With warmer weather looming on the horizon in Northern 
 America, many women and men start to simplify and streamline 
 their diets. Gone are the heavy chili dinners and beef stews 
 that fill our bellies in the dead of winter. Enter the 
 salad: cool, fresh, crisp bursts of flavor - but not 
 necessarily a significant caloric savings over a meat and 
 potatoes dinner. The culprit: creamy, oil based dressings. 
 The solution: for most, it's to take their dressing on the 
 side.
Traditional commerically prepared salad dressings are an 
 easy way to turn a healthy salad into a calorie-dense, 
 fat-laden disaster. Bottled dressings can have anywhere from 
 8 to 20 grams of fat per serving.
Take your dressing on the side? Never! At least, there's 
 never a need when you make your own healthy salad 
 dressings.
Of course, you can buy decent commercial low-fat dressings, 
 or even organic dressings but, more often than not, they are 
 loaded with unhealthy elements like sugar and heavy amounts 
 of heart-unhealthy sodium.
It's hard, however, to beat a homemade dressing!
The key to making delicious healthy dressings at home is to 
 reduce the oils and other fats, and bump up the ingredients 
 that add texture and flavor.
The oil in any salad dressing serves several functions, 
 including providing a "cling" or "binding" factor, so 
 your acidic and other flavorings (such as vinegar and herbs) 
 don't end up in a puddle at the bottom of the bowl.
Oil also serves to soften and balance the acids so that 
 they're more pleasing to the pallate.
When thinking of healthier dressings, most people eschew 
 creamy dressings in favor of lighter vinaigrettes. But 
 classic vinaigrettes often use a 3-to-1 or 4-to-1 ratio of 
 fat to acid (for example: olive oil and red wine vinegar). 
 Such a ratio can yield at least 10 grams of fat per 
 tablespoon! And who uses just one tablespoon?
So what constitutes a healthy salad dressing?
Let's look at oil.
When choosing oils for your dressing, think carefully about 
 flavors. Extra-virgin olive oil is almost always an 
 excellent healthful and flavorful choice. But so are nut 
 oils such as almond, macadamia and hazelnut. Each 
 contributes complex yet subtle flavors that can complement a 
 salad. Olive and nut oils also are rich in healthy 
 monounsaturated fats.
You can reduce the amount of oil, however, in any dressing 
 by approximately 40 percent if the other ingredients that 
 balance the dressing are not too acidic.
A common complaint when reducing the oil content of a 
 dressing recipe is that one often misses the thick texture 
 that oil adds to your recipes. Try adding Dijon mustard as 
 an emulsifier to make up for the reduced oil. Like oil, 
 mustard is thick enough to bind the other ingredients and 
 adds a tangy flavor.
In creamy dressings, the emulsifier often is sour cream or 
 mayonnaise (and sometimes oil, too). Providing a healthy 
 option for these ingredients is an easy fix.
Nonfat yogurt, reduced-fat sour cream, and reduced-fat 
 mayonnaise all make good substitutes. They each have good 
 flavor and produce dressings that hold together and coat 
 vegetables quite well.
Or try buttermilk. Buttermilk is always either nonfat or 
 reduced-fat. Its thick texture and mild, tangy flavor makes 
 it a useful ingredient.
With a little bit of ingenuity and creativity, it is 
 possible to make healthy salad dressings without sacrificing 
 good nutrition by cutting calories, fat and chemicals.
