Разберете дали има антиоксиданти, как действат и какво значение имат за нашия организъм. Антиоксиданти Антиоксидантите са група химически съединения, които спират или забавят процеса на окисляване на другите вещества. Тяхната основна функция е неутрализирането на вредните за организма свободни радикали, които действат разрушително на нашия организъм. Свободни радикали Свободните радикали, произвеждани в нормални количества, служат на нашия организъм за поддържане на необходимия баланс, между другото, чрез отделяне на вредни токсини. Но, ако има свръхпроизводство, те могат да започнат да унищожават клетките на сърцето, бъбреците, мозъка и на други важни органи, да увреждат нервни клетки, червените кръвни телца, да отслабят имунната система и дори да увредят генетичния материал в клетките, което може да доведе до ракови образувания. Антиоксидантите в диетата Антиоксидантите, доставени с храната, подпомагат естествения защитен механизъм на организма, позволявайки му да запази подходящ баланс. Затова са много важен елемент от диетата. Срещат се най-често в зеленчуците и плодовете.

Витамин А има в броколите, морковите, спанака, млечните продукти, маслото, яйчения жълтък и мазните морски риби. Витамин Е има в растителните мазнини, слънчогледовите семки, орехите, зародишите, царевицата и спанака. Витамин С (аскорбинова киселина) има в цитрусовите плодове, кивито, доматите, червената чушка, брюкселското зеле, магданоза, спанака, френското грозде, шипките и ягодите. Селен има в бразилските орехите,слънчогледовите семена, рибата и морските дарове, чесъна, лука, кафявия ориз, пшеничния зародиш и птичето месо. Полифеноли има в зехтина, гроздето, авокадото, салатата, червеното вино, зеления, червения и белия чай. Консумирайте ги ежедневно Благодарение на антиоксидантите ще запазите здравето и красотата си дълги години. Консумацията на естествени антиоксиданти в ежедневното ви меню спомага за запазване на баланса в организма и намалява риска от много болести на цивилизацията.

Antioxidants have the ability to neutralize the effects of free radicals, these compounds help to dispose of substances harmful to the body of the radical molecules that can damage cells and DNA or collectively, the blueprint of the smallest cells in living things. The types of antioxidants, including vitamin A (beta-carotene), vitamin B, vitamin C, vitamin E, coenzyme Q10, selenium, zinc, and manganese. Vitamin A Vitamin A in the form of beta-carotene gives a yellow color similar to the food plants. The results suggest that women who consume foods containing beta-carotene for approximately 18 months have a risk of some cancers smaller than those who did not. Foods that contain beta-carotene sources are fruits and vegetables that are green, yellow, red, and orange. For example broccoli, tomatoes, spinach, watermelon, potatoes, sprouts, sweet potatoes, pumpkins, and melons. Here is an antioxidant benefits of beta-carotene: Strengthens the skin tissue and prevents acne. Controlling the production of skin oil (sebum). Fight the aging of cells and tissues. Minimize fine wrinkles on the face. Protecting the skin and mucous membranes. Enhance growth and strengthen bones, teeth, and hair. Prevent blindness and strengthen eyesight. Vitamin B Vitamin B is believed to protect the heart and brain from damage with age, helps the human energy metabolism, maintain healthy nervous system, balance hormones, prevent depression, maintain healthy intestines and stomach, prevent infection and help the growth process. Vitamin B complex consists of 8 kinds of Vitamin B1 (thiamin), Vitamin B2 (riboplavin), Vitamin B3 (niacin), vitamin B5 (pantothenic acid), vitamin B6 (pyridoxine), vitamin B12 (cianocabalamin), folic acid, and biotin. Vitamin B6, B12, and folic acid enting in counteracting the effects of aging through the process of methylation or a chemical process that helps maintain the body's DNA and proteins. Addition of vitamin B can help fight acne and skin regenerating ingredients capable of improving blood circulation to the skin tone becomes uneven. Here are a source of vitamin B that is grains, nuts, green vegetables, milk, eggs, fatty fish, red meat, and others. Vitamin C Vitamin C is required for growth, health of body tissues, wound healing, as well as assist in the process of absorption of iron. Vitamin C is important to regulate the rate of metabolism and maintaining body temperature, help the immune system defenses, reducing wrinkles on the face, helps keep blood vessels elastic and strong so as to prevent bruises on the body. Vitamin C is also a source of powerful antioxidants, can improve the smoothness of the skin because it can maintain the collagen in the body. Vitamin E Vitamin E is a nutrient which is soluble in fat but easily broken down by the body. Vitamin E stabilizes oxygen while circulating throughout the body and protect vital components of fat that exist in human cells. Vitamin E are powerful antioxidants to fight free radicals. Researchers have shown that vitamin E has been shown to slow the aging process and boost the immune system. These vitamins keep skin looking toned and glowing, preventing heart disease, arthritis, diabetes, cancer, and help prevent wrinkles. Vitamin E is found in nuts, seeds (sunflower and pumpkin), vegetables (spinach, asparagus, carrots, celery), fruit, olive oil, and so forth. Selenium High levels of selenium that would prevent the body avoid the risk of getting cancer, heart disease. Selenium is an antioxidant, glutathione peroxidase, and works with vitamin E to prevent cell damage from free radicals mmbran, including cataract formation and aging. Food sources that contain lots of selenium include onions, tomatoes, broccoli, cabbage, wheat, soybeans, green beans, tuna and other fish. Zinc Zinc plays a role in the immune system, growth of body cells, tissue elasticity, speed healing, prevent acne, eye care and others. Zinc deficiency can cause the body susceptible to infection, health, declining health, reduced sensitivity to taste and smell, and so forth. Food sources of zinc are producing soy beans, green beans, grains, wheat, and others. Manganese Manganese plays a role in optimizing central nervous system and can help control the activity of a heart attack suddenly. Manganese serves on several enzyme systems, one of antioxidant enzymes superperoksida dismutase (SOD) which is responsible for reducing the effect of cell damage from free radicals and premature aging. Manganese is found in nuts, leafy greens, beets, and wheat. Coenzyme Q10 (ubiquinone) Coenzyme is an essential component of cells and many play a role in producing energy. This coenzyme helps lower blood pressures, boost the immune system, protect the brain and eyes from damage, and help prevent heart disease. This coenzyme is a source of antioxidants and antiaging. Food sources that contain lots of coenzyme Q10 include soy and dairy, fish and dairy, and others.
