give you all that energy is just going to waste. If you eat properly you get plenty of vitamin B and there really isn't much need for more. Either way, your body will get rid of any excess water soluble vitamins that it doesn't need and has no need to absorb and pees out. People that take a vitamin B supplement often know how well their body is absorbing it by the color of their urine. Riboflavin or vitamin B2 will tend to make your urine a bright yellow color.
Marketing is an amazing thing because people are so easily manipulated by things that help make day-to-day life more convenient. Fat burning pills, energy supplements and anything else that helps cope with the stress of work or life in general. When you're tired you're tired. There is no other way around it and your body needs rest. No matter how much energy supplements you take, it can not substitute the rejuvenating effect your body gets from a good night sleep. Sometimes you have to slow down, take it easy and let Mother Nature do her thing.

Low-Carb, High-Protein Diets Damage Arteries

Oh, those silly low-carb diets. Will they ever learn! Here’s more bad news for low-carb. A new study in thejournal Proceedings of the National Academy of Sciences found low-carb, high-protein diets damage arties.Diets based on eating lots of meat, fish and cheese, while restricting carbohydrates have grown in popularity in recent years. But the Beth Israel Deaconess Medical Center in the US found such habits caused artery damage in tests on mice.The researchers and independent experts both agreed a balanced diet was the best option. Lead researcher Anthony Rosenzweig said the findings were so concerning to him that he decided to come off the low-carb diet he was following.He added: "Our research suggests that, at least in animals, these diets could be having adverse cardiovascular effects."It appears that a moderate and balanced diet, coupled with regular exercise, is probably best for most people."
And in 2007, a study found low-carb diets, like Atkins, cause long-term damage to blood vessels. Dr. Fuhrman is no fan of high-protein diets, all that saturated fat and insufficient plant nutrients increases risk of heart disease and cancerThe Atkins diet (and other diets rich in animal products and low in fruits and unrefined carbohydrates) is likely to significantly increase a person's risk of colon cancer. Scientific studies show a clear and strong relationship between cancers of the digestive tract, bladder, and prostate with low fruit consumption. What good is a diet that lowers your weight but also dramatically increases your chances of developing cancer?A meat-based, low-fiber diet, like the one Atkins advocates, includes little or no fruit, no starchy vegetables, and no whole grains. Following Atkin's recommendations could more than double your risk of certain cancers, especially meat-sensitive cancers, such as epithelial cancers of the respiratory tract.1 For example, a study conducted by the National Cancer Institute looked at lung cancer in nonsmoking women so that smoking would not be a major variable. Researchers found that the relative risk of lung cancer was six times greater in women in the highest fifth of saturated-fat consumption than those in the lowest fifth.
When Dr. Fuhrman was asked to comment on this study. He chuckled at the news, saying, “This study definitely proves once and for all that mice should not be eating the Atkins diet. They should get Jenny Craig. Furthermore, vegetables make pigs fat, so maybe we shouldn't eat them either.”
