How timely! I was just considering a post on this topic as an unexpected side effect of my surgery. Because I stayed with my parents for two weeks after surgery, my diet changed completely. They are in their mid/late 70s and very vigorous and active.
First of all, my mom eats tons of fruits and veggies daily, plus wild salmon (because it's so easy to get here). Her goal is to eat every color every day. And they made lots of healthy, home-cooked Indian vegetarian food (dal, etc). They do not drink soda and don't have alcohol in the house. No processed carbs or sugary snacks. If my dad had his way he would eat junk and fried food with a beer daily, but my mother is quite strict about it. She's a doctor and obsessed with what different foods do for the body. And it was all delicious thanks to lots of spices!
So we basically ate a super-food diet consisting of: salmon, avocado, oatmeal with cinnamon and raisins, blueberries, cherries, mangoes, kiwi, bananas, apricots, yogurt, cheese, lentils, spinach, peas, broccoli, tomatoes, lots of Indian spices, eggs, wheat toast, almonds and dark chocolate, plus I drank tons of tea and water with lemon juice. This plus walking and resting was so healing that my doctor said I looked 6 weeks healed at my 2 week appointment!
I planned to post about it here because I've made a commitment to stick with this eating plan for the foreseeable future. It's not really a diet, more a way of eating. I don't know if it jives with any of the other food plans out there like paleo or whole foods, but I feel amazing. I don't plan to give up alcohol but getting forcefully weaned from soda and sugar has been great! I'm not going to skip occasional red meat (or BACON!), Thai, Mexican, and other dinners out either... just make as much of a change as I can to what I eat at home.
My boys are total carnivores. I did buy a Spiralizer and both DH and DS have eaten Zoodles twice, so that's a start!
