Becky Ramsing University of Maryland, AAEP A chemical element or substance required in trace (very small) amounts for the normal growth and development of organisms Vitamins and minerals Carbohydrate Protein Fat Enable vital functions in the body ◦ Don’t “fill the belly” Deficiencies ◦ increased illness, poor development and growth, lack of energy, poor school performance Found in common foods When food is scarce, dietary diversity is limited Reliance on staples ◦ Breads ◦ Tea Little or no meats, dairy, fruit, vegetables Energy, growth and development Build blood cells carry oxygen – allowing muscles and brain to work properly Found in animal products, beans and legumes Bone growth and strength Milk products, spinach development of brain and nervous system; insufficient iodine can cause low birth weight, deafness, and cretinism in newborns disease resistance, absorption of iron; help wound healing red and green peppers, strawberries, sweet potatoes, kale, cabbage, broccoli, oranges, mangoes, tomato juice, cauliflower immunity, skin, healthy eyes and lining of gut and lungs sweet potatoes, pumpkin, carrots, spinach, turnip greens, mustard greens, kale, winter squash, cantaloupe, red peppers Carrots were first cultivated in Afghanistan! healthy red blood cells; normal fetal development Spinach, beans, Dark, leafy vegetables Zinc ◦ normal growth and development, immune function B vitamins ◦ conversion of food into energy; helps produce red blood cells, helps nervous system Eat a variety of foods ◦ Colorful fruits and vegetables Grow a variety of foods Eat more ◦ Full serving Add colorful vegetables Add milk products Legumes and nuts or other protein Oil Grains or potatoes Beans and legumes ◦ ◦ ◦ ◦ ◦ ◦ Chick peas Kidney Beans Mung Beans Split Peas Lentils Dairy At least 5 ingredients in dish (soup or stew) Colorful Best fresh - Will lose some nutrients in cooking but depends on method ◦ minerals less sensitive ◦ Vitamins sensitive to heat, light, exposure to air (esp A, C) Keep water that vegetables are boiled in – water soluble vitamins leak into water; can be used to make rice or soups Cook with less water – pressure cooker when available, sauté (fry?) with small amount of oil Cook vitamin A rich foods with a bit of oil Types of vegetable include carrots, pumpkin, squash, turnips, zucchini, onions, leaf lettuce, leeks and radishes. Extend harvest of nutrients ◦ Eg; carrots and pumpkins – summer vs. fall Greens in fall and spring; keep planting lettuce and spinach every 2-3 weeks When ripe (fully developed nutritionally When field temperature is lower – morning, evening ◦ Reducing field temperature by 10 degrees Celsius can double the shelf life! Keep in shade after picking Spread fruit out to allow heat to escape Avoid bruising and cutting Cleanliness – don’t introduce bad bacteria Separate items Don’t cut, leave whole Pack in flat trays or baskets Stop further ripening as appropriate Don’t over-heat, blanch instead of boiling to pre-treat ◦ Best for hard vegetables – carrots, beans, peas ◦ Not for soft – tomatoes, onions, peppers Use prior to drying because it stops enzyme activity, kills bacteria/microbes, and preserves the color with minimal vitamin loss Interact ◦ The more you learn, the better advice you can give ◦ Ask questions instead of telling people what to do. Asking questions allows you to find out what people already know and believe. It makes people take an active part and discuss together traditional beliefs and new concepts. It is more likely to lead eventually to small or large changes in behaviour.
