What’s the single best food to keep on hand in your healthy kitchen? It just might be blackberries, which will be coming into season soon in much of the country. Research published in the July, 2006, issue of the American Journal of Clinical Nutrition ranked blackberries as far and away the most antioxidant-rich food (on the basis of a typical single serving) out of 1,113 types tested. Next in line were walnuts - which had about 40 percent fewer antioxidants than blackberries - followed by strawberries, artichokes, cranberries, coffee, raspberries, pecans, blueberries and ground cloves.
Antioxidant concentration is not the only nutrition criterion that matters, of course. A healthy diet must also balance macronutrients (protein, carbohydrates and fats) and provide enough fiber, trace minerals, proper hydration and so on. But you can’t go far wrong by eating blackberries on a regular basis.

Green Tea and Lung Cancer
Green tea isn’t a cure for cancer, but new research suggests that it might be a promising ingredient in developing drugs to treat lung cancer. Researchers at the Center for Human Nutrition at the University of California at Los Angeles (UCLA) recently studied human lung cancer cells marinated in a decaffeinated green tea extract for up to three days. The result they noted in the lab was a remodeling of a protein that makes the cells more likely to stick together, a finding that indicates something in the extract could be beneficial in humans, and might lead to new lung cancer drugs. The investigators aren’t certain whether credit goes to a single antioxidant in the extract or to a combination of antioxidants. While they’re a long way from concluding that drinking green tea benefits lung cancer patients, they suggested that drugs targeting the protein remodeled by the extract they used in the lab could be helpful. The findings were published in the March 12, 2007, online edition of

If You Work in an Office …
…and spend long hours at your desk on the computer, make sure you get up and walk around once in a while. New Zealand researchers have found that office workers have a higher than normal risks of developing deep vein thrombosis (DVT), potentially fatal blood clots that can travel to the heart, lungs or brain. Symptoms include breathlessness and chest pain, perhaps even leading to heart attack. A stroke is another serious risk. Until now, DVT had been referred to as “economy class syndrome” because risks were considered greatest among airplane passengers sitting in coach with little room to stretch their legs. But when the New Zealand investigators checked a sample of 62 people admitted to hospitals with blood clots they found that 34 percent were office workers, some of whom sat at their computer screens for 14 hours a day and went three or four hours without getting up. Predictably, 21 percent of the study group reported recent long-distance flights. The study was carried out by the Medical Research Institute in New Zealand.

Eggplant-Walnut Pâté
Traditional pâtés are often made from high-fat meats and liver. They can be delicious and quite elegant, but less than nutritious. This vegetarian version is sophisticated, filled with flavor, and healthful. Enjoy it on a special occasion or as an everyday spread with whole-grain crackers.
