The answer above, while a popular belief, is not entirely true. Just because a dog is a mix of two (or more) breeds, does not mean that any genetic faults or health problems that come with one breed are cancelled out with another. In fact, the resulting offspring can inherit both of the parent's genetic issues, such as hip dysplasia and elbow dysplasia, just to name a few of the more common health issues.
A purebred dog which belongs to a good, reputable breeder has a much higher chance of producing healthier offspring. The reason for this is that good breeders spend many hundreds of pounds/dollars on health tests, which test the potential breeding dog's elbows, hips, eyes, and whatever else that may be a health issue in the particular breed. A good breeder will only breed a dog if it has good scores (amongst other things). This ensures the risk of passing on genetic problems to the offspring is kept at a absolute minimum.
Unfortunately, many breeders (purebred and of crossbred) do not health test their dogs, so the resulting offspring could end up with a myriad of problems brought on by bad breeding practices.
Overall health, such as being able to eat food scraps, is not determined by breed, but more of the individual dog itself. Many dogs have strong stomachs and able to eat many things, but other dogs will naturally have more sensitive stomachs.
So no, a mixed breed dog does not necessarily mean its healthier, or that purebred dogs are sickly or inbred.
