These Polyphenols in foods compounds i best-known for their antioxidant and anti-inflammatory properties that help us live our healthiest, happiest, and longest lives possible. And thankfully, they are found in many of our favorite foods. Research shows these powerful plant compounds help stave off free radical damage, UV radiation, and even some types of pathogens —they also have antifungal and antibacterial properties. Polyphenols boost our brain, heart, immune, and digestive health, making the consumption of these compounds an essential component of nourishing ourselves.

Fueling for endurance polyphenols including phenolic acids, flavonoids, catechins, tannins, lignans, stilbenes, and anthocyanidins are widely found in grains, cereals, pulses, Polyphenlls, spices, fruits, chocolates, and beverages like fruit juices, tea, coffee and wine.

The bulk of free radicals that causes damage to biological structures Fopds. Endogenous Polyhpenols of ROS include cytochrome P metabolism, foode reactions, peroxisomes, and inflammatory cell activation.

Excessive intracellular production of ROS builds up cellular Foofs that usually roods damage to lipids, proteins, DNA Polyphenos carbohydrates. Thus, OS has been ln to the pathogenesis of many fiods diseases including brain dysfunction, cancer, inflammatory diseases, heart diseases, diabetes and many others Law et al.

Several antioxidant enzymes such as superoxide dismutase SODcatalase CATand reduced glutathione GSH aid in the removal of free radicals Halliwell and Gutteridge, When not well managed, OS causes extensive chronic and degenerative diseases, the aging process, and acute pathologies like trauma and stroke.

Most importantly, when the production of free radicals overwhelms the antioxidant defenses, it leads to OS, the harmful mechanism that can significantly change cell membranes and other biological structures such as lipoproteins, lipids, proteins, DNA etc.

Genestra, FIGURE 1. Abbreviations: UV: ultraviolet rays, OH: hydroxyl, NO: nitrogen oxide, O2: oxygen, O3: Ozone, H2O2: hydrogen peroxide. Membrane lipids are vulnerable to peroxidative reactions.

Several compounds are formed as a result of lipid polysunsaturated fatty acids PUFA peroxidation, namely isoprostanes, malondialdehyde MDA4-hydroxynonenal 4-HNE etc.

Lobo et al. These compounds are used as biomarkers in lipid peroxidation assays and have been linked to neurodegenerative diseases, heart disease, and diabetes Genestra, ; Lü et al. Peroxynitrite can also destroy lipoproteins and causes lipid peroxidation of cell membranes.

ROS can also affect protein synthesis and protein functions. Protein oxidation can result in amino acid modifications oxidative protein modificationaccumulation of cross-linked reaction products, peptide chain fragmentation, and augmented electrical charges Parthasarathy et al.

Chemical agents that generate oxygen-free radicals like ionizing radiations and activated oxygen cause DNA damage which results in mutations, deletion, and similar lethal genetic effects. Oxidative DNA damage causes the development of various oxidative DNA lesions, which may trigger mutations Halliwell and Gutteridge, Because of DNA disruption, base moieties and sugar become more vulnerable to oxidation, resulting in protein cross-linking, base degradation, and single-strand breakage Zadák et al.

Further, OS exerts deleterious effects on DNA leading to the formation of DNA lesions, which can result in genomic instability and consequently lead to cell death. The guanine a base of DNA is most susceptible to oxidation in cellular OS.

In the presence of ROS, the oxidation of guanosine to 8-oxoguanosine 8-oxoG takes place. The formation of 8-oxoG is the most common lesion in the DNA molecule. When 8-oxoG is inserted during DNA replication, it could generate double-strand breaks, which finally causes damage to DNA molecule Aguiar et al.

Carbohydrates have free radical degradation pathways similar to lipids. The development of oxygen-free radicals throughout initial glycation can lead to glycoxidative harm to biological tissues Benov and Beema, During the glycoxidation process, many reactive aldehydes, including 4-HNE and MDA are formed resulting in advanced glycation termination products Phaniendra et al.

The pathophysiological changes that take place during OS induced diseases are outlined in Figure 2. FIGURE 2. OS induced human diseases and their pathogenesis.

Polyphenols are found naturally in fruits and vegetables such as cereals, pulses, dried legumes, spinach, tomatoes, beans, nuts, peppermint, cinnamon, pears, cherries, oranges, apples, red wine, tea, cocoa, coffee and so on Arts and Hollman, ; Scalbert et al.

Polyphenols are classified into different groups depending on the number of aromatic phenolic rings they contain and the structural elements that connect these rings.

They are broadly grouped into phenolic acids, flavonoids, stilbenes and lignans Khan et al. Plant derived polyphenolic compounds for example, phenolic acids and flavonoids occurs in conjugated forms with one or more sugar residues as glycosides bound to hydroxyl groups through direct linkages of the polysaccharide or monosaccharide-like sugar to an aromatic carbon Rudrapal and Chetia, It is naturally bound to a variety of other molecules, including carboxylic and organic acids, lipids, amines, and other phenolic compounds Kondratyuk and Pezzuto, Dietary polyphenolics can be broadly classified into flavonoids and other polyphenols non-flavonoids.

Flavonoids are further classified into different subgroups based on their structures such as flavanols examples: catechin, epicatechin, epigallocatechinisoflavones examples: genistein, genistin, daidzenin, daidzin, biochanin A, formononetinflavones examples: luteolin, apigenin, chrysinflavonones examples: hesperetin, naringeninflavonols examples: quercetin, kaempferol, galangin, fisetin, myricetinflavononol example: taxifolinflavylium salts examples: cyanidin, cyanin, pelargonidinand flavanones examples: hesperetin, naringenin, eriodictyol, isosakuranetin Pietta, ; Barreca et al.

Non-flavonoid polyphenols can be further classified into phenolic acids examples: cinnamic acid, p -coumaric acid, caffeic acid, ferulic acid, sinapic acid, gentisic acid, vanillic acid, gallic acid, syringic acid, protocatechuic acidtannins examples: procyanidins, catechin, afzelechin, gallocatechin, ellagic acid, gallic acid gallate, gallotannin, ellagitannin, hexahydroxydiphenic acidlignans examples: niranthin, sesamin, silymarin, rubrifloralignan A, bicyclol, phillygenin, clemastanin B, isatindolignanoside A, diphyllin, hinokinin, yatein, secoisolariciresinol etc.

Serrano et al. Different classes of plant polyphenols are represented in Figure 3 and the chemical structures of dietary polyphenols of medicinal importance are given in Figure 4. FIGURE 3. Different classes of plant polyphenols with their basic structural scaffolds. Structural scaffolds represent the chemistry behind various classes of polyphenolic substances.

FIGURE 4. Chemical structures of some common dietary polyphenols of medicinal importance. In plant derived polyphenolic compounds, flavonoids comprise the largest group with an approximately 10, natural analogues.

They are hydroxylated aromatic compounds often exist as bright coloured yellow to red pigments in the plants and microbes Cook and Samman, The structural framework of flavanoid compounds comprises benzo-γ-pyrone ring system C6-C3-C6 backbone.

Structurally, they are characterized as C15 compounds and composed of two phenolic C6 rings which are linked by a bridge of heterocyclic pyrone rings. Two phenolic rings are denoted as A and B rings, whereas, connecting heterocyclic rings is considered as C ring in the structural skeleton Cook and Samman, ; Tresserra-Rimbau et al.

Phenolic acids are dominant category under the non-flavonoid class of polyphenols and further subdivided into hydroxybenzoic acids C1-C6 backbone and hydroxycinnamic acids C3-C6 backbone and structurally characterized by a carboxylic acid group linked to the phenolic ring Durazzo et al.

They generally exist in the plants either in free form or esterified form. They also exist as a conjugate with sugar moiety and proteins often and hydrolysable on acid or alkali treatment. Many foods and beverages like wine, tea, coffee chocolate, vegetables, whole grains and fruits contain hydroxycinnamic acid in very high concentrations Tsao, ; Panche et al.

Stilbenes are biosynthesized by plants during external influence such as infection or injury. They contain C6-C2-C6 backbone and structurally represent 1,2-diphenylethylene nucleus and exist either in the monomeric or oligomeric form.

Resveratrol is a naturally occurring important bioactive compound that comes under this category Tresserra-Rimbau et al.

Like stilbenes, a coumarin type of polyphenols, also synthesize and accumulate in the plant tissues due to the abiotic stress and microbial attacks.

They are composed of 1,2-benzopyrone skeleton α-chromone. They also frequently exist in the prenylated form. Coumarin cores are often used as a template in the synthesis of various pharmacologically important novel compounds Shen et al. Lignans are a comparatively less abundant class of phenolic compounds structurally characterized by a dibenzylbutane skeleton.

These types of compounds are generally found in higher plants gymnosperms, angiosperms, pteridophytes etc. Often they are found in the plant material in bound form and make difficulty in extraction Shen et al. Anthocyanidins are the bright coloured blue, red, or purple pigments flavonoid compounds found in the flowers, fruits and leaves etc.

These are positively charged compounds containing flavylium cations and often occur as chloride salts Shen et al. Anthocyains are composed of one or more sugar moieties in the C-3 position of the C ring.

Frequently these compounds are found in the plants as a conjugate with phenolic acids and other organic acids. The de-glycosylated forms of anthocyanins are called anthocyanidins. Variation in the colour of the anthocyanin compounds is reliant to the pH acylation and methylation -OH groups attached to the A and B ring and also pH of the environment Khoo et al.

Proanthocyanidins are the dimer or trimer of flavanols in condensed form, also known as condensed tannins. Based on the interflavanic linkages, they can be divided as type A C2— O —C7 or C2— O —C5 bondingor type-B C4—C6 or C4—C8.

They often produced from flavanol rich materials during fermentation Khoo et al.

Given lectins' ability to bind to other foods, research suggests that they could disrupt digestion, weaken the intestines, and cause nutrient deficiencies. Polyphenols are compounds naturally found in plant-based foods. They act as antioxidants and may help lower your risk for certain diseases.

Examples of polyphenols include flavonoids, phenolic acid, polyphenolic amides, resveratrol, curcumin, and lignans. The potential health benefits of polyphenols include a lower risk of heart disease, diabetes, cancer, inflammation, and cognitive decline.

Foods that are rich in polyphenols include berries, beans, oats, garlic, spinach, and other plant-based foods.

While you can also get polyphenols from supplements, know that they are not regulated by the FDA. Make sure to talk to your provider before trying one. However, researchers believe eating five or more servings of fruit and vegetables daily will provide enough polyphenols to benefit health.

Research shows polyphenols help support the health of your gut microbiome, which can keep intestines healthy, support digestion, boost the immune system, and support brain health.

9 Polyphenol-Rich Foods (and Drinks)—Plus Healthy Ways to Eat More of Them

You can also enjoy the benefits of polyphenols in a cup of green or black tea, coffee, and even chocolate. Polyphenols are not listed on nutrition fact labels.

Click here for a list of foods with higher amounts of polyphenols. The time is ripe to get your dose of polyphenols this summer. Our favorite Cacao Nib Balsamic Strawberry Salad contains cacao, spinach and strawberries—a plate full of polyphenols!

Nock is a second year Masters student in the Food Science and Human Nutrition program. She is particularly interested in the areas of intuitive eating, mindful eating, non-diet approach, and disordered eating.

A fun fact about Nock is that she really likes to sing and dance! For additional resources to healthy eating, check out these programs from our registered dietitian nutritionists. They have various health benefits, including reducing inflammation and lowering the risk of type 2 diabetes.

Read on to learn more about what foods are high in polyphenols, as well as the possible health benefits of consuming them. The number of polyphenols in a food can vary depending on where the food is grown, how it is farmed and transported, how ripe it is, and how it is cooked or prepared.

Many of the health benefits associated with polyphenols may be related to their role as antioxidants. Antioxidants are known for their ability to combat cell damage. Polyphenols may also impact genes and gene expression.

Polyphenols may even influence gut bacteria. Some researchers have reported that polyphenols may lower the risk for type 2 diabetes. Polyphenols may boost insulin sensitivity, as well as slow down the rate the body digests and absorbs sugar.

According to one review , a type of flavonoid called flavanols may be especially beneficial for lowering insulin resistance. The same review also found that flavonoids seem to be the type of polyphenol most often associated with a lower risk for type 2 diabetes. An analysis of studies on flavonoid intake and type 2 diabetes concluded that people who consumed the most flavonoids had a lower risk of developing type 2 diabetes than those who took in the least.

Increasing flavonoid intake also appeared to be a way to reduce the risk of disease significantly. Unprocessed cocoa is a rich source of flavonoids.

One review found that cocoa consumption significantly decreased a marker of insulin resistance. It is worth noting that unprocessed cocoa is very different from the chocolate in candy bars or traditional desserts.

Unprocessed cocoa comes straight from the cacao plant with no sugar added. A study in animals looked at the effect of green tea polyphenols on measures of inflammation after exercise.

Rats that received the tea polyphenols were able to keep up their activity for longer than the rats that did not receive the polyphenols. They also had significantly lower levels of chemicals that signaled inflammation and muscle damage in their blood.

Lignans are a class of polyphenols that occur at their highest levels in virgin olive oil, flaxseed, and whole grain rye flour. One way to study lignan intake is to look at levels of lignans in urine.

In a study of adults in the United States, researchers found that higher levels of lignans in the urine were associated with lower levels of measures of inflammation. This could be important since long-term inflammation has been associated with certain diseases, such as heart disease and cancer.

A review of studies looked at the impact of cocoa polyphenols on risk factors for heart disease. Scientists found that consuming cocoa for at least 2 weeks led to a significant decrease in blood pressure.

Polyphenol intake may also play a role in body weight regulation. One study compared the intake of flavonoids, a class of polyphenols, with body mass index BMI and waist circumference. Researchers found that a higher flavonoid intake was associated with lower BMI and waist circumference.

These results are significant because obesity is associated with a higher risk for many chronic diseases. Another study found that older adults who drank green tea were less likely to experience cognitive decline than people who drank coffee or black tea.
