Yes, stress is big. I periodically remind family members to help keep the stress down for my health sake and they do. Also going without needed sleep is stressful. Since I often wake in the middle of the night, I will go to bed at 9 if I can so as to get at least 7 total hours of sleep. With regard to the cost of produce, I get mine at Aldi. If the cost is not too high I buy organic, but otherwise I just make sure to wash the produce well. My daughter, who has a weight problem, started eating more like me and was able to lose over 20 pounds. I buy produce once a week. With regard to GMO food, the big culprits are soy and corn. These are used extensively in processed food and as feed for commercially raised meat.
