Flavour of the Week

TGIF


“It’s easier to change a man’s religion than to change his diet.” Margaret Mead

  • Apparently it’s easier to do taxes too! In a survey of 1,057 American adults, 52% report that doing their own income tax is easier than knowing what to eat. Ouch! The majority of people (76%) identified ever-changing nutritional guidance as a major barrier to changing their food habits, so clear messaging from professionals is as important as ever.
  • Part 1 in the Globe and Mail’s series on children’s fitness and education: physical inactivity in children is about more than just obesity rates, but also improved learning and behaviour too.
  • Want your partner to eat better? New research suggests food dictatorships don’t work – consult and negotiate on dietary changes for success.
  • More reasons to focus on food first. Calcium supplements linked to increased risk of heart attack – despite the media splash, this was correlational data only so don’t panic just yet! The EPIC study (keep in mind, EPIC was designed to study cancer risk) finds that intake between 920 – 1100 mg (read: adequate!) seems to offer the most protection from heart attack. More was not any better and confered no additional benefit. Key message? Think of Goldilocks when it comes to calcium – not too little, not too much, just right. When possible, obtaining what you need from your diet is best.
  • Variations in “obesity genes” FTO and BDNF, which control appetite regulation in the brain, linked to consuming more calories, greater meal and snack frequency, higher fat intake and more “other” foods (fats, oils, sweets).
  • Delivery method linked to obesity later in life?  UK study links Caesarean section delivery to higher rates of pediatric obesity compared with vaginal delivery. Not a matter of fetal programming necessarily (as we discussed earlier this week), but more likely due to gut microflora. Children born via C-section have more Firmicutes, less Bacteroides – this composition is correlated with higher obesity rates. See our previous post on Probiotics and Weight Loss? for more information on gut microbiota and obesity.
