We've made tremendous progress in the fields of food, health and technology since the Victorian era. And yet we're not nearly as healthy overall as we were then. What gives?

Recent research is showing that not only did people live longer in the late 1800s, but they had strong immune systems too. Of course, there are several differences in the average Victorian diet compared to ours. Here's a rundown:

• They ate more, around 4,500 calories a day for men and 3,000 for women.
• But they also burned more calories, spending their working hours doing hard manual labour.
• Salt, sugar and tobacco weren't as readily available, and were rarely consumed.
  
• They ate between 8-10 servings a day of fresh fruits and veggies.
  
• In fact, all their food was fresh. After all, they didn't have fridges.
  
• They consumed lots of yeast, in both breads and beer. Yeast helps strengthen the immune system.
