Do Processed and Red Meat Cause Cancer?

Today, the World Health Organization's International Agency for Research on Cancer published a statement in The Lancet detailing its position on the carcinogenicity of processed and red meat (1).  The statement, resulting from a meeting of 22 scientists from 10 countries, concluded that processed meat is a group 1 carcinogen, meaning that it is "definitely carcinogenic to humans".  They also judged that red meat is a group 2A carcinogen, meaning that it probably causes cancer but the evidence isn't as strong.  They're mostly referring to the links between processed and red meat and digestive tract cancer, particularly cancers of the colon and rectum.

These statements were met with a media frenzy, and the expected furor from the meat industry.  The most surprising thing, for me, is that anyone would be surprised by the IARC's statement.

Why Do Girls and Boys Reach Puberty Younger Than They Used To?

Girls, and probably boys, are reaching puberty years younger than they did in our great-grandparents' generation.  Why?  There's no shortage of explanations, but the primary reason is probably quite simple.

8 Summer Steps for Healthy Living

In the warmer, longer, lazier days of summer, the living may not be easy, but your life probably feels less chaotic. Even adults tend to adopt a "school's out!" attitude in summer. That's why this is a perfect time to improve your health in a fashion so seasonally laid back you'll barely notice the effort.

To get you started, WebMD went to eight health experts in fields such as diet, fitness, stress, vision, and oral health. We asked them this: If you could only suggest one simple change this season to boost personal health, what would it be? Here are their top eight tips.

1. Give Your Diet a Berry Boost
If you do one thing this summer to improve your diet, have a cup of mixed fresh berries -- blackberries, blueberries, or strawberries -- every day. They'll help you load up on antioxidants, which may help prevent damage to tissues and reduce the risks of age-related illnesses. Blueberries and blackberries are especially antioxidant-rich.

A big bonus: Berries are also tops in fiber, which helps keep cholesterol low and may even help prevent some cancers.


2. Get Dirty -- and Stress Less
To improve your stress level, plant a small garden, cultivate a flower box, or if space is really limited, plant a few flower pots -- indoors or out.

Just putting your hands in soil is "grounding." And when life feels like you're moving so fast your feet are barely touching the stuff, being mentally grounded can help relieve physical and mental stress.

3. Floss Daily
You know you need to, now it's time to start: floss every single day. Do it at the beach (in a secluded spot), while reading on your patio, or when watching TV -- and the task will breeze by.

Flossing reduces oral bacteria, which improves overall body health, and if oral bacteria is low, your body has more resources to fight bacteria elsewhere. Floss daily and you're doing better than at least 85% of people.

4. Get Outside to Exercise
Pick one outdoor activity -- going on a hike, taking a nature walk, playing games such as tag with your kids, cycling, roller blading, or swimming -- to shed that cooped-up feeling of gym workouts.

And remember, the family that plays together not only gets fit together -- it's also a great way to create bonding time.

5. Be Good to Your Eyes

To protect your vision at work and at play, wear protective eyewear. When outdoors, wear sunglasses that block at least 99% of ultraviolet A and B rays. Sunglasses can help prevent cataracts, as well as wrinklesaround the eyes.

And when playing sports or doing tasks such as mowing the lawn, wear protective eyewear. Ask your eye doctor about the best type; some are sport-specific.

6. Vacation Time!

Improve your heart health: take advantage of summer's slower schedule by using your vacation time to unwind.

Vacations have multiple benefits: They can help lower your blood pressure, heart rate, and stress hormones such as cortisol, which contributes to a widening waist and an increased risk of heart disease.

7. Alcohol: Go Lite

Summer's a great time to skip drinks with hard alcohol and choose a light, chilled alcoholic beverage (unless you are pregnant or should not drink for health or other reasons).

A sangria (table wine diluted with juice), a cold beer, or a wine spritzer are all refreshing but light. In moderation -- defined as one to two drinks daily -- alcohol can protect against heart disease.

8. Sleep Well

Resist the urge to stay up later during long summer days. Instead pay attention to good sleep hygiene by keeping the same bedtime and wake-up schedule and not drinking alcohol within three hours ofbedtime.

It's also a good idea to avoid naps during the day unless you take them every day at the same time, for the same amount of time.

There they are: Eight super simple ways to boost your health this summer. Try one or try them all. They're so easy you won't even know they're -- shhhh -- good for you.

Will You Fill Out This Paleo Diet Survey?

This week, I received an e-mail from a graduate student at Humboldt State University named May Patiño.  She asked me to share her online research survey targeted to Paleo dieters.  Here are the goals of her research, in her words:

The main objective of my study is exploring how the Paleo diet is being implemented in practice.  I would like to assess the health outcomes of these practices, as well evaluate how closely they conform to, or deviate from ways this diet is being described in theoretical literature, and implemented in controlled diet trials. I also want to be able to use the data collected to help explain what is driving the popularity of the ancestral health movement. Ultimately, I would like this information to be used to better inform protocols for controlled diet trails.

The survey took me about 40 minutes to complete.  You're welcome to participate whether or not you're on the Paleo diet.  Please consider taking the survey, for the love of science!
