The demands of our careers and family seem to have lead to the demise of the healthy diet. Now, with no time for cooking and preparing healthy meals, we head for what's convenient -- and more times than not, this is unhealthy, leading to obesity, diabetes and heart disease, among other things.

But what if healthy meals were convenient? Some are -- and they can be found in the frozen foods section of your supermarket. Yes, some frozen entrees are healthy, according to this article from WebMD -- namely the ones with lean protein, veggies and whole grains. And if you're relying on McDonald's to feed your family, they can make a world of difference to your health -- studies show that obese adults who ate prepared meals rather than home-cooked ones were more likely to lose significant amounts of weight.

So how do you know if your frozen meal is healthy? Read the labels. Look for meals that are low in calories, low in fat and -- this one's a biggie -- low in sodium.

What's your favourite frozen meal?
