How Inactivity Harms Your Health

I came across this nifty diagram showing how being inactive contributes to illness. Get moving to stay healthy! When you don't move you gain weight, especially around the middle. White blood cells from your immune system move into the fat around your organs. This ignites inflammation everywhere in your body, which leads to insulin resistance and more weight gain, and ultimately diabetes. This raises your risk for heart disease, high blood pressure and stroke. This inflammation also leads to brain issues like dementia, Parkinsons and Alzheimers. Also increased is your risk for cancer. It is worth saying again. Get moving to protect your health!

Want to really improve your chances of preventing heart disease?

Learn how lifestyle factors cut your risk. Here they are:

1. Not smoking cigarettes 

2. Not being obese (having a B.M.I. less than 30) 

3. Performing physical activity at least once a week. 

4. Having a healthful diet pattern.

Here is what defines a healthful diet pattern. Do at least half of these things: eat more fruits, nuts, vegetables, whole grains, fish and dairy products; eat less processed meats, unprocessed red meats, sugar sweetened beverages, trans fats and sodium.

Every one of the four lifestyle factors was associated with a decreased risk of coronary events.

That’s the first bit of good news. Doing any one of these things makes a difference.

But the effect is cumulative. The researchers divided people into three groups based on these factors. “Favorable” required at least three of the four factors, “intermediate” required two of them, and “unfavorable” required one or none. Across all studies, those with an unfavorable lifestyle had a risk that was 71 percent to 121 percent higher than those with a favorable lifestyle.

More impressive was the reduction in coronary events — heart attacks, bypass procedures and death from cardiovascular causes — at every level of risk. Those with a favorable lifestyle, compared with those with an unfavorable lifestyle, had a 45 percent reduction in coronary events among those at low genetic risk, a 47 percent reduction among those with intermediate genetic risk, and a 46 percent reduction among those at high genetic risk.

What does this mean in real-world numbers? Among those at high genetic risk in the oldest cohort study, 10.7 percent could expect to have a coronary event over a 10-year period if they had an unfavorable lifestyle. That number was reduced to 5.1 percent if they had a favorable lifestyle. Among those at low genetic risk, the 10-year event rate was 5.8 percent with an unfavorable lifestyle and 3.1 percent with a favorable lifestyle. In the other cohort studies, similar relative reductions were seen.

These differences aren’t small. The risk of a coronary event in 10 years was halved. The absolute reduction, more than 5 percentage points in the genetic group at high risk, means that lifestyle changes are as powerful as, if not more powerful than, many drugs we recommend and pay billions of dollars for all the time.

There are important lessons to be learned. These results should encourage us that genetics do not determine everything about our health. Changes in lifestyle can overcome much of the risk our DNA imposes.

Lifestyle changes are hugely important not only for those at low risk, but for those at high risk. The relative reductions in events were similar at all levels of genetic risk.

Remember that changes in lifestyle also reduce your risk of cancer, the number two killer making it clear that a healthy lifestyle has implications for an even greater number of us!

Making Choices that Slow Aging Significantly

Have you heard about telomeres? At the end of your chromosomes or DNA strands, you have protective caps called telomeres (imagine the little caps at the end of your shoelaces).

The length of your telomeres can tell you either how quickly or how slowly you are aging. Telomeres also shed light on the strength of your immune system. Their length indicates your risk of death and disease, including heart disease and cancer. Having short telomeres even points to higher risk of dementia.

In people who are older than 60 researchers have shown that those with shorter telomeres are eight times more likely to die from infectious diseases and three times more likely to die from heart disease. Although all telomeres shorten with age, an unhealthy lifestyle is linked to significantly greater telomere shortening. Researchers studying telomeres believe that lifespan may be increased by as much as five to ten years by changing habits that impact telomere length. Here are the most important choices you can make to protect your telomeres.

Knock out inflammation, and eat an antioxidant rich diet.

Chronic inflammation and oxidative stress caused by free radicals sabotage health, longevity and telomere length. Eating foods that contain lots of antioxidants and anti-inflammatory compounds helps prevent this double whammy of damage.

Be sure your diet includes abundant colorful fruits and vegetables like berries, cherries, pomegranates,  beets, oranges, and apples. And load up on dark green vegetables like collard greens and kale. Choose daily servings of orange veggies like carrots and sweet potato. And enjoy nuts, seeds, beans, fatty fish (salmon, rainbow trout, sardines), herbs, spices, 100% whole grains. Drink green or black tea and cook at low temperatures with extra virgin olive oil.

In terms of supplements, research suggests that vitamin D may improve telomere maintenance. Know your vitamin D levels by getting them checked at your annual check up. In the Sister Study, a daily multivitamin was also linked to longer telomeres in women. And of course if you don’t eat fatty fish at least twice a week, you should take a daily fish oil capsule. In the Heart And Soul study at the University of California, San Francisco involving over 600 outpatients with stable heart disease, individuals with the lowest intakes of marine source omega-3 fats experienced the most rapid rate of telomere shortening, whereas those with the highest intakes experienced the slowest rate of telomere shortening. Be sure you get at least 1000 mg daily of the EPA and DHA from cold water fish. And be sure the supplement you choose is tested and found to be free of harmful levels of compounds like mercury, lead, cadmium and PCBs. My fish oil brand is Carlson Laboratories.  Disclosure: I am their Senior Nutritionist and Educator. The folks at Carlson are seriously nice people, lucky me.

Eliminate added sugar, white bread, unhealthy fats and processed meat.

Some foods slow the aging process, others put aging on the fast track. Sugar, refined carbohydrates including white bread cakes cookies and crackers, unhealthy fats particularly trans fats and high omega-6 vegetable oils and processed meats are the most harmful. Based on data from the U.S. National Health and Nutrition Examination Survey involving over 5300 adults, drinking one sugar- sweetened soft drink daily accelerated aging as much as smoking. In a study of children and teens in Spain, white bread was the worst habit. In a study in Finland, involving almost 2000 elderly men and women, a high intake of saturated fat was linked to shorter telomeres.

Do whatever you must to stay at a healthy weight for your height.

At St. Thomas Hospital in the UK, obese women had telomeres that were significantly shorter than in lean women of the same age. This was not surprising. Fat cells are biologically active, and not in a good way. Fat secretes hormones that increase inflammation in the body and cause oxidative stress. ( Oh those two again!) Thus telomeres shorten, aging hits the gas pedal, and lifespans are shortened. Eat whole foods, be more active and work to reduce stress to keep your weight within a healthy range.

At the risk of being redundant. Stay active and reduce sitting time.
Moving your body several times everyday provides phenomenal health benefits, not the least of which is slamming the brakes on aging considerably. Daily activity boosts your resistance to infections, guards against chronic inflammation and helps to combat stress. You’ll get slim and you’ll be protecting the length of those all important telomeres. In one study that followed 2,400 twins, being regularly active during leisure time meant significantly longer telomeres (about 10 years younger biologically) compared to persons who were inactive.

Get up out of that chair! How much time you spend sitting also matters. In a 6 month study in Sweden, involving sedentary, overweight men and women, reducing sitting time resulted in significantly longer telomeres. Always aim for a minimum of 30 to 60 minutes of moderate to vigorous activity each day. Break up sitting time throughout the day and evening too. Sitting equals aging. Here’s an idea. Get up every 30 minutes and drink a small glass of water. (see what I did there?)

Watch your alcohol and never smoke cigarettes. If you smoke now is the time to quit.
Have you ever looked at people who smoke regularly or who drink excessively? They do not paint a pretty picture. They always look older than they should for their age. Heavy drinking and smoking ages you at a cellular level. The American Association for Cancer Research reported that telomere length was dramatically shorter (about half as long) in those who consumed heavy amounts of alcohol compared to those who did not. In a study reported in the UK, telomere shortening caused by smoking one pack of cigarettes a day for 40 years was equivalent to the loss of almost 71⁄2 years of life. Bottom line: don’t smoke and if you drink, do so only in moderation (one drink daily for women and two for men).

Defend your quality of sleep vigorously. Getting enough sleep (7 hours or more) and getting good quality sleep are both linked to longer telomeres. The older you are, the more significant this relationship is. Proper sleep helps repair telomeres and protects against damage caused by inflammation. Lack of sleep increases inflammation in the body significantly.

Zen extends life. If you’re chronically stressed out, anxious, lonely or depressed, your telomeres are probably shorter. If you have recently suffered a great loss, you’re also at risk. Stress hormones, like cortisol, make you gain weight around the middle, think belly fat. The hormone also damages cells and hastens aging. In a study involving healthy premenopausal women, those with the highest levels of perceived stress had telomeres shorter on average by the equivalent of at least 10 years of additional aging compared to low stress women. 

In a demonstration of all of the points made here today, a UC study found that telomere shortening was less pronounced  in high stress women if they exercised, ate well and got enough sleep. Good self-care must be a priority. 

There is also good news for meditators. Meditation also benefits telomere health. Om.

High HDL Cholesterol Levels Associated With Reduced Alzheimer’s Risk

High levels of high-density lipoprotein (HDL), also known as “good” cholesterol, appear to be associated with a reduced risk for Alzheimer’s disease in older adults.

”Dyslipidemia [high total cholesterol and triglycerides] and late-onset Alzheimer’s disease are highly frequent in western societies,” the authors write as background information in the article. “More than 50 percent of the U.S. adult population has high cholesterol. About 1 percent of people age 65 to 69 years develop Alzheimer’s disease, and the prevalence increases to more than 60 percent for people older than 95 years.”

Christiane Reitz and colleagues studied 1,130 older adults to examine the association of blood lipid (fat) levels with Alzheimer’s disease. The study included a random sampling of Medicare recipients 65 or older residing in northern Manhattan, with no history of dementia or cognitive impairment. The researchers defined higher levels of HDL cholesterol as 55 milligrams per deciliter or more.

To determine this association, data were collected from medical, neurological and neuropsychological evaluations. Additionally, the authors assigned a diagnosis of “probable” Alzheimer’s disease when onset of dementia could not be explained by any other disorder. A diagnosis of “possible” Alzheimer’s disease was made when the most likely cause of dementia was Alzheimer’s disease but there were other disorders that could contribute to the dementia, such as stroke or Parkinson disease.

During the course of follow-up, there were 101 new cases of Alzheimer’s disease, of which 89 were probable and 12 were possible. The mean (average) age of individuals at the onset of probable and possible Alzheimer’s disease was 83 years, and compared with people who were not diagnosed with incident Alzheimer’s disease, those who did develop dementia were more often Hispanic and had a higher prevalence of diabetes at the start of the study. Higher plasma levels of HDL cholesterol were associated with a decreased risk of both probable and possible Alzheimer’s disease, even after adjusting for vascular risk factors and lipid-lowering treatments. Although higher plasma total cholesterol, non-HDL cholesterol and LDL cholesterol levels also were associated with decreased risks of probable and possible Alzheimer’s disease, these associations became non-significant after adjusting for vascular risk factors and lipid-lowering treatments.

“In this study, higher levels of HDL cholesterol were associated with a decreased risk of both probable and possible Alzheimer’s disease,” the authors conclude. “An important consideration in the interpretation of the results is that it was conducted in an urban multiethnic elderly community with a high prevalence of risk factors for mortality and dementia. Thus, our results may not be generalizeable to cohorts with younger individuals or to cohorts with participants with a lower morbidity [disease] burden.”

Strawberry Orange Ginger Smoothie

Fresh ginger gives this smoothie a refreshing and delicious taste.

The healing properties of ginger are similar to non-steroid anti-inflammatory drugs (NSAIDs), therefore, it can regulate biochemical pathways which are activated with chronic inflammation. Adding ginger to your daily diet can soothe the aches and pain associated with aging. If you wake up with stiff joints or sore hands, this smoothie in the morning may put a smile on your face.

Ingredients

~1 cup orange juice.

~1 cup Vanilla Almond Milk

~1 tsp grated ginger root

~1 cup fresh or frozen strawberries

In a blender, combine orange juice, milk, ginger root and berries. Puree until smooth. Serve cold.

Excellent source of vitamin C, potassium and anthocyanins (antioxidants in berries).

Tip: turn this into your daily serving of Omega-3 by adding a teaspoon of Carlson’s The Very Finest Fish Oil, Orange or Lemon Flavor. Adding the Omega-3 EPA/DHA rich oil boosts the ginger's inflammation balancing power and you'll be supporting heart, brain, and vision health too! And I assure you this taste award winning oil is never fishy. Try it you'll be hooked!

One Week of Junk Food May Be Enough to Damage Your Memory

Feed your brain the right foods.

A new study from the University of New South Wales in Australia published in the journal Brain Behavior and Immunity, shows that just one week of eating an unhealthy diet is enough to cause lasting memory impairment in rats.

For a week, the rats were given access to a bottle of sugar water in addition to a healthy diet, or were fed a cafeteria-like diet loaded with cakes, cookies, and fat. Although only the rats on the cafeteria diet gained weight, both groups of rats had memory impairments compared with control animals who ate only healthy foods, suggesting that weight gain alone wasn’t to blame for their memory lapses.

Poor Diet Damages the Hippocampus

The rats had little trouble with object recognition, a type of memory that involves a brain region called the perirhinal cortex. But they did far worse with place recognition, a type of memory that involves a brain region called the hippocampus, which is responsible for many types of memory formation, including retaining new facts.

In the rats on the high-sugar or cafeteria diet, the researchers found that the hippocampus had become inflamed, impairing its function. The inflammation and memory damage lasted for at least three weeks after the rats were returned to a healthy diet.

Although rats aren’t a perfect model for humans, their hippocampus functions in very similar ways to ours. In humans and rats, the hippocampus not only helps us learn but also helps us navigate places and record events as they happen. Keeping it healthy is invaluable for learning and recall.

“A healthy diet is critical for optimum function,” said study author Professor Margaret Morris in an interview with Healthline. “Our data suggests that even several days of bad diet may impair some aspects of memory.”

The hippocampus is also used to regulate the body’s stress system. If it’s not able to do its job properly, stress can get out of control, dumping hormones into your bloodstream that will circulate back to the hippocampus and damage your memory further.

To complete the vicious circle, when stress levels are high, the body’s hunger systems shift. This causes you to selectively crave fatty and sugary foods. 

Memory and Age 

Although a little junk food here and there won’t have too much impact on a young person, a lifetime of poor eating can add up. If your hippocampus doesn’t get a chance to recover from the sugary, fatty onslaught, the inflammation could become long-term damage.

“Some studies show a decline in cognition with aging, and it is possible that an unhealthy diet may be particularly unhelpful in this group,” said Morris. Older brains take longer to recover from insults such as hangovers, so they might also be more vulnerable to damage from a junk food diet.

As seniors living on their own lose mobility, some are more likely to eat pre-packaged foods, such as frozen dinners, which tend to be high in fat, sugar, and salt. So this finding might also help explain the role that diet plays in the development of memory impairment in diseases like Alzheimer’s.
