Do you think Vietnamese people's diet is healthy?

The way I see that elderly people in Vietnam eat very healthily, they only consume food that low in fat and good for their health. On the other hand, young people have unhealthy lifestyle. They often go out to eat or eat fast food which makes their health worse.
