Red Meat for Health: A Recent WHO/IARC Ruling

Red Meat for Health: A Recent WHO/IARC Ruling

You may have read articles or heard stories about the recent World Health Organization (WHO)’s International Agency for Research on Cancer (IARC) ruling on red meat. Unfortunately, the ruling stirred up quite a bit of fear and panic, so let’s go through what the IARC is, what the ruling means, and what actions should be taken for nutrition and health.

What’s the IARC and what does this have to do with red and processed meat?

IARC is part of the World Health Organization and three times a year, IARC forms working groups to evaluate how something (like certain occupational chemicals, foods, or even the sun) impacts the risk of cancer in people.

This quarter, they reviewed red and processed meat and released their report, classifying red meat as ‘Group 2A’ and processed meat as ‘Group 1’ (more on the classification definitions here).

What do these classifications mean?

Group 1 is defined as ‘carcinogenic to humans’ and Group 2A is defined as ‘probably carcinogenic to humans.’

IARC specifies that its classifications “do not measure the likelihood that cancer will occur (technically called “risk”) as a result of exposure to the agent.” The classifications also don’t capture consideration of quantity- for example, alcohol and sunlight are both Group 1.

It’s well established that overexposure to (or overconsumption of) both sunlight and alcohol comes with major health risks. That doesn’t mean there aren’t benefits to moderate levels of exposure (hello vitamin D!) to things like sunlight. Dr. Roger Clemens, a noted toxicologist points out the need to put IARC’s ruling in perspective:

“These rulings discuss hazard, but they’re reported as risk. For example, sunlight (hazard) is needed for vitamin D synthesis, yet excessive exposure increases one’s risk of skin cancer. Alcohol is a known liver toxin (hazard), yet when consumed in moderation (exposure) it reduces risk of developing adverse cardiovascular events.  There are many more examples like these. The Lancet article is clear that the evidence is weak or inconsistent. Importantly, IARC notes that its role is to identify hazard, not causality.”

How does this impact my diet?

Meat can certainly be part of a healthful, balanced diet, and the key is moderation. Just like sun exposure, too much may increase your health risks, but too little can leave you missing valuable nutrients. At this point, the Dietary Guidelines for Americans haven’t issued recommendations for quantity of meat in the diet. However, the Guidelines have encouraged lean proteins, along with whole grains and vegetables, for a healthful balanced diet. Keep your plate balanced, and be sure to watch your portion sizes.

What is a correct portion size?

The right portion size is a cooked 3-ounce serving of lean beef—about the size of a standard deck of playing cards. Of course, total calories, protein, and other nutrients will differ based on the type of meat. There are more than 30 cuts of lean meat in grocery stores; find your favorite, and enjoy with portion sizes in mind!

It’s important to remember that there’s a lot of variety within ‘processed meats’ too – it’s worth the time to check the nutrition info on your food to scope out the valuable stuff (Protein! Vitamins!) and make sure it fits in your calorie budget. The 2015 Dietary Guidelines Advisory Committee report included 3 USDA dietary patterns, which suggest the amount of food to meet recommended nutrient intakes at various calorie levels. The 2000 calorie diet includes recommendations for 12.5 ounces of meat (or equivalent) per week, approximately 4 servings, to meet nutrient needs.

What are some nutritional benefits of eating red meat?

Turns out, there are many benefits of eating red meat. Up first: protein.

Lean red meat is one of the best protein sources that we can eat, containing roughly 21-25g per 3 ounce serving. The protein found in red meat, as with all other animal products, is considered a complete protein source. This means that it provides our bodies with all the essential amino acids in the right amounts. Protein is not just associated with building bigger muscles- it also is responsible for the growth and repair of all our tissues, organs, and bones. Proteins facilitates the transportation of oxygen and nutrients through our bloodstream and across cell membranes. Proteins are essential for DNA replication, which is important for cellular turnover, and are key components of your immune system, which is critical for fighting disease! Protein also plays an important role in weight loss and weight maintenance as it contributes to the feeling of being full.

Red meat also contains a variety of highly bioavailable nutrients, including heme iron, zinc, and B-vitamins. Studies have shown that heme iron and zinc from animal sources are more easily transported across the membranes in our gut, aiding in the absorption of these minerals. This means that we get more bang for our buck in terms of iron and zinc from red meat. Iron is necessary for red blood cell health, oxygen transport, enzyme production, and mental development.

Zinc, on the other hand, plays an important role in boosting immune function, regulating hormones, and healing wounds. The high riboflavin content of red meat further facilitates the proper storage and facilitation of iron in our bodies. Additionally, red meat is a source of a variety of antioxidants, such as carnosine, anserine, and lipoic acid among others. These antioxidants protect against cellular damage and decrease the risk of excessive inflammation.

So what does this all mean and what should you do moving forward?

Bottom line, meat is an excellent source of protein and other important nutrients we are lacking in our diets. It packs a great nutritional punch. By controlling portion sizes and choosing lean cuts, red and processed meat can be part of a healthful diet.

The Ultimate Guide to Help You Sleep Through the Night Tonight

The Ultimate Guide to Help You Sleep Through the Night Tonight

It’s well past midnight and you’ve got to get up in less than six hours. You toss and turn all night. Before you know it, another hour passes by and you start panicking.

If I don’t get to sleep in the next 30 minutes, I’m going to be exhausted tomorrow!”

One thing is for sure, you’re not alone. Over 70M+ Americans have stated that they don’t get the proper sleep they need at night.[1] So what could possibly be causing this insomnia epidemic?

Throughout my entrepreneurial journey of building my language learning company, I have experimented and researched dozens of best sleep practices. Some have flopped but a few have dramatically improved the quality of my life and work.

In this article, I’ll look into the reason why you’re sleep deprived and how to sleep through the night tonight.

Why you can’t sleep through the night

The first step to improving anything is getting to the bottom of the root problem. Different studies have shown the reasons why most people cannot sleep well at night.[2] Here are the main ones that the average person faces:

Stress

If you’ve ever stayed up at night worrying about something, know that it’s a major sleep inhibitor. When you’re feeling stress, your mind and body becomes more activated, making it incredibly difficult to fall asleep. Even when you do manage to sleep, it won’t be deep enough to help you feel rested the next day.

Exposure to blue light before sleep time

We’re exposed to harmful blue light on a daily basis through the use of our digital screens. If you’ve never heard of blue light, it’s part of the visible light spectrum that suppresses melatonin, our sleep hormones. Other harmful effects include digital eye strains and macular cellular damage.

While daytime exposure to blue light is not very harmful, night time exposure tricks our brain into thinking it’s daytime. By keeping your brain alert and suppressing melatonin, your mind is unable to shut down and relax before bedtime.

Eating close to bedtime

Eating too late can actually be an issue for many people, especially those who are older than 40. The reason is, eating before laying down increases the chances of Gastroesophageal reflux disease (GERD), in which stomach acid backflows into the esophagus.

Another reason not to eat too late is sleep quality. Even if you manage to sleep right after eating, it’s likely that you’ll wake up tired. Instead of letting your body rest during sleep, it has to digest the food that was entered before bedtime.

Rule of thumb: eat 3-4 hours before bedtime.

Medical conditions

In some cases, it could be medical conditions that cause your sleep problems. If you can’t relate yourself to the above reasons or any of these common sleep problem causes, you should visit the doctor.

The vicious sleep cycle

The biggest danger to repeating the bad habits mentioned above is the negative cycle that it can take you through. A bad night’s sleep can affect not only your energy but your willpower and decision making skills.

Here’s an example of a bad sleep pattern:

You get a bad night’s sleep
–> You feel tired and stressful throughout the day.
–> You compensate it with unhealthy habits (for example junk food, skipping exercises, watching Netflix etc.)
–> You can’t sleep well (again) the next night.

    You can imagine what could happen if this cycle repeats over a longer period of time.

    How to sleep better (throughout the night)

    To help you break the vicious cycle and stop waking up in the middle of the night, I’ll explain to you a list of actionable steps to solve your trouble staying asleep.

    1. Take control over the last 90 minutes of your night

    What you do (or don’t do) before bedtime have significant impact on the quality of your sleep. Many times, it can be the difference between staying up until 4am and sleeping like a baby.

    Here are a few suggestions:

    • Go from light to dark – Darkness stimulates production of the sleep hormone melatonin. Turn off unused light around the house, and think about investing into warm light that you can use in the bedroom before bedtime.
    • Avoid screens (or wear blue light blocking glasses) – Keep the bedroom a technology-free zone as the light from electronic devices can disturb your sleep. If you need to work, wear blue light blocking glasses (also known as computer glasses) throughout or before you sleep to prevent sleep disruption.
    • Find an activity that helps you to wind down  This could be anything that calms you down, and reduces thinking (especially unnecessary stress). Fir example, listening to soothing/good feel music, taking a hot bath, reading or meditating.
    • Keep any electronics you have on the other side of the room or outside the room – One of the most harmful things that can disrupt your sleep is the notifications you get from your smartphones. The simplest way to avoid this is to keep it away from you.
    • Create a bedtime routine – A night routine is a couple of things you do prior to going to bed. By doing these things every night, you’ll have a more restful and high-quality sleep.

    2. Eat the right nutrients (and avoid the wrong ones)

    What you eat (not just when we eat) plays a critical role in your sleep quality. If you’re ever in doubt of what to eat to improve your sleep, take the following into consideration:

    • Kiwi – This green fruit may be the ultimate pre-bed snack. When volunteers ate two kiwis an hour before hitting the hay, they slept almost a full extra hour. Kiwis are full of vitamins C and E, serotonin and folate—all of which may help you snooze.
    • Soy foods – Foods made with soy such as tofu, miso and edamame, are rich in isoflavones. These compounds increase the production of serotonin, a brain chemical that influences the body’s sleep-wake cycle.
    • Fiber-rich foods – Eating more fiber could be key for better sleep. Eating fiber was associated with more restorative slow-wave sleep—the more you eat, the better you sleep—per a study published in the Journal of Clinical Sleep Medicine. Fiber prevents blood sugar surges that may lower melatonin. Get a fiber boost from beans, artichokes, bran cereal and quinoa.
    • Salmon – Most fish, especially salmon, halibut and tuna boost vitamin B6, which is needed to make melatonin— a sleep-inducing hormone triggered by darkness.

    3. Adjust your sleep temperature

    Once you’ve gone through the first 2 recommendations, the last step to experiment with is temperature. According to Sleep.org, the ideal temperature for sleep is 60-67 Farenheit. This may be cooler than what most people are used to, but keep in mind that our body temperature changes once we fall asleep.

    Rule of thumb: sleeping in cooler temperature is better for sleep quality than warmer temperature.

    Sleep better form now on

    Congrats on making it to the end of this guide on sleep. If you’re serious about taking the necessary steps in improving your sleep, remember to take it one step at a time.

    I recommend trying just one of the steps mentioned such as taking a hot bath, blocking out blue light at night, or sleeping in cooler temperature. From there, see how it impacts your sleep quality and you can keep doing what works, and throw away what doesn’t.

    As long as you follow these steps cautiously and diligently, I know you’ll see improved results in your sleep!
