100 Life Saving Health Food Tips

[media id=21 width=500 height=400]

Health food is a term that has been used in the United States since the 1920s and refers to specific foods claimed to be especially beneficial to health.

In contrast to a regular healthy diet, proponents of health foods claim that particular foods have specific favorable effects on health. Examples of health foods include alfalfa sprouts, wheat germ and yogurt. Natural foods and organic food are related categories. Health foods are sold in health food stores or in the health/organic section of supermarkets.

The term is often used for foods that are low in fat and/or sugar, since overconsumption of fatty and sugary foods is seen as contributing to the obesity epidemic.

How broccoli can protect your arteries

How broccoli can protect your arteries

It’s long been thought that broccoli is good for your heart, and now British scientists think they know why.

Researchers at Imperial College London have found evidence a chemical in broccoli and other green leafy vegetables could boost a natural defense mechanism that protects arteries from the clogging that can cause heart attacks.

In a study funded by the British Heart Foundation charity and conducted on mice, the researchers found that sulforaphane — a compound occurring naturally in broccoli and other brassicas — could “switch on” a protective protein which is inactive in parts of the arteries vulnerable to clogging.

“We know that vegetables are clearly good for you, but surprisingly the molecular mechanisms of why they are good for you have remained unknown for many years,” said Paul Evans of the National Heart and Lung Institute at Imperial College.

“This study provides a possible explanation for how green vegetable consumption can promote a healthy heart.”

Scientists already know that arteries don’t clog up in a uniform way, but that there are bends and branches of blood vessels — where blood flow is disrupted or slower — which are much more prone to the build-up of fatty plaques that cause heart disease.

Evans said his research found that in the more vulnerable areas, a normally protective protein known as Nrf2 is inactive.

“What our study showed was that sulforaphane can protect those regions by switching on the Nrf2,” he said.

The research, reported in the journal Arteriosclerosis Thrombosis and Vascular Biology, was conducted using purified sulforaphane, not broccoli. Researchers said the next step was to test the effect of the chemical as it is found in vegetables.

We now need to go and test this with broccoli smoothies, as it were, and compare that with the effect of purified sulforaphane,” Evans said, adding that if the vegetable form proved less effective, there could be an argument for taking sulforaphane in pill form.

Resistance band exercises are widely used by a variety of health and fitness practitioners – both for general strength and conditioning and rehabilitation or injury prevention.

Resistance band exercises are ideal for home exercise programs and can easily be incorporated into a circuit training format helping to condition cardiovascular system as well as strengthening specific muscle groups. Because resistance tubing is so compact and lightweight, it can be used while away from home.

Resistance tubing is extremely adaptable and a large number of resistance band exercises can be developed with very little additional equipment. Smaller muscle groups that are hard to train with more traditional free weight exercises can be targeted with resistance tubing. This makes it particularly appealing to athletic conditioning.

Sports-specific conditioning involves training movements rather than individual muscle groups. The versatility of resistance band exercises allows the athlete to mirror very closely the movement patterns in their sport with varying degrees of resistance. Perhaps even more important is the role they can play in injury prevention and rehabilitation.

Resistance Band Exercises for Injury Prevention & Rehabilitation

Few studies have examined the effects of resistance band exercises on strengthening a specific muscle group. As a result no definite guidelines exist as to the number of sets, repetitions and amount of resistance that should be used. However, many health and fitness practitioners use resistance tubing routinely to prevent and rehabilitate overuse injuries by strengthening often smaller, neglected muscle groups.

For example, athletic movements such as a baseball pitch can place considerable demand on the posterior rotator cuff muscles (external rotators, supraspinatus, infraspinatus, teres minor). These muscles undergo eccentric contraction during the declaration phase of the pitch  which places considerable strain on the shoulder . However, the same muscles may not be effectively worked with traditional isotonic exercises . If larger muscle groups, such as the deltoids, become stronger and are able to cope with and apply greater force, this may further compromise the rotator cuff muscles.

A program of resistance band exercises to compliment regular strength training may be able to improve the strength of more isolated muscle groups such as the rotator cuff . Additionally, training these otherwise neglected muscles may even improve performance.

Of course resistance band exercises can be used for more than simply strengthening more isolated muscle groups. The exercises below work the major muscle groups are only a small sample of the many hundreds of variations that have been devised.

Athletes may want to incorporate them into an off season training program when recovery and regeneration is the most important goal.

Resistance bands are available in a range of colors that relate to their stiffness or resistance. Color-coding varies between the brands but it typically as follows:

Yellow (thin)

Red (medium)

Green (heavy)

Blue (extra heavy)

Black (special heavy)

Silver (super heavy)
