I have stopped consuming any kind of dairy so I need substitutes for, among the rest, calcium. I've been advised to eat almonds, but I dislike the taste and texture of the raw ones. When I grabbed a bag of roasted almonds in the store, I saw no calcium in the contents. Do the roasted almonds(maybe with added salt or oil) lose the calcium value? Can I roast them by my self to keep the calcium?
Looking at the USDA database, roasting the almonds does not affect the calcium levels (comparing equivalent weights). Look at the value per 100g or value per ounce rather than volume-based values and you'll see what I mean.
Raw almonds average 269mg of calcium per 100g (or 76mg per ounce).
Dry roasted almonds average 268mg of calcium per 100g (also 76mg per ounce).
