What Are MUFAs? | Ask the Fitness Nerd

What’s a MUFA? The Fitness Nerd explains what this funny acronym means and why MUFAs are suddenly the rage among dieters.

Dear Fitness Nerd:

What are MUFAs? I keep hearing people talk about them, but I still haven’t quite figured out what they are. I know they are a type of fat, but I thought fats were unhealthy and should be avoided. Are they a supplement of some type like CLA? - Kayla R, (West Hollywood, CA)

MUFAs are an acronym for a “monounsaturated fatty acids” — a class of healthy fats found in foods like nuts and seeds, avocados, olives and certain vegetable oils. MUFAs are not typically taken as a supplement (as Conjugated linoleic acid or CLA often is), since they are plentiful in foods. 

MUFAs have gotten a lot of attention recently for three reasons:

1. MUFAs may help you lose weight.

There is some evidence that people who regularly consume MUFAs have lower body fat levels and are more successful at dropping body fat and weight than people who are on low-fat, carbohydrate rich diets.

This research flies in the face of  the conventional-wisdom that drove the low-fat craze of the 80s and 90s, which advised people to reduce their fat consumption as much as possible in order to lose weight, lower cholesterol and reduce the risk of stroke, high-blood pressure and heart disease. The latest research actually suggests that diets which are higher in healthy fats like MUFAs may be more effective at weight-control than low-fat diets.

2. MUFAs may reduce the risk of disease.

A growing body of research shows that MUFAs may not only help people lose fat, but that they also have protective properties that may lower the risk of developing certain diseases, including Type II Diabetes, heart disease, stroke and possibly certain types of cancers. MUFAs are also part of The Portfolio Diet, which is an approach to eating that combines MUFAs with other cholesterol-lowering foods like soy, plant sterols and soluble fiber from things like oatmeal and may reduce blood cholesterol-levels as effectively as prescription statin drugs.

Skim Milk | Healthy Food of the Day

Learn how adding skim milk to your diet can help you build muscle, strengthen bones and maybe even lose some body fat along the way.

“Milk - it does a body good” has a new meaning for people looking to add muscle, stave-off bone loss and reduce body fat.

A flurry of research — albeit, mostly funded by the dairy industry — over the past few years has suggested that including skim milk or fat-free milk into your diet can actually help you lose weight. But aside from the weight loss claims (which we’ll take a look at later), there are additional reasons that including skim milk in your diet can keep you fit, trim and healthy.

What is Skim Milk?

Skim milk is whole milk from dairy cows that has most or all of it’s fat removed. 

Traditionally, this was done by letting milk settle, and then “skimming” the fat off the top of the milk. What is left is the protein-rich, low-fat liquid below the layer of fat. In modern milk processing, the de-fatting process is done with centrifuges (basically the milk is spun around inside a big stainless steel tank and the fat is separated and drained off.)

Skim milk (also labeled as “fat-free milk” or “non-fat” milk) generally has less than 0.5 percent milk fat. Low-fat, semi-skimmed milk or “1% milk” has between 1 and 2 percent fat. For comparisons sake, whole cows milk has around 3.5 percent fat, or 7.9 grams of fat (4.6 grams of which are the “bad” saturated type of fat) in a 1 cup (16 oz) serving. In terms of calories, whole milk weighs in at 147 calories, in comparison to the 91 calories in skim milk.

Clearly choosing skim milk over whole or even 2% milk makes the most sense from a fat and calorie perspective.

But what about the difference in nutrition between skim milk and whole milk? Does the skimming process remove any nutrients?
