Unit 2 Healthy eatingFor Healthy Eating, Bitter Is Better1. Eat More Bitter Foods. Were all born with an aversion to bitterness, but our levels of sensitivity vary greatly. Some kids will eat broccoli from the get-go. It may taste one-third as bitter to them as it does to the child who tests your very last nerve at the dinner table. You can usually tell who is the tolerant taster (that is, the one with the less sensitive palate) and who is the hyper taster (I only eat white foods), but you can coach and nurture them both into being open-minded eaters.2. Try Something New. At a restaurant, order something you would never cook at home. Instead of recoiling at the smell of something foreign and pungent, get to know it better. I used to abhor the very smell of canned tuna. That was before I landed a canned-tuna client and had to taste it every week for four years. These days Im an aficionado of good (healthy) tuna.3. Do a Hated Horizontal. Pick a food that you hate but know you should eat more often, and teach yourself a bit about it. By sampling across a whole category of foodbeans, for instance, if they are your most hated foodyou are more likely to notice and appreciate the differences in textures, colors, flavors, tastes. Wine tasters call this a horizontal tasting. Find your least-hated bean and eat them once a day for a week. At the end of the week, if you still hate them, youre free to take a pass.健康饮食还需多吃“苦”1. 多吃苦味食物。我们大家生来都不喜欢苦味，但是我们的敏感度存在巨大差异。有些儿童一开始就愿意吃西兰花，他们所感觉到的西兰花的苦味可能相当于在饭桌上让你忍无可忍的孩子所感觉到的苦味的三分之一。我们通常都能分辨出谁是不挑食的人（也就是味蕾不那么敏感的人）、谁是极端挑食者（比如“我只吃白色食品”的人），不仅如此，我们还能对这两种人进行训练，把他们都培养为毫不挑食的人。2. 尝试一些没吃过的食物。在餐馆吃饭时，点一些你平常绝不会在家做的食物。不要一闻到一些奇特的和刺鼻的味道就打退堂鼓，要更好地去了解它。以前有一段时间我非常厌恶金枪鱼罐头的那股气味，但那是在我找到一位生产金枪鱼罐头的客户、从而不得不每周都要品尝它长达四年时间之前的事儿了。现如今我已经迷上了优质的（健康的）金枪鱼。3. 对讨厌的食物来一场“水平品鉴”。选择一种你讨厌但你知道应该常常多吃的食物，然后对这种食物做些了解。遍尝一整类食物之后（比如说豆类，如果它们是你最讨厌的食物的话），你更有可能会注意和品鉴到它们在口感、颜色、风味和味道上的差别。红酒品鉴师把这种品鉴方式称为“水平品鉴”。通过这种方法找到自己最不讨厌的那种豆子，然后连续一星期每天都吃一次。如果在这个星期结束
