食品伙伴网报道，据美国营养成分网8月19日消息，一项来自加拿大的最近研究表明。甜椒中的一种无辣味的化合物---甜椒碱，可通过促进脂肪作为能源消耗而起到控制体重作用。
来自加拿大麦克马斯特大学运动新陈代谢研究小组的研究者发现，每天摄入10毫克剂量的被纯化的甜椒碱，会增加20%的能量消耗。
研究者们招募了12名平均年龄为24.3、BMI也正常的的健康男性参与了研究，受试者被随机分为两组，接受服用甜椒碱或安慰剂。在进行了90分钟适度的剧烈运动后休息时对他们进行了代谢和产热效果的分析测试。结果显示，服用甜椒碱的一组与服用安慰剂的一组相比，能量消耗增加了20%。

Sweet pepper compounds show weight management power
Post a commentBy Stephen Daniells, 19-Aug-2010
Capsinoids, non-pungent compounds in sweet pepper, may boost energy use by promoting the use of fat as the energy source, suggests a new study from Canada.
A daily 10 milligram dose of purified capsinoids increased energy use by 20 percent, according to findings from scientists from the Exercise Metabolism Research Group at McMaster University.
“This study was the first to assess the effect of capsinoids and aerobic exercise together in humans on measures of substrate oxidation and energy expenditure,” wrote the researchers, led by Stuart Phillips.
None of the apparent beneficial effects on energy use were carried over to the exercising state, although this may be due to the exercise regime being too intense, said the researchers.
“Further studies are needed to assess this, possibly implementing an exercise regimen that more closely mimics daily routines of the general North American population, i.e. activity that is less strenuous and shorter,” they stated.
The study supports the potential weight management actions of capsinoids, sisters compounds to the more famous and more pungent compound capsaicin.
The new study was supported by Ajinomoto Inc. The FDA issued a GRAS letter of no objection to Ajinimoto in early 2009 for the company's capsinoid ingredient .
Study details
Phillips and his co-workers recruited 12 healthy young men with an average age of 24.3 and average BMI to participate in their study. Subjects were randomly assigned to receive either a placebo or the purified capsinoids.
The metabolic and thermogenic effects were analysed at rest and after 90 minutes of moderately intense exercise.
“In this crossover, double-blind, acute trial, compared to a placebo, capsinoids increased resting energy expenditure by about 20 percent, and based on several observations relating to lipid metabolism […], capsinoid ingestion induced greater lipid oxidation at rest,” said the researchers.
“Although none of these effects carried over into exercise, the blunted lactate response with capsinoids 30 min into the exercise bout suggests an altered substrate use, namely a greater reliance on fat as fuel, at the start of exercise.
“This study […] further proves that the subtle metabolic effects of capsinoids are most pronounced at rest and as demonstrated in this trial, they seem to be superseded by a moderate exercise regimen,” they concluded.
