Better your burger
You know those little extras you love, like ketchup on burgers or hot sauce in tacos? Turns out they have hidden health benefits. Research shows that certain spices, herbs, and spreads not only boost flavor but can also help curb appetite, ease digestion, promote better memory, and even fight heart disease and cancer.
Here, 9 condiments to have on hand.
Ketchup
Benefit: Lowers risk of cardiovascular disease
Daily dose: 3-4 tablespoons
How it works: Lycopene—a powerful antioxidant in ketchup—may slow the process that leads to atherosclerosis, says Betty Ishida, PhD, a USDA research biologist. While all ketchup contains some lycopene, a study in the Journal of Agricultural and Food Chemistry found that organic versions contain up to 60% more per gram than conventional brands. The researchers also found that organic ketchup had the highest levels of vitamins A, C, and E.
Buckwheat Honey
Benefit: Fights aging
Daily dose: 2-4 tablespoons
How it works: Dark honey like buckwheat or blueberry contains the most antioxidants, say researchers at the University of Illinois Urbana-Champaign, who analyzed 19 varieties. Antioxidants protect cells from the damaging effects of free radicals and may reduce the risk of heart disease, cancer, cognitive decline, and macular degeneration.
Rosemary
Benefit: Eliminates foodborne carcinogens
Daily dose: 1-2 tablespoons
How it works: Rosemary minimizes or eliminates carcinogens formed when cooking some foods, say scientists at Kansas State University, who found that seasoning beef with rosemary before grilling can reduce cancer-causing substances called heterocyclic amines by 30 to 100%. Danish scientists got similar results when adding rosemary to dough. Acrylamide, a potentially carcinogenic compound, forms in carb-rich foods when heated above 250°F. "By incorporating 1 tablespoon of dried rosemary for each pound of f lour, we reduced acrylamide by more than 50%," says Leif Skibsted, PhD, a professor of food chemistry at the University of Copenhagen. He believes that the antioxidants in rosemary "scavenge" the harmful compounds.
Horseradish
Benefit: Detoxes your body
Daily dose: 1/4 teaspoon
How it works: Glucosinolates, compounds in the roots and leaves of the horseradish plant, can increase your liver's ability to detoxify carcinogens and may suppress the growth of existing tumors, says a study in the Journal of Agricultural and Food Chemistry. Horseradish is one of nature's best sources of glucosinolates—it has up to 10 times more than broccoli, the next-best source.
Olive oil
Benefit: Boosts long-term memory
Daily dose: A few tablespoons
How it works: Olive oil is a top source of oleic acid, an omega-9 fatty acid that is converted during digestion to oleoylethanolamide (OEA), a hormone that helps keep brain cells healthy. In a study from the University of California, Irvine, rodents fed OEA were better able to remember how to perform two tasks than those that didn't eat it. Researchers hypothesize that OEA signals the part of the brain responsible for turning short-term memories into long-term ones. "OEA seems to be part of the glue that makes memories stick," says Daniele Piomelli, PhD, a professor of pharmacology and biological chemistry at the university.
Cinnamon
Benefit: Stabilizes blood sugar levels
Daily dose: 1 teaspoon
How it works: People who added cinnamon—one-half to a heaping teaspoon—to a sweet dish experienced a slower rise in blood sugar than those who didn't consume any, finds a series of studies in the American Journal of Clinical Nutrition. The spice enhances insulin sensitivity, so it allows you to use more of the glucose in your blood, keeping blood sugar levels stable, says Joanna Hlebowicz, PhD, the studies' lead researcher and a fellow in cardiology at Lund University in Sweden. Adding cinnamon to a carb-heavy or starchy dish may also help stabilize blood sugar after you eat, she adds. Keeping levels stable minimizes sugar highs and lows, and for those with diabetes, it could mean needing less insulin.
Hot Sauce
Benefit: Curbs appetite
Daily dose: A few dashes
How it works: Eating just one meal that contains capsaicin—the compound that gives hot sauce and chile peppers their heat—not only reduces levels of hunger-causing ghrelin but also raises GLP-1, an appetite-suppressing hormone, says research in the European Journal of Nutrition. Other scientists found that people who drank capsaicin-spiced tomato juice before each meal over 2 days ingested 16% fewer calories than those who drank it plain.
Sauerkraut
Benefit: Eases digestion
Daily dose: 1/2 cup
How it works: Sauerkraut is full of probiotic bacteria such as Lactobacillus plantarum (L. plantarum) that can help relieve the gas, stomach distension, and discomfort associated with irritable bowl syndrome—and may improve the quality of life in up to 95% of those with IBS.
Black Pepper
Benefit: Guards against cancer
Daily dose: To taste
How it works: Piperine, a compound in black pepper, may help interrupt the self-renewing process of cancer-initiating stem cells, according to new research from the University of Michigan. "By limiting the number of stem cells, you're limiting the number of cells with the potential to form tumors," says lead study author Madhuri Kakarala, MD, PhD, a clinical lecturer in internal medicine at the University of Michigan Medical School.
