Sugar vs fat, BPA in cans, and PCOS awareness month are all in the news this month so here are some links to more information on each of these topics.
This shocking NPR article covers this new paper about the sugar vs fat debate: 50 years ago, sugar industry quietly paid scientists to point blame at fat
In the 1960s, the sugar industry funded research that downplayed the risks of sugar and highlighted the hazards of fat, according to a newly published article in JAMA Internal Medicine.
The article draws on internal documents to show that an industry group called the Sugar Research Foundation wanted to “refute” concerns about sugar’s possible role in heart disease. The SRF then sponsored research by Harvard scientists that did just that. The result was published in the New England Journal of Medicine in 1967, with no disclosure of the sugar industry funding.
It’s hard to believe that researchers would do this! The worst part is that this type of thing is still happening. You can read some of Marion Nestle’s commentary at the end of the above article.
At least now research sponsors do have to be disclosed so we are hopefully getting better at preventing this type of thing. We must always look at who funds a paper.
A CNN article, Canned foods linked to BPA risk in new study reports:
A study published in the journal Environmental Research on Wednesday not only reveals that consuming canned foods can expose our bodies to BPA, it pinpoints the worst offenders.
The study suggests that canned soups and pasta can expose consumers to higher concentrations of BPA than canned vegetables and fruit – and although those foods are tied to BPA concentrations, canned beverages, meat and fish are not.
BPA stands for bisphenol A, it’s a chemical that is found in plastics and it behaves in a very similar way to estrogen in the body. Because of this it’s called an endocrine disrupter and has an impact on depression, ADHD and anxiety.
An animal study published in 2015, Hypothalamic-pituitary-adrenal axis hyperactivity accounts for anxiety- and depression-like behaviors in rats perinatally exposed to bisphenol A reports
hyperactivity of the HPA [hypothalamic-pituitary-adrenal axis] is an important link between perinatal BPA exposure and persistent potentiation in anxiety and depression
It’s unfortunate they didn’t get a commentary from the Environmental Working Group which has a great short Guide to BPA.
September is PCOS awareness month and here is some wonderful information on yoga for anxiety and PCOS, from my friend and PCOS expert Amy Medling at PCOS Diva. I’m such a big fan of yoga for stress and anxiety but had no idea it could improve these PCOS symptoms:
Yoga can reduce anxiety symptoms, reduce mFG score for hirsutism, improve menstrual frequency, insulin values and more according to a 2012 study. For more about the benefits of yoga for women with PCOS check out this blog post: 5 Reasons Why Yoga is Beneficial for PCOS
In case you’re not familiar with PCOS, Amy shares this overview on her site
PCOS Polycystic Ovarian Syndrome (PCOS) is one of the most common endocrine disorders found in women, affecting approximately 10% of women worldwide, with less than 50% of them diagnosed. The syndrome is present throughout a woman’s life from puberty through post-menopause and affects women of all races and ethnic groups. Women with PCOS wrestle with an array of possible symptoms including obesity, irregular menstrual cycles, infertility, depression [and anxiety], acne, and hair loss. Far reaching health implications such as increased risk of cardiovascular disease and diabetes make these already stressful symptoms even more daunting.
What do you think? Are you shocked about the sugar study discovery? Do you already avoid BPA? Do you have PCOS or know someone who has PCOS?
