Sesame Oil


Sesame Oil

Sesame oil comes from an annual herb (Sesamum indicum). The plant is a warm weather plant that grows from the tropics to warm temperate regions. The major producing countries are China, India, Sudan, and Mexico. The seed is 40 to 60 percent oil and is used directly for food when it is cold pressed. The oil is also recovered by mixed expeller and solvent extraction. Sesame paste is a famous food in the lands along the eastern Mediterranean.

Sesame oil has very good oxidative constancy, which is thought to be related to sesamin or another unknown antioxidant in the native oil. When sesame oil is added to other oils for use in frying, the oxidative actions of the recipient oil are improved. The oil is pale yellow and without odor after refining, but also is sold in a darker version for use in Asian cooking.

The fatty acid composition has some similarities to peanut oil in that the levels of oleic acid and linoleic acid are quite similar. Typical composition of sesame oil is 10 percent palmitic acid, 5 percent stearic acid, 41 percent oleic acid, and 43 percent linoleic acid. Typical tocopherol values are 136 mg/kg a-tocopherol and 290 mg/kg Ò¯- tocopherol for a total of 426 mg/kg.

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.

Safeguard the Achilles

One of the most painful tendon injuries is Achilles. But there are also ways to avoid these injuries. Here are some of them: You’ll feel a burning and piercing in the tendon above your heel and it can even make a crackling sound when you move it. Any higher up your calf and it’s more likely that you’ve strained or pulled a muscle. Rupturing your Achilles tendon is a exceptionally painful experience and you’ll know when you’ve done it. Your Achilles tendon connects your calf muscles to your heel bone and is made of thousands of individual fibers of collagen. Restricted blood flow to this area slows repair and pain will worsen if you keep training . Four important factors in healing the Achilles are: rest, ice, compression and elevation. If your tendon is harmed take a break from all weight bearing sport (except swimming) for at least 2 weeks. You can recover from mild injury in a couple of weeks but a severe one can take 5 months. In order to prevent Achilles injury in

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
