Not everyone here on this team agrees on everything and that, of course, is just fine.
Though I am a firm believer in eating a lot of raw foods I also believe that there are some veggies that should also be eaten gently cooked to get even more out of them. I have read in more than one place that cruciferous vegetables (broccoli, cabbage etc.) can be problematic for some people when eaten raw. Gas is the most frequent problem.
You might back off from those raw cruciferous veggies and very gently steam them in a little water. They should still have a firm texture but just softened enough to bite comfortably into--NOT soft.
Also, what Evelyn says is true as well. Our bodies need time to adjust to radical changes. For example: people get gas from beans when beans aren't a regular part of their diet. People who are eating beans 2 or 3 times a week don't usually have that problem.
Also, (Ask Laura, she'll tell you!!) If you are gluten sensitive you will get gas from most grains. When the gluten grains are removed gas goes away. But that is only if you seriously think you are gluten sensitive.
Hospitals are terrific for traumatic care; for acute care. They do a really, really good job in saving lives when it’s a sudden bleeding emergency. But in terms of chronic care, they’re terrible; in terms of the illnesses that most people have, endure, that cost the most money, that last the longest and ultimately die from. -Dr. Andrew Saul
