近日，國際著名雜志Nutrition and Diabetes刊登了丹麥研究人員最新的研究成果,，研究人員研發(fā)出一種新型巧克力，含有亞麻籽等多種具減肥功效的成分,，希望能讓消費者在享用美味的同時又不用擔心發(fā)胖,。
哥本哈根大學研究人員說，他們在這種新型巧克力中加入了亞麻籽,，因為亞麻籽中含有歐米加3等多元不飽和脂肪酸,，使亞麻籽中的食用纖維可以和人體腸道中的脂肪結合后排出體外，從而減少人體對脂肪的吸收,，達到減肥效果,。此外，這種巧克力配料中還有辣椒等特殊成分,，有助于加速人體的血液循環(huán)和新陳代謝,。
領導研究的哥本哈根大學營養(yǎng)學系教授阿爾內·奧斯楚普說，該研究小組下一步計劃對這種新型巧克力的減肥作用進行驗證,，準備讓不同測試人群分別食用普通巧克力和新型巧克力,，然后對比24小時內不同測試對象的熱量消耗數(shù)據(jù)，檢驗新型巧克力的減肥功能,。（生物谷Bioon.com）

Eating dark and milk chocolate: a randomized crossover study of effects on appetite and energy intake
L B Sørensen1 and A Astrup1
Objective: To compare the effect of dark and milk chocolate on appetite sensations and energy intake at an ad libitum test meal in healthy, normal-weight men. Subjects/methods: A total of 16 young, healthy, normal-weight men participated in a randomized, crossover study. Test meals were 100 g of either milk (2285 kJ) or dark chocolate (2502 kJ). Visual-analogue scales were used to record appetite sensations before and after the test meal was consumed and subsequently every 30 min for 5 h. An ad libitum meal was served 2 h after the test meal had been consumed. Results: The participants felt more satiated, less hungry, and had lower ratings of prospective food consumption after consumption of the dark chocolate than after the milk chocolate. Ratings of the desire to eat something sweet, fatty or savoury were all lower after consumption of the dark chocolate. Energy intake at the ad libitum meal was 17% lower after consumption of the dark chocolate than after the milk chocolate (P=0.002). If the energy provided by the chocolate is included in the calculation, the energy intake after consumption of the dark chocolate was still 8% lower than after the milk chocolate (P=0.01). The dark chocolate load resulted in an overall energy difference of −584 kJ (95% confidence interval (−1027;−141)) during the test period. Conclusion: In the present study, dark chocolate promotes satiety, lowers the desire to eat something sweet, and suppresses energy intake compared with milk chocolate.
