The 8 Years Younger Study
In this study, researchers from the University of California San Diego (UCSD) studied 1,481 people. Their question was simple. What is the least amount of physical activity you need to reverse biological aging.
To answer their question, researchers measured the length of telomeres in the white blood cells of these 1,481 people. Telomeres, which are shown in the photo accompanying this article, can be found at the ends of your DNA. Telomeres are like the plastic tips at the end of shoelaces which prevent the shoelaces from unraveling and falling apart.
As part of the aging process, these telomeres gradually shorten over the years. When they get too short, your DNA starts to unravel and fall apart. When this happens, heart disease, cancer, or death are near at hand. The key is to always keep your telomeres as long as possible.
In order to link physical activity to telomere length, UCSD researchers strapped pedometers to these 1,481 people for one week. They then compared the pedometer data to their telomere length.

The Harvard Meat Study
Meat studies are difficult to do. These studies often are not very accurate either.
This is because health conscientious people tend to eat less meat. If they do eat meat, it is generally fish or poultry.
In contrast, people who don’t care much about their health are more likely to eat a meat heavy diet. They also like to load up on red and processed meats. The question is always, was it the meat or their lifestyle that accounted for the increased cancer, heart, and premature death risk.
This study was different because the lifestyle variable was taken out of the equation. Specifically, they analyzed the effect of various meats on people with with both a healthy and unhealthy lifestyle.
In this latest meat study, Harvard University researchers followed 131,342 people for up to 26 years in hopes of answering the question, does meat cause cancer, heart disease, or an early death. Here are the three key...

Liz was the classic yo-yo dieter. Every year she’d resolve to lose weight on January 1. And every year, by about April or May, she had gained it all back plus a few more pounds.
Last spring, as Liz’s weight crept ever upward, she started developing shortness of breath and fatigue. Even the little things, like walking up stairs, made it hard to breathe.
When she went to see her doctor, her doctor noted that her pulse was fast and irregular. An EKG was done which showed an abnormal heart rhythm called atrial fibrillation.

Growing up, I struggled with wintertime depression. Typically, this hit me within a few hours after opening presents on Christmas day.
While wintertime depression never stopped me from other activities, I always felt somewhat melancholic from Christmas day until March. Looking back, I rarely went outside during this period of time.

How to Eliminate Stress Study
In this study, Dr. Michael J. Poulin and colleagues from the University of California, Irvine, studied 846 people living in the Detroit, Michigan area. Knowing that stress is associated with heart attacks and premature death, Dr. Poulin and his team wanted to see whether helping others could reverse the life threatening risks of stress.
To answer this question, each person in the study underwent an interview in the late 1980s to determine how stressful their lives were, their health problems, and how much time they spent helping others. Dr. Poulin and colleagues then checked in with study participants every five years.
As they followed these people over time, they found that those who lived stressful lives were 30% more likely to die a premature death. Quite remarkably, those who reported helping others were not only spared a premature death but actually lived longer.

Knowing whether it is a cold or allergies can help you get the treatment you need and avoid all the stuff you don’t need. In this article, I share 5 ways to determine if it is a cold or allergies. I’ll also teach you how to avoid both conditions in the first place.
What causes colds?
Colds are caused by viruses. These viruses are easily transferred by breathing them in through your nose or by touching something.
As it is impossible to tell who around you might be coming down with a cold, your main defense is to not let your body get run down and to wash your hands frequently. Hand washing is particular important given the fact that viruses can live on a door handle for up to 24 hours.

New Sugar Guidelines for Kids
According to the new sugar guidelines for children, children over age two should consume less than six teaspoons (25 g or 100 calories) of added sugar each day. For children under age two, there is no safe amount of added sugar they can eat.
I should emphasize that these guidelines refer only to added sugar. Thus, the naturally occurring sugars in unprocessed fruits, such as an orange, apple, or banana don’t count toward the limit.

How My iPhone Helps Me Sleep
As most readers know, I have struggled with sleep for most of my life. A few years ago, I finally figured out that if I could just do five things religiously, I could finally fix my sleep problems.
What has worked for me, may or may not help you. If these five tips don’t help you, keep reading as there are many more tips later in this article.
1. Strict bedtime of 10 pm
My iPhone helps me keep a strict bedtime of 10 pm. The blue light coming from my iPhone automatically turns off at 9 pm. I also get a reminder at 9:45 pm to get ready for bed.

Processed grains, on the other hand, are really just sugar. It’s also pretty clear that processed grains are responsible for much of the obesity crisis, as well as the epidemic of atrial fibrillation, heart failure and diabetes that I see in my cardiology practice every day.
Everyone Loves Processed Grains
After a five hour winding five hour bus ride through the thick mountain foliage of southwest China, not far from the Vietnam border, we met Fang. When our family arrived it was after midnight and we were in the middle of a torrential downpour.
His was the last taxi and he agreed to take us the last hour of the journey to China’s Longevity Village. As part of our conversation, he shared with me that he grew up in China’s Longevity Village and then moved to Bama city as an adult to find work.

Chocolate, High Blood Pressure, and Kuna Indians
In 1944, an obscure army surgeon, Dr. B. H. Kean, was stationed in the Panama Canal Zone by the U.S. army. While there, he noticed that the Kuna Indians, who lived on the San Blas Islands off the coast of Panama, didn’t get high blood pressure. Even as they aged, their blood pressure still stayed in the very healthy 110/70 mmHg range.
Dr. Kean published his observations in 1944, but no one paid attention. In fact, for the next 50 years, his findings lay buried in a medical journal. It wasn’t until the 1990s that Harvard physician and hypertension researcher, Dr. Norman Hollenberg , discovered Dr. Kean’s 1944 article.
The Medical Mystery of the San Blas Islands
Dr. Hollenberg was an expert in the genetic causes of high blood pressure.

This recommendation comes despite the fact that “statins,” may increase your risk of diabetes by 46%, may cause memory loss, may increase coronary artery calcification, and can damage your muscles.
Cholesterol is just one of many risk factors for heart disease. Fortunately, there are better ways to lower cholesterol. In this article, I share the three best ways to lower cholesterol naturally.
My Bad Cholesterol Gene
I was not born with the low cholesterol gene. Even worse, I inherited one copy of the ApoE4 gene. Sadly, one in four Americans also have at least one copy of this ApoE4 gene as well.

In this article, I’ll cut through the hype and focus on what the science tells us. Read on to discover the top three benefits and risks of raw foods based on the latest medical studies.
My Raw Food Journey
At one point in my life, the closest I ever came to raw foods was an occasional bag of carrots or the standard dinner salad. In fact, raw versus cooked was something that was never even on my radar screen.
Since my health turn around a few years ago, I now eat raw foods every day. While you won’t find me drinking unpasteurized milk or eating raw meat, you will find me eating a heaping salad or munching on raw vegetables.
Personally, I don’t take sides in the raw versus cooked debate. As there are benefits to both, I enjoy the best of both worlds.

It was literally a race against time to prevent irreversible water damage. I quickly fished my iPhone out of the toilet with my hand, powered it off, dried every aspect of the phone, and waited for the inner components to dry.
Life without Multitasking
For an entire weekend I was without my iPhone. I had to wait for everything to dry. If I was even tempted to turn it on, the inner electronics would likely be forever destroyed.
Once I got beyond the initial frustration of dropping my iPhone into the toilet, I started tuning in more to my family. No one could call or text me. Nor was I be tempted to check email or something on the Internet while I was with my children. For an entire weekend, I didn’t multitask.

Your grandmother was full of good advice. But if she told you that “breakfast is the most important meal of the day,” you only got part of the story.
An early meal can be a vitally important part of the day — for some people, and only if it’s a truly healthy breakfast.
What is a healthy breakfast?
What’s a truly healthy breakfast look like? Well, it looks something like what a lot of people have for dinner: A big salad with nuts and seeds on top served with some wild salmon and fruit.
As for the more standard American breakfast foods — processed cereal, pancakes or waffles doused with syrup, processed meats and fruit juice — that really couldn’t be a worse way to start the day. You might as well not eat breakfast at all.

1. Set an Example
Your children watch what you eat. Indeed, studies show that, to a large extent, how you eat is how they will eat for the rest of their lives. Any bad eating habits you have may be magnified with your children.
Basically, the message of this and countless other studies is that you have to “walk the talk.” If you don’t eat vegetables, then you can’t expect your children to eat vegetables either. As studies show that vegetables eaten during childhood prevent future heart disease and cancer, it is a parent’s responsibility to model healthy eating.

In this article, I share the five proven secrets to younger looking skin.
1. Daily Skin Care
Studies show that proper skin care can make you look two years younger. Proper skin care doesn’t mean scrubbing your face until it is squeaky clean. It also doesn’t mean lots of expensive skin care products.
According to my dermatology colleagues, for most people, a gentle face clean before bed may be enough. You don’t need to scrub hard or use harsh soaps. This goal of this gentle face cleaning before bed is to remove dirt, bacteria, oil, pollutants, and makeup.
A daily moisturizer can also help your skin to look young. Moisturizers protect your skin from weather and from drying up.

In this article, I will answer how much water should you drink and debunk the top 10 hydration myths based on the latest medical science.
The Top 10 Hydration Myths
1. Drink 8 Glasses of Water
The biggest hydration myth is that you must drink eight glasses of water every day. Even my children have been taught this in school.
Guess what, no medical study has ever shown that you need eight glasses of water. The best medical studies I could find recommended five and six glasses daily.

The Aedes Mosquito and the Zika Virus
The Zika virus is carried by the Aedes mosquito. The scary thing is that the Aedes mosquito visits a large portion of the United States. Basically, if you live along the coasts, or in the southern part of the U.S., you are at risk. Here is a map, to see if your home is at risk from this mosquito.

Unfortunately, if you want to be outside much this summer, sunscreen is a necessary evil. Studies show that being physically active outside may offer far more benefits to your physical and mental health than exercising in a gym.
As a parent of four children, I know just how challenging sunscreen issues can be. Read on to find out the the three critical things to know about sunscreen so that you can be sun smart.
1. Sunscreen May Not Prevent Skin Cancer.
Growing up, I thought that sunscreen was protecting me from skin cancer. Unfortunately, I later learned that there are little data from medical studies backing this up.

Michael’s Experience
Michael was my typical hard charging CEO patient. He routinely put in 60-hour workweeks and his health suffered. For years, I encouraged him to start exercising. Unfortunately, I always got the same response.
“Doc, I just don’t have time to exercise.”
Our breakthrough finally came when I talked with him about compressing a workout into just a few minutes several times a week.
“Will exercising such a short time even do any good?” he asked.
“All the benefits of a long exercise session in just a fraction of the time,” I said.
“Count me in,” he said.

As magnesium is found in nuts, seeds, and greens, is it any wonder that up to 89% of Americans are magnesium deficient? The Standard American Diet is very low in magnesium. Magnesium is critical for everything from DNA repair to keeping your heart beating normally.
Arrhythmias, or abnormal heart rhythms, are very common. The main symptom of an arrhythmia is heart palpitations.
Studies show that one in four adults will experience the most common arrhythmia, atrial fibrillation. Even palpitations from skipped beats (PVCs and PACs) are very common and trouble many people.
Besides living as healthy as possible, are there any proven natural home remedies?
Let me introduce you to magnesium. As a cardiologist, I have seen countless patients benefit from either increasing the magnesium in their diets or from magnesium supplementation. Unless you suffer from kidney disease, magnesium supplements are generally safe.
In a review of 17 medical studies involving 2,069 patients, magnesium supplementation was shown to decrease nearly all arrhythmias following surgery. In particular, the risk of atrial fibrillation was decreased by 29% and ventricular arrhythmias by 48%.

1. Yogurt
Yogurt is part of any healthy breakfast, right? While yogurt can be healthy, most yogurt options at your local grocery store is anything but healthy.
For example, one small Yoplait original strawberry yogurt has 26 grams of sugar. That is more than six teaspoons of sugar.
Even worse is that sugar is listed as number two on the ingredient. To put this in perspective, a Twinkie only has 18 grams of sugar.
If obesity and diabetes weren’t bad enough, studies show that added sugar is a major cause of heart disease. Fortunately, yogurt can be healthy if there is no added sugar and live bacterial cultures (probiotics) are present.
Look for “plain” yogurt and read the ingredient list carefully. You don’t want any added sugar. Likewise, you want live cultures.

In this article, I’ll cover the latest medical studies on the Paleo Diet. I’ll also discuss the benefits and possible risks of the Paleo Diet.
What is the Paleo Diet?
The Paleo Diet is really simple. If something wasn’t around during caveman times, you shouldn’t eat it.
One unique aspect to the Paleo Diet, compared to other diets, is that the Paleo Diet is considered a lifestyle by most followers. Indeed, there is an entire culture now built around this “Paleo Lifestyle.” With a strong paleo culture in place, it makes it much easier to stick with this way of eating long-term.

Inflammation is a silent killer that not only causes chronic pain and fatigue now, but also puts you at risk for Alzheimer’s Disease, cancer, or arthritis. This article will teach you everything you need to know about how to stop inflammation now.
How bad is breathing bad air?
The air this past week in Salt Lake City has been especially dangerous. Red air days have been common. For most of this past week, our beloved mountains were hidden by dense smog. Here is a photo from our local newspaper to show just how bad the air has been.
When our air pollution is bad, my hospital fills up with patients. We see many patients with respiratory problems and heart attacks on these red air days. It gets so bad that our local schools won’t even let our kids go outside for recess.

American Heart Association’s Salt Recommendations
The American Heart Association continues to preach that Americans should reduce their 3,400 mg average of sodium each day to just 1,500 mg. To put this in perspective, 1,500 mg of sodium is a little more than a half teaspoon of salt. Is it any wonder that only 1% of Americans can actually follow such strict salt restrictions?
