The Unexpected Benefits of Exercise

As if being able to fit into your jeans from college isn’t enough of a reason, sufficient exercise can bring a wide variety of serious health benefits. Besides the obvious weight loss, improved muscle and cardiovascular function, as well as increased longevity, exercise brings with it a host of unexpected benefits. In general, those who exercise regularly are actually “biologically younger” than those who do not exercise regularly, therefore, they are at lower risk for age-related disease and physical decline.

A new study suggests a strong link between exercise and eye health. The study suggests that regular exercise can lower the risk of macular degeneration resulting from age by up to 70%. Physical activity reduces inflammation in the blood vessel walls the results from the disease.

Exercise can significantly increase how quickly you fall asleep, and improve the overall quality of your sleep. As your metabolism becomes more efficient, your body is able to make the downgrade from awake to asleep faster. In other words, your body does not to remain active as long to maintain your metabolic balance. Not only that, but exercise allows you to wake up faster and feel more rested, even if you got a little less sleep than normal.

Exercise is also great for your skin. Healthy skin requires sufficient water and oxygen to look and feel it’s best. The heavy breathing and increased heart rate associated with exercise increase your circulation, which carries oxygen throughout the body, including the skin. Increased muscle mass and reduces fatty deposits can also result in tighter, smoother feeling skin, as the skin is literally being pulled more tightly over the muscle.

Sports involving small, fast moving objects like tennis can improve your general ability to focus. In addition to improved concentration, your eyes will actually physically focus faster. A strong link has also been shown between exercise and memory and other cognitive functions. Exercise also significantly improves balance, which can have positive effects in many different areas.

Don’t sweat! People who exercise often tend to sweat less when not working out than those who don’t exercise regularly. The body uses the exercise time to sweat out toxins and excess water. In addition, regular exercisers have lower resting heart rate, which keeps their bodies from heating up and sweating during regular tasks, like climbing stairs.

If taking care of yourself isn’t enough, then do it for your kids. Studies show that parent who have healthy exercise routines and diet are more likely to raise kids with the same habits. Not to mention if you live significantly longer, you will have more time with your loved ones.

So how much do you need to exercise? Adults should do a minimum of 2 hours and 30 minutes a week of moderate-intensity aerobic physical activity. Health benefits increase significantly at 5 hours per week. Adults should also do exercise to strengthen their muscles using all major muscle groups at least 2 days per week.  While it’s less than ideal, recent studies have found significant health benefits from exercising only 15 minutes a day.

Exercise is one of the most important components of an anti-aging lifestyle, along with nutrition, sleep, and stress reduction. In addition to looking and feeling great, exercise provides an incredible amount of health benefits. Rejuvalife Vitality Institute offers comprehensive fitness and nutrition programs, as well as medically supervised weight loss, to support your overall health, beauty, and well-being.

Don’t Stress Over Stress

Stress, in and of itself, isn’t necessarily a bad thing. For our earliest ancestors, stress could have meant the difference between life and death in the face of a hungry saber-toothed tiger. Stress activates our body’s sympathetic nervous system, inducing the so called “fight-or-flight” response, causing our adrenal glands to release a flood of hormones, including adrenaline and cortisol. Adrenaline serves to temporarily increase heart rate, elevate blood pressure, and boost energy supplies. Cortisol increases blood glucose and delivers more of it to the brain. In small doses, this stress can be just the extra kick we need to perform well on a test, meet a difficult deadline, or perform in front of an audience. This is generally followed by a period of rest, when the body and adrenals have a chance to recover and return to equilibrium. When we stress our muscles, say through weight lifting, it forces our muscles to grow over time to be able handle greater degrees of stress in the future. A similar mechanism serves as the foundation for the way we learn new skills and information, by constantly pushing ourselves beyond our current comfortable capacity, we train ourselves to handle increasingly greater demands. Stress is critical for growth.

It’s only when stress becomes chronic and uncontrolled that it can become an issue. Stress can be especially toxic when a difficult event happens and a person feels they do not have the financial or internal resources to handle it. When chronic stress becomes a part of life, serious physical and mental health consequences can develop. This is due in part to a somewhat paradoxical problem. Prolonged exposure to adrenaline and cortisol in the bloodstream can contribute to prolonged elevated heart rate, blood pressure, and blood sugar, which can cause a number of issues. At the same time, the adrenal glands can weaken due to overworking, resulting in diminished ability to produce enough adrenaline and cortisol to meet the stress.

According to a statistic from the American Academy of Family Physicians, stress-related symptoms account for two-thirds of all office visits. Several studies link high levels of self-reported stress to significantly increased mortality rates. This is due a number of different factors. For one, there are higher risk and complication rates of diseases. High levels of stress are linked to increased risk and symptom complications for heart disease, heart attack, cancer, stroke, obesity, type II diabetes, anxiety, depression, asthma, psoriasis, eczema, sleep issues, and memory impairment, to name a few. High stress also has a strong link to lower immune function, which can contribute to increased mortality due to any number of illnesses. Certain predisposed genetic factors that make some people more susceptible to stress than others may also contribute to mortality rates.

Several key lifestyle changes and practices can help reduce stress. A growing body of research is supporting the health benefits and stress fighting properties of meditation. Meditation has been shown to lower blood pressure and improve immune function. A recent study showed that regular meditation improved physical and emotional responses to stress. Participants who meditated regularly experienced less immune system activation and emotional distress in response to stressful situations.

Regular exercise is critical for coping with stress, as well as healthy diet and nutrition. Reducing caffeine and sugar intake can reduce spikes and crashes in mood and energy, which can help with stressful situations, in addition to promoting relaxation and better sleep. While alcohol, cigarettes, and drugs may provide a feeling of temporary relief, they interfere with addressing the underlying issues that contribute to stress in the first place, and may cause other health issues that contribute to stress. Sufficient sleep, 7-8 hours per night, is necessary to have sufficient energy to deal with stressful situations. Several mental, emotional, and behavioral changes in the way you cope with stress can help to alleviate it, such as avoiding stressful people, learning to say “no”, avoiding stressful conversation topics, reframing issues as opportunities for growth, organizing time management, and focusing on the positive. Try to shift your focus to changing stressful environmental factors that are in your control, and learning to cope with or avoid factors that can’t be controlled.

If stress is taking a significant toll on your wellbeing, and efforts to address it have not been effective, Rejuvalife offers a comprehensive stress management program, designed to diagnose and correct potential hormonal imbalances of DHEA and cortisol, and to manage aspects of diet, nutrition, fitness and lifestyle that may be contributing to stress. This allows stress to be taken off the adrenal glands, so they have a chance to recover and restore normal functioning. As cortisol contributes to the retention of abdominal fat, stress management may also play an integral role in a weight loss program. Rejuvalife operates on the principle that a person’s overall “looks” and external beauty are in large part a reflection of internal health and well being. If a person has poor internal health, of which stress can be a major contributing factor, this will show on their face, and their external beauty will be diminished. Stress management is therefore an integral part of a person’s anti-aging lifestyle and aesthetic enhancement regime.

Breast Cancer Prevention through Diet

In honor of October being National Breast Cancer Awareness Month, I want to encourage women to take an active role in living a prevention-oriented lifestyle through diet to reduce their cancer risk.

In 2007, the most recent statistics available, over 200,000 women in the United States were diagnosed with breast cancer, and over 40,000 died from breast cancer. Over recent years, more and more attention has been given towards lifestyle and dietary factors contributing to breast cancer.  Of course, no food or supplement is sufficient to completely prevent or treat breast cancer, and women should receive regular mammograms and consult with their physician, and take other lifestyle measures to improve breast health.

However, certain foods and supplements have been linked to reduced risk of breast cancer. Here are some guidelines for a breast cancer prevention oriented diet and lifestyle.

Don’t Eat Meat! - Red meat consumption is highly correlated with breast cancer. Try to limit or eliminate red meat from your diet, and consider eating vegetarian meals at least a few times per week for a boost of essential vitamins, nutrients and antioxidants.

Green is Gold – Broccoli and other cruciferous vegetables such as kale, collared-greens, and brussel sprouts reduce the production of a certain kind of estrogen specifically linked to breast cancer development. These foods are also especially high in fiber, which is essential for waste elimination and removing toxins from the body. Eating a high-fiber diet of at least 30 grams or more can significantly reduce carcinogenic toxins in the body and lower breast cancer risk.

Tea Time – Green and white teas are both especially high in antioxidants, which have a protective effect against cancer. Some studies have shown that green tea can interfere with cancer cell receptors. Coffee has also recently been shown to reduce the risk of breast cancer. Read More

 You say tomato… – The lycopene in tomatoes can reduce cancer risk by attacking free radicals, which are associated with cancer development.

 Go Nuts! – The Omega-3 fatty acids, antioxidants and phytosterols in walnuts have all been shown to have cancer-fighting properties.

Bittersweet News – Contrary to the popular belief that “cancer loves sugar,” sugar in your diet does not cause cancer to develop. Starving your cells of sugar won’t kill or prevent cancer, but can deprive your healthy cells of energy. However, obesity, increased insulin levels and diabetes related to a high-sugar diet are all strong risk factors for cancer. A healthy diet and sufficient exercise will contribute to a healthy body weight and normal insulin levels, and thereby lower your cancer risk.

Rejuvalife is here to support you in living a disease-prevention and anti-aging lifestyle, to create the radiant health and vitality you have always wanted!

Your coffee habit might be saving your life

“Can I please get a venti decaf, sugar-free hazelnut, non-fat, no foam, no whip, extra hot caramel macchiato with five pumps of sugar-free hazelnut syrup?” There’s no denying it. Coffee has become part of the American Culture and the American Diet.

Whether you’re a fan of our coffee culture or not, coffee is here to stay, supported by the fact that the average American drank 26 gallons of coffee in 2009. While this may sound like a lot, recent research has shown astonishing disease fighting and health improving properties of daily coffee consumption, especially in higher doses. People in the U.S. get the majority of their antioxidant intake from coffee. A typical serving of coffee contains more antioxidants than an average serving of blueberries. The properties of the special antioxidants and polyphenols found in coffee, along with the effects of the caffeine itself, may play a major part in prevention and ultimately treatment of a number of degenerative diseases.

One of the most recent findings to gain attention is coffee’s incredible association with lower skin cancer risk. A study of nearly 94,000 women found that daily coffee drinkers had an almost 11 percent lower risk of non-melanoma skin cancer, and that women who drank six or more cups daily had a 30 percent reduction in risk. In addition to actually being able to absorb UV rays, caffeine inhibits a chemical pathway responsible for repairing DNA damage in cells caused by UV radiation. While this repair process may sound like a good thing, the problem is that sometimes these cells don’t repair properly and can go on to become cancer cells. By inhibiting this process and letting these cells die, the  risk of them becoming cancerous is eliminated. Caffeine inhibits a similar process in breast cancer development, by promoting cell death of damaged, potentially malignant cells in the breast.

In addition to several other types of cancer, research has linked high, daily coffee consumption to reduced risk of Heart Attack, Heart Disease, Stroke, Dementia including Alzheimer’s Disease, Parkinson’s, Type 2 Diabetes, Liver Cirrhosis, and Asthma. Some studies have found that coffee actually improves social skills, and reduces symptoms of depression and rate of suicide.

Ok, so coffee fights cancer and heart disease, but is it really worth the bad breath? Contrary to the implications of the common phrase “coffee breath,” a study from the International Society for Breath Odor Research in Germany (yes, this is a real thing) showed that certain compounds in coffee may ultimately reduce bad breath by eliminating bacteria responsible for halitosis.

The verdict is in. Coffee has tremendous health benefits when included in your daily nutrition, as part of your anti-aging lifestyle. But not all coffee drinks are created equally. A 6 oz. cup of black coffee has about 7 calories. Add a bit of half  & half or creamer and you’re looking at about 50 calories. Every teaspoon of sugar you add from there is about 23 calories more. Do your body a favor and stay away from any of those fancy, sugar filled coffee concoctions. A 16 oz. Starbucks Mocha Frappuccino has 370 calories, 15 grams of fat, and 54 grams of sugar. A 16 oz. McDonalds Frappe, which makes the Starbucks Frappuccino look like a diet drink in comparison, contains a whopping 560 calories, 24 grams of fat, and 70 grams of sugar. That’s the same amount of sugar as 17 and a half of the sugar packets you might use to sweeten your regular coffee! Sugary, artificial coffee drinks have so much sugar that the harmful effects of consuming the sugar on a regular basis far outweigh the health benefits of whatever trace amount of actual coffee they may contain. Caffeine also increases metabolism and energy available for exercise which aids in weight loss, as long as you minimize added milk and sugar, and steer clear of the muffins, bagels, and donuts that often go with it.

Go Fish! – The Amazing Anti-Aging Benefits of Omega-3

Patients ask all the time which supplement is most important for an anti-aging lifestyle and disease prevention. Of course, every person’s body is different, and each person should consult with a physician regarding their nutrition and supplement choices, but Omega-3 essential fatty acids in particular stand out for incredible anti-aging and disease fighting properties.

Essential fatty acids are vital for normal metabolism, but cannot be synthesized by the human body. Because of this, people need to have a diet rich in Omega-3 fatty acids and/or take supplements to maintain healthy levels in the body. Omega-3 fatty acids are found in fish such as salmon, herring, mackerel, sturgeon, and anchovies, and are also found in seaweed, flax seeds, soybeans and tofu, walnuts, pumpkin seeds, and canola oil. Certain other foods like eggs and yogurt are also now being fortified with Omega-3 fatty acids.

A large body of research supports the incredible benefits of Omega-3 fatty acids for promoting heart health. A diet rich in Omega-3s has been shown to reduce the risk of atherosclerosis, irregular heartbeat, heart attack, sudden cardiac death, and heart failure. Omega-3s have a positive effect on regulating the heart’s electrical activity, muscle tone, and plaque stabilization, and also act as a blood anticoagulant. Omega-3s reduce blood pressure, lower “bad” cholesterol levels, increase metabolism, and aid weight loss, all associated with heart health and disease prevention. Omega-3 fatty acids have been linked to an astonishing number of other health benefits.

Other potential health benefits of Omega-3 fatty acids include:

• Reduces risk of stroke and certain cancers
• Reduces cellular inflammation
• Lubricates  the skin, arteries, veins and intestines
• Slows development of Alzheimer’s and other cognitive problems
• Reduces joint pain and arthritis symptoms
• Increases energy levels and concentration
• Improves sleep quality

The American Heart Association recommends including two meals of fish every week for optimal heart health, however, the American diet is typically lacking in sources of Omega-3s, so it is highly recommended that people take a daily supplement for optimal health and disease prevention. Rejuvalife offers a premium concentrated Fish Oil supplement, the purest and most effective source of Omega-3 fatty acids. We also offer a complete line of the highest quality Vitamins and Supplements, selected personally by Dr. Berger for the highest efficacy and purest ingredients, to support your anti-aging lifestyle and overall health. Any supplement you purchase can also be added to your Loyalty Punches for our Filler Frenzy Program, and contribute toward receiving your $300 gift card or free syringe of Juvederm Ultra, Restylane or Radiesse.  See offer for complete details.

Internet Addiction and the Wired Brain

Before I begin, I’d like to acknowledge that I do recognize the irony of writing a blog about the harmful effects of the internet.

The internet and modern technology certainly seem to make life easier and more efficient, but the consequences of living in a wired world may be severe. A growing body of research is connecting excessive internet and technology use with major negative changes to our cognitive function, mood, emotion, overall health and the physiology of the brain itself.

Our brains are hard-wired to respond to the instant gratification, fast pace, and unpredictability of the internet and new technologies.  We are designed to be stimulated and direct our attention toward novel stimuli and change, which the internet and technology constantly provide. We never know when we’ll receive a tweet or email or what they will be about, or what we’ll find browsing the internet. There is a never ending stream of new, complex information entering our brains at all times, and this has fundamentally changed the way the modern brain works.

Recent studies are showing that the structure of our brains can actually physically change from excessive Internet usage. A study in China looked at brain MRIs of college students who spent about 10 hours a day online, and compared them to a control group who spent under two hours a day online. The heavy internet users had noticeably less gray matter, which is involved in muscle control, sensory perception, memory, emotions, and speech. Another study showed that multitasking on the Internet was associated with a diminished ability to identify emotions in pictures of faces. Other studies have found correlations between excessive internet use and ADHD, social anxiety, and depression.

The increased use of the internet and technology is linked to spending more time sitting and living a more sedentary lifestyle in general, both of which are associated with significant health consequences, such as reduced lifespan, higher incidence of major diseases such as heart attack  and stroke, as well as a faster decline in cognitive functioning.

Although there is still some debate, research is coming around to support the idea of “Internet Addiction” as a disease like drug or alcohol addiction. The behaviors and effects associated with being addicted to the internet or technology are very similar to those related to drugs or alcohol. The constant stimulation the internet provides can actually increase dopamine activity in the main pleasure center of the brain. People can develop tolerance, where the same amount of internet time that used to be satisfying no longer is, so more is required to get the same effect. Heavy internet users who quit “cold turkey” can actually have significant withdrawal symptoms, including physical tremors, anxiety and mood swings. Internet addiction can cause affective changes such as depression or irritability. Furthermore, heavy internet usage can disrupt social relationships. All of these are characteristic of the classical definition of an addiction.

As our world becomes more and more wired, it is important to take some time everyday to unplug. Turn off your blackberry and go outside, have a real face-to-face conversation or read a book. If the idea of being away from your technology fills you with a sense of dread, it may be a good time to kick the habit.  If you think you may have an addiction or problem with excessive internet or technology use, take this online test (irony noted) to see how you rank. If you need help, there are counselors who work specifically with technology addiction. Just Google it. No, seriously.

5 Tips for Recovering from Summer Sun Damage

Summer is coming to an end, and while your tan looks great, those all day sun sessions may have taken a toll. Signs of sun damage may include dryness, prolonged redness, new freckles or moles, dull appearance and under-eye circles. Over time, sun exposure can lead to premature signs of aging, such as fine lines and wrinkles.

1. Exfoliate

Start with a clean slate! Being out in the sun all summer has most likely left you with an accumulation of layers of dead skin, giving your face a dull complexion. Using a gentle exfoliant 2-3 times per week to slough off dead skin cells will help to restore your skin’s natural radiance and glow.

2. Moisturize

Use a non-comedogenic moisturizer daily and drink plenty of water to restore your skin’s natural hydration. Use aloe vera to help with burning and to restore moisture. Aloe has natural anti-inflammatory properties, and has been shown to help burn patients heal nine days faster on average.

3. Protect

The most important (and often overlooked) component of an anti-aging regimen for your skin is the daily use of sunscreen. The sunscreen should be at least SPF 30 and protect against both the UVA and UVB spectrums.

4. Watch Your Diet

Several different foods will benefit your skin and help restore damage. Including soy in your diet aids in smoothing and moisturizing the skin, improving its overall tone. Antioxidant rich foods fight free-radical damage from the sun, working to repair previous damage and protecting against future damage.

5. Get Some Rest

Sufficient sleep is essential for healthy skin cell growth and repair, because it prompts skin cells to restore themselves and encourages the body to rebuild collagen. Getting at least 7-8 hours of quality sleep per night can maintain a healthy level of cell turnover and slowly diminish the signs of sun damage.

Still need more help? 

For excessive or prolonged sun damage or additional aesthetic enhancement, various cosmetic procedures may be an option. These include Chemical Peels, Laser Treatments, and Microdermabrasion for toning and resurfacing the skin, and Fillers and Collagen Stimulators for treating signs of aging that sun damage may accelerate, such as fine lines and wrinkles.

Happiness Holds the Key to a Long, Healthy Life

Laughter may really be the best medicine after all! A growing body of research is providing more and more evidence to support a powerful link between levels of happiness and overall health. Positive thinking individuals may be more likely to take better care of themselves and make better lifestyle choices, but researchers believe that positive thinking itself may have a direct biological impact. Here are just a few reasons to smile:

• Research has shown that people who rate higher in happiness are less likely to catch a cold than unhappy people. If they do catch a cold, happy people report fewer symptoms than unhappy people.
• A recent study by the American Heart Association revealed that adults over 50 who were more optimistic had a dramatically reduced risk of a stroke. The patient’s optimism was rated on a 16-point scale. For every 1 point increase on the scale, the patient’s stroke risk was reduced by 9%.
• A study involving nuns revealed a dramatic link between happiness and longevity. 90% of the nuns rating in the top quarter of cheerfulness were alive at age 85. Only 34% of the nuns in the bottom quarter were still alive at 85. 54% of the most cheerful nuns were alive at 94, whereas only 11% of the least cheerful lived to that age. Another study showed that optimists had a 19% longer life span on average.
• A study at Columbia University rated happiness levels of over 1,700 adults with no heart problems. After a decade, the researchers found that happier people were significantly less likely to develop a heart problem.
• A world wide study surveying 140 different countries revealed that the link between positive attitude and good health may be even stronger among impoverished nations. In so called “Third-World” countries with low life expectancy, harsh living conditions, prevalent hunger, and limited access to modern medicine, overall happiness and optimism played a larger role in determining life expectancy and disease prevalence than it did in industrialized nations.

Greater levels of happiness and related characteristics are associated with lower levels of chronic stress, which can lower immunity and increase inflammation, contributing to a staggering number of illnesses.  High levels of chronic stress are associated with increased susceptibility to depression, diabetes, hair loss, hyperthyroidism, obesity, obsessive-compulsive disorder, sexual dysfunction, ulcers, and several types of cancers. Some studies suggest that as many as 90% of symptoms that patients seek doctor’s visits for are at least partially related to stress. A study showed that happier people had lower cortisol (stress hormone) levels and happier men had lower heart rates.

So whether you’re improving your health by exercising and eating right,  losing weight,  quitting smoking, or making any number of positive lifestyle choices, don’t forget to smile and do the things that make you happy. It will improve your health, how long you live, and the quality of your life itself.

MEN, RED MEAT & PROSTATE CANCER

…SO WHAT’S THE PROBLEM?

Aren’t “real” men supposed to love red meat?  The media hypes it big time with rugged cowboys supposedly thriving on it, right? WRONG!  I hate to burst your bubble but red meat, processed meats and prostate cancer go hand in hand.  I’ve been following the studies and can confidently report to you today that the results are pretty conclusive.  One large study involving over 17,000 men ages 50 to 71 (over 9 years) found that those men who ate the most red and processed meats had significantly elevated risk of developing prostate cancer at any stage and, particularly, advanced cancer.

 RED MEAT & GRILLING/BARBEQUEING

I know you don’t want to hear it but …. The researchers found a direct link to grilling and BBQ’d red meats and prostate cancer.  They believe the link involves high-heat cooking and the chemicals it produces, namely polycyclic hydrocarbons (PAHs) and heterocyclic amines known to cause cancer in animals.

 Sorry guys!  My mission in life is to bring you health and wellness and I’m convinced it’s not found in red and processed meats.

 How about we talk about some other healthy options…

 Let me hear from you!

Excess Body Fat = Thousands of Cancer Cases Annually

A shocking new study was published last week by researchers with the American Institute for Cancer Research,  that states more than 100,000 cases of cancer are caused annually by excess body-fat and obesity. The researchers studied seven cancers with known links to obesity along with actual case counts that were likely obesity-related.

From

The report says that 49 percent of endometrial cancers are caused by excess body fat. That number is followed by 35 percent of esophageal cancer cases; 28 percent of pancreatic cancer cases; 24 percent of kidney cancer cases; 21 percent of gallbladder cancer cases; 17 percent of breast cancer cases; and 9 percent of colorectal cancer cases.

“This is the first time that we’ve put real, quantifiable case numbers on obesity-related cancers,” said Glen Weldon, the American Institute for Cancer Research educational director. In addition, he said, it’s not just causing cancer that’s an issue.

“Obesity not only raises the risk for getting cancer,” Weldon said. “It also has a negative effect on survival and can make treatment more difficult.” (Link to full story)

The sheer magnitude of this is a bit overwhelming, and calling attention to the problem is certainly necessary. In addition to cancer, we know obesity-related health problems abound, including heart disease, diabetes, high blood pressure, strokes and various other maladies. As I’ve explained before, increased body fat can lead to increased cellular inflammation, which is linked to DNA mutation and diseased cell growth, as is seen in cancers and many other diseases.

Unfortunately, the study doesn’t propose any solution. While some would suggest simply losing the weight, or not gaining it at all, I can’t help but add “keeping your soup clean” – i.e. not just counting calories, but eating a nutritionally dense and healthy diet and adopting an active lifestyle are paramount to good health.

Thanks for reading,

Andre Berger, M.D.
