(NaturalNews) Phenolics. Flavonoids. Carotenoids. Quercetin. Phloridzin. What do these scientific names have in common? They are all types of phytonutrients, also called phytochemicals, found in fruits, vegetables, grains, legumes, nuts, and teas. And they may decrease the risk of not only minor illnesses like colds but also many of the major killers on the planet -- including cancer and heart disease. Scientists have only identified a few of the suspected vast number of these natural compounds in
foods that protect and build
health. But two facts are clear. First, most Americans don't get enough
phytonutrients in their daily diet for optimum health and, second, there's an easy strategy to boost your phytonutrient intake -- simply eat a mix of more naturally colorful foods.
The recently released
Phytonutrient Report, sponsored by the supplement company Nutrilite, used National Health and Nutrition Examination Surveys (NHANES) and USDA data to analyze what people in the U.S. typically eat each day. Because the same compounds that give plant foods various
colors are related to phytonutrient content, the report divided consumption into five categories of colors --
green, red, blue/purple, yellow/orange and white.
For example, the phytonutrients isothiocyanate, lutein and isoflavones are known to be abundant in green foods such as spinach and broccoli and lycopene and ellagic acid are found in red
fruits and vegetables like watermelon and tomatoes. White plant foods like onions and garlic are rich in allicin and
quercetin. Anthocyanidins and resveratrol are found in purple and blue foods like
grapes and blueberries while alpha-carotene, beta-carotene, hesperitin and beta-cryptoxanthin are most often in yellow/orange foods such as carrots and oranges.
The
Phytonutrient Report concludes there is a
phytonutrient gap in every
color classification. Specifically, 88% of Americans are eating too few foods in the blue/purple category, 79% are missing out on an adequate intake of yellow and
orange foods, and 78% don't have enough red veggies and
fruits in their diets. In addition, 69% lack enough daily green plant foods and 86% lack enough white plant foods.
"Many phytonutrients are powerful antioxidants that can help fight the damage caused to our bodies' cells over time that can lead to premature aging and
disease," Stephen Fortmann, M.D., director of the Stanford Prevention Research Center at Stanford University, said in a statement to the media. "The fact that Americans are falling short in phytonutrient rich fruits and
vegetables measured in the report is concerning."
Some estimates place the number of phytonutrients -- the vast amount still undiscovered and unstudied -- in the tens of thousands. So how can you up the odds you are getting all the available health enhancing, protecting and healing benefits of these remarkable
natural substances? Try consciously adding several colorful natural foods, with an emphasis on fruits and vegetables, to each meal.
Explore a variety of types of your favorite fruits and vegetables to get the maximum spectrum of phytonutrients, too. For example, drink green and white teas and eat both red and green grapes. Another case in point: a study by Cornell University
scientists published in the journal
Nutrition noted that the phytochemical composition of apples varies between different varieties of the
fruit.
