>Thurman Fleet,  co-author from the book: Staying Healthy with the Season, has some good  ideas about food.
He  suggests foods to support each  season, and lifestyle.
He also suggests mostly cleansing foods, adequate building foods and lubricators for healthy tissues and skin.
Here is how he breaks it down:
Builders: Animal protein and beans
Cleansers: Fruits and Vegetables
Cogestors: Sweets, cheese, breads
Lubricators: Nuts, seeds and oils
Fruits and veggies: Be aware that fruit and vegetables are cleansers in general, but bananas can have a congesting effect ( so eat 1/2 a banana ). Avocados and mushrooms can also act as builders.
The principal body builders are meat, fish, dairy, nuts beans, seeds and grains- in this order. But remember that many foods listed here can also cause some congestion. Other congestors include noodles, potatoes, bread, cake, cookies, and anything with white flour, sugar, and chemical products.
Do you want to stay strong and live longer?
A diet rich in  body cleansers along with whole grains, some building foods and a limited amount of congertors will keep you clear, strong and well.
Here are some tips for a good spring diet:
Create a spring program with lots of fruits and vegetable juices each day. some examples: citrus fruits, pears, apples, carrots, beets, celery, spinach and parsley.
In general, most fresh fruits and vegetables are good in the spring diet as you lighten up from the heavier, more heat producting diet of the winter months.
GREENS
Greans are a traditional part of a spring diet. They are plentiful in the springtime, and cleansing along with building the body.
You can grown your own greens at home such as wheat grass or alfalfa sprouts. Buy your greens at your local farmers’ market. Support your locals!
Green herbs  include chicory, dandelion and miner’s lettuce.  If you do not know about these plants find someone who can show you where to find them. Take a walk into the country or hillsides to gather greens!
Eat Whole Foods
This includes foods as nature has grown them. They are fresh fruits and vegetables, such as apples, oranges, lettuce and carrots.
Seeds: Such as sunflower and sesame
Nuts: such as almonds, walnuts, pecans
Whole grains: brown rice, millet, rye, oats
Beans: Pinto, mung, lentils, garbanzos
