US obesity and diabetes rates are among the globe's very highest. Why? On her blog, the NYU nutritionist and food-politics expert Marion Nestle recently pointed (hat-tip, RealFood.org) to this telling chart on how we spend our grocery money, from the USDA's Amber Waves
So, we do a pretty good job eating enough potatoes. But the healthier, more brightly colored vegetables like kale and carrots, no so much. We spend four times the amount on refined grains the USDA thinks is proper, and about a fifth of the target expenditure in whole grains. We spend nearly 14 percent of our at-home food budgets on sugar and candies, and another 8 percent on premade frozen and fridge entrees. Whole fruit barley accounts for less than 5 percent of our grocery bill. And so on—a pretty dismal picture.
That chart deals with at-home expenditures. What about our food choices out in the world? The USDA article has more. This chart shows that we're getting more and more of our sustenance outside of our own kitchens.
And while the article doesn't offer comparable data to the above at-home chart about expenditures outside the home, it does deliver evidence that our eating out habits are pretty dire as well.
