I would argue that not having to cook would lead to far better health. People eat unhealthy food because it is the most convenient and inexpensive option, not because it is the best option. Wealthy people these days are often in much better health because they can afford good restaurants and private chefs. If you could give yourself an optimized meal plan without having to worry about anything it would be much easier to get in shape. An automatic kitchen along with automated grocery deliveries would be a health revolution.
