研究顯示：甜椒堿可控制體重

食品伙伴網(wǎng)報(bào)道，據(jù)美國(guó)營(yíng)養(yǎng)成分網(wǎng)8月19日消息，一項(xiàng)來(lái)自加拿大的最近研究表明。甜椒中的一種無(wú)辣味的化合物---甜椒堿，可通過(guò)促進(jìn)脂肪作為能源消耗而起到控制體重作用。
 

來(lái)自加拿大麥克馬斯特大學(xué)運(yùn)動(dòng)新陳代謝研究小組的研究者發(fā)現(xiàn)，每天攝入10毫克劑量的被純化的甜椒堿，會(huì)增加20%的能量消耗。
研究者們招募了12名平均年齡為24.3、BMI也正常的的健康男性參與了研究，受試者被隨機(jī)分為兩組，接受服用甜椒堿或安慰劑。在進(jìn)行了90分鐘適度的劇烈運(yùn)動(dòng)后休息時(shí)對(duì)他們進(jìn)行了代謝和產(chǎn)熱效果的分析測(cè)試。結(jié)果顯示，服用甜椒堿的一組與服用安慰劑的一組相比，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.
