Food Myths Debunked(v.揭穿)

1.Fat Free - Lose Weight

The Myth: Fat free food is calorie free

This is a very common myth - so common that food manufacturers market to it. The misconception(n.误解)that fat free is better is the reason that so many products are labelled “fat free,” “low in fat,” “fat reduced,” etc. So many people who want to lose weight will chow down(吃)on all of these “low fat” foods thinking they are going to lose weight - even worse, they often tend to eat more of the low fat food than they would have if it were full fat. What really matters when trying to reduce weight is calories - eat fewer calories than you burn and you will lose weight.

2. Eat The Salad

The Myth: Fast food salads are the “healthy option”

A 2005 report by the Independent said: “[an investigation of the food sold by the “big four” - McDonald’s, Burger King, KFC and Pizza Hut - found that […] five out of eight of the salads used as “evidence” of their embrace of healthy eating had “high” salt or fat content.”It is all too common to see dieters(减肥者) who crave a little something naughty(adj.不适当的), ordering salads or other “healthy choices” from fast food joints - but what they usually don’t realize is that the salads can be as bad as the regular food and they would be more content if they just ate a Big Mac.

3.Salt Increases Blood Pressure

The Myth: Excess(adj.过度的,过量的) salt increases your blood pressure

Science has since found out that there is no reason for a person with normal blood pressure to restrict their salt intake. However, if you already have high blood pressure, you may become salt-sensitive in which case you should reduce salt or increase your potassium(钾) intake as it is the balance of the two that really matters. Furthermore, people who suffer from hypertension(高血压)should be careful with salt as it can have an impact there. Ultimately, eating more potassium is probably more important than reducing salt. Potassium rich foods are spinach, broccoli, bananas, white potatoes and most types of beans.

脱脂—减肥

脱脂食物不含卡路里。

这种想法很普遍,食品生厂商并以此为商机。正因为大家都错误的认为脱脂食品更好,于是很多商品都标有“脱脂”“低脂”“降脂”等等。很多想减肥的人爱吃这类低脂食品。糟糕的是,他们吃得很多,如果是全脂的,他们也就不会吃这么多了。然而真正与体重有关的是卡路里,吃得少燃烧得多,这样你才能减肥。

吃沙拉

快餐沙拉是健康的选择

《独立报》2005年曾报道:“对四大巨头(麦当劳,汉堡王,肯德基和必胜客)进行调查发现,用来证明其他们的食品很健康的沙拉,其中5/8富含盐或脂肪。”常常看到很多人追求一些不适的东西,在吃快餐时点沙拉或是做其它健康的选择,但他们很少意识到沙拉和常规食品一样的糟糕,而且如果他们仅仅只吃麦当劳,盐和脂肪的含量会更高。

盐会使血压升高

食用过量的盐会使你的血压升高。

科学研究发现,血压正常的人根本没必要限制食盐量。然而,如果你已经患上高血压,你就会对含盐食品敏感,要么减少食盐量,要么增加食钾量,因为与之真正相关是盐和钾的平衡。高血压患者之所以要谨慎食盐,原因也就在此。可见,多食钾比少食盐更为重要。富含钾的食物有菠菜、花椰菜、香蕉、土豆和大多数豆类。
