    Americans Eating Habits Worsen

    This news is sad - do you think there is a solution to healthy eating in America?

    I know that easy access to fast food is not our friend!

    No...not for the majority. They are simply unawares of their "addiction"...

    Rats Fed Junk Food Became 'Addicts'

    A new study found that rats that ate too much junk food developed the characteristics of an addiction to food, HealthDay reports . Rats fed a diet made up of calorie-rich, high-fat foods—including bacon, cake, and candy bars—not only became obese but were unable to stop eating even when threatened with an electric shock. Researchers think the obese rats' junk food diet overloaded their brains' reward systems and lowered levels of a receptor for the neurotransmitter dopamine—similar to the effect seen in drug addiction—causing them to compulsively eat. The findings are published in Nature Neuroscience.

    I don't see this trend changing any time soon either, but I wish our public high schools would treat PE/nutrition/healthy living classes like they do English and require it beyond one or two semesters. To some extent, we created a culture of cool to recycle, to go green...can we not make better attempts to do the same with exercise and eating habits?

    Too true evergreen! I'm in a 10,000 steps walking challenge now. My pedometer uploads to my laptop every day and I can see where I am in relation to others on my team. Let me tell you, that is motivation!

    Schools need to quit spending so much energy on chocolate milk and create the classes like you described!

    Too many processed foods are way too high in sodium & sugar, contain preservatives that are difficult to purge from the human body, are devoid of nutritional fiber and, lastly, calorie dense.

    How do scientists measure the calorie content of food?

    A: Physicists measure the energy content of food by burning the food. To a physicist, a calorie is the heat flow needed to raise the temperature of one gram of water by one degree Celsius. To measure the calorie content of food accurately, scientists use a "bomb calorimeter". The food sample to be measured is dried and ground into a powder (important point — all water content eliminated). Then it is placed into the bomb calorimeter, a strong metal container surrounded by a water bath. The metal container is pumped full of pure oxygen at 30 atmospheres pressure and the food is ignited. The resulting energy release is fast and violent, just like a bomb. The steel container holds in the explosion. Pure oxygen promotes combustion, and high-pressure oxygen greatly enhances combustion. All of the burnable parts of the dried and powdered food will burn in a calorimeter, leaving just a touch of ash. The calorimeter turns the energy stored in the food into heat flow. The temperature increase of the water and metal of the calorimeter reveals how many calories the food contained.

    Q: How many calories does a candy bar have???

    A: We saw in class that one food calorie (i.e., Calorie!) equals 1000 calories, which converts to 4200 joules. One joule of energy will lift a tenth of a kilogram one meter in the air. So one Calorie or 4200 joules will lift a 70 kilogram (155 pound) person six meters into the air. Calorimetry reveals that a Milky Way® candy bar contains more energy than a stick of dynamite. The candy bar contains 200 food Calories. That's 200,000 physicist calories or about 840,000 joules! Nearly a megajoule! A megajoule of energy from a candybar can perform enough work to lift an average 70-kilogram human being 1200 meters in the air. That's higher than the cliff face of Yosemite's El Capitan. No stick of dynamite can do that! In fact,an ounce of dynamite produces only one-quarter as many calories when it explodes as an ounce of sugar does when it burns.

    This is why I say, "No...not for the majority."

    People are playing with metabolic "dynamite"...and they will defend their diet to the grave.
