    亚裔料理网红琳达(Linda)在TikTok上表示,冰过再加热的隔餐白饭热量和碳水化合物会减少一半,不用因为怕变胖刻意吃比较少,还说这是「亚洲妈妈的秘密」;专业医师证实琳达说的没错,也分析背后的科学原理。

    @mamalindacooks 🍚👇🏼The secret is … 🍚👇🏼 🍚👇🏼 🍚👇🏼 … freezing your rice then reheat it! Research has shown that reheating frozen rice can reduce carb and calorie absorption by up to 50%. This is due to the formation of resistant starch, a type of carbohydrate that resists digestion in the small intestine and reaches the large intestine mostly intact. Unlike regular starch, which is quickly broken down into glucose and absorbed, resistant starch behaves more like dietary fiber. Resistant starch can promote gut health by acting as a prebiotic, feeding beneficial gut bacteria. It also helps regulate blood sugar levels, improves insulin sensitivity, and is helpful for weight management by increasing feelings of fullness. Resistant starch can be formed when certain starchy foods (e.g. rice) are cooked and then cooled or frozen. The cooling process changes the structure of the starch, making it more resistant to digestion. Incorporating resistant starch into your diet may have various health benefits, particularly for digestive health, blood sugar management, and weight control. Here’s how I freeze my rice: 1. Place about 1 cup of freshly cooked rice on a piece of plastic wrap. 2. Form rice into desirable shape. 3. Wrap tightly. Repeat. 4. Let cool slightly on countertop. 5. Freeze for 12 hours or till firm. 6. Place individually wrapped rice in a freezer bag. Keeps in freezer for up to 1 month. Here’s how I I reheat frozen rice: 1. Remove plastic wrap. 2. Place frozen rice in a microwave safe bowl. 3. Optional: Cover bowl with a wet paper towel. 4. Microwave on high for 1.5 to 2 minutes or till rice is thoroughly heated. 5. Gently fluff rice a few times. Enjoy! How does the rice taste? In my opinion, it tastes great. It’s moist and soft, not soggy or gummy. The texture stays the same as freshly cooked rice as well. 10/10 recommend! #rice #whiterice #mealprep #frozenfood #kitchenhacks #foodhacks #cookinghacks #healthycooking #resistantstarch #lifehacks

    纽约邮报(New York Post)报导,琳达在其TikTok帐号「@mamalindacooks」以影片分享白饭热量变低的秘密,影片获超过37万次浏览。

    医师兰加拉詹(Karan Rangarajan)在TikTok上表示,冰过再加热的隔餐白饭热量低不是迷思,是真的,他说冷藏、冷冻过再加热的饭、面包、意大利面、马铃薯、豆类和燕麦,热量都会变少。

    兰加拉詹解释,这现象是因为淀粉质淀粉质老化作用(Retrogradation),淀粉类食物冰过再加热后,「抗性淀粉」的含量会增加,这种淀粉不易被小肠酵素分解,进入大肠后会被肠内菌丛发酵成短链脂肪酸,其功能类似膳食纤维,也就是益生元(prebiotics),抗性淀粉可以促进肠道蠕动和排便,还能降低大肠癌的风险。

    兰加拉詹说,抗性淀粉的升糖指数低,让人在进食后血糖不会飙升,维持稳定,因为抗性淀粉在大肠发酵的速度较慢,会产生饱足感,让人不会吃太多,可以协助控制体重。

    兰加拉詹说,若想省去煮饭的麻烦,青香蕉是良好的抗性淀粉来源。

    不过,食用冰过的隔餐饭要特别注意,若过程处理不慎,可能引发「炒饭症候群」(Fried rice syndrome),指煮过的饭被俗称仙人掌菌的蜡样芽胞杆菌感染引发食物中毒,常见症状是上吐下泻,意大利面和马铃薯也可能导致这种状况。

    蜡样芽胞杆菌感染可能发生于煮过的饭放置室温过久、在冰箱放太久或没有适当加热。

    专家建议用高温煮饭,华氏40至140度是蜡样芽胞杆菌喜好生长的环境,饭煮好后不要在室温下放超过两小时,天气炎热时不要放超过一小时;煮好的饭应放入密封容器再放入冰箱,3至4天内若没有食用就要丢掉。
