Freshly ground wheat whole should be kept in the refrigerator and used within two weeks. (The commercial milling process removes most of the fat of wheat. Most white flour is nearly fat free. All wheat flour with a fat content greater than two percent should not be stored.) Any food rancid odor should be discarded. So what we store fat? Flaxseed oil and safflower oil oxidizes very quickly and are not good candidates for storage. The most commonly purchased vegetable oils extracted with heat, pressure, and chemical additives, which can accelerate oxidation. Cold pressed oils are better, though more expensive. You may want to visit Dr. Caldwell Esselstyn, Jr. to increase your knowledge.
I know of no government official shelf life of cold pressed oils. Check carefully for rancid oil before use. The modern diet is high in omega-6 fatty acids and low in omega-3 fatty acids. Meat from animals fed grain and corn and most vegetable oils are rich in omega-6. The National Institutes of Health urges most people to reduce consumption of omega-6 fatty acids and increase consumption of Omega-3 believe that this is critical to achieving optimal brain and cardiovascular functions. Of the commonly used oils, canola oil and soybean oil contain Omega-3 fatty acids. Avocados and nuts, particularly walnuts, are rich in omega-3. Heart Specialist will undoubtedly add to your understanding.
Andrew Weil in his excellent book, eat well for optimum health, promotes olive oil as a healthy substitute for vegetable oils. Has the highest percentage (77%) of monounsaturated fat of any oils, but low in omega-3. There are many varieties of olive oil, each with a slightly different flavor. Choose what you want, but watch it carefully for rancidity. Stored in the refrigerator or a cool basement, olive oil may be clouds – but the quality esafectados. Nutritionists advise eating less trans fats, margarine and shortening. Margarine is not a healthy substitute for butter. Hydrogenated means that the hydrogen atoms were added to stabilize the oil and turn it into a liquid at room temperature to a solid. A saturated fat is a fat that has been saturated with hydrogen atoms, is stable and less prone to oxidation, but the molecular composition of saturated fats is believed to increase levels of serum cholesterol. Store oils and fats – which are essential to a good home ready and a little fat is needed to maintain health. However, choosing the right fats and oils, store them properly, rotate religiously, and discard any that happen to be old.
