The Healthy BBQ Did you have a great Fourth of
July? – barbecues, baked beans, potato salad, pulled pork, beer &
wine…luscious desserts...Monday morning regrets...and a few too many carcinogens with those ribs?
Besides the excess
calories, grilling fatty meats at high heat
creates harmful chemicals called heterocyclic amines (HCA) and polycyclic
aromatic hydrocarbons (PAH). These can
be hazardous to your health - regular consumers of well done grilled meats were
found to be 60% more likely to get pancreatic cancer.
Marinades, particularly with
spices & herbs can help reduce HCAs.
Rosemary has been found to reduce HCAs by up to 90% in some cases. Using a marinade with wine or beer six hours
before grilling can cut carcinogens by 40%. However, its been found than long
marinating times seem to cut the antioxidant activity in the sauces. So, a few hours is fine – overnight is not
necessary.
Use Lower Heat & try to keep
the temperature below 325°, but cook to an internal temperature of 160° for
burgers. Here's a chart of safe minimum
cooking temperatures from foodsafety.gov.
Precook In The Microwave – this reduces HCAs by 90%.
Just one or two minutes at medium can do the trick. And it’s recommended that you discard the
juice – HCAs concentrate there.
Add Veggies - Is there anything better than
grilled veggies? A nice mix of
vegetables will add healthy nutrients & antioxidants. Try some zucchini, fennel, peppers, onions or other thin sliced vegetables tossed with olive oil before grilling.
Here are some smart &healthy BBQ recipes from Health.com for BBQ ribs, chicken, salmon, meatloaf, BBQ sandwiches, pork, and more. Side dishes can be found here.
The MD
Anderson Center also has good information on BBQ safety and cancer prevention, which is found here.
In the News: For readers of the New York Times, you may have
come across an article by Aaron E. Carroll, MD entitled “To Lose Weight, Eating
Less Is Far More Important Than Exercise More”. Although Dr. Carroll cites
evidence that exercise improves outcomes for weight loss, the title of the
article, his reasoning, and conclusions are misleading. With the prestige of the NY Times behind his article, the danger is that John Q. Public will stop exercising.
A rebuttal by John M. Jakicic,
Ph.D., who is director of the Physical Activity & Weight Management
Research Center at the University of Pittsburgh, points out the role of physical activity in weight loss
interventions. In his article Dr. Carroll
emphasizes that neither weight loss intervention – diet or exercise – is more
important than the other. He reasons
that many people can lose weight, in the initial 3-6 months of almost any program, but that it is
challenging to maintain that loss without physical activity. Research has established that people lose
& maintain the most weight loss with a combination of dietary changes and
exercise.
Dr. Jakicic recommends eating appropriate portion sizes, following the current recommendations. For exercise, 30 to 60 minutes of activity per day. which can be broken into 10 minute intervals, is also commonly recommended. Lastly, folks should try to increase more activity into their daily lives to increase daily total energy expenditure.
My Opinion – we do tend to focus on more exercise (eg. The Biggest Loser, & Mrs. Obama’s Let’s Move program) as the key to weight
loss, while tending to lose focus on the importance of a healthy diet. Dr. Carroll’s contention is that even though
Americans are exercising more, we are more obese than ever, so that, therefore,
exercise isn’t working. In fact, his
article quotes studies that show exercise & diet are more effective than
diet or exercise alone. His other
references are meta-studies which have a built in bias in that the researchers
choose the studies they wish to include.
Meta-studies are not double blinded studies, but can give useful
information if done correctly. However,
until those studies are validated (meaning the results can be repeated), I’ll
go with the validated and verifiable exercise physiology & nutrition
studies quoted by Dr. Jakicic.
The Bottom Line: We could all eat more
healthily and move more throughout the day - 30-60 minutes a
day is really the minimum. The NY Times article &
headline could easily confuse those who don’t know the background of diet &
exercise research.
