The Dietary Guidelines Advisory Committee Should Be Held Accountable | Carbohydrates Can Kill
By taking a quick glance, the proposed Dietary Guidelines for Americans, 2010 [1] are nothing new but a worse copy of their predecessors. Aside the possible conspiracy that involves politics and favoritism, the guidelines reflect the irresponsibility and naivety of their authors, the Dietary Guidelines Advisory Committee.
Based on the decades old concepts that carbohydrates are a darling and fats are an evil, the current and older versions of Dietary Guidelines have helped both the US and global populations become heavier [2] and increasingly suffer from diseases such as diabetes mellitus, coronary artery disease, arthritis, Alzheimer’s disease, and cancers. [3, 4] At the same time, as a result, the health care cost has steeply risen with no hope of reversal in any time soon. [5] Having known all the facts, the Advisory Committee has committed gross negligence by continuing to recommend a worse version of the old dietary guidelines even with a reduced fat consumption. The act of the Advisory Committee is irresponsible.

Dietary Guidelines 2010 - Must Do No Harm Or Be Overhauled. | Carbohydrates Can Kill
The Dietary Guidelines 2010 Must Do No Harm Or Be Overhauled. | Carbohydrates Can Kill
The report of Dietary Guidelines Advisory Committee on the Dietary Guidelines for Americans, 2010, has stirred up a national controversy and is facing a wave of fierce objections from the public and many health and nutritional experts outside the US Government and the special interest groups.
The controversy is centered on the soundness of these guidelines, which are mostly a copy of the earlier guidelines since 1980, with emphasis on the more consumption of daily calories from carbohydrates and the less from fats especially the saturated fats. [1]
The reliability of these guidelines are further questioned when both the statistics and the layman’s observation concur that the US population has been rapidly growing heavier to that at least six or seven out of every ten adults are either overweight or obese since 1980. [2] Worst of all, the trends in overweight and obesity have also moved into the younger population including toddlers and infants. [3, 4]
Despite that the previous Dietary Guidelines and Food Pyramids have been well publicized, reports such as this, by JD Wright, et al. “Trends in Intake of Energy and Macronutrients—United States, 1971-2000”, points out that, during the study period, the prevalence of obesity in the US increased from 14.5% to 30.9%, the average daily calorie intake increased from 2,450 kcals to 2,618 kcals for men and from 1,543 kcals to 1,877 kcals for women; the percentage of kcals from carbohydrate increased from 42.4% to 49.0% for men and from 45.4% to 52.6% for women; while the percentage of kcals from total fat “ironically decreased’ from 36.9 to 32.8% for men and from 36.1% to 32.8% for women; and the percentage of kcals from saturated fat also “notably decreased” from 13.5% to 10.9% for men and 13.0% to 11.0% for women.
Only a slight decrease from protein was observed. A USDA food consumption survey for the periods between 1989 and 1991, and between 1994 and 1996, indicates the increase of daily calorie intake was caused by higher carbohydrate consumption. The NHANES data for 1971-2000 concur the USDA data, and point out that an increase of 62.4 grams in carbohydrates for women and 67.77 grams for men, while an increase of 6.5 grams in fat for women and a decrease of 5.3 grams for men. Based on these official data, excess consumption in carbohydrate, not in fat, is responsible for the uptrend in obesity for the decades since 1980. [5]

More About Psoriasis
[JEV News, June 24, 2011] Monday, June 20, 2011, Robert Su, M.D. published his weekly article, “Hyperglycemia And Psoriasis.” In his follow-up comments, he wrote, “I finished this article with a humble statement, ‘Future studies are likely to show a high incidence of psoriasis in those who have hyperglycemia, even without a diagnosis of diabetes mellitus, carbohydrate restrictions will offer prevention and treatment for psoriasis and its comorbidities.’ In fact, many individuals’ testimonials have already sworn by the effectiveness of carbohydrate-restriction in preventing and managing psoriasis.” [1]
Dr. Su, author of Carbohydrates Can Kill and podcast host of the Carbohydrates Can Kill Show, explained to JEV News as to why he expected that future studies would support his observations.
He said, “In my continuing literature review in a broad spectrum, I have come to realize the impacts of hyperglycemia on our health, which includes every part of the body, not just certain organ or organs. I can say that I have found a trace or the footprint of hyperglycemia in many diseases, if not all, at this point. Therefore, hyperglycemia surely damages the health of the skin through the immune system, inflammation, even involves the collagen fiber formation.”
He continued, “When I saw the article in the Internal Medicine News [2] that both psoriasis and cardiovascular disorders share the same connection to T-cell, I said to myself, ’Sure. What is new?’ But, the most important key issue is hyperglycemia and inflammation, which are the real cause of disease development. Having known this relationship, I have no problem in expecting future studies would support my observations —- restricting carbohydrates helps prevent and manage psoriasis. In fact, I have already reviewed several personal blogs, in addition to responses from my readers, that restricting carbohydrates improves the symptoms of psoriasis.”
He concluded, “The more studies explore the association between hyperglycemia and disease development, the more will the studies underscore my observations. This is why I can boldly use ‘Carbohydrates Can Kill’ as the title of my book.”

Extracts:
Studying the impact of foods on health has been very difficult. Gathering the dietary information from individuals based on their recollection is not totally reliable. The design of a study, such as the selection of participants and the criteria for the control group and test group(s), may significantly affect its result(s) and conclusion.
Despite that studies have claimed various factors, including fat, infection, inflammation, and others, are carcinogenic, some recent studies have linked carbohydrates to the development of different cancers. Some of the linkages might not be strongly positive. However, the vague linkages are worth taking another look at the causal role of carbohydrates in developing cancers. [4]

"Concurrently, we have witnessed a growing number of cancers. Until recently, fats had been thought responsible for the development of cancers. [13] Now, more evidence shows a link between hyperglycemia and some, if not all, cancers. [14] With better design of research projects, we can expect that this link will become apparent.
Most importantly, we must recognize and bear in mind that excessive carbohydrate intake causes hyperglycemia, diabetes mellitus, and overweight/obesity. [15]

"Despite several studies denied the connection between the incidence of colorectal cancer and glycemic index, glycemic load, and carbohydrates consumption, [7, 8] the data from nearly 1.3 million individuals used in Jee’s study can hardly be ignored.

"Despite several studies denied the connection between the incidence of colorectal cancer and glycemic index, glycemic load, and carbohydrates consumption, [7, 8] the data from nearly 1.3 million individuals used in Jee’s study can hardly be ignored.
In addition, more recent studies supported the link between the risk of colorectal cancer and the consumption of carbohydrates. [9, 10] Gnagnarella P et al summarized, “This comprehensive meta-analysis of GI and GL and cancer risk suggested an overall direct association with colorectal and endometrial cancer.” [11] Barclay AW et al concluded, “The findings support the hypothesis that higher postprandial glycemia is a universal mechanism for disease progression.” [12]
Metabolic Syndrome in Psoriasis - NH&N Survey April 2011
Arch Dermatol -- Prevalence of the Metabolic Syndrome in Psoriasis: Results From the National Health and Nutrition Examination Survey, 2003-2006, April 2011, Love et al. 147 (4): 419
Results The prevalence of the metabolic syndrome was 40% among psoriasis cases and 23% among controls. According to 2008 US census data, the projected number of patients with psoriasis aged 20 to 59 years with the metabolic syndrome was 2.7 million. The univariate and multivariate odds ratios for patients with psoriasis and the metabolic syndrome were 2.16 (95% confidence interval, 1.16 to 4.03) and 1.96 (1.01 to 3.77), respectively. The most common feature of the metabolic syndrome among patients with psoriasis was abdominal obesity, followed by hypertriglyceridemia and low levels of high-density lipoprotein cholesterol.hypertriglyceridemia: http://en.wikipedia.org/wiki/Hypertriglyceridemia
Conclusions The prevalence of the metabolic syndrome is high among individuals with psoriasis. Given the serious complications associated with the metabolic syndrome, this frequent comorbidity should be recognized and taken into account in the long-term treatment of individuals with psoriasis.

"Because psoriasis is an inflammatory disease, and hyperglycemia is inflammatory and proinflammatory, [11] the patients with psoriasis might have had abnormal blood glucose level or hyperglycemia before the disease starts.References:
At this point, psoriasis is indeed a risk factor for several serious diseases, which are related to hyperglycemia and inflammation.
Future studies are likely to show a high incidence of psoriasis in those who have hyperglycemia, even without a diagnosis of diabetes mellitus, carbohydrate restrictions will offer prevention and treatment for psoriasis and its comorbidities."
