Preventing Cellular Damage With Antioxidants!

What are antioxidants?
Antioxidants are intimately involved in the prevention of cellular damage, the common pathway for cancer, aging, and a variety of diseases. The scientific community has begun to unveil some of the mysteries surrounding this topic, and the media has begun whetting our thirst for knowledge.
Why are athletes so keen on Antioxidants?
Athletes have a keen interest because of health concerns and the prospect of enhanced performance and/or recovery from exercise. The purpose of this article is to serve as a beginners guide to what antioxidants are and to briefly review their role in exercise and general health. What follows is only the tip of the iceberg in this dynamic and interesting subject.
What Causes Aging?
Scientists have discovered that the metabolic rate of animals is related to their life span. Therefore, larger animals do not consume as much oxygen per unit of body mass as smaller animals, and larger animals live longer. Consequently, researchers believe that aging is connected with oxygen metabolism and involves free radicals. Thus, the faster oxygen is consumed by an organism, the more free radicals it might make.
Antioxidant Role
Antioxidants are molecules which can safely interact with free radicals and terminate the chain reaction before vital molecules are damaged. Although there are several enzyme systems within the body that scavenge free radicals, the principle micronutrient (vitamin) antioxidants are vitamin E, beta-carotene, and vitamin C. Additionally, selenium, a trace metal that is required for proper function of one of the body's antioxidant enzyme systems, is sometimes included in this category. The body cannot manufacture these micronutrients so they must be supplied in the diet.
What Vitamins Contain High Antioxidants?
Vitamin E: d-alpha tocopherol. A fat soluble vitamin present in nuts, seeds, vegetable and fish oils, whole grains (esp. wheat germ), fortified cereals, and apricots. Current recommended daily allowance (RDA) is 15 IU per day for men and 12 IU per day for women.
Vitamin C: Ascorbic acid is a water soluble vitamin present in citrus fruits and juices, green peppers, cabbage, spinach, broccoli, kale, cantaloupe, kiwi, and strawberries. The RDA is 60 mg per day. Intake above 2000 mg may be associated with adverse side effects in some individuals.
Beta-carotene is a precursor to vitamin A (retinol) and is present in liver, egg yolk, milk, butter, spinach, carrots, squash, broccoli, yams, tomato, cantaloupe, peaches, and grains. Because beta-carotene is converted to vitamin A by the body there is no set requirement.
So, remember to take the right vitamins in order to maintain optimum health! Antioxidant supplements is the easy way to ensuring that our body is getting sufficient supply of antioxidants!

Lice
By: nagalie | 22-07-2008
I am so grossed out, tired, and aggrivated. I need help. I need some feedback. To begin with, I'm an ultra clean person but I think I have lice. I am not sure. for a week now I have been itching like crazy but didn't find anything until today. I can never find anything at will. Nothing in the seems of my clothes. I only feel them. anyway, today I found on my arm ( think it fell from my head) what I now know looks like lice according to pictures i've seen. It had 6 legs was a transparent brown exept for the dark insides of its body. It was about the size of the period at the end of this sentence but a bit larger including it's legs...(Sooo sorry that you are getting this gross info but it's quite necessary for the process of identifying my problem.) Anyway, I am pretty sure it is lice but the question i want to ask now is what kind? If it is body lice it should be treated different from head lice I think. I know you can get rid of head lice with olive oil but body lice? Here are my symptoms... I am 90% sure I got this from my dog who was in some tall grass the other day. I saw her itching intensely but shes never had any bites before so I didnt think about it. I thought it was allergies and gave her a benedryl. THEN I started itching along with her. I know its not fleas. I don't think its scabies because my bites dont run in lines or around the webbing of my fingers. Not only that but scabies dont look like lice from what I know. Now, I can't tell if it is head or body lice because of this, they are both on my head and on my body. I even feel them in my eyelashes. I have them in my nether regions...and I've never had sex.lol I have bites that look like pimples all spread out on my legs...nether region...round my belly button, on my behind, back and neck. None on my chest or face thank God for that. But head lice are supposed to remain on the head for all I know and body lice on the body. I even feel itchy in my ears. I can barely sleep. Someone help me so I can search for a remedy pleeease. If you have a remedy for either please share it with me . Thanks
