Boost antioxidant levels -
Another large review of 12 studies found that vitamin E helped reduce blood sugar levels, while vitamin C was effective at decreasing levels of oxidative stress. Antioxidants may be easier to add to your diet than you might think.
Based on ORAC scores provided by Superfoodly based on research from a broad number of sources , below are some of the top antioxidant foods by weight:. The ORAC scores above are based on weight.
This means that it might not be practical to eat high amounts of all of these antioxidant foods. Other high-antioxidant foods not listed above, which are still great sources and highly beneficial, include common foods like:.
Try to consume at least three to four servings daily of these antioxidant-rich foods even more is better for optimal health. Along with antioxidant foods, certain herbs, spices and essential oils derived from nutrient-dense plants are extremely high in healing antioxidant compounds.
Here is another list of the herbs you can try adding to your diet for increased protection against disease. Look for percent pure therapeutic grade oils, which are highest in antioxidants:. Other antioxidant-rich herbs include garlic, cayenne pepper and green tea. Aim to consume two to three servings of these herbs or herbal teas daily.
The American Heart Association, Mayo Clinic and Cleveland Clinic recommend getting antioxidants from whole foods and a wide variety of sources. Glutathione is a peptide consisting of three key amino acids that plays several vital roles in the body, including helping with protein use, creation of enzymes, detoxification, digestion of fats and destruction of cancer cells.
Glutathione peroxidase can prevent lipid peroxidation, which can fight inflammation. Derived naturally from foods like berries and leafy greens, quercetin seems to be safe for almost everyone and poses little risk.
Most studies have found little to no side effects in people eating nutrient-dense diets high in quercetin or taking supplements by mouth short term. Amounts up to milligrams taken twice daily for 12 weeks appear to be very safe for helping manage a number of inflammatory health problems, including heart disease and blood vessel problems, allergies, infections, chronic fatigue and symptoms related to autoimmune disorders like arthritis.
Lutein has benefits for the eyes, skin, arteries, heart and immune system, although food sources of antioxidants seem to be generally more effective and safer than supplements.
Some evidence shows that people who obtain more lutein from their diets experience lower rates of breast, colon, cervical and lung cancers.
Known for improving immunity, vitamin C helps protect against colds, the flu, and potentially cancer, skin and eye problems. Resveratrol is an active ingredient found in cocoa, red grapes and dark berries, such as lingonberries, blueberries, mulberries and bilberries.
Astaxanthin is found in wild-caught salmon and krill and has benefits like reducing age spots, boosting energy levels, supporting joint health and preventing symptoms of ADHD. Selenium is a trace mineral found naturally in the soil that also appears in certain foods, and there are even small amounts in water.
Selenium benefits adrenal and thyroid health and helps protect cognition. It may also fight off viruses, defend against heart disease and slow down symptoms correlated with other serious conditions, like asthma. Chlorophyll is very helpful for detoxification and linked to natural cancer prevention, blocking carcinogenic effects within the body, and protecting DNA from damage caused by toxins or stress.
Cooking can alter the content of antioxidants in food, and certain cooking methods can have a different impact on antioxidant levels. One study published in Preventive Nutrition and Food Science evaluated the effects of different cooking methods on the antioxidant content of red pepper to determine which methods can help minimize antioxidant loss.
Interestingly, researchers found that stir-frying and roasting helped retain the most antioxidants, while boiling and steaming caused significant reductions in antioxidant levels. Ascorbic acid, also known as vitamin C, is a water-soluble vitamin, which means that it dissolves in water. For this reason, cooking food in water with methods like boiling can cause a huge reduction in antioxidant content.
However, not all compounds on the antioxidants list are affected in the same way by cooking. For example, one study found that consuming tomatoes cooked in olive oil significantly enhanced levels of lycopene in the blood by up to 82 percent compared to a control group. Similarly, another study in British Journal of Nutrition showed that stir-frying carrots significantly boosted the absorption of beta-carotene.
For example, because during exercise oxygen consumption can increase by a factor of more than 10, taking high doses of antioxidants might interfere with proper exercise recovery.
When it comes to protection against things like cancer or heart disease, overall the medical literature seems conflicting. Conversely, getting enough sleep on a regular basis can help increase or maintain your levels. Regular physical activity has long been recommended by physicians and healthcare providers.
Recent research shows that exercise is also helpful in maintaining or increasing antioxidant levels, especially glutathione. Completing a combination of both cardio and circuit weight training increases glutathione the most, compared to completing cardio or weight training alone However, athletes who overtrain without maintaining adequate nutrition and rest may be at risk of decreased glutathione production Therefore, be sure to incorporate physical activity into your regular routine in a gradual and sensible way.
Regular physical activity, specifically cardio and weight training, may help increase glutathione levels. However, overtraining without a balanced diet and proper rest can deplete your levels.
Alcoholism is commonly associated with ailments such as liver cirrhosis, brain damage and pancreatitis. While not as well known, lung damage is also an adverse effect of alcoholism.
This is likely related to a depletion of glutathione levels in the lungs. The small airways of the lungs require glutathione to function properly. In fact, healthy lungs have up to 1, times more glutathione than other parts of the body Depletion of glutathione in the lungs of alcoholics is most likely due to oxidative stress caused by chronic alcohol use Thus, limiting your alcohol intake may help you maintain healthy glutathione levels.
Alcoholism decreases glutathione levels throughout the body, especially in the lungs. Glutathione is an important antioxidant that is primarily made by the body, but is also found in dietary sources.
Unfortunately, your levels of this antioxidant can be depleted due to many factors, such as aging, a poor diet and a sedentary lifestyle. Luckily, you can maintain appropriate glutathione levels by increasing your physical activity, avoiding drinking too much alcohol, getting enough sleep and eating a balanced diet.

These free radicals mess with our cellular metabolism, even interfering with our DNA. Our mitochondria, which operate like little factories in our cells, are responsible for burning fuel from food and producing energy in each of our cells via a process called oxidative phosphorylation.
Normally, when an electron separates from a molecule involved in oxidation and reduction, it reattaches almost immediately to another. Under ordinary conditions, this oxidative process creates chemically reactive molecules containing oxygen.
This in turn can lead to the production of molecules of free radicals that are unstable in high concentrations. Not all free radicals are bad.
Free radical formation is crucial to the process of oxidizing nutrients from our food into chemical energy. Free radical accumulation, however, be it atoms, ions or molecules, is harmful and can have severe consequences on our health.
These unstable molecules are detrimental to the proper structure and function of cells throughout the body due to their ability to oxidize cells, known as oxidative stress.
Free radicals damage the growth, development and survival of cells in the body. Their reactive nature allows them to engage in unnecessary side reactions causing cellular impairment and eventually injury when they are present in disproportionate amounts.
They directly impair cell membranes and DNA. This leads to cell mutation and causes new cells to grow erroneously, which means free radicals are associated with both development of cancer as well as the progression of aging. Free radicals are frequently implicated with health problems that are experienced with age, such as hardened arteries, diabetes and even wrinkle formation.
Overeating further increases free radical production. As we eat more, our mitochondria release more activated oxygen than normal during energy consumption, thus generating higher levels of free radicals. And, risk of oxidative stress is greater when certain types of foods are consumed and the degree of danger can be influenced by the way in which they are prepared or cooked.
