Healthy Fats and Oils

Healthy fats and oils are the ones that don't oxidize, or that are typically consumed prior to the oxidizing process. Those fats and oils that are oxidized are either:

not available for use as energy or for structural purposes because they are either in a polymerized not viable form or
they contain toxic components.

Naturally occurring fats and oils have been always consumed. They are habitually found to be the more saturated animal and plant fats. The more readily oxidizable oils historically have usually been consumed in their original packaging in the form of seeds and plants before they have been extracted and had a possibility to form oxidized products.

Oils and fats

Fats and oils to be avoided, in addition to partially hydrogenated vegetable fats, include any rancid or overheated fats and oils that have breakdown products such as oxidized fatty acids, oxidized sterols, peroxides, acrolein, hydrocarbons, and aromatic compounds. These types of abused fats and oils are not secure. Free radicals are derived from the decomposition of unsaturated fatty acids, particularly polyunsaturated fatty acids. Ozone-induced reactive free radicals can interact with sulfhydryl groups in proteins as well as with unsaturated fatty acids and are negative to membranes. Oils, especially the polyunsaturated oils, that have been thought to be good, because they decrease serum cholesterol levels, actually proved to increase cholesterol in tissues; the reason being that the polyunsaturated fatty acids are deposited into the membranes and the body requires to put more cholesterol into these membranes to alleviate them and to preserve the melting point characteristics of the membrane.

Common Signs of Heat Stroke

According to MedicineNet in "Definition of Heat Stroke," heat stroke occurs when the body's core temperature rises above 104°F (40°C) and is accompanied by hot, dry skin and central nervous system abnormalities such as delirium, convulsions or coma. Since heat stroke is a life-threatening condition, it is important to watch people for heat stroke symptoms. MedicineNet states that heat stroke that results from exposure to high environmental temperatures is termed nonexertional heat stroke, and heat stroke that results from strenuous exercise is called exertional heat stroke. Regardless of the type of heat stroke a person experiences, heat stroke signs are life-threatening, and immediate medical attention is necessary when heat stroke symptoms begin. When the body cannot control its temperature, heat stroke occurs because the sweating mechanism fails. The body is not able to cool down. Body temperature can rise to 106°F (41.1°C) or higher within a few minutes. Hea

Causes of Easy Bruising: Reasons Why People Bruise Easily

Bruising , a reddish or purple discoloration under the skin, most often results from trauma to the small blood vessels, called capillaries, but can also occur spontaneously. How and Why Bruises Occur Blood leaks out of the capillaries and accumulates under the skin, gradually absorbing over several days. Bruising most often occurs because people run into objects or experience other trauma. Most bruising is easily explained, but frequent bruising that occurs without obvious cause needs prompt investigation, since several serious diseases can cause bruising. In general, women bruise more easily than men. How Aging Increases the Risk of Easy Bruising Bruising increases as people age for several reasons. Skin thins as people age and the capillaries become more fragile. The layer of fat that cushions blood vessels and protects them from injury becomes thinner as well. Older people often take medications and supplements that thin the blood and contribute to easy bruising. Visi

Stye - Symptoms and Treatment

A stye is an infection, typically a bacterial infection, which causes a painful red lump either on the edge or inside of the eyelid. Bacteria grow at the root of an eyelash follicle or inside an oil gland. The bacteria can be a result of poor hygiene, touching the eyes with unwashed hands or chronic inflammation. The stye resembles a pimple or a boil and is usually filled with pus. A stye does not pose a risk to vision and most often heals without treatment within a week. However, a stye may require treatment with a doctor if the infection does not resolve with at-home remedies. Symptoms of a Stye A stye is not usually hard to spot. Not only does a red lump form on either the top or bottom eyelid, but pain is also an immediate symptom of the condition. Typical symptoms of a stye include: red lump on the eyelid similar to a pimple watering of the eye eyelid pain and swelling clear or yellow fluid collecting in the stye A normal stye will come to a head in approximately three to
