In regard to living a healthy lifestyle, there's a tremendous amount of information. Frequently, health advocates get too involved with the intricate details of a food or nutrient. When this happens, it tends to lead toward much confusion.
Here's one example: One of my "health hero" doctors, Caldwell Esselstyn, advises not to drink a green smoothie. It's better to eat the whole food. For example, eat the Kale and don't put it in a smoothie.
He had studies that supported his suggestion.
Dr. Esselstyn, with all due respect, most likely, anyone who is consuming a green (veggie) smoothie is living a healthy lifestyle. To dissuade people to stop making them will bog them down with self-doubt and lead them down an erroneous path.
Ironically, another "health hero" of mine, Dr. Doug Lisle, tells us to drink green smoothies.
The moral of the story: If you are leading a healthy lifestyle, do yourself a favor, do not get bogged down with the minute details.
By the way, I can't drink a green smoothie (I love fruit smoothies). However, I love my Kale Chips.
Somewhat related, another "health hero" of mine states: People don’t love nutrients. Nobody says: “I love vitamin C.” But they do say: “I love a fresh orange.” People have feelings about food. They don’t have any feelings about nutrients. - Joan Gussow
