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.
