Mr. bean, I don't feel you been getting a lot of respect lately.
You are a great source of fibre, protein and carbs as well as many nutrients.
You are low GI and provide long lasting energy.
You are loaded with antioxidents, black beans in particular.
And you are cheap - nothing personal!
What are your main downsides?
Mainly phylates, lectins and flatulence, flatus or gas - as it is commonlly called.
Phylates: can chelate minerals reducing their bio-availability.
Solutions: soaking and cooking well or spouting reduces about half the content.
Also serving with yogurt (lactobacillus) may provide enough phytase enzyme to digest the phylates - tastes good anyway!
Perhaps more appropriate as a mid-day snack so it doesn't interfere with main meal nutrient absorption.
Lectins: can damage intestinal linings in people who are sensitive.
They are found in 30% of all food, not just wheat and beans, but dairy, meat, tubers, grains and seeds. They vary
in strength.
Solutions: Cooking reduces levels quite a bit. Avoid the strongest lectins in castor, soybeans and red kidney beans.
Fermenting reduces levels, so fermented soy/bean products are better.
Certain sugars bind with and block the action of lectins, and supplements have been built around this.
Intestinal linings are weakest during illness, so reducing intake at those times seems appropriate even if not senstive.
Gas: Caused by bacterial action on the high fibre content probably.
Solutions: Soaking, cooking well and chewing well should help make the fibre more easily "digested" by the bacteria and reduce gas.
Beano, Mr. bean's friend.
What do you think of the bean, and how do you use it? Do you feel it can provide good sports nutrition?
I think it's worth considering. Additional suggestions or contrary opinions welcome...
