Top Ten Anti-Oxidants

Top Ten Anti-Oxidants

G2

       An antioxidant is a molecule that inhibits the oxidation of other molecules. Oxidation is a chemical reaction that transfers electrons or hydrogen from a substance to an oxidizing agent, which can produce free radicals that can start chain reactions, inducing damage or death to living cells and cancer. Antioxidants terminate these chain reactions by removing free radical intermediates, and inhibit other oxidation reactions. They do this by being oxidized themselves, so antioxidants are often reducing agents such as thiols, ascorbic acid, or polyphenols. Although oxidation reactions are crucial for life, they can also be damaging; plants and animals maintain complex systems of multiple types of antioxidants, such as glutathione, vitamin C, vitamin A, and vitamin E as well as enzymes such as catalase, superoxide dismutase and various peroxidases. Insufficient levels of antioxidants, or inhibition of the antioxidant enzymes, cause oxidative stress and may damage or kill cells. Oxidative stress is damage to cell structure and cell function by overly reactive oxygen-containing molecules and chronic excessive inflammation. The use of antioxidants in pharmacology is intensively studied, particularly as treatments for stroke and neurodegenerative diseases. Antioxidants are widely used in dietary supplements and have been investigated for the prevention of diseases such as cancer, coronary heart disease and even altitude sickness.

  1. Astaxanthin

            Astaxanthin is believed by some sources to be the most powerful antioxidant found in nature. Astaxanthin is found in microalgae, yeast, salmon, trout, krill, shrimp, crayfish, crustaceans, and the feathers of some birds. It provides the red color of salmon meat and the red color of cooked shellfish. Professor Basil Weedon’s group was the first to prove the structure of astaxanthin by synthesis, in 1975. Astaxanthin, unlike several carotenes and one other known carotenoid, is not converted to vitamin A (retinol) in the human body. It is an antioxidant with a slightly lower antioxidant activity in some model systems than other carotenoids. However, in living organisms the free-radical terminating effectiveness of each carotenoid is heavily modified by its lipid solubility, and thus varies with the type of system being protected. The commercial production of astaxanthin comes from both natural and synthetic sources.

  2. Seanol (Ecklonia Cava)

           Seanol is an extremely rare seaweed extract from Ecklonia Cava, proven 100 times more powerful than any land based antioxidant and believed to reduce the effects of aging. Ecklonia cava is a species of brown alga found in the ocean off Japan and Korea. It is used as an herbal remedy in the form of an extract called Seanol, a polyphenol. Another phlorotannin-rich natural agent, Ventol, is also extract from E. cava. One of the phlorotannins component is called fucodiphlorethol G.

  3. Tumeric
    TT1T2T3
           “Anti-Oxidant/Anti-Inflammatory. A plant native to South India and Indonesia, if you like curry or mustard, you’re already familiar with this yellow food. What you might not know is that turmeric — due in large part to curcumin, tumeric’s primary active ingredient — is one of the most powerful anti-oxidants and anti-inflammatories on the planet. The majority of foods we eat, including low fat diets, promote arterial inflammation, which is a leading (and often underrated) cause of heart disease. In the fitness context, exercise-induced physiological stress causes inflammation, which impedes muscular repair. In a general sense, the more quickly the inflammation subsides, the more quickly one recovers from training. Foods like turmeric reduce inflammation, thus expediting recovery (and circulatory health). Extrapolated over time, an athlete on a nutritional regimen high in anti-oxidants and anti-inflammatory foods such as turmeric (buttressed by a predominantly alkaline-forming diet) will in turn be able to train harder, more effectively and more efficiently in a given time period while simultaneously taking out an insurance policy against the primary culprits that foil even the most conscientious athletes — undue fatigue, overtraining and illness. Furthermore, it’s worth noting that there is some evidence to suggest that people who eat diets rich in turmeric have lower rates of breast, prostate, lung, colon and skin cancers. Curcumin can be taken in capsule form, but it is not the most bio-available substance in extract form. Personally, I prefer to drink turmeric in a tea – 1/2 spoonful dissolved in hot water does the trick.” — Tim Ferris

  6. Goji Berries
    GG2G1G3
           Goji berry or wolfberry is the fruit of Lycium barbarum and Lycium chinense, two very closely related species of boxthorn in the family Solanaceae (which also includes the potato, tomato, eggplant, deadly nightshade, chili pepper and tobacco). The two species are native to southeastern Europe and Asia. Goji berries have been used for centuries in traditional Chinese medicine and can be consumed in teas or in berry form. Wolfberries contain many nutrients and phytochemicals including; 11 essential and 22 trace dietary minerals,18 amino acids, 6 essential vitamins, 8 polysaccharides and 6 monosaccharides, 5 unsaturated fatty acids, including the essential fatty acids, linoleic acid and alpha-linolenic acid, beta-sitosterol and other phytosterols, 5 carotenoids, including beta-carotene and zeaxanthin, lutein, lycopene and cryptoxanthin, a xanthophyll, as well as antioxidant properties.

  7. Pomegranate
    PPomegranate heartP2
           The pomegranate, Punica granatum, is a fruit-bearing deciduous shrub or small tree growing between five and eight meters tall. Native to the geographic Kurdistan of modern day Iran and Iraq, the pomegranate has been cultivated in the Caucasus since ancient times. From there it spread to Asian areas such as the Caucasus as well as the Himalayas in Northern India. Today, it is widely cultivated throughout Turkey, Kurdistan, Iran, Syria, Spain, Portugal, Azerbaijan, Armenia, Afghanistan, India, Pakistan, Bangladesh, Iraq, Lebanon, Egypt, China, Burma, Saudi Arabia, Israel, Jordan, Philippines, the drier parts of southeast Asia, the Mediterranean region of Southern Europe, and tropical Africa. Introduced into Latin America and California by Spanish settlers in 1769, pomegranate is also cultivated in parts of California and Arizona for juice production. The pomegranate has been mentioned in many ancient texts, notably the Book of Exodus, the Homeric Hymns and the Quran.

    Nuts are one of the most balanced foods on the planet. They offer a good dose of “healthy” fats along with a smaller amount of protein and carbohydrate. Each type of nut offers a unique profile of minerals, phytochemicals, and types of fat. Walnuts are the highest in plant omega-3s, for example, while Brazil nuts are best for selenium. Most nuts also contain phytochemicals such as resveratrol and plant sterols, which help lower cholesterol.

  10. Kale, Collard Greens and Spinach
    KK2K1
           Kale or borecole is a form of cabbage (Brassica oleracea Acephala Group), green or purple, in which the central leaves do not form a head. It is considered to be closer to wild cabbage than most domesticated forms. The species Brassica oleracea contains a wide array of vegetables, including broccoli, cauliflower, collard greens and brussels sprouts. The cultivar group Acephala also includes spring greens and collard greens, which are extremely similar genetically. Kale is very high in beta carotene, vitamin K, vitamin C, lutein, zeaxanthin, and reasonably rich in calcium. Kale, as with broccoli and other brassicas, contains sulforaphane (particularly when chopped or minced), a chemical with potent anti-cancer properties. Boiling decreases the level of sulforaphane; however, steaming, microwaving, or stir frying do not result in significant loss. Along with other brassica vegetables, kale is also a source of indole-3-carbinol, a chemical which boosts DNA repair in cells and appears to block the growth of cancer cells. Kale is also a good source of carotenoids.

  11. Pu-Erh Tea
    AA2A1
           “This tea can be perhaps the most expensive in the world, with some cakes priced at $350K (for a 250g cake), its leaves derived from trees upwards of 1,700 years old. A post-fermented tea product produced in the Yunnan province of China and carefully aged, the harvesting, creation and ceremony of Pu-erh is an art steeped in preserved tradition dating back millennia. But what makes Pu-erh truly unique is the process by which the leaves are fermented by microbes after drying and then aged. It is believed that the microbial activity in the tea provides probiotic health benefits unique Pu-erh, such as reducing arterial plaque and LDL cholesterol levels as well as aiding in weight loss by reducing blood sugar levels and improving the body’s ability to metabolize fat. Dramatically less costly versions of Pu-erh are available [TIM: I drink this version almost every morning]; versions I have used provide a long-lasting even-keeled energy. To learn more, I suggest you consult your local teahouse. There is nothing like a traditional Pu-erh tea ceremony administered by a tea master. It’s an extraordinary experience. If you happen to be in LA, Colin Hudon at Temple Tea in Venice is excellent.” — Tim Ferris

    Both white and sweet potatoes provide important nutrients such as vitamins C and B6, potassium, and fiber. But sweet potatoes have more of these nutrients. They also bring to the table key nutrients such as calcium and whopping amounts of vitamin A. Other orange vegetables are nutrient-rich and packed with phytochemicals as well. Carrots are famously high in vitamin A, while butternut and acorn squash are tops in vitamins A and C.
