Adding an array of spices to meals is a surefire way to make it tastier, but new Penn State research suggests it may increase its health benefits as well.In a randomised, controlled feeding study, the researchers found that when participants ate a meal high in fat and carbohydrates with six grams of a spice blend added, the participants had lower inflammation markers as compared to when they ate a meal with less or no spices."If spices are palatable to you, they might be a way to make a high-fat or high-carb meal more healthful," said Connie Rogers, associate professor of nutritional sciences."We can't say from this study if it was one spice in particular, but this specific blend seemed to be beneficial," added Rogers.The researchers used a blend of basil, bay leaf, black pepper, cinnamon, coriander, cumin, ginger, oregano, parsley, red pepper, rosemary, thyme and turmeric for the study, which was recently published in the Journal of Nutrition.According to Rogers, previous research has linked a variety of different spices, like ginger and tumeric with anti-inflammatory properties.Additionally, chronic inflammation has previously been associated with poor health outcomes like cancer, cardiovascular disease, and overweight and obesity, which affects approximately 72 per cent of the US population.In more recent years, researchers have found that inflammation can spike after a person eats a meal high in fat or sugar.While it is not clear whether these short bursts -- called acute inflammation -- can cause chronic inflammation, Rogers said it's suspected they play a factor, especially in people with overweight or obesity."Ultimately the gold standard would be to get people eating more healthfully and to lose weight and exercise, but those behavioural changes are difficult and take time," Rogers said."So in the interim, we wanted to explore whether a combination of spices that people are already familiar with and could fit in a single meal could have a positive effect," Rogers added.For the study, the researchers recruited 12 men between the ages of 40 and 65, with overweight or obesity, and at least one risk factor for cardiovascular disease. Rogers said the sample was chosen because people in these demographics tend to be at a higher risk for developing poorer health outcomes.In random order, each participant ate three versions of a meal high in saturated fat and carbohydrates on three separate days: one with no spices, one with two grams of the spice blend, and one with six grams of the spice blend. The researchers drew blood samples before and then after each meal hourly for four hours to measure inflammatory markers."Additionally, we cultured the white blood cells and stimulated them to get the cells to respond to an inflammatory stimulus, similar to what would happen while your body is fighting an infection," Rogers said."We think that's important because it's representative of what would happen in the body. Cells would encounter a pathogen and produce inflammatory cytokines," Rogers added.After analysing the data, the researchers found that inflammatory cytokines were reduced following the meal containing six grams of spices compared to the meal containing two grams of spices or no spices.Rogers said six grams roughly translates to between one teaspoon to one tablespoon, depending on how the spices are dehydrated.While the researchers can't be sure which spice or spices are contributing to the effect or the precise mechsm in which the effect is created, Rogers said the results suggest that the spices have anti-inflammatory properties that help offset inflammation caused by the high-carb and high-fat meal.Additionally, Rogers said that a second study using the same subjects, conducted by Penn State researchers Penny Kris-Etherton and Kristina Petersen, found that six grams of spices resulted in a smaller post-meal reduction of "flow-mediated dilation" in the blood vessels -- a measure of blood vessel flexibility and marker of blood vessel health.In the future, Rogers said she, Kris-Etherton, and Petersen will be working on further studies to determine the effects of spices in the diet across longer periods of time and within a more diverse population.( With inputs from ANI )
