营养食品（应该是指商场里的营养品、保健品、有减肥功效的营养品等）区：一个危险的地方
可口可乐、百事、保健药品、无脂肪食物，营养蔬菜……在我们所看到和听到的每个地方，我们都被“营养品”这个词所包围。我们很容易就会被营养品的可能性（比如其某方面的特效）所吸引，以至于忘了去思考什么它对我们起什么作用。我们正为购买那些对我们的精神或身体有害的产品。
营养品很可观地从精神上弱化着我们。从一种层面上说，我们不愿意承认我们的体重问题事实上并不在于减少体重上，而是在对脂肪、高热量、不健康食物的消耗量的支配上。营养品让我们跳出思考阶段而直奔秤。我们所要做的就是咽下还是去认识贴着食品标签的“营养品”（我们应该毫不犹豫地吃下去还是先认识一下它对我们的影响）。
从另一种层面上说，营养品在精神上有较大的影响。每次我们喝了不含热量的饮料，我们就会在不知不觉中告诉自己我们不需要去努力弄出结果来（它对我们是否有害）。营养品让人们相信一点，那就是无需疼痛就可以获得（不需要付出，就可以收获），而且生活是可以不需要抵抗和奋斗的。
营养品的危害不仅仅在于它给我们带来的精神上的影响中，还存在于它所导致的身体上的危害。营养品间接的对我们的身体造成了伤害，因为在消耗它们而非健康食品的过程中，我们也在阻止身体吸收基础的营养成分。营养品和保健药品中不含热量，那只是因为食品加工业通过制造化学成分来生产出这些特效产品。营养品不可能含营养价值，而其中所添加的化学成分可能很危险。
既然我们注意到了营养品给我们带来的影响，那就是时候慎重考虑要不要去买它们。减肥来自于意志力，而非化学物质的作用。一旦我们认识到这一点，我们就更能去抵制营养品，因而去阻止在使用过程中它们所带来的精神危害。

Diet Coke, diet Pepsi, diet pills, no-fat diet, vegetable diet… We are surrounded by the word "diet" everywhere we look and listen. We have so easily been attracted by the promise and potential of diet products that we have stopped thinking about what diet products are doing to us. We are paying for products that harm us psychologically and physically.
Diet products significantly weaken us psychologically. On one level, we are not allowing our brain to admit that our weight problems lie not in actually losing the weight, but in controlling the consumption of fatty, high-calorie, unhealthy foods. Diet products allow us to jump over the thinking stage and go straight for the scale instead. All we have to do is to swallow or recognize the word "diet" in food labels.
On another level, diet products have greater psychological effects. Every time we have a zero-calorie drink, we are telling ourselves without our awareness that we don't have to work to get results. Diet products make people believe that gain comes without pain, and that life can be without resistance and struggle.
The danger of diet products lies not only in the psychological effects they have on us, but also in the physical harm that they cause. Diet foods can indirectly harm our bodies because consuming them instead of healthy foods means we are preventing our bodies from having basic nutrients. Diet foods and diet pills contain zero calorie only because the diet industry has created chemicals to produce these wonder products. Diet products may not be nutritional, and the chemical that go into diet products are potentially dangerous.
Now that we are aware of the effects that diet products have on us, it is time to seriously think about buying them. Losing weight lies in the power of minds, not in the power of chemicals. Once we realize this, we will be much better able to resist diet products, and therefore prevent the psychological harm that comes from using them.
