War in the series of food science, it highlights issues of food security and nutrition that are often misinformed
In the spirit of exploring the National Geographic of the War of Science , the FACTS Network (Defenders food, bisphenol-A and low-calorie sweeteners. This is what the experts had to say about science in these issues and why they think these issues are so often misreported, communication through Science) of the IFIC Foundation – An expert, interactive scientific, global network health and food advocates formed to combat the rising tide of misleading advice, statistics and scare tactics – published a three – part series on the blog Food Insight War of Food Science. Each installment featured experts on food security and nutrition who share their views on three commonly misinformed topics: corrections rapid weight loss
1. Quick fixes for weight loss
Red FACTS (FACTS): How does science enters the discussion of Pastillas para perder Peso Rapido? Where it is absent?
Hollie Raynor, PhD, RD, LDN, Associate Professor and Director of Nutrition and Public Health, University of Tennessee, Knoxville: Virtually all studies of the National Institutes of Health (NIH) have demonstrated success at 6 months or more, the use of a combination of diet, physical activity and behavior strategies.Such interventions are called lifestyle interventions. Produce a degree of weight loss improves health outcomes, such as prevention of type 2 diabetes Several professional organizations have used this research to provide recommendations for the treatment of obesity. However, this evidence seems to be absent in the secular media as press reports and magazines .
FACTS: To be scientifically substantiated help or affect the weight loss programs are popular among consumers?
Julie Schwartz, MS, RDN, CSSD, LD, ACSM-HFS, Coach Certificate of Health: I do not think it helps or harms. However, seeing a science – based that has been well researched against models that are sexy and weight loss “easy” plan, consumers tend to keep their emotions. I think there is a strong segment of people who are tired of trends and want lasting results, you want help to make changes that lead to lasting change in weight and to learn behaviors that lead to maintenance.
FACTS: If you will develop the perfect media coverage, scientifically based, to control weight loss, how would it be?
HR: The stories say that weight loss occurs due to the realization of a negative energy balance and weight maintenance is due to a balance between energy consumption and energy expenditure. Point.
2. Bisphenol-A (BPA)
Bisphenol-A (BPA) is used in food and beverage containers to protect food from contamination that can cause foodborne illness.
FACTS: What we know about bisphenol A and any impact on our bodies?
Henry Chin, PhD, Food Safety & Risk Communication Expert, Henry Chin & Associates: BPA is probably one of the most studied chemicals in history. There have been hundreds of studies on the potential health effects of BPA conducted over the past 30 years. These studies and almost all officially sanctioned reviews of available studies conclude that humans are not at risk by eating foods that may contain traces of BPA in some packaging materials.
FACTS: it Is safer than families avoid BPA?
HC: Since the BPA does not pose a risk, there is no valid reason for families to avoid BPA scientific reason.
FACTS: What do you think has led to all the media coverage of BPA?
HC: I do not entirely blame the media for the coverage volume on BPA. The media have a responsibility to report new information about alleged risks or health hazards. Researchers have an incentive to publish interesting results, and often these results are “interpreted” creatively to create more media coverage.
FACTS: How does science on BPA coverage?
HC: Media coverage of BPA apparently been limited to stories focusing on individual experiments with unproven conclusions and uncorroborated. There is little coverage that includes experts examining the totality of the evidence.
It is true that the science of BPA is complex, but that science stripped of its complexity, is nothing more than rhetoric and should be seen that way.
3. Low-calorie sweeteners
FACTS: What do we know about low calorie sweeteners and their impact on our body?
Robyn Flipse, MS, RDN, Communication Services Nutrition : Low calorie sweeteners can make food and drinks to taste sweet, with few or no calories compared with sugar and other caloric sweeteners. Levels do not increase blood glucose or insulin requirements and are non-cariogenic, so do not contribute to tooth decay. Besides perceived sweet taste, they have little impact on the body, as mostly pass through unchanged.
FACTS: What do we know about the safety of low-calorie sweeteners?
John Foreyt, PhD, Director, Behavioral Medicine Research Center, Baylor College of Medicine : All sweeteners low approved calories have been studied and reviewed rigorously by government and scientific bodies worldwide, before being used in food and beverages . Low – calorie sweeteners approved by the FDA, meet the same safety standards as other foods are safe for consumption, even for pregnant women and children.
FACTS: Based on the research, what families need to avoid low-calorie sweeteners?
Julie Jones, PhD, CNS, CFS, LN, distinguished academic and professor emeritus of the department of family, consumer and nutrition sciences, University St. Catherine: No. Like everything in nutrition, balance is needed. It is important to use tools such as low – calorie sweeteners along with a balanced diet, otherwise some patients see the impact of poor diet and blame the low – calorie sweeteners.
FACTS: What is the craziest statement you’ve seen on a low-calorie sweetener or low-calorie sweeteners in general?
JJ: That the low – calorie sweeteners cause weight gain, when research actually shows that low – calorie sweeteners are useful for reducing calories for those struggling with weight.
RF: It always amazes me the number of people who believe that low calorie sweeteners can cause cancer, when neither the National Cancer Institute or the American Cancer Society appoint the low calorie sweeteners as one of the dietary factors which can increase the risk of developing cancer.
FACTS: How does science in the way that low-calorie sweeteners are covered by the media and online?
JJ: I would like the best fit science. Those who have the ‘microphone’ earn by using emotion. Many consumers do not understand that science can change, because methods change. I think we have to present studies and reviews as the “Non – Caloric Sweeteners and Obesity” John Fernstrom , showing how low calorie sweeteners are useful for people with diabetes and those struggling to reduce calories.
RF: The news agencies must compete for our attention and this needs to drive for sometimes irresponsible way the news is reported. Most people do not read the entire article under the heading or the current study and important details are lost. I spend more of my time correcting misinformation that people read in the news about low calorie sweeteners, what really happened educating them about nutrition and health. It’s a full time job!
