Recipes often suggest leaving the broth to simmer for hours.
肉汤通常需要数小时的小火慢炖.
'Complex chemical reactions take place — and the more disintegrated the bones, (and, therefore, digestible) the massive protein molecules, which are the cement of the body, become,' explains Dr Christie.
克里斯蒂博士解释说："其中发生了许多复杂的化学反应——骨头分解的越彻底,大的蛋白分子就变得越易消化.而这些蛋白分子是人身体的基石."
Minerals and nutrients such as calcium, magnesium and cartilage also become easy to digest. The broth is thought to have benefits for bones, teeth and joints and help hair and fingernails to grow.
矿物质以及钙、镁和软骨等营养物质也变得容易消化.肉汤据信对骨骼、牙齿和关节很好,而且能促进头发和指甲的生长.
'Only re-heatany food once and ensure it's very hot (over 60 degrees celsius) to kill any bacteria,' says Dr Goldberg.
哥德堡博士说："任何食物只能重复加热一次,而且要保证高温（60摄氏度以上）灭菌."
VEG TO BEAT IBS
蔬菜防止肠易激综合征
We all know that cooking vegetables for longer removes vitamin C. But some believe that people with digestive problems, such as irritable bowel syndrome, ought to overcook vegetables containing insoluble fibre, such as onions and garlic, which can cause bloating. Reheating the next day could supposedly soften them further.
大家都知道,为了不破坏维生素C,烹饪蔬菜时不可煮太久.但一些人认为有消化问题的人,如患有肠易激综合征的人,应该将洋葱、大蒜等含不溶性纤维（容易引起腹胀）的蔬菜多煮一段时间.而隔夜菜再加热时正好可以进一步软化这些纤维.
Dr Christie is unconvinced. 'Sorry, you aren't going to make any real difference to the molecular structure,' she says.
克里斯蒂博士对此表示不认同,她说："对不起,你不会对其分子结构做出任何实质性的改变."
'This isn't proven and I don't recommend it. IBS suffers ought instead to find out which foods to avoid on specialist websites, such as ibsdiet.org.'
"这种说法尚未被证实,我不推荐.但那些患有肠易激综合征的患者应该关注专业网站,如ibsdiet.org,以避免食用某些食物."
'GOOD GUT' POTATOES
土豆有助肠道健康
A 1992 UK study found cooked potatoes contained just 7 percent resistant starch (the indigestible type). But when cooled, it jumped to 13 percent.
英国1992年的一项研究发现,煮熟的土豆只含7%的抗酶解淀粉（不易于消化型）,但当冷却后这一数字却骤升至13%.
