Food from the Garden Articles:
Growing grains with small seeds photos and description: amaranth, camelina sativa, chia seed, fonio, kaniwa (canihua), perilla, teff.
Fat from the Garden - suppose that you wanted to grow all of the fat needed for a nutritious diet, but in a backyard garden. Could you do it? Which plants should you choose to grow? This article reviews basic nutrition on essential fatty acids and various possible garden sources of healthy dietary fat.
Lysine Content of 101 Foods - charts and notes - food, total protein in 100 grams of food, total lysine, lysine as a percent of protein, as a percent of ideal, and as a percent of daily need.
Food Storage Articles:
Aflatoxins in Stored Food - important article on toxins produced by fungi improperly stored foods, especially grains, legumes, and nuts.
Food Storage Short List - For any type of food supply or distribution problems, from temporary disruptions in distribution, to shortages, to rationing, even to actual famine, I suggest this approach: (1) BUY some food, (2) STORE some food (3) GROW some food -- BUY, STORE, GROW. This article offers my short list of food items to STORE.
Food Storage - Fat - Fat is an essential nutrient. Fat is essential for the structure and healthy functioning of the human body. The body can make any of the various fats that it needs, as long as it has two essential fatty acids: omega-6 and omega-3. If you are going to store food, be certain to store vegetable oil with both types of essential fatty acids.
Food Storage - Grains - Grains provide a good source of stored protein and carbohydrates. Some grains can be stored almost indefinitely; other grains are only suitable for short-term storage. Grains are relatively inexpensive to buy, and relatively easy to store.
Food Storage - Nuts and Seeds - nuts, seeds, and peanuts provide a good source of stored protein and fat. Their high caloric content makes them a good source of stored food energy. They also provide variety to a grain-based diet.
Food Storage - Legumes - Beans, peas, and lentils provide a good source of stored protein. They also provide the essential amino acid lysine to complement a grain-based diet. Most grains are low in lysine; many legumes are high in lysine.
