Antioxidants Dietary basics by Andrew Hamilton. Antioxidant protection for athletes: is it time to ditch the pills? During the last decade, research into antioxidant nutrition and athletic performance has been one of the most rapidly evolving areas of sports nutrition.

But while many athletes take antioxidant supplements, the most recent research suggests that there may be more effective approaches to protecting the athletic body.

Andrew Sheaff looks at brand new research suggesting that scientists have been wrong about one of the most fundamental guidelines for This property can be of great importance for reducing haemolysis induced by intense physical exertion [ 44 , 45 ].

In the current study, the antioxidant potential of administered chokeberry juice was determined using two methods, DPPH and ABTS, as 8.

This indicates that the antioxidant potential of the juice was relatively low compared with that of chokeberry extracts and fresh fruit [ 46 ].

This might explain the lack of statistically significant effects of chokeberry supplementation in the current study. In the current study, the chokeberry juice had no effect on free radical damage, as determined by the measurements of TBARS and 8-OHdG levels Table 5.

Petrovic et al. The supplementation resulted in small changes in the lipid profile and in reduced TBARS levels in blood; however, these changes were observed only in men. By contrast, Cikiriz et al. However, the composition of the supplement and its antioxidant potential were not described in that study [ 47 ].

Intriguingly, García-Flores et al. This combination of ingredients significantly reduced post-exercise changes in the levels of DNA damage markers determined in the plasma and urine [ 48 ]. The above changes were observed with juice with the anthocyanin content of In the current study, the amount of anthocyanins was four times higher, i.

Hence, it is likely that a combination of polyphenols, rather than the anthocyanin content, plays a role in reducing DNA damage.

Analysis of the available literature indicates that the advantage of compounds derived from chokeberry is their comprehensive effect on both the immune system and reduction of oxidative stress, including the ability to chelate iron ions, which seems to be a key element not only for iron management.

For this reason, we expected it to reduce markers of oxidative stress. We therefore expected chokeberry juice supplementation to reduce oxidative stress markers.

However, we observed a statistically insignificant reduction of the average values of oxidative stress markers tested after the second beep test after supplementation in both, the supplemented and control groups. Zügel et al. The authors showed that the levels of hepcidin and ferritin, acute-phase proteins, were a sensitive indicator of changes in the training load exercise volume and intensity.

In the current study, football players were subjected to the same training load throughout the entire study period, which probably explains the lack of statistically significant differences in the levels of hepcidin and ferritin. In another study [ 50 ], the effect of physical exercise and supplementation with juice high in polyphenols containing chokeberry extract, among other ingredients on hepcidin levels was analysed in a group of triathletes of both sexes.

According to a cell line-based study, anthocyanins are inserted into the outer part of the erythrocyte membrane [ 52 ]. Their presence in the hydrophilic part of the membrane forms a protective shield against free radicals, among others, thus rendering them safe and effective antioxidants.

Probably this fact may be explained by the decreased level of iron compared to the control group [ 52 ]. Iron ion chelation by active compounds present in chokeberry [ 53 ] might counteract muscle fibre damage. However, in the current study, we did not observe significant changes in the levels of myoglobin, a marker of muscle fibre damage.

Anthocyanins modulate inflammation, both because of their ability to sequester iron [ 54 ] and because of their regulation of various components of the immune system involved in the development of inflammation [ 55 ]. For instance, Ohgami et al.

The authors also observed that the number of inflammatory cells, protein concentration, and levels of NO, pyrogenic prostaglandin E2, and tumour necrosis factor α in the aqueous humour in animal groups treated with crude chokeberry extract were significantly reduced, and the effect size was dose-dependent [ 56 ].

Consequently, standardization of the content of anthocyanin compounds, which play a key health-protective role, in chokeberry products should be considered for their use. In addition, participant play position or volume of competition play starters vs. non-starters was not considered in the randomization process in the current study.

These factors should be addressed in future studies. In addition, subject compliance was not controlled. Implementation of a web-based app with reminders of the supplementation time and dosage might potentially resolve this problem.

This could be explained by both, good adaptation of the athletes to the applied exercise load and the insufficient antioxidant capacity of the chokeberry juice tested.

Further research should consider the supply of chokeberry in a more concentrated form, e. as a concentrate or lyophilizate, to compare the effects of chokeberry supplement types e.

juice, concentrate, mixtures or of various levels of antioxidant potential. Extremely intensive physical exercise can potentially lead to excessive muscle damage, which would decrease training progress. Hence, future research should examine the possible mitigating effects of chokeberry juice on muscle damage and training progress improvement.

Gowtham Srinivas September 23, What Role Do Antioxidants Play in Supporting an Athletic Body? Introduction: Are you an athlete or aspiring to be one? The Importance of Antioxidants: Antioxidants, as the name suggests, are compounds that help combat the harmful effects of oxidative stress in our bodies.

Supporting Athletic Performance: Antioxidants play a vital role in supporting athletic performance by offering a range of benefits: Reduced Muscle Damage: Intense exercise can lead to the production of free radicals, causing muscle damage and fatigue.

Antioxidants help neutralize these free radicals, reducing muscle damage and promoting faster recovery. Enhanced Recovery: Athletes often push their bodies to the limit, resulting in inflammation and oxidative stress. Antioxidants help reduce inflammation and promote faster recovery, allowing athletes to bounce back stronger for their next training session or competition.

Improved Immune Function: Strenuous exercise can temporarily weaken the immune system, making athletes more susceptible to infections and illnesses. Antioxidants help boost immune function, reducing the risk of illness and ensuring athletes can maintain their training schedules.

Optimized Energy Production: Antioxidants assist in maintaining optimal energy production by protecting mitochondria — the powerhouses of our cells. This ensures that athletes have the necessary energy to perform at their best during training and competitions.

Turmeric: Widely used in Indian cuisine, turmeric contains curcumin — a powerful antioxidant with anti-inflammatory properties that can help enhance recovery and reduce exercise-induced muscle damage. Colorful Fruits and Vegetables: Include a variety of brightly colored fruits and vegetables like spinach, carrots, tomatoes, and berries in your diet.

These vibrant foods are rich in antioxidants like Vitamin A, C, and various phytochemicals that support overall health and well-being. Conclusion: In conclusion, antioxidants play a crucial role in supporting an athletic body by reducing muscle damage, promoting recovery, boosting immune function, and optimizing energy production.

: Antioxidant-Rich Athletic Performance

Antioxidant-Carotene-rich multi | Pacific Center for Naturopathic Medicine	Beets supply naturally occurring, nonsynthetic nitrates that are converted to nitric oxide, which increases vasodilation. Blood vessels relax and widen during vasodilation. With wider blood vessels, more oxygen-rich blood flows through the body and reaches muscles sooner; this allows muscles to work at a high intensity for longer periods of time. Increased blood flow also helps to dissipate the heat created during physical activity. Elite athletes have long tried to find ways to increase vasodilation, including through illegal substances. Consuming beets and beet juice currently is popular with athletes. And while there's been strong evidence that beets and beet juice improve athletic performance, more recent research has been less conclusive. Juicing beets leads to a greater concentration of the beneficial components, but requires an expensive at-home juicer. Clients can purchase packaged, store-bought juice, though this also can be pricey. Powdered beet supplements are available for athletes, but the jury is still out on their effectiveness. Diced beets can be added to salads, and roasted beets can make an excellent side dish. According to a Harvard study, cacao, the bean from which chocolate is made, is associated with increased blood flow because of the positive effect flavanols have on the nitric oxide system. There's some evidence that dark chocolate has benefits on performance as well, possibly via this mechanism. These foods are nutrient dense and easy to incorporate into the diet as snacks or sides. Some athletes may take large supplemental doses of vitamin C, which results in poor absorption. It's mostly lost in the urine and isn't supported by evidence. Turnips, beets, mustard greens, and asparagus are good sources and are very low in total calories. Nuts and seeds make great snacks and also can be added to main dishes and salads. They're calorically dense, so educating clients about appropriate serving size is important. Berries Berries are nutrient dense and antioxidant rich, as they contain both anthocyanins and flavonols. Smoothies made with frozen berries are common beverages among athletes because they make excellent and fast postworkout meals or snacks. Frozen berries also keep much longer than fresh berries. Berries are very low in calories and can be added to breakfast foods like pancakes, oatmeal, or yogurt. Tart cherries also are popular with athletes and can be eaten whole or juiced, and added to frozen desserts that are calorically dense for those with very high energy needs. Leafy Greens The antioxidant count and nutrient density of leafy greens is unmatched. The serving size of cooked greens is one-half cup. A hungry athlete easily can eat two cups in one sitting, therefore consuming four servings of antioxidants. Sautéed greens can be added to many meals like stir-fries, burritos, and wraps. Arugula is especially rich in nitrates, containing more than beets. Called salad rocket in Europe, this spicy, leafy green can be eaten raw in salads or added to tacos. Fiber Antioxidant-rich foods most often come packed with significant amounts of fiber. The benefits of fiber are clear and undisputed, but large amounts can be problematic for individuals who aren't used to eating several grams in one sitting. For example, too much fiber can negatively impact performance by moving stool through the gastrointestinal GI tract too fast during physical activity. Nevertheless, some athletes on plant-based diets consume upwards of g per day without GI issues. If a client has a low-fiber diet, gradually increase high-fiber foods to give the GI tract time to adjust. If GI distress is a concern for athletic clients, consider reducing the total number of grams of fiber consumed within the three to four days leading up to a big event. Counseling Athletes Athletes tend to be motivated and interested in nutrition, which can be both a plus and minus for dietitians who work with them. Often, advice must be accompanied with rationale related to performance. Athletes are influenced by a variety of factors including coaches, supplement manufacturers, employees at nutrition stores such as GNC, celebrity athletes with promotional contracts, and well-meaning family members. Dietitians are in a perfect position to explain the science behind antioxidant-rich foods and supplementation associated with athletic performance and other nutrition recommendations. Evidence on the benefits of antioxidant-rich foods for performance is still mixed, but we do know that these foods are beneficial for overall individual health, and this includes athletes. The thinking was simple: if exercise produces increased free radical damage in the body — for example in the muscles that are working during exercise — can an increased intake of antioxidants ameliorate that damage, helping to protect muscle tissue from excessive breakdown, thereby speeding recovery? BOX 1: WHAT IS FREE RADICAL DAMAGE? These free radicals are fleeting but extremely reactive chemical species, which unavoidably occur during oxygen metabolism when fats, proteins and carbohydrates are combined with oxygen in the body to produce energy aerobic metabolism. Athletes process and use larger volumes of oxygen and at higher rates than the majority of the population; this explains why many scientists have assumed that they may benefit from higher intakes of antioxidant nutrients to bolster defences. Unsurprisingly perhaps, there are now dozens of antioxidant supplements on the market, some of which are aimed squarely at endurance sportsmen and women such as cyclists, runners, swimmers, triathletes etc. The reasoning is that these types of athletes might need greater antioxidant support because during long training sessions, their bodies process a lot more oxygen and generate more free radicals than the average couch potato. FIGURE 1: FREE RADICAL DAMAGE TO DNA Schematic and simplified representation of free radical damage. The free radical is generated through normal oxygen metabolism — for example in the muscle during aerobic exercise. It encounters a strand of DNA and steals an electron to become stable. However, removing the electron from the DNA molecule has resulted in damaged DNA, which now does not function as it should. The rush to research It was following the discovery back in that exercise increases free radical production in muscles, that the interest in antioxidant nutrition ballooned. Over the next 30 years, the rate of research into exercise and antioxidants would increase fold see figure 2! And with such a huge and growing amount of research, some of the initial assumptions about the role of antioxidants in human health and exercise were overturned. Bars depict numbers of reports published in individual years; arrow highlights the year exercise was shown to increase free radical content in muscle. The early and middle years The early research into muscle damage and antioxidants this area was rather mixed. Some studies on supplementing antioxidants in this nutrients had produced inconclusive results Eur J Appl Physiol , 92 : Int J Sports Med , 23 1 : , while others had reported positive results Int J Sport Nutr Exerc Metab , 11 4 : Free Radic Biol Med , 36 8 : Am J Physiol ;R—9. Some of the research that followed however was more convincing. For example, a American study on vitamin C supplementation and delayed onset muscle soreness DOMS , found that taking three grams of vitamin C per day 1g morning, noon and night for two weeks prior to a heavy exercise session and for four days afterwards, significantly reduced soreness Int J of Sport Nutr Exerc Metab , 16; Also, the subjects experienced less muscle breakdown and had lower markers of free radical damage. In more recent years, a number of other studies on supplementing antioxidant nutrients in sportsmen and women have shown quite positive results in terms of reducing markers of muscle damage. For example, a study on the effects of cysteine an amino acid building block that contains the element sulphur, which gives it powerful antioxidant activity and the cysteine-related antioxidants taurine, alpha lipoic acid and N-acetyl cysteine NAC found that they boosted the activity of protective antioxidant enzymes in the body and lowered markers of free radical damage J Physiol Sci. The protective effect of alpha lipoic acid was also confirmed by a more recent study, which found taking alpha lipoic acid, significantly reduced muscle DNA damage after resistance training Med Sci Sports Exerc. Other antioxidant supplements that have been studied recently and have been shown to help reduce markers of free radical damage following exercise include methylsulfonylmethane often abbreviated to MSM in runners J Sports Med Phys Fitness. The problem is that very little if any evidence had emerged showing any performance benefits. Indeed, the next step in this story came when in , when two studies were published showing that certain antioxidants not only failed to enhance endurance performance, but actually made it worse! In one of these studies, researchers investigated the performance effects of a powerful sulphur-containing antioxidant called N-acetyl cysteine NAC during high-intensity interval exercise and selfpaced minute time-trial performance in nine trained cyclists Appl Physiol Nutr Metab. When they had supplemented with the placebo, the cyclists managed to maintain an average power output of watts. But when they had supplemented with the NAC, this fell to just watts — a very significant drop see figure 3 also. Right: Average power output during the time trial fell by 4. In the second study, Twenty-three trained female runners completed three blocks of high-intensity training for 3. In each of these periods, they supplemented either with vitamin C mgs , blackcurrant juice or an inert placebo drink Eur J Sport Sci. The results showed that the vitamin C-supplemented block resulted in lower average running speeds during training, while the blackcurrant-supplemented block showed a slight trend to faster speeds. The researchers cautioned that athletes should not take large amounts of vitamin C routinely as it seems to diminish training adaptation. Is it time to love free radicals? Around the same time as the above studies, two further studies showed why taking large amounts of antioxidants might harm performance. A second study looked at how NAC supplementation affected muscle performance Am J Clin Nutr. In this study, subjects performed eccentric contractions of the quadriceps muscle of the frontal thigh to deliberately produce muscle damage and soreness! After this, they were given an inert placebo or 20mg per kilo of bodyweight of NAC. The good news was that supplementing NAC did help reduce muscle damage following the exercise. The bad news was that the NAC supplements also blunted the release of some key signalling molecules that are involved in muscle adaptation. Likewise, other studies found that other popular antioxidant supplements such as quercitin and resveratrol blunted the positive effects of exercise training — probably because they too interfere with important signalling pathways Scand J Med Sci Sports. doi: Although free radicals and free radical damage have become dirty phrases in nutrition, it seems that Nature in her infinite wisdom has actually designed our bodies to harness the activity of these free radicals produced during exercise in order to switch on the production of molecules that orchestrate the process of muscle repair and adaptation — both in terms of strength and endurance. In other words, it now seems that we need some exerciseinduced free radical damage because without it, our muscles are unable to adapt effectively to training stimuli. Well, some of the most recent research suggests that we might be able to have our antioxidant cake and eat it!

It is especially pertinent in athlete health and injury prevention. Athletes of all skill levels and ages rely on their bodies to perform at their best, making the consumption of nutrient-rich foods a critical component of their overall well-being. In this article, we discuss the relationship between nutrient-rich foods and athlete health, with a focus on injury prevention. These nutrients play a pivotal role in supporting immune function, improving recovery potential, and most importantly, preventing injuries among athletes. A diet that is abundant in lean proteins, fruits, vegetables, whole grains, and healthy fats provides the body with the fuel it needs to maintain its resilience against the strains of training and competition. One of the key factors in injury prevention among athletes is maintaining strong and healthy muscles. Essential nutrients like protein, vitamin D, calcium, and magnesium are paramount for muscle development, repair, and function. Nutrients such as calcium, vitamin D, vitamin K, and magnesium are essential for bone health. Intense physical training can lead to increased inflammation and compromised immunity among athletes. You can learn more about the dangers of over-training here. However, a diet rich in antioxidants, found abundantly in fruits and vegetables, can help mitigate inflammation and boost the immune system.

Finally, no significant changes in the body weight, body mass index BMI , and adipose tissue were observed after supplementation in any group Table 7. They postulate that the production of ROS and the damage to cells may be an important part of the training process for athletes, and supplementation may interfere. If GI distress is a concern for athletic clients, consider reducing the total number of grams of fiber consumed within the three to four days leading up to a big event.

So if an athlete weighs 75 kgs, at maximum, their daily protein requirement will be gm which can easily be fulfilled. Antioxidants, as the name suggests, are compounds that help combat the harmful effects of oxidative stress in our bodies. Further Reading. The researchers found that the supplements had no benefit on the prevention of heart-related deaths, and Ruscigno suggests that the same may be true for athletic performance.
Pacific Center for Naturopathic Medicine	They reduce the risks of many degenerative conditions, including heart disease, several types of cancer, diabetes, cataracts, macular degeneration, arthritis, and skin damage. Antioxidants, including vitamins C and E and the mineral selenium , enhance exercise performance, as shown in many studies where they were examined individually and collectively. They prevent exercise-induced oxidative damage to muscle tissues, caused by free radicals that form with increased metabolism and tissue stress during exercise. Antioxidant supplementation has been shown to improve physical performance in deficient subjects, and further studies are expected on elite athletes. This is injury to the fatty layer of cell membranes and other important fats such as myelin wrappings around brain cells, and it can be exacerbated by the physiological stress of exercise. Antioxidants also protect against muscle tissue damage. They provide particular protective benefits for exercise training in older athletes. Natural carotenes are a group of red, orange, and yellow pigments found in the chloroplasts and chromoplasts of plants including fruits, vegetables, algae, and whole grains. They shield plants from sun-induced free radical damage, providing powerful protection for a lifetime in the sun. Plant carotenoids are water-soluble and do not accumulate in our bodies, so toxicity is almost unheard of. More than five hundred carotenoids are known, some of which convert into active vitamin A in our tissues. For athletes, we recommend carotenes only in the natural mixed form which are safest and most effective when derived from food sources, and never synthetic beta-carotene which has been shown to be relatively ineffective and potentially risky. We recommend the full range of purely natural carotenoids, including carotene isomers, alpha-carotene, zeaxanthin, cryptoxanthin and lutein, which are all potent antioxidants. Carotenes, along with lutein and other antioxidants, protect all cells and tissues including muscles and connective tissues from scavenging free radicals. They reduce oxidative stress and cell damage, and decrease harmful lipid peroxides. These enzymes neutralize cell damage from superoxide, a major type of harmful reactive oxygen species that increases with high-intensity exercise. B-complex vitamins are essential for the metabolism of carbohydrates, fats, and protein, and for energy production during exercise. They are also key for adrenal and thyroid function, both of which have to work at peak levels for endurance and stamina. B vitamins are also needed to form hemoglobin, the molecule in red blood cells which delivers oxygen to the muscles, for which there is greater demand during aerobic or endurance exercise. Bars depict numbers of reports published in individual years; arrow highlights the year exercise was shown to increase free radical content in muscle. The early and middle years The early research into muscle damage and antioxidants this area was rather mixed. Some studies on supplementing antioxidants in this nutrients had produced inconclusive results Eur J Appl Physiol , 92 : Int J Sports Med , 23 1 : , while others had reported positive results Int J Sport Nutr Exerc Metab , 11 4 : Free Radic Biol Med , 36 8 : Am J Physiol ;R—9. Some of the research that followed however was more convincing. For example, a American study on vitamin C supplementation and delayed onset muscle soreness DOMS , found that taking three grams of vitamin C per day 1g morning, noon and night for two weeks prior to a heavy exercise session and for four days afterwards, significantly reduced soreness Int J of Sport Nutr Exerc Metab , 16; Also, the subjects experienced less muscle breakdown and had lower markers of free radical damage. In more recent years, a number of other studies on supplementing antioxidant nutrients in sportsmen and women have shown quite positive results in terms of reducing markers of muscle damage. For example, a study on the effects of cysteine an amino acid building block that contains the element sulphur, which gives it powerful antioxidant activity and the cysteine-related antioxidants taurine, alpha lipoic acid and N-acetyl cysteine NAC found that they boosted the activity of protective antioxidant enzymes in the body and lowered markers of free radical damage J Physiol Sci. The protective effect of alpha lipoic acid was also confirmed by a more recent study, which found taking alpha lipoic acid, significantly reduced muscle DNA damage after resistance training Med Sci Sports Exerc. Other antioxidant supplements that have been studied recently and have been shown to help reduce markers of free radical damage following exercise include methylsulfonylmethane often abbreviated to MSM in runners J Sports Med Phys Fitness. The problem is that very little if any evidence had emerged showing any performance benefits. Indeed, the next step in this story came when in , when two studies were published showing that certain antioxidants not only failed to enhance endurance performance, but actually made it worse! In one of these studies, researchers investigated the performance effects of a powerful sulphur-containing antioxidant called N-acetyl cysteine NAC during high-intensity interval exercise and selfpaced minute time-trial performance in nine trained cyclists Appl Physiol Nutr Metab. When they had supplemented with the placebo, the cyclists managed to maintain an average power output of watts. But when they had supplemented with the NAC, this fell to just watts — a very significant drop see figure 3 also. Right: Average power output during the time trial fell by 4. In the second study, Twenty-three trained female runners completed three blocks of high-intensity training for 3. In each of these periods, they supplemented either with vitamin C mgs , blackcurrant juice or an inert placebo drink Eur J Sport Sci. The results showed that the vitamin C-supplemented block resulted in lower average running speeds during training, while the blackcurrant-supplemented block showed a slight trend to faster speeds. The researchers cautioned that athletes should not take large amounts of vitamin C routinely as it seems to diminish training adaptation. Is it time to love free radicals? Around the same time as the above studies, two further studies showed why taking large amounts of antioxidants might harm performance. A second study looked at how NAC supplementation affected muscle performance Am J Clin Nutr. In this study, subjects performed eccentric contractions of the quadriceps muscle of the frontal thigh to deliberately produce muscle damage and soreness! After this, they were given an inert placebo or 20mg per kilo of bodyweight of NAC. The good news was that supplementing NAC did help reduce muscle damage following the exercise. The bad news was that the NAC supplements also blunted the release of some key signalling molecules that are involved in muscle adaptation. Likewise, other studies found that other popular antioxidant supplements such as quercitin and resveratrol blunted the positive effects of exercise training — probably because they too interfere with important signalling pathways Scand J Med Sci Sports. doi: Although free radicals and free radical damage have become dirty phrases in nutrition, it seems that Nature in her infinite wisdom has actually designed our bodies to harness the activity of these free radicals produced during exercise in order to switch on the production of molecules that orchestrate the process of muscle repair and adaptation — both in terms of strength and endurance. In other words, it now seems that we need some exerciseinduced free radical damage because without it, our muscles are unable to adapt effectively to training stimuli. Well, some of the most recent research suggests that we might be able to have our antioxidant cake and eat it! Read More Functional foods: too much to swallow?

Energy cakes Gatosport. Electrolyte drinks 0 kcal. Packs promo. Food supplements. Massage creams. New Products. Every day, the body is subjected to a variety of stresses from its surroundings: pollution, muscle activity during physical labour or a sports activity, tissue inflammation, ageing, stress, and so on.

These aggressions caused by our surroundings lead to the production of free radicals, which can destroy our cells and damage our body; in practical terms, this means poor recovery, fatigue, injuries.

Physical activity increases the production of free radicals. But not to worry: at the same time, the body raises its defences by producing antioxidants to protect itself 1.

Even so, those who do not get enough antioxidants through their diet, will not be as capable of protecting themselves against free radicals. Antioxidants are molecules that can be both produced by the body and introduced through our diet. Antioxidants are present in food in a variety of forms: vitamins C, E, A, Omega-3s, zinc, and many other lesser-known micronutrients.

One of the main roles mentioned in the SU. MAX study 3 is a reduction in the risk of the onset of cancer and cardiovascular diseases in humans thanks to regular consumption of fruits and vegetables rich in antioxidants and fibres. Antioxidants also play the role of protecting cells by stopping the harmful action of free radicals those generated when the body is under stress.

Antioxidants such as vitamin E and the Omega-3s found in oily fish and dressing oils help, for instance, lower inflammation and allergies…. These include flavonoids widespread among plants , tannins found in cocoa, coffee, tea, grapes, etc. Similarly, starting with the amino acid cysteine, our body can produce a powerful antioxidant called α-lipoic acid or lipoate.

its ability to withstand oxidation, is expressed using a value called the ORAC unit Oxygen Radical Absorbance Capacity. Free radicals are created by the degradation of oxygen by our cells. Blood resting TAC had a small correlation with total antioxidant intake correlation.

Most other dietary intakes had trivial associations with antioxidant biomarkers. Hopkins is with the Inst of Sport and Recreation Research, Auckland University of Technology, Auckland, New Zealand. Lowe is with the School of Applied Science, Bay of Plenty Polytechnic, Tauranga, New Zealand.
