Sugar snap peas

Eat at least 2 3/4 lbs of mixed salad and vegetables per day, consisting of "Green-Green” and “Green” foods. Of these, at least 3/4 lb should be mixed salad. Also include at least 5 cups of “Green-Green” leafy vegetables or 2 1/2 cups of other vegetables per week.

The other methods of preserving plant food are to be avoided: Freeze-dried (packet soups), canned (peas, green beans), pickled in salt (gherkins), syruped (fruit jams and jellies), and fermented (sauerkraut). That is not to say you can never eat these things, just do not think that they are proper food. Foods pickled in vinegar (such as onions) have lost many nutrients, but at least the pickling does not add undesirable chemicals.

in 1942, the USDA issued a new food guide that reduced the number of food groups to what they called the "Basic Seven." These were: green and yellow vegetables; oranges, tomatoes, and grapefruit; potatoes and other vegetables and fruit; milk and milk products; meat, poultry, fish, eggs, and dried peas and beans; bread, flour, and cereals; and butter and fortified margarine.
