Inhaltsangabe

Unit 1: Dietary Guidelines
Issue: Are Dietary Guidelines Ethical and User Friendly?
YES: Mark Hay, from "What Americans Can Learn from the New Dutch Dietary
Guidelines." The Daily Good (2016)
NO: Michiel Korthals, from "Ethics of Dietary Guidelines: Nutrients,
Processes and Meals," Journal of Agricultural and Environmental Ethics
(2017)
Journalist Hay applauds the new Dutch Dietary Guidelines and their
recommendations to cut back on animal foods-no more than one serving of
fish per week and no processed meat. These recommendations are based
largely on environmental sustainability. Professor Korthals groups the
Dutch and American dietary guidelines in the category of focusing on
nutrients and foods and points out the recommendations are influenced by
groups from the sugar, beef, egg, and dairy industries. He criticizes both
countries' belief that they have "the final truth on the healthiness of
nutrients, and they heap scorn on diet gurus".
Issue: Will the U.S. Government's Dietary Guidance Improve Health?
YES: 2015 Dietary Guidelines Advisory Committee, from "Executive Summary,"
Scientific Report of the 2015 Dietary Guidelines Advisory Committee (2015)
NO: Adele Hite, from "Healthy Nation Coalition's Letter to the Secretaries
of Health and Human Services and the United States Department of
Agriculture Regarding the Scientific Report of the 2015 Dietary Guidelines
Advisory Committee," Healthy Nation Coalition (2015)
The 2015 DGAC acknowledges that the average American has not followed
dietary recommendations to reduce consumption of saturated fat, sodium, and
sugar and continues to recommend for reductions in the three nutrients to
improve health in Americans. They also stress the importance of eating an
overall healthy diet and support food-based dietary guidelines with
emphasis on fruits, vegetables, and whole grains. Adele Hite believes that
the DGAC report will "perpetuate the same ineffective federal nutrition
guidance that has persisted for nearly four decades but has not achieved
positive health outcomes for the American public." He cites studies that
claim reductions in saturated fat, cholesterol, and sodium, while
increasing starch and vegetable oils actually increase the risk for chronic
diseases. Hite, the Healthy Nation Coalition director and co-founder,
claims that "Millions of taxpayer dollars are spent on policies and
practices related to guidance whose scientific foundation has yet to be
established."
Issue: Should Dietary Guidelines Stress Less Added Sugars?
YES: Barbara E. Millen, from "Part D. Chapter 6: Cross-Cutting Topics of
Public Health Importance: Added Sugars and Low-Calorie Sweeteners,"
Scientific Report of the 2015 Dietary Guidelines Advisory Committee (2015)
NO: Andrew C. Briscoe III and P. Courtney Gaine, from "The Sugar
Association's Letter Written in Response to Scientific Report of the 2015
Dietary Guidelines Advisory Committee," The Sugar Association (2015)
The DGAC concludes that there is strong evidence that diets high in added
sugars are associated with overweight, obesity, and type 2 diabetes and
moderate evidence that sugars are linked to dental caries, hypertension,
stroke, and cardiovascular disease. They call for an upper limit (UL) of 10
percent of energy to come from added sugars in the diet. They also
recommend that additional studies need to be conducted on the roles of
sugars and various health conditions. The Sugar Association, whose mission
is to "monitor nutrition science . . . to provide science-based information
. . . and to ensure that Federal nutrition and food policy regarding sugar
is based on the preponderance of scientific evidence," asks the Secretaries
of HHS and USDA to continue the same advice about added sugars that was in
the 2010 DGA. The 2010 advice is to simply reduce intake of calories from
added sugars and limit refined grains that contain added sugars, without a
specific upper limit recommendation based on the percent of energy.
Unit 2: Nutrition and Health
Issue: Is Nutrigenomics Useful in Weight Loss?
YES: David C. Merritt, Joseph Jamnik, and Ahmed El-Sohemy, from "FTO
Genotype, Dietary Protein Intake, and Body Weight in a Multiethnic
Population of Young Adults: A Cross-Sectional Study," Genes and Nutrition
(2018)
NO: Caitlin Dow, from "Personalized Nutrition: Do You Need a Just-for-Me
Diet?" Nutrition Action Healthletter (2018)
The race to identify nutrition-related genes has been underway since the
human genome was sequenced in 2003. One of the first identified was the fat
mass and obesity-associated (FTO) gene. As early as 2007, reports have
linked certain variants of this gene to a variety nutrient/weight-loss
diets. Merritt and his team support this belief and conclude that high
protein intake results in greater weight loss among individuals with
certain FTO variants. Caitlin Dow disagrees and points out that results of
her genetic testing found two high-risk variants of the FTO gene, but she
is not overweight or obese. She also concludes that at least 97 gene
variants have been linked to obesity, but only account for 3 percent of
weight differences among the population.
Issue: Do Probiotics and Prebiotics Promote Health?
YES: Rout George Kerry et al., from "Benefaction of Probiotics for Human
Health: A Review," Journal of Food and Drug Analysis (2018)
NO: Matt Wood, from "Do Probiotics Work?" Science Life (2014)
Rout George Kerry leads the group of researchers from India and Korea to
describe the differences between and sources of probiotics, prebiotics and
synbiotics. They review the latest research related to use of probiotics to
treat diarrhea, obesity, diabetes, IBS and cancer. Matt Wood discusses what
the scientific studies show about the various biotics but points out some
negative effects of prebiotics and stresses that there is only a very short
list of probiotics shown to actually be beneficial to health.
Issue: Does Eating Beans Improve Health?
YES: Donna M. Winham et al., from "Arizona Registered Dietitians Show Gaps
in Knowledge of Bean Health Benefits," Nutrients (2018)
NO: Joseph Mercola, from "The Case Against Beans and Other Foods Containing
Toxic Lectins," Mercola (2018)
Winham and her colleagues claim that beans are nutrient-dense and emphasize
the benefits that beans provide to humans have been recognized for many
years. They point out several epidemiological studies that indicate
consuming high amounts of beans is associated with greater longevity. The
focus of their article is describing the knowledge that Registered
Dietitians Nutritionist have about beans, legumes, and pulses. Mercola
warns that beans contain lectin, a substance known to cause a variety of
health problems. He points out that lectins cause the most problems to
individuals who have thyroid dysfunction, arthritis, diabetes or heart
disease.
Issue: Is Modern Wheat Unhealthy?
YES: Kris Gunnars, from "Modern Wheat-Old Diet Staple Turned into a Modern
Health Nightmare," Authority Nutrition (2014)
NO: The National Wheat Improvement Committee, from "Wheat Improvement: The
Truth Unveiled," National Association of Wheat Growers (2013)
Kris Gunnars claims that there are profound genetic changes in modern wheat
and that it is processed differently than wheat grown in earlier times. He
describes how the new wheat is the root of a variety of health problems.
Members of the National Wheat Improvement Committee point out why modern
wheat is not the cause of celiac disease or gluten sensitivity. And that
today's wheat has less gluten protein but improved gluten function than
historical wheat.
Issue: Does Coconut Oil Provide Health Benefits?
YES: The Coconut Research Center, from "The Coconut Oil Miracle: Where Is
the Evidence?" Coconut Research Center (2015)
NO: William A. Correll, from "FDA Warning Letter to Carrington Farms,"
Office of Compliance, Center for Food Safety and Applied Nutrition, Food
and Drug Administration (2015)
Authors of the Coconut Research Center website boast of the various health
benefits of coconut oil related to seizures, dementia, ALS and
cardiovascular disease. They describe the number of studies available
through a PubMed search that support the health benefits of coconut oil and
the medium-chain fatty acids found in the oil. After reviewing claims that
Carrington Farms includes on the labels of coconut oil, William Correll,
FDA Director Office of Compliance, Center for Food Safety and Applied
Nutrition, issues a warning letter to the company pointing out the
therapeutic claims on their website about coconut oil classify it as a
drug, not a food, and points out other violations on the labels.
Issue: Are Artificial Sweeteners Harmful?
YES: Joseph Mercola, from "Reconfirmed: Artificial Sweeteners Make You Fat
and Sick" Mercola (2018)
NO: Szimonetta Lohner, Ingrid Toews, and Joerg J. Meerpohl, from "Health
Outcomes of Non-nutritive Sweeteners: Analysis of the Research Landscape"
Nutrition Journal (2017)
Mercola points out that many people mistakenly think that
artificially-sweetened products are a healthier option as they reduce
calories, but he claims that "nothing could be further from the truth." He
outlines how they increase the risk of diabetes, obesity, cardiovascular
disease, stroke and Alzheimer's disease. After reviewing 420 studies,
Lohner and colleagues conclude that there is no conclusive evidence showing
that non-nutritive sweeteners are harmful.
Issue: Is Breastfeeding Inevitably Best for Healthy Development?
YES: U.S. Department of Health and Human Services, from The Surgeon
General's Call to Action to Support Breastfeeding, Office of the Surgeon
General (2011)
NO: Courtney Jung, from "Overselling Breastfeeding," The New York Times
(2015)
Breastfeeding children is both a personal and societal issue. As part of a
broad mandate to advocate for public health, the U.S. Surgeon General cites
numerous benefits of breastfeeding as part of "call to action" oriented
toward increasing the practice among new mothers. However, Courtney Jung's
article provides a cautionary view of these benefits. She describes the
zealousness with which Americans pursue breastfeeding, possibly to the
detriment of the mother's health and with limited benefits for the child.
Jung also describes the economic motivation for encouraging breastfeeding.
She does not discourage it, but, rather invites readers to examine
parenting practices with a critical lens.
Unit 3: Our Food Supply
Issue: Are Organic Diets Environmentally Sustainable?
YES: Carola Strassner et al., from "How the Organic Food System Supports
Sustainable Diets and Translates These into Practice," Frontiers in
Nutrition (2015)
NO: Henry I. Miller, from "How College Students Are Being Misled About
'Sustainable' Agriculture," National Review (2017)
Strasser and her European colleagues explain why the organic food system is
a good example for developing a sustainable diet. They describe the organic
farming movement from a global perspective and outline how it increases
yield, improves soil fertility and water-holding capacity. Miller agrees
that sustainability is a positive step for humanity but claims that using
organic farming practices is not the way to achieve it. He thinks that
college students are being brainwashed about the superiority of organic
diets while ignoring the negative (and unsustainable) aspects of organic
farming.
Issue: Does the World Need Genetically Modified Foods?
YES: William Saletan, from "Unhealthy Fixation: The War against Genetically
Modified Organisms Is Full of Fearmongering, Errors, and Fraud. Labeling
Them Will Not Make You Safer," Slate (2015)
NO: Claire Robinson, from "Lessons in Critical Thinking and William
Saletan-Part 1," GMWatch (2015)
William Saletan defends biotechnology used in genetically modifying foods
and believes they bring many advantages and help ensure a safe food supply.
He says the case against genetic modification is full of errors, fallacies,
misconceptions, misrepresentations and lies. GMWatch editor Claire
Robinson, and co-author of the free online book GM Myths and Truths, points
out the fallacies of Saletan's defense of GM foods in her rebuttal to his
article. She concludes that Saletan's critical thinking skills deserve an
"F" for "Fail."
Issue: Should All Trans Fat Be Banned in Processed Foods?
YES: Food and Drug Administration, from "Final Determination Regarding
Partially Hydrogenated Oils," Food and Drug Administration (2015)
NO: The Grocery Manufacturers Association, from "A Petition to the Food and
Drug Administration (FDA) about Partially Hydrogenated Vegetable Oils
(PHOs)," Center for Science in the Public Interest (2015)
In June 2015, the Food and Drug Administration issued the final
determination that partially hydrogenated oils (PHOs) are no longer on the
GRAS list because they are not "generally considered as safe." In effect,
this means that trans fats are banned from foods because PHOs are the main
source of trans fat. The FDA announced that PHOs must be removed from
processed foods by June 2018. The Grocery Manufacturers Association filed a
detailed petition outlining the safety of PHOs and requesting that low
levels of PHOs be allowed in certain processed foods.
Issue: Are Interesterified (IE) Fats as Bad as Trans Fats?
YES: Gregory D. Sloop, Joseph J. Weidman, and John A. St. Cyr, from
"Perspective: Interesterified Triglycerides, The Recent Increase in Deaths
from Heart Disease, and Elevated Blood Viscosity," Therapeutic Advances in
Cardiovascular Disease (2018)
NO: Andreina Alfieri et al., from "Effects of Plant Oil Interesterified
Triacylglycerols on Lipemia and Human Health," International Journal of
Molecular Science (2018)
Gregory Sloop's team believes that the new IE fats are as bad as trans fats
and may be the cause of Increasing the risk cardiovascular deaths since
2011. Andreina Alfieri's group describes the differences in the digestion,
absorption, and metabolism of natural and interesterified fats. They
suggest that types of fatty acids found in IE fats influence effects on
health status and that some types of EI may actually reduce cardiovascular
disease risk.
Unit 4: Nutrition and Food Policy
Issue: Should Clean Labels Be Used on Foods?
YES: Lisa Lefferts, from "Clean Labels: Public Relations or Public Health?"
Center for Health in the Public Interest (2017)
NO: Nadia Berenstein, from "Clean Label's Dirty Little Secret," The New
Food Economy (2018)
Although there is no legal definition, the "clean label" concept generally
implies that processed foods have short ingredients lists and no artificial
ingredients. Lefferts reports that consumers are demanding to know if
products are free of artificial and potentially unsafe ingredients, and
that many chain grocery stores and restaurants are promoting clean foods.
She believes their efforts are in the right direction, and that more should
adopt clean label programs. Nadia Berenstein unveils the secrets behind the
clean label movement and questions if the public realizes the changes that
removing additives will have on the foods they have grown to enjoy. She
also wonders if "clean foods" are really better than standard processed
foods.
Issue: Is Vegetarianism the Future of Halal Eating?
YES: Febe Armanios and Bogaç Ergene, from "For Many Muslim Grocery
Shoppers, a Shifting Definition of Halal," The Conversation (2018)
NO: Adam Withnall, from "Why Is Halal Meat So Controversial?" The Week UK
(2014)
Armanios and Ergene trace the history of Islamic eating and describe what
tayyib-halal foods are, including how meat and poultry are killed based on
Quranic rules. They discuss the growing evidence that veganism is probably
the food pattern most consistent with the Prophet Muhammad's lifestyle and
that many younger Muslims are shifting to ethically sourced foods and
veganism. In contrast, Withnall points out the increase in global sales of
halal meats, describes the slaughter process, and speculates the amount of
pain caused to the animals during slaughter.
Issue: Should Fluoridated Water Be Banned?
YES: Michael Connett, from "Citizen Petition Under Section 21 of TSCA:
Regarding the Neurotoxic Risks Posed by Fluoride Chemicals in Drinking
Water," Environmental Protection Agency (2016)
NO: Environmental Protection Agency (EPA), from "Fluoride Chemicals in
Drinking Water; TSCA Section 21 Petition; Reasons for Agency Response," The
Federal Register (2017)
Michael Connett leads concerned citizens in their petition to the EPA to
remove fluoride from public drinking water. They claim that fluoride causes
neurotoxic damage and include over 180 studies that support fluoride's
neurotoxicity. They point out that fluoride's benefit to dental health is
from topical application to teeth, not by swallowing it in drinking water.
The EPA denies the petition to remove fluoride from public water supplies
concluding there is lack of scientific studies showing that people in the
United States have suffered brain damage or other problems from drinking
fluoridated water.
Issue: Do Diet Sodas Aid in Weight Loss?
YES: William Hudson, from "Diet Soda Helps Weight Loss, Industry-funded
Study Finds," CNN (2014)
NO: Stephanie Bucklin, from "Why Diet Soda Could Actually Prevent You from
Losing Weight," The Huffington Post (2016)
CNN Medical Producer William Hudson reports that studies show that diet
soda drinkers are likely to lose more weight than water drinkers. Writer
Stephanie Bucklin argues that research indicates that diet soda may
actually hinder weight loss efforts.
Issue: Should FDA Revoke Soy's Health Claim?
YES: Joseph Mercola, from "Soy-Health Food or Not?" Mercola (2017)
NO: Matthew Ruscigno, from "Soy Under Fire," Today's Dietitian (2017)
Dr. Mercola ha s long warned against eating unfermented soy and points out
the many negative aspects of soy products. He welcomes FDA's efforts to
revoke the health claim about soy reducing the risk of heart disease.
Dietitian Matthew Ruscigno disagrees and concludes that average individuals
who are at risk of heart disease "would most likely benefit from adding soy
foods to their diets."
Issue: Do Pesticides Cause Birth Defects and Other Health Problems?
YES: Christopher Pala, from "Pesticides in Paradise: Hawaii's Spike in
Birth Defects Puts Focus on GM Crops," The Guardian (2015)
NO: Environmental Protection Agency, from "Food and Pesticides,"
Environmental Protection Agency (2015)
Christopher Pala reports an increase in birth defects and pediatric
morbidity in areas of Hawaii where high levels of pesticides are used for
testing growth of GMO corn. He also describes the steps some Hawaiians are
taking to restrict the testing of pesticides in Hawaii. The Environmental
Protection Agency claims that American agricultural products are rigorously
tested, and the pesticide residue levels cause no health problems,
especially among children.
