Here is a repost from Synger on adding pumpkin and seafood to your diet: (This is from the original superfoods thread)
There have been many lists of "super foods" over the years. Most have many of the same families of things listed, though the specifics may change from list to list -- berries, greens, oats, nuts, tomatoes, broccoli, beans, citrus, deep water fish. Sometimes whole grains and soy are added to the list as well as a few other "regulars" like tea. It's a great way to focus on the healthiest of foods.
On the pumpkin discussion:
Pumpkin stews are really good. Some of them are "served in a pumpkin" which means you make the stew, then put it in a hollowed-out pumpkin, and then bake the whole thing together. As you serve up the stew, you scrape some of the pumpkin flesh into your stew. (much easier than trying to pare and cut up the pumpkin to add to the stew in the first place, though you can do that, too if you want). Here are some stew recipes
For those who do smoothies, pumpkin is a good addition. I use pumpkin butter (like apple butter) instead of jam or jelly, though it's still rather sweet. Often, when I'm going to be baking anyway, I add pumpkin -- pumpkin pancakes, pumpkin muffins.
And of course, one of my absolute favorites is curried pumpkin soup. Very easy to make, too, 'cause it uses canned pumpkin. Here are some pumpkin soup recipes.
As to the Salmon/sidekick discussion:
Sardines are easy to add to salads. Just chop them up. Or mash a few of them into your dressing if you make your own dressing. I like kippered herring with thin slices of onion on Rykrisp crackers. I LOVE herring in sour cream. And of course, albacore tuna is easy to find in the store.
