Carbohydrate Confusion Q & A (from the Potato industry)

http://healthypotato.com/carbo.htm Carbohydrate Confusion Q & A Q: What role do carbohydrates play in an overall healthy diet? A: Dietary carbohydrates that are not required immediately for energy are converted to glycogen, the only storage form of carbohydrate in the human body, and stored as the most readily available energy (calories) in muscles and in the liver. Some carbohydrates, which are used as glucose in the body, are necessary for the body to be able to "burn" or oxidize fat (in the form of fatty acids) for energy, the body's system for using fat for energy (calories). If no carbohydrate is available for this and for other carbohydrate needs of the body, protein, in the form of amino acids, is stripped of nitrogen and the carbon skeleton is converted to glucose in the liver. This is a life-preserving mechanism, however, it takes away from the body's valuable protein stores. Ann M. Coulston, M.S., R.D., F.A.D.A. Q: What does the average person need to know about carbohydrates in their diet? A: Carbohydrates are the primary macronutrient fuel source for the body. While protein and fat can be utilized as fuel, carbohydrates are most readily converted into glucose in the blood. For a balanced diet, carbohydrates should supply slightly over half of one's calories for the day. Carbohydrates often are referred to as "simple" or "complex". Simple carbohydrates are sugars, for example: fructose (in fruit), sucrose (table sugar), and lactose (in milk). Complex carbohydrates are starches, found in foods like potatoes and other vegetables, breads, and cereals. Whole grain foods, fruits, vegetables, and legumes (dried beans and peas) should be the source of most of the carbohydrates in the diet. Mindy Hermann, M.B.A., R.D. Q: What happens when you restrict your carbohydrate intake? What vitamins and nutrients are lost? A: If you restrict carbohydrate intake severely, you can push the body into ketosis, an abnormal metabolic state. The claim is that as a result, calories are "lost" in the urine as a result of the incomplete metabolism of fat. In fact, there have been no studies that adequately address the question of how many calories are actually "lost," but experts believe that it is too few to have a significant effect on weight. The nutrient that is found uniquely in vegetables and fruits is vitamin C. Plant foods are also the unique sources of fiber, and they provide an abundance of antioxidant compounds, whose role in diet and health is under active investigation. Jeanne Goldberg, Ph.D., R.D. Q: Why do people lose weight on low carbohydrate diets? A: There are two reasons that people lose weight on low carbohydrate diets. In the short term, with drastic dietary restriction of carbohydrate, the body turns to stored glycogen as a source of carbohydrate. Since glycogen is stored with water, the depletion of these stores is associated with considerable fluid loss early in the regimen. The weight lost is regained as soon as the individual resumes eating carbohydrate. The second reason relates to the fact that individuals who continue to follow these diets actually consume fewer calories than they burn, either because they experience a loss of appetite, possibly related to the ketosis or because they become bored with the diet and simply begin to eat smaller quantities of food. Jeanne Goldberg, Ph.D., R.D. Q: Why should low carbohydrate diets be avoided? A: The body is designed to burn, for energy, carbohydrate first and foremost. Although the body can burn fatty acids (stored in the adipose tissue), physiologically this is a secondary mechanism after our limited carbohydrate stores, in the form of glycogen, have been partially expended. The minimum amount of carbohydrate needed to ensure available glucose for the brain to function normally is 130 g/day for adults and children. However, most of us consume 200 to 300 g each day depending on our body size. In addition to the minimum requirement for normal body metabolism, many key vitamins are found in the food supply associated with carbohydrate sources, such as vitamin C, most B vitamins, and dietary fiber, which is helpful for gastrointestinal regulation. Ann M. Coulston, M.S., R.D., F.A.D.A. Q: What are the disadvantages of diets too high in protein and fat? A: In addition to the fact that these diets are typically very low in fiber, contain little if any vitamin C, and antioxidants found in plant foods, these diets tend to be high in saturated fat. Decades of research have demonstrated that this is a major factor in elevated serum cholesterol and in the cardiovascular disease associated with it. Long-term consumption of large amounts of fat has also been associated with several types of cancers. Beyond that, these diets do not provide long-term solutions to weight control. Jeanne Goldberg, Ph.D., R.D. Q: What factors contribute to people becoming dehydrated when they are dieting? A: The number one source of dehydration during dieting is consuming a high protein diet. The metabolism of dietary protein generates by-products that must be filtered out through the kidneys. This filtration is accompanied by additional fluid necessary to dilute these waste products of protein metabolism. Dehydration also can ensue from the breakdown of muscle tissue that accompanies dieting. Low calorie diets, as well as weight loss diets that are low in carbohydrates, are associated with greater loss of muscle tissue. Mindy Hermann, M.B.A., R.D. Q: What is the safest way to loose weight for the long term? A: Probably the only method of weight loss that can be considered "unsafe" is long-term fasting (consuming nothing by mouth). However, for some people reducing caloric intake by decreasing carbohydrate or fat in the diet may be unhealthy. The "safest" method and the method that, theoretically, should produce desired long-term weight loss is to decrease portion size of all foods. This requires self-discipline, which can be extremely difficult in many settings. For example, to decrease portion sizes, one should avoid settings that encourage over-consumption, such as "all-you-can-eat" settings and restaurants known to serve large portions. Ann M. Coulston, M.S., R.D., F.A.D.A. Q: How should the average person evaluate the merits of a particular diet plan before implementing? A: A diet plan should not exclude any one food group or particular food. Nor should it severely limit any food with the justification that that food is responsible for overweight. The diet plan also should not promise dramatic weight loss. Foods to be included in a sensible weight loss plan are grain foods (at least one per meal), fruits, vegetables, dairy products (for calcium and protein), and protein foods like beef, poultry, fish, eggs, and vegetable sources of protein like legumes and nuts. No single food group should be touted as being unlimited or allowed in unusually large quantities. Fat need not be strictly limited, except to the extent that it contributes to total calories, and a person trying to lose weight needs to limit total calories. Mindy Hermann, M.B.A., R.D. Q: A friend of mine has been on a low-carbohydrate, high-protein diet. I'm confused. Is this a healthy way to lose weight? A: With the current popularity of diets that promote protein imbalance while limiting carbohydrates, it's easy to become confused and wonder if these weight loss claims are really valid. Many high-protein, low carbohydrate dieters will lose weight in the short-term, mainly because these diets restrict calories. The basic premise of high-protein, low-carbohydrate diets is to avoid or limit carbohydrates, while loading up on protein and fat. Many of these fad diets recommend avoiding rice and pasta, as well as vegetables such as potatoes, carrots, peas, corn and squash and fruits, such as bananas, apples and raisins. Diets that severely limit carbohydrates have possible side effects, including dehydration, nausea and fatigue. These diets also tend to be low in nutrients such as vitamin C and can accelerate calcium loss from your body. In the long-term, when carbohydrates are restricted, the accompanying lack of dietary fiber can lead to serious health risks such as diverticulitis, inflammation of the colon and increased risk of cancer. The American College of Sports Medicine, the American Dietetic Association, the Women's Sports Foundation and the Cooper Institute for Aerobics Research issued a joint statement that high-protein, low-carbohydrate diets are not the answer for weight loss. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= *** Usenet.com - The #1 Usenet Newsgroup Service on The Planet! *** http://www.usenet.com Unlimited Download - 19 Seperate Servers - 90,000 groups - Uncensored -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= |

Carbohydrate Confusion Q & A (from the Potato industry)

Q: What is the safest way to loose weight for the long term? The "safest" method and the method that, theoretically, should produce desired long-term weight loss is to decrease portion size of all foods. This requires self-discipline, which can be extremely difficult in many settings. For example, to decrease portion sizes, one should avoid settings that encourage over- consumption, such as "all-you-can-eat" settings and restaurants known to serve large portions. Translation: You have no choice but to cut back portions and calories to starvation levels, experience chronic hunger and lethargy and irritability and then use super-human "will-power" to override the body's attempt to get you to eat more. If you can't do this then you are a fat lazy slob or its McDonald's fault but it is not the carbos fault -- that we are absolutely sure of, so be sure to have a potato chip on your "healthy" diet. No thanks! Regards, David |

"Roger Zoul" wrote in message ... I think there is something wrong with it when they lie and spread misinformation to do so.... In theory I agree. But this is an imperfect world and consumers are subjected to a daily barrage of lies, half lies, pseudo science and the rest of it to support the aims of those who are dishing it out. The important thing, IMO, is to look at what would best serve the interests of the speaker (or writer) and review what is said with this in mind. Here we have potato people talking about carbs; what message would you expect? At least they say who they are; I think the worst are people who look like experts, Dr. Susan Jebb (sp?) for example, who are actually shills for some product or point of view. Caveat emptor, as usual. |

The second reason relates to the fact that individuals who continue to follow these diets actually consume fewer calories than they burn, either because they experience a loss of appetite, possibly related to the ketosis or because they become bored with the diet and simply begin to eat smaller quantities of food. Jeanne Goldberg, Ph.D., R.D. ROFLMAO - this has got to be one of the funniest statements I've ever read. I can't say I've ever known anyone who ate _less_ out of boredom, of any kind - whether dietary boredom or life boredom. If anything, people bored in life tend to eat more, and people bored with a diet tend to go off it. Q: What are the disadvantages of diets too high in protein and fat? A: In addition to the fact that these diets are typically very low in fiber, Only if you let them be - there is plenty of fiber in avocado, nuts, seeds, etc. And you can always supplement it too. contain little if any vitamin C, and antioxidants found in plant foods, Strawberries have quite a bit of vitamin C, as do multivitamins. Leafy greens are very high in antioxidants, as is broccoli. Why do these people always ignore the fact that LC is not a *no* carb WOE, and that vegetables are both included and encouraged? these diets tend to be high in saturated fat. Decades of research have demonstrated that this is a major factor in elevated serum cholesterol and in the cardiovascular disease associated with it. Really - so why is it that people's serum cholesterol tends to go _down_ on LC diets? Beyond that, these diets do not provide long-term solutions to weight control. Jeanne Goldberg, Ph.D., R.D. sarcasm Shhh, don't tell anyone that, Dr. Goldberg. Apparently those who have found long-term success are merely deluding themselves that it has really worked. We wouldn't want to wake them up from their happy dream of finally being in control of their weight. /sarcasm And of course this is also not taking into account that NO diet provides a long-term solution to weight control - if you don't stick with it long-term. What a silly article, and chock-full of all the typical misinformation (lack of nutrients, brain has to have 130g carbs to function, all the weight lost is water, etc). |

Well, since they have nothing else, they look for a strawman so they can knock it down. |
