What's Your pH

The concept of pH was first introduced by Dr. Sorensen at the Carlsberg Laboratory in 1909. pH stands for "potential of Hydrogen" which is the measure of hydrogen-ion concentration in a solution. pH is measured on a scale from 0 to 14 in reference to the acidity or alkalinity of a solution. In this context, the word "solution" simply means something mixed with water.

A pH of 7 is considered to be neutral - a pH of less than 7 is more acidic and a pH higher than 7 is more alkaline. If you mix acid with water, for example, the pH of the solution will be less than 7 - if you mix an alkaline with water the pH of the solution will be greater than 7.

In general - the latest research has associated many types of diseases and chronic conditions with a body that is more acidic than alkaline. The consensus of opinion indicates that the body should be slightly alkaline for optimal health.

The foods that we eat become mixed in solution with all of the water in our bodies. This is significant because our bodies are about 70% water. For optimal health, the pH of the body's fluid should stay within normal ranges. The normal pH balance in the human body is 7.35 to 7.45, which is slightly on the alkaline side of the pH scale.

If you have an interest in your body's pH balance, the first step is to find out what it is. Testing is easily done using pH testing strips with saliva or urine - these inexpensive testing strips are available at most pharmacies - they are also available online from many sources.

From there, it's a process of trial and error with respect to food and drink choices. We are all different and unique - so the choices that work for one person may not be the ideal choices for another.

The prevailing wisdom indicates that eating 75% alkaline foods and 25% acidic foods will keep your body at a healthy pH balance. When we talk about foods in this context, we're talking about the result in the body of eating the foods, not necessarily the pH of the foods themselves before we eat them.

Examples of alkaline foods include most fruits and vegetables along with water and vegetable juices. Acidic foods, in general, are meat, dairy, junk food, processed food, fast food, alcohol, drugs and medications. There are some exceptions in both directions so if you have an interest, we encourage you to search online for "alkaline foods" - after reviewing a few websites you'll have a better understanding concerning alkaline foods and acidic foods and some good guidelines to follow with respect to food choices.

Watch Your TV Time

Researchers from the Harvard School of Public Health (HSPH) and Children's Hospital Boston found that kids who spend more time watching television also eat more of the calorie-dense, low-nutrient foods advertised on television. Previous studies had demonstrated that children who watch more television are more likely to be overweight, but this is the first time a research team has found evidence for a mechanism explaining that relationship. The study results appear in the April 2006 issue of the Archives of Pediatric and Adolescent medicine. "We've known for a long time that television viewing is a risk factor for overweight, though the common perception is that this is due to the fact that it's a sedentary use of time," said Jean Wiecha, the study's lead author and a senior research scientist at HSPH. "This study provides evidence that television is effective in getting kids to eat the foods that are advertised, and this drives up their total calorie intake."

The results of the study showed that each hour of increased television viewing over baseline was associated with a total energy increase of 167 calories -- just about the amount of calories in a soda or a handful of snack food, said Wiecha. Each additional hour of television viewing was also independently associated with increased consumption of foods commonly advertised on television, and these foods were shown to be responsible for much of the calorie increase. Viewing time seemed to have the strongest connection to additional consumption of sugar-sweetened beverages.

Twice as many children and almost three times as many teens are overweight today compared to their counterparts growing up 20 years ago. Overweight young people are more likely to become overweight or obese adults who are at risk for diseases like diabetes and heart disease. The results of this study bolster a longstanding recommendation by the American Academy of Pediatrics to limit children to less than two hours of television each day to both lessen sedentary time and reduce exposure to content associated with negative consequences.

Stretching

Stretching is something you can easily do anytime, anywhere -- in your home, your office, or even when you're traveling. Aim to stretch at least three times a week. If you can't get a full workout in, you can still benefit from stretching at least that often. Many experts believe that stretching may also reduce your risk of injury in sports. "The more prepared your muscles and joints are for an activity, the more protected you are against injury," says Edward Laskowski, M.D., a physical medicine and rehabilitation specialist and co-director of the Sports Medicine Center at Mayo Clinic, Rochester, Minn. Dr. Laskowski explains, "If your joints are not able to go through their full range of motion because of muscle tightness, sports and exercise activities may put an excessive load on the tissue and contribute to injury."

The many benefits of stretching include:

Increased flexibility and better range of motion of your joints - Flexible muscles can improve your daily performance. Tasks such as lifting packages, bending to tie your shoes or hurrying to catch a bus become easier and less tiring. Flexibility tends to diminish as you get older, but you can regain and maintain it.

Improved circulation - Stretching increases blood flow to your muscles. Blood flowing to your muscles brings nourishment and gets rid of waste byproducts in the muscle tissue. Improved circulation can help shorten your recovery time if you've had any muscle injuries.
Better posture - Frequent stretching can help keep your muscles from getting tight, allowing you to maintain proper posture. Good posture can minimize discomfort and keep aches and pains at a minimum.

Stress relief - Stretching relaxes tight, tense muscles that often accompany stress. Maintaining the full range of motion through your joints keeps you in better balance. Coordination and balance will help keep you mobile and less prone to injury from falls, especially as you get older.

Basic stretches to improve your flexibility focus on your body's major muscle groups: calf, thigh, hip, lower back, neck and shoulder.

Warm up first. Stretching muscles when they're cold increases your risk of pulled muscles. Warm up by walking while gently pumping your arms, or do a favorite exercise at low intensity for five minutes.

Hold each stretch for at least 30 seconds. It takes time to lengthen tissues safely. Hold your stretches for at least 30 seconds -- and up to 60 seconds for a really tight muscle or problem area.

Don't bounce. Bouncing as you stretch can cause small tears in the muscle, which leave scar tissue as the muscle heals. The scar tissue tightens the muscle even further, making you even less flexible -- and more prone to pain.

Focus on a pain-free stretch. If you feel pain as you stretch, you've gone too far. Back off to the point where you don't feel any pain, then hold the stretch. Relax and breathe freely. Don't hold your breath while you're stretching. Stretch both sides. Make sure your joint range of motion is as equal as possible on each side of your body.

Stretch when you exercise or three times a week to maintain flexibility "Stretch as often as you exercise," Dr. Laskowski recommends. "Most experts recommend a cool-down period anyway after exercise. Going into your stretches after your workout is a good way to cool down.

Why not make stretching a family fun time with the kids as part of your family's daily wellness program?

Whole Foods & Male Fertility

At a recent American Society for Reproductive Medicine meeting, new research revealed that eating more fruits and veggies can help men boost their fertility. These new findings indicate that the more produce a man consumes, the healthier his sperm will be. In a study group of infertile men, 83 percent of them were found to be eating less than five servings of fruits and veggies a day. Overall, the men who ate the fewest fruits and veggies had the lowest sperm motility.

"We think that sperm quality is affected by dietary antioxidant intake," said study author Dr. Vivian Lewis, a professor of obstetrics and gynecology at the University of Rochester in Rochester, N.Y. "Antioxidants, like those found in fruits and vegetables, may help prevent damage to sperm that causes them to become sluggish and lose the ability to fertilize an egg".
In particular, the antioxidants glutathione and cryptoxanthin, which are prevalent in brightly colored produce such as leafy greens, tomatoes, peppers and oranges, were associated with strong, healthy sperm, Lewis said. She recommended that men hoping to father children eat "a variety of fruits and vegetables, at least five servings a day.

The modern day researches continue to confirm what the ancients knew. Focus on giving your body what it needs - it knows how to do the rest.

Lasting Vision

Many of us heard, as children, that carrots are good for our eyes. When questioned about this, moms would regularly retort with a well known question: "Well, have you ever seen a rabbit wearing glasses?" Carrots are certainly a potent whole food with many wonderful health benefits, but the latest research indicates that fruit is even more important for the nutritional support of your eyes and vision. A recent study published in the June 2004 issue of the Archives of Ophthalmology indicates that eating 3 or more servings of fruit per day may lower your risk of age-related macular degeneration (ARMD), the primary cause of vision loss in older adults, by 36%, compared to persons who consume less than 1.5 servings of fruit daily.

In this study, which involved over 70,000 women and over 40,000 men, researchers evaluated the effect of consumption of fruits; vegetables; the antioxidant vitamins A, C, and E; and carotenoids on the development of early ARMD or neovascular ARM, a more severe form of the illness associated with vision loss.

Food intake information was collected periodically for up to 18 years for women and 12 years for men. While, surprisingly, intakes of vegetables, antioxidant vitamins and carotenoids were not strongly related to incidence of either form of ARM, fruit intake was definitely protective against the severe form of this vision-destroying disease.

Active Kids Do Better in School

Middle school students who perform more vigorous physical activity than their more sedentary peers tend to do better in school, according to a new study done by researchers from Michigan State University and Grand Valley State University . The research is published in the August issue of Medicine & Science in Sports & Exercise, the official journal of the American College of Sports Medicine. For one academic year, the study tracked more than 200 sixth graders. For one semester half of the students took the general physical education class offered by the school, while the other half took part in a non-physical education course. Halfway through the school year they switched. The researchers found that students taking the physical education course did no better or worse in their academic classes.

"Physical education and activity during the school day reduce boredom and help keep kids' attention in the classroom," said Dawn Podulka Coe, the study's lead author who is now an assistant professor in the Department of Movement Science at Grand Valley State University . "We were expecting to find that students enrolled in PE would have better grades because of the opportunity to be active during the school day. But enrollment in PE alone did not influence grades."

However, the researchers also found that students who took part in more vigorous physical activities - such as organized sports like soccer or football, or non-organized after-school activities such as skateboarding - did approximately 10 percent better in core classes such as math, science, English and social studies.

"The students who performed better academically in this study were the most active, meaning those who participated in a sport or other vigorous activity at least three times a week" added Coe.

The difference between vigorous activity and moderate activity is heart rate. Moderate activities, such as walking or raking leaves, don't get the heart rate up or make the person breathe harder. Vigorous activities, such as running or swimming for exercise, increase heart rate, causing the exerciser to breathe harder and increasing oxygen to the brain.

We encourage parents to consider organized sports as a way to help your child do better in school, be healthier, maintain the proper weight, and to build a foundation of health that can last a lifetime.
