Calcium suppose to be good for something and I tend to forget having my sardines with bone.
What to do about it. Hear people use egg shells. Recently saw Arnold Schwarzenegger throw a whole egg with shell in his blender.
Over the last week or so I have collected egg shells in a jar with water together with a lot of salt. Yesterday I took the shells out of the jar, rinsed them well, then put them in the oven to dry and sterilize them. Then into a high speed mixer to turn it all into a fine powder.
Got 100 grams of powder, and put that in my 31 pound meat mixture for pattie making yesterday, and I cannot detect any flavor change. Happy with that. One less nutrient to worry about.
Put my first egg shell in the jar again this morning. Looks like this.
