Recently, Best Food Facts received a question from Maddee asking, "What is the hormone level (estrogen) in beef compared to that of other animal protein products? With that, how does an animal that has been implanted with synthetic hormones (estrogen) excrete those hormones?”
To answer Maddee's question, Best Food Facts contacted Dr. Ann Macrina from Penn State.
When asked whether there is a correlation between the size of a farm and whether it sustainably produces food, food experts say it all comes down to management.
We received this inquiry from Best Food Facts reader Kathleen:
“Can anything be done on how we raise our chickens? The breasts are huge. Way too big. Then they put some solution in them which leaks out white goo while they’re cooking. On top, they have no taste. We can’t afford to buy Bell and Evens. There’s got to be a better way.”
With all the buzz over questions about whether antibiotics fed to animals raised for food cause human antibiotic resistance, it seems apparent that this issue is at the forefront of consumer concerns. As well, we received the questions, “Why are antibiotics fed to livestock inside CAFOs or feedlots? Is this dangerous to humans?” from http://www.fooddialogues.com/. To address the topic, and as a follow up to our previous posts on the subject, we asked experts Dr. Peter Davies and Dr. H. Scott Hurd to respond.
Many of you have seen it: the so-called "pink slime" video where food celebrity Jamie Oliver seeks to demonstrate to children how chicken nuggets are made.
We received the following inquiry from DeLyla regarding the white film on carrots:
"What is the scoop regarding baby carrots made from deformed carrots and then added bleach to them? Then, after a few days in your refrigerator the carrots get a white film on them? Is this chlorine and is it safe or does this cause health issues and or cancer?"
As the year winds down, we'd like to thank all of our readers for taking time to learn more about our food system. We appreciate your comments and questions! We'd also like to thank our food system experts for providing their thoughts and expertise throughout the year.
We noticed a discussion on a social media website asking, “Buying a chicken should be easy; labeling is confusing, what’s the healthiest?” Our food system expert Brenda Roche Wolford, M.S., R.D., University of California, Cooperative Extension, Los Angeles County, answers this question.
According to Dr. Stephen Taylor, no one knows the exact answer to why the prevalence of food allergies is increasing. He doubts any experts would hypothesize that chemicals used in food production play a role in the prevalence of food allergies. He explains other theories that seem much more plausible, but have not been proven, like clenliness, c-section births and avoidance of specific foods.
Best Food Facts asks readers what they think about the possibility of GM food labeling.
In the post, Hormones in Milk: Are They Causing Early Puberty in Girls, we wondered, what is causing early maturity in girls? Based on what Dr. Ann Macrina indicated, it could be any of several factors.
One of our readers, Dan, asked for clarification from Dr. Macrina: "Dr. Macrina indicated it could be any of several factors – better nourishment, higher body weight and some even suggest exposure to chemicals. Does Dr. Macrina mean chemicals like pesticides and herbicides?"
Food has gotten more and more expensive over the last several years and protein sources seem to be some of the fastest increasing items. Even one of the most affordable protein sources – eggs – has seen an increase in price. Along with the general increases across the board, there’s plenty of chatter regarding the price differences for eggs produced in different types of housing systems.
Following up on Dr. Oz's research finding arsenic in apple juice, Connie Diekman, RD, says she's not worried about the juice we have at home in our cupboards, but she would like to see more research and education about how juice should more appropriately fit into a healful eating plan. As we exit a holiday filled with positive stories and reasons to give thanks, we find one causing much concern - and reasonably so. As reported by several online sources, television shows, videos and bloggers, there are, once again, questions about arsenic in juice.
Food scientists are constantly exploring how to make foods taste better, digest easier, grow with fewer fertilizers, etc. We recently learned that a team of scientists at Iowa State University is working with the starches in sweet corn to try to create a response in the body that modify the starch to digest more slowly... which creates a more moderate insulin response, and release of glucose into the blood stream. This is important to the U.S.'s diabetic population of more than 21 million individuals, since moderating insulin and glucose through diet and medication is a constant need.
