I can’t say I am really surprised by the news that Salads ‘rival Big Macs for fat’, prepared ready to eat meals are never as healthy, or tasty for that matter, as homemade meals IMHO.
It is quite shocking, to me anyway, that people buy prepared salads. Salads are so easy and quick to make and they certainly do not need to be packed with calories and fat. Yes, you can make an indulgent salad but you can also make a healthy, low calorie, delicious salad in no time at all, and at a fraction of the cost.
“It is a good idea to try making salads yourself because this is the best way of knowing exactly what is in them.”
I couldn’t agree more with Nathalie Winn if I tried! 
What I am really surprised about is that there are sooo many calories in one of McD’s cardboard big mac burgers, WOW who knew that about cardboard 
Fast food salads also have lots of sugar, too. Sugar+fat= more sales: http://cli.gs/vuBNhv
I like salads made from garden-grown vegetables and greenery: absolutely delicious, much better than stuff from the shops or even local farmers (who still produce in huge scales on the same soil every year).
