Answering seems simple enough. For many people however, the need to avoid criticism and seek praise causes them to respond in a manner consistent with expected norms. Self-reports of dietary intake can be biased by these tendencies, tainting consumption data collected by the health community. Everyone knows they should eat five or more servings of fruits and vegetables a day, so that’s what they say when they’re asked — many even really believe it to be true.
The Upside of High Food Prices
June 26, 2008 | by
As the price at the gas pump continues to climb, so does the cost of diary, grain and meat products. Why? Because increasing fuel prices make it more expensive to grow, harvest, transport, process and package food. Indeed, food costs rose by 4 percent in 2007, the highest annual increase since 1990 [1]. In 2008, the U.S. Department of Agriculture predicts the consumer price index for all food will increase 4.5 to 5.5 percent as retailers continue to pass on fuel costs to consumers [1].
Overweight Kids and TV: An Advertising Epidemic
October 4, 2007 | by
On Saturday afternoon, September 29th, 2007, the cable television channel Nickelodeon showed nothing for three hours to celebrate “Worldwide Day of Play”, encouraging children to get off the couch and be active. The “Worldwide Day of Play” is part of Nickelodeon’s “Let’s Just Play” campaign, in partner with the Alliance for a Healthier Generation, to encourage kids to participate in active, healthy and playful lifestyles. The goal of the Alliance for a Healthier Generation is to create a new generation of healthy Americans by addressing one of the nation’s leading public health threats — childhood obesity.
So it should be simple, right? Don’t let kids spend so much time in front of the television … get them to be more active and they won’t be overweight. Or is there more to it? Let’s explore some of the science.
Quercetin
May 16, 2007 | by
Quercetin is a polyphenol, one of a number of water-soluble plant pigments called flavonoids (meaning class of plant secondary metabolites known for their antioxidant activity) that are largely responsible for the color of many flowers, fruits and vegetables. High concentrations of quercetin are found in apples, onions, tea and red wine [1]. Other sources of quercetin include olive oil, grapes, broccoli, cauliflower, cabbage, dark cherries and dark berries such as blueberries, blackberries and bilberries. The average U.S. citizen eating a normal, healthy diet including fruits and vegetables consumes approximately 25-50 mg of quercetin/day. Quercetin and other flavonoids (also referred to as bioflavonoids) cannot be produced in the human body.
Polyphenols
April 24, 2007 | by
Polyphenolic compounds (meaning the presence of more than one phenol group per molecule), often referred to as polyphenols, are plant-derived polyhydroxylated (meaning has more than one hydroxyl (OH), or alcohol, group attached) phytochemicals. Polyphenols are divided into three classes and include tannins, phenylpropanoids and flavonoids.
