Citric Fruits – A Healthy Food
New studies suggested once again that citric fruits including oranges, tangerines, and grapefruits help fight cancer, high cholesterol, and obesity.
Studies both at Texas A&M University and Kanazawa Medical University in Japan showed that compounds in citric fruits can help reduce the risk of colon cancer. Researchers at Texas A&M University found that freeze-dried grapefruit, similar to the whole grapefruit, can reduce the incidence of early colon cancer lesions in animals. The Japanese researchers found anti-colon cancer properties in nobiletin – a compound found in tangerines.
Grapefruit can also reduce the risk of cancer caused by smoking. A study on the cancer prevention was done by the researchers at the University of Hawaii. The researchers found that drinking 6 ounces of grapefruit juice a day reduces the activity of a liver enzyme that is thought to activate toxic chemicals in the smoke.
On another front, scientists from the USDA and a Canadian company isolated a compound – polymethoxylated flavones (PMFs) – from orange and tangerine peels that can actually lower cholesterol in animals. They found that use of food containing 1% PMFs can lower cholesterol by 32 to 40%.
Grapefruits also promote weight loss. Researchers at Scripps Clinic in San Diego found that grapefruit may trigger weight loss by lowering insulin levels, an excess of which is linked to weight gain. Effect of grapefruits on weight loss was confirmed in humans. An early study by the same researchers confirmed that eating grapefruit or drinking juice with meal can help the obese lose weight.
Even the interaction of grapefruit juice with drugs, a bad trait for grapefruit, has been explored. Researchers at Texas A&M Citrus Center studied the interaction between grapefruit compounds and drugs in hopes that this interaction can be taken advantage of to increase bioavailability of drugs in humans.
These studies were presented in the American Chemical Society Annual Meeting being held in Pennsylvania during Aug. 22 through 26.

Myth: Gastric Bypass Patients Dont Need to Exercise to Lose Weight
Nothing is more disappointing than hearing a gastric bypass patient brag that they didn’t have to exercise to lose weight. It’s true; patients will lose weight without lifting a finger. In fact, for many, the lack of physical effort required to lose weight is an appealing part of weight loss surgery. But patients who do not use the time of rapid weight loss to incorporate exercise into their lifestyle are doing themselves a grave disservice.
Obesity cripples the body. Bone tissues are compromised, joints are swollen, the vascular system is inadequate and the skeleton overburdened. Some morbidly obese people are so crippled from carrying excess weight they are confined to wheelchairs and scooters. They yearn to walk painlessly through a park or museum. When pre-operative patients imagine life after weight loss surgery I suspect there is no wheelchair, scooter or walking stick in that dream. Patients dream of mobility and strength in their bodies.
As weight is lost, the burden on the bones, joints and vascular system is decreased. And the body is a magnificent machine – given proper nutrition and physical motion it will rebuild its broken framework. The systems will become strong and vital.
The most effective way to heal the body from the ravages of obesity is to exercise.
Patients don’t have to jump up from the surgical bed and run a marathon; in fact, they never have to run. But they have to move their body: walk, stretch, bend, inhale and exhale. Patients who want to take full advantage of weight loss surgery must engage in daily physical exercise.
Exercise, however defined, is the most effective, most enjoyable, most beneficial gift one can bestow on themselves while recovering from life threatening, crippling morbid obesity. Patients who initiate an exercise regimen quickly after surgery report long-term success at weight. Exercisers seldom report weight regain.
There has never been a better time to become fit. Exercise philosophy has changed. Gone are the days of "make it burn" and "no pain, no gain." Exercise experts say move your body 30 minutes a day, and the benefits will resonate throughout your being. Injuries are down and exhaustion isn’t the objective. Consistency is all that’s required. Fitness is no longer considered an exact science – we are given permission to find what works and enjoy it. Incorporate cardiovascular, flexibility and strength training into the exercise program: the three work in combination to help you become healthy, agile and maintain metabolism.
If quality of life is to be preserved – or restored – exercise is required. The body was designed to require a certain minimum level of physical activity. When physical activity is absent obesity results. Our bodies do not thrive when they are sedentary. It is therefore crucial to deliberately incorporate movement into our lives.
More than any other time in your life, following surgery the body is ready to respond to the benefits of physical motion. Surgery is the first step to better health and controlling obesity by restricting food intake. Following surgery is the golden opportunity to muster all the discipline possible and take a stand for a healthier, happier, longer and more productive life. Patients must exercise more than we have in the past and more than is convenient.
I implore patients, "Do not make the mistake of delaying your exercise program until the weight is gone. If you fail to exercise during the phase of rapid weight loss your skin will sag, your energy will lag and your metabolism will slow. Weight loss will be more difficult to accomplish. You will miss an opportunity to feel good about yourself as you set realistic fitness goals and achieve them. You will miss the euphoria from oxygenated cells. You will betray yourself."
