A comparison of organic and conventional strawberry farms found that organic farms produced more flavorful and nutritious berries. They also left the soil healthier and more genetically diverse.

The study was among the most comprehensive of its kind. It analyzed the taste, nutrition and quality of three strawberry varieties on dozens of fields, and tested soil DNA along with 31 chemical and biological soil properties.

According to Eurekalert:

• The organic strawberries had significantly higher antioxidant activity and concentrations of ascorbic acid and phenolic compounds.
• The organic strawberries had longer shelf life.
• Anonymous testers ... found one variety of organic strawberries was sweeter, had better flavor, and ... appearance. The testers judged the other two varieties to be similar.

Mercola.com, by the way, is currently working on creating a gardening site to encourage more home gardens. Always remember that you can grow delicious organic strawberries yourself!

When he was a year and a half old, Kyle Warren started taking a daily antipsychotic drug. Over the years, he was diagnosed with autism, bipolar disorder, hyperactivity, insomnia, and oppositional defiant disorder, and put on more drugs each time. By the time he was 3, he was drooling and sedated. Today, he is off most of the drugs and doing fine.

More than 500,000 children are now taking antipsychotic drugs. A study recently found that the rate of antipsychotic drugs prescribe to privately insured 2 to 5 year olds had doubled between 2000 to 2007. Only 40 percent of them had received a proper mental health assessment.

The New York Times reports:

“... [M]any doctors say prescribing them for younger and younger children may pose grave risks to development of both their fast-growing brains and their bodies. Doctors can legally prescribe them for off-label use, including in preschoolers, even though research has not shown them to be safe or effective for children.”

Researchers have identified the molecular mechanism that makes omega-3 fats effective in reducing chronic inflammation and insulin resistance.

The scientists identified a key receptor on macrophages found in obese body fat.  Omega-3 fats activate this macrophage receptor, resulting in anti-inflammatory effects and improved insulin sensitivity.

Eurekalert reports:

“Macrophages are specialized white blood cells that engulf and digest cellular debris and pathogens. Part of this immune system response involves the macrophages secreting cytokines and other proteins that cause inflammation ... Obese fat tissue contains lots of these macrophages producing lots of cytokines. The result can be chronic inflammation and rising insulin resistance”.

According to results of a study, selenium intake is associated with decreased risk of bladder cancer.

Selenium is an essential micronutrient found in about 25 proteins. Most of these so-called selenoproteins are enzymes with antioxidant properties. The main dietary sources of selenium are plant foods grown in selenium-rich soils and animals who graze on such plants.

According to Eurekalert:

“The researchers noted a significant protective effect of selenium, mainly among women, which they believe may result from gender-specific differences in the mineral's accumulation and excretion in women.”

Allergan, which manufactures the cosmetic medication Botox, has agreed to pay $600 million to settle a federal investigation into its marketing of the botulin-based drug.

The company will plead guilty to one misdemeanor charge of "misbranding" – meaning the company's marketing led physicians to use Botox for unapproved uses. These uses included treatment of headache, pain, spasticity and cerebral palsy in children.

According to ABC News:

“Allergan said it will pay $375 million in connection with the plea, which includes the forfeiture of $25 million in assets. Additionally, the company will pay $225 million in civil fines -- $210 million to the federal governments and the rest to several states -- related to the investigation, although the company denies liability for the civil claims.”

A new study links the popular weight loss drug Meridia to an increased risk of heart attacks and stroke.  According to the authors of the trial, which was funded by Meridia's maker, the findings are generally in line with what was already known about the drug.

Since January, Meridia has carried a label warning that it should not be used by people with preexisting heart disease.

Business Week reports:

“ The U.S. Food and Drug Administration is slated to meet in September to decide if more regulatory action -- perhaps a tougher ‘black-box’ warning or even removing Meridia from the market -- should be taken ... The drug did not seem to make people healthier ... Some people were actually made worse”.

The reasons why muscles wither with age is a problem that is intriguing a growing number of scientists. Drug companies are trying to develop drugs that can build muscles or forestall their weakening, while food companies are exploring nutritional products with the same objective.

Both doctors and patients need to be more aware that muscle deterioration is a major reason the elderly lose mobility.

According to the New York Times:

“... [S]arcopenia [age-related loss of muscles] affects about 10 percent of those over 60, with higher rates as age advances ... Causes of the loss of muscle mass or strength might include hormonal changes, sedentary lifestyles, oxidative damage, infiltration of fat into muscles, inflammation and resistance to insulin.”

The best approach to restoring or maintaining muscle mass and strength is exercise. I would recommend trying Peak Fitness, a term I am coining to represent a comprehensive exercise program that includes far more than typical cardio training. The major change is that once or twice a week you do peak exercises, in which you raise your heart rate up to your anaerobic threshold for 20 to 30 seconds, and then you recover for 90 seconds.

You would repeat this cycle for a total of eight repetitions. We call it "peak fitness" because if you graph your heart rate, you will see that it peaks 8 times during the workout. One of the major reasons I am so enthusiastic about peak fitness is that it can actually increase your growth hormone level. This dramatically improves your muscle tone, and has many other beneficial effects as well!

Today, there are more training tools available for personal trainers than ever. How do you decide what equipment is best to use? Well, that really depends on the situation.

Let’s take resistance training, for example.

As far as I’m concerned, free weights reign supreme! Every time I’m asked what I think of this machine or that machine, my response is always the same: get yourself a simple barbell and dumbbell set with an adjustable bench and forget the rest. Period.

Many trainers find themselves in a situation where space and budget are limited, though, and free weights may not be the best option. Remember, resistance can come from many different sources.

Pros and Cons of Resistance Tubing and Bands

One such source that is quite popular in the field of personal training involves resistance tubing and bands.

These are portable devices that are relatively inexpensive and quite versatile. You can perform just about any exercise with a tube and they even come in different resistances (they are usually color-coded for this reason.)

With so many benefits, resistance tubes seem like the perfect training tool…except for a slight problem: If using elastics and one end is fixed, it creates resistance patterns that do not ideally match the torque-joint angle curves of your body because the bands increase resistance fairly linearly throughout the range.

The following two charts show the difference in muscle tension between free weight resistance and resistance tubing.

Adapted from Hartmann & Tunnemann, Fitness and Strength Training for All Sports, 1995, pg. 51

Fig. 1 — Bell-shaped ascending-descending strength curve displayed with free weight resistance.

Fig. 2 — Linear ascending strength curve displayed with resistance tubing.

Alright, so what’s the big deal if resistance tubing causes a linear ascending strength curve?

Well, the answer to that is simple: tubing encourages the disproportionate development of accelerators versus decelerators, and that my friends, can lead to injury (for a visual demonstration visit http://www.youtube.com/watch?v=LysSUBMqKnc).

In fact, out of 16 cases of rotator cuff tendonitis reported by the national synchronized swim team of Canada, all but one case were corrected by eliminating tubing and using dumbbells instead.

Tubing exercises are quite popular in the rehabilitative setting to train the rotator cuff muscles, but obviously, there is a big difference between using dumbbells and elastics.

To take it one step further, when performing shoulder external or internal rotations for example, dumbbells provide a greater overload in the bottom position and tubes provide a greater overload in the top position. You can combine the two during a set (i.e. hold onto both a dumbbell and tube) or use a cable to provide a relatively even overload throughout; however, two problems exist with these methods:

1. Assuming that you have access to a cable apparatus (many home gyms do not), most weight stacks start at 10 pounds, which is far too heavy for the average person.
2. It is difficult to adjust for individual leverages and fatigue, but there is a way…

This is where the concept of accommodating resistance applies, and it is so versatile with a tube or band — it can be used on almost any exercise!

The Concept of Accomodating Resistance to the Rescue

Here is a little trick I learned from the late Dr. Mel Siff. Basically, the concept is simple: use an exercise tube or band and have a partner follow the movement pattern to accommodate strength (i.e. give more or less resistance when needed.) Just remember to keep the movement smooth. When applying passive resistance, it’s not a competition!

That’s all there is to it.

With this novel technique, a serious flaw of training with elastics is rectified. All of a sudden, more pros and less cons!

Pros

• No sophisticated equipment is required.
• Can produce a more even strength curve.
• Can increase time-under-tension (TUT) to desired length – terminate set once particular TUT is achieved.

Cons

• Requires a training partner.
• Lack of objectivity (this can be offset somewhat by recording size of tube and distance of hand position.)

Examples

Let’s examine some shoulder movements using accommodating resistance with tubes.

Holistic Health Practitioner and Neuromuscular Therapist, Paul Chek, has a famous motto: “First Isolate, Then Integrate!” So with that said, let’s start with some isolation exercises.

Isolation Exercise for the Subcapularis Muscle

Some authorities feel that the subcapularis is the missing link to unlocking true strength of the upper extremities and improving shoulder strength and health. Many therapists often claim that this muscle tests weak and should be subsequently trained.

Well, the reason for this is due primarily to poor posture, or more specifically, rounded shoulders (i.e. a kyphotic posture) that is so prevalent in today’s society. This is a case of a tight and weak muscle.

Due to an extreme amount of internal rotation, the subscap (an internal rotator of the humerus) becomes extremely tight and facilitated. Since the sarcomeres (actin and myosin) experience full interdigitation, it becomes difficult to contract any further.

Therefore, in order to strengthen these fibers, they must first be placed in an optimum position to contract effectively – you accomplish that goal with appropriate stretching and myofascial release (e.g. A.R.T.)

Only after this is accomplished should the subscapularis be trained with resistance.

Isolation Exercise for the Infraspinatus Muscle

Another muscle that tests weak is the infraspinatus, an external rotator of the humerus, but for different reasons than above. It is usually long and weak – the actin and myosin filaments are not in optimum position for maximum force output. This particular rotator cuff muscle has appeared often in recent literature due to the lack of shoulder external rotation in many strength training programs creating a muscle imbalance.

Robert Lardner, a European Physical Therapist trained by among others Janda, reveals an interesting concept for rotator cuff exercises:

“To grab a dumbbell requires flexion of the arm muscles. The flexion muscles are so strong that these phasic (flexion) muscles will override the extensor (tonic) muscles. So all the guys lying on their sides are really doing mostly a bicep/brachia movement.So, what is the proper way to exercise these muscles?The best way is to have your hand open with your fingers spread and have the resistance strapped to your wrist, either through a rubber band or a cable. Then go through the extending motion that you wish to exercise."

It may indeed be more effective to perform many of the exercises listed in this article with an open hand. Try it and see if you can notice a difference.

Proper Execution of the ‘Pullover’ Exercise

Let’s move on to another common shoulder movement, the pullover. Many trainers prescribe this exercise to correct a winging scapulae.

Guess what? That is the wrong approach!

In order to remedy this situation, the serratus anterior, rhomboids and middle/lower trapezuis should be trained.

The pullover does not effectively target these muscles; in fact, it hits the specific muscles (particularly the latissmus dorsi and subscapularis) that cause winging scapulae (Polquin, 1997).

Furthermore, the dumbbell pullover is often performed over a bench. This method is inviting an abdominal hernia as well as overstressing the shoulder joint (especially if the trainee has tight shoulders!)

A far better approach is to perform the exercise on a decline bench or on the floor as depicted below to avoid maximum overload on the shoulder joint in extreme extension. In other words, by shortening the range of motion, it is safer for your shoulders. Also, avoid excessively arching your back by pressing your spine into the bench or floor and keeping your core tight throughout. Hence, your abdominals must act as stabilizers during the movement.

Integration Exercises

Proprioceptive neuromuscular facilitation (PNF) patterns are a series of movements developed by Herman Kabat and featured in a classic text by Knott & Voss. Although many trainers and therapists perceive PNF as a form of stretching, it is much more than that – it involves a series of spiral movements that cross the midline of the body. In doing so, all planes are crossed: vertical/horizontal extension/flexion, abduction/adduction, and internal/external rotation occur in one movement.

By using accommodating resistance with bands and tubes, you remove a major flaw associated with elastic resistance to provide a more even strength curve throughout the range of motion.

Instead of a rather inferior training tool, you now have a potent weapon at your disposal!

A new study has found that that eating a diverse diet of vegetables and fruit can decrease your risk of developing lung cancer.

Scientists looked at the health information of more than 450,000 people. Researchers compared participants' diets, and found that regardless of the amount, the risk of lung cancer decreased when a variety of vegetables and fruits were consumed.

According to Paging Dr. Gupta:

“In addition, the risk of squamous cell carcinoma, which is common in smokers, decreased substantially when a variety of fruit and vegetables were eaten.”

A study has discovered that the use of bariatric (weight loss) surgery has increased ten-fold in hospitals in England since 2000.  One reason for this rapid rise is increased demand from obese patients.

Bariatric surgery is performed on people who are dangerously obese. Techniques include gastric banding, gastric bypass, or sleeve gastrectomy, which reduce the size of the stomach in various ways.

According to Science Daily:

“A total of 6,953 bariatric procedures were carried out during the study period. The number of procedures rose more than ten-fold from 238 in 2000 to 2,543 in 2007.”

Researchers took a look at 12 genetic variants known to increase the risk of obesity, and then tracked the physical activity levels of more than 20,000 people. They determined that physical activity can reduce the genetic tendency toward obesity by 40 percent.

Even being active just 30 minutes a day proved to be a good start in reducing the effects of the genes.

USA Today reports:

“U.S. experts say the study adds to the data on the importance of exercise for weight control. ‘This is more evidence that behavior can modify genetic predisposition,’ says Tim Church, director of preventive medicine research at the Pennington Biomedical Research Center in Baton Rouge.”

Germany has banned all cultivation of MON 810, a form of GM corn. However, their arguments against it might not stand in court, and they could face millions of euros in fines if Monsanto decides to challenge the prohibition.

Under the new regulations, the cultivation of MON 810, a GM corn produced by Monsanto, would be prohibited in Germany, as would the sale of its seed. German Agriculture Minister Ilse Aigner told reporters she had reasons to believe that the corn posed “a danger to the environment.”

Break the Matrix reports:

“[Aigner] stressed that the ban should be understood as an ‘individual case’ and not as a statement of principle regarding future policy relating to genetic engineering.”

Two high-fat diets can reduce and sometimes completely eliminate seizures in children with a common disorder known as absence epilepsy.

A report shows that more than 70 percent of the patients treated with either a ketogenic or modified Atkins diet experienced at least 50 percent fewer seizures. Many showed as high as 90 percent improvement.

According to Newswise:

“The ketogenic diet has been used since 1921 to successfully treat several forms of epilepsy ... Made up of high-fat foods and few carbohydrates, the diet works by triggering biochemical changes that eliminate seizure-causing short circuits in the brain’s signaling system.”
