This is a story of how 40 g of walnuts becomes 28 g.
BBC's website in their "Health" section has reported that doctors from the Hospital Clinico in Barcelona are recommending eating an ounce (28 g) of walnuts a day to cut the damage from fatty foods. The full story can be found at this link:

Like anyone reading this group, I was suspicious. Ounces in Spain? Nah. Somewhere along the line someone decided to dumb it down from some initial metric value. I was looking for 25 grams, but I was surprised when I found that the original value was actually 40 grams. This must have followed the familiar chain:
"40 grams, eh? How much is that?"
"Er, 1.42857 ounces, sir"
"About an ounce it is!"
"An ounce, sir. Yes sir."
And thus 40 g = 28 g.
Surprisingly, the US sources for this story did not shy away from using grams. They explained the figure not as "about
1.5 ounces" but as 8 shelled walnuts. Somebody out there must be celebrating Metric Week with us.
