Curry Dilates Arteries With One Serving
Did you know that a single culinary serving of spices in the form of curry can dilate your arteries, preventing the cardiovascular harms associated with eating common foods?
While spices are thought of mainly as culinary agents for the aesthetical enhancement of the flavor of food, they are also powerful medicinal agents, and in certain respects may actually mitigate the harms of things we like to eat that may not be as good for us as their pleasurable tastes and textures would have us believe.
A recent study published in Nutrition Journal titled, “A single consumption of curry improved postprandial endothelial function in healthy male subjects: a randomized, controlled crossover trial,” brought home exactly this point. Moreover, it reveals that certain culinary formulas, sometimes handed down through countless generations, may have indispensable value for our health. Interestingly, we find this concept echoed in the word recipe itself, whose first recorded use in Mid 16-century French literally means “medical prescription.”
A curry is essentially a blend of various spices used as a sauce in dishes, and in the case of this study’s tested formula, a traditional Japanese combination was used containing the following 8 herbs: Clove, coriander, cumin, garlic, ginger, onion, red pepper, turmeric. [Note: click the hyperlinks of the preceding 8 herbs to view the extensive database of healing properties we have amassed on each one] Interesting, Japanese curry was actually introduced to Japan by the British during the Meiji period (1868–1912) when India was still under colonial rule, making it a “Western” influence there, even though it ultimately originated in the Indian subcontinent and Southeast Asia.
In the study, researchers tested 14 healthy male subjects with an average age of 45 years, who were given either a single serving of curry meal or spice-free control meal (180 g of curry or control and 200 g of cooked rice; approximately 500 kcal in total). Researchers then tested what happened to the blood vessels of subjects before and consuming either meal.
A variety of Indian curries.
Based on post-meal measurements of the ability of blood to pass through the blood vessels (postprandial flow-mediated vasodilation (FMD)) and other parameters, clearly the consumption of curry increased the blood flow through the blood vessels (increased FMD), whereas the consumption of the curry-free control meal resulted in a decrease in blood flow (decreased FMD). More specifically, the results were reported as follows:
The consumption of the control meal decreased FMD from 5.8 ± 2.4% to 5.1 ± 2.3% (P = 0.039). On the other hand, the consumption of the curry meal increased FMD from 5.2 ± 2.5% to 6.6 ± 2.0% (P = 0.001), and the postprandial FMD after the curry meal was higher than that after the control meal (P = 0.002). Presence of spices in the curry did not alter significantly the systemic and forearm hemodynamics, or any biochemical parameters including oxidative stress markers measured.”
The researchers concluded that curry prevented the negative effects of the meal upon post-meal “endothelial function,” that is, it prevented the inner lining (endothelium) of the blood vessels from contracting and inhibiting the normal flow of blood throughout the cardiovascular system. They surmised that the antioxidant activity of the spices likely are responsible for the observed positive outcomes, possibly through blunting the post-meal increases in blood sugar and/or oxidative stress. They summarized their findings:
