The aim of the present study was to screen foods to identify total antioxidant capacity of fruits, vegetables, beverages, spices and herbs in addition to common everyday foods. In nutritional epidemiologic and intervention studies, the Antioxidant Food Database may be utilized to identify and rank diets and subjects with regard to antioxidant intake and as a tool in planning dietary antioxidant interventions. The database will be available online at the University of Oslo's web site.
Good news for all chocolate lovers! Chocolate is actually quite healthy so no need to feel guilty indulging in your chocolate love every now and then. Dark chocolates and cocoa pack a big antioxidant punch and are rich in flavanols and polyphenols. A popular study conducted by Harvard experts and published in the online Journal Heart suggests that is actually good for your heart especially, the one with 70% cocoa. Too much chocolate can, of course, add to you daily calorific intake so moderation is the key here.
While we all like to indulge once in a while, foods that quickly affect blood sugar contribute to a greater risk of obesity, heart disease, and diabetes.1 Emerging research also suggests connections between these high-glycemic diets and various forms of cancer.2,3,4 These effects are often a result of added sugars working in your body, so be sure to read those nutrition labels.
The Antioxidant Food Table is a valuable research contribution, expanding the research evidence base for plant-based nutritional research and may be utilized in epidemiological studies where reported food intakes can be assigned antioxidant values. It can also be used to test antioxidant effects and synergy in experimental animal and cell studies or in human clinical trials. The ultimate goal of this research is to combine these strategies in order to understand the role of dietary phytochemical antioxidants in the prevention of cancer, cardiovascular diseases, diabetes and other chronic diseases related to oxidative stress.
Plants are humanity's greatest ally in the fight against climate change. Plants soak up carbon dioxide and turn it into leaves and branches. The more trees humans plant, the less heat-trapping carbon pollution in the air. Unfortunately, plants require a lot of water and land, so much that humans might need a new to find a new ally to help draw down all that carbon.
Initial studies have been carried out to examine the association between intake of antioxidant rich foods and their health effects [67,70]. Some of these studies describe a beneficial effect on oxidative stress related chronic diseases, e.g. from intake of nuts [49,69], pomegranates [71-73], tomatoes , coffee , tea [54,75,76], red wine [77-79] and cocoa . The highly reactive and bioactive phytochemical antioxidants are postulated to in part explain the protective effect of plant foods. An optimal mixture of different antioxidants with complementary mechanisms of action and different redox potentials is postulated to work in synergistic interactions. Still, it is not likely that all antioxidant-rich foods are good sources and that all antioxidants provided in the diet are bioactive. Bioavailability differs greatly from one phytochemical to another [26,27,80], so the most antioxidant rich foods in our diet are not necessarily those leading to the highest concentrations of active metabolites in target tissues. The antioxidants obtained from foods include many different molecular compounds and families with different chemical and biological properties that may affect absorption, transport and excretion, cellular uptake and metabolism, and eventually their effects on oxidative stress in various cellular compartments . Biochemically active phytochemicals found in plant-based foods also have many powerful biological properties which are not necessarily correlated with their antioxidant capacity, including acting as inducers of antioxidant defense mechanisms in vivo or as gene expression modulators. Thus a food low in antioxidant content may have beneficial health effects due to other food components or phytochemicals executing bioactivity through other mechanisms.
Due to the higher cocoa content, dark chocolate has a much richer flavor than milk chocolate. The higher the percentage of cocoa, the richer the taste. Cocoa is naturally bitter and very strong-tasting. Chocolate-makers (especially makers of milk chocolate) mellow this flavor by processes, such as alkalizing, fermenting, roasting, and adding milk and/or sugar, all of which can destroy healthy flavanols, alter our ability to use them or negate their health effects all together with unhealthy additives.
Because you’re not getting any real nutrients when you eat sugar, you may still feel hungry. One Australian study found that higher refined sugar intake was associated with an inability to realize you’re full. Plus, with sweet drinks, “calories from sugar in liquid form are not thought to be satiating, and people are not able to fully account for the calories that were consumed in liquid form with a compensatory reduction in calories at subsequent meals,” Dr. Malik says. So, you may end up eating more calories overall. Here are 50 “healthy” snacks that are secretly bad for you.
According to Harvard University, a systolic pressure under 120 (the first number) and a diastolic pressure under 80 (the second number) is considered normal. Hypertension, or high blood pressure, is indicated by a systolic pressure of 140 or higher and/or a diastolic pressure of 90 or higher. Before and during the challenge Herbert had normal numbers and there was no reason for concern.
Considering that heart disease is the number one killer and that dark chocolate has been shown to substantially reduce risk of cardiovascular disease, I believe regular chocolate consumption can be a good thing. Always choose above 70-percent cacao and select your brand wisely so as to keep your cadmium, lead, and sugar low while maximizing the antioxidant and flavonol benefits.
All kinds of beans – black, pinto, red and kidney beans are high-octane sources of antioxidants. Beans are also rich in muscle-boosting protein, have no cholesterol and little fat. Combing them with grains helps in making them a complete protein. Use them in salads, sandwiches or to make famous Punjabi Rajma. If you find them difficult to digest, drink a lot of fluids through the day.
“Dr. David Reuben, author of Everything You Always Wanted to Know About Nutrition says, “white refined sugar-is not a food. It is a pure chemical extracted from plant sources, purer in fact than cocaine, which it resembles in many ways. Its true name is sucrose and its chemical formula is C12H22O11. It has 12 carbon atoms, 22 hydrogen atoms, 11 oxygen atoms, and absolutely nothing else to offer.” …The chemical formula for cocaine is C17H21NO4. Sugar’s formula again is C12H22O11. For all practical purposes, the difference is that sugar is missing the “N”, or nitrogen atom.”

Herbert had softer stool for all the days of the challenge, and on seven out of the 14 days she went to the bathroom more than once. "This is not normal for me, but everything was 'smoother'. I started using Xylitol [a sweetener] towards the end, but it upset my stomach. This was a side-effect that made it more difficult to sustain the challenge."
Rich in nutrients – Chocolate with a high content of cocoa is loaded with nutrients, including a soluble fiber while also rich in iron, magnesium, copper, manganese, and potassium. Dark chocolate also contains a slight amount of mono- and polyunsaturated fats – good fats – which are shown to reduce cholesterol levels and decrease the risk of heart disease.
The Western lifestyle — with its processed foods, reliance on medications, and high exposure to chemicals or environmental pollutants — seems to lay the foundation for the proliferation of free radicals. Because many of us are exposed to such high rates of oxidative stress from a young age, more than ever we need the power of antioxidants, which means we need to consume high antioxidant foods.
A plant-based diet protects against chronic oxidative stress-related diseases. Dietary plants contain variable chemical families and amounts of antioxidants. It has been hypothesized that plant antioxidants may contribute to the beneficial health effects of dietary plants. Our objective was to develop a comprehensive food database consisting of the total antioxidant content of typical foods as well as other dietary items such as traditional medicine plants, herbs and spices and dietary supplements. This database is intended for use in a wide range of nutritional research, from in vitro and cell and animal studies, to clinical trials and nutritional epidemiological studies.
The world’s love affair with chocolate has only grown over the years. We love it drizzled on ice cream, mixed with warm milk for a delicious beverage, or combined with nuts and caramel for a tempting treat. Chocolate remains one of our favorite indulgences; Americans eat around $18.27 billion worth of chocolate every year—nearly 18 percent of the world’s chocolate confectionary, according to 2015 statistics released by Euromonitor International. And as culinary artists continue to create new ways to experiment with cocoa, dark chocolate has grown in popularity as a rich and intense alternative to milk chocolate.
Excessive sugar consumption can cause long-term damage to skin proteins, collagen and elastin, leading to premature wrinkles and ageing. Too much sugar could also contribute to an imbalance of the female menstrual hormones which could result in acne along the jaw line. Sugar is also the favourite food of less desirable gut bacteria and yeast, and consuming too much could lead to an imbalanced gut flora and inflammation in the body, typically seen in skin conditions such as eczema.
Small-scale studies have indicated for quite some time that regular intake of cocoa can have a positive effect in fighting cardiovascular disease. A more recent study on cocoa's cardiovascular benefits, done in 2006, proved this among a larger study group of 470 men, all tested while consuming different daily doses of cocoa. The conclusions were that cocoa does indeed lower the chances and significance of cardiovascular disease.
An excerpt of the 425 spices and herbs analyzed in our study are presented in Table Table5.5. The study includes spices and herbs from 59 different manufacturers or countries. Twenty seven single products are in the range 100 to 465 mmol/100 g, but the variation is from 0.08 mmol/100 g in raw garlic paste procured in Japan, to 465 mmol/100 g in dried and ground clove purchased in Norway. Sorted by antioxidant content, clove has the highest mean antioxidant value, followed by peppermint, allspice, cinnamon, oregano, thyme, sage, rosemary, saffron and estragon, all dried and ground, with mean values ranging from 44 to 277 mmol/100 g. When analyzed in fresh samples compared to dried, oregano, rosemary and thyme have lower values, in the range of 2.2 to 5.6 mmol/100 g. This is also true for basil, chives, dill and parsley. In addition to common spices and culinary herbs, we have also analyzed other herbs, like birch leaves, wild marjoram and wood cranesbill among others. Details on all herbs can be found in Additional file 1, the Antioxidant Food Table.
The average American consumes roughly 12 pounds of chocolate each year, and over $75 billion is spent annually worldwide on chocolate. (1) There is a lot of chocolate eating going on regularly, which is why I want to help you make the smart, healthy choice. That way you can have your chocolate without guilt and with health benefits of dark chocolate to boot!
Allen, R. R., Carson, L., Kwik-Uribe, C., Evans, E. M., & Erdman, J. W.,. (2008, April). Daily consumption of a dark chocolate containing flavanols and added sterol esters affects cardiovascular risk factors in a normotensive population with elevated cholesterol. [Abstract]. Journal of Nutrition. 138(4):725-31. Retrieved from http://www.ncbi.nlm.nih.gov/pubmed/18356327
Chocolate’s lengthy history is believed to go all the way back to 1900 B.C. This is when the the Aztec civilization believed that cacao seeds were a gift of Quetzalcoatl, the god of wisdom. They used the seeds to prepare a bitter, frothy beverage that also included spices, wine or corn puree. (22) It was very different from today’s super sweet milk chocolate treats but closer to a very minimally processed dark chocolate made from raw cacao.
Cranberries are not just another staple on the American Holiday table. They pack some serious antioxidant punch and are also well known for their beneficial effect on preventing urinary tract infections. Try 100% cranberry juice diluted in water or sparkling water for a refreshing, tart drink, or add some unsweetened dried cranberries to your trail mix.
Ahh, the soothing bliss of chocolate! Do you crave that milky brown sweetness, that molten cocoa, sugar and milk mixture melting in your mouth? Do you satiate that craving, only to feel utterly betrayed and guilty for having participated in consuming something so sinfully delicious? Dark chocolate is here for you! This rich treat is an excellent substitute for milk chocolate – the high-in-sugar chocolate most people consume! Dark chocolate, however, is full with a lot of more nutrients and can prove positive for your health. It is one of the best sources that contains antioxidants in the world, coming from the seed of the cocoa tree, often with higher cocoa content than other chocolates. In fact, the antioxidants in cocoa can help you fight against heart disease, some cancers and even diabetes.
Forget carrots—dark chocolate can improve your eyesight too, according to research published in the journal Physiology & Behavior. The researchers found that participants who consumed dark chocolate with 720 mg of cocoa flavanols experienced enhanced visual performance—like detecting motion and reading low contrast letters—likely due to the increased blood flow to the retina and brain.
As a colleague and I alluded to in the New York Times, sugar, not salt, is the true addictive white crystal. Indeed, sugar meets the definition of an addictive substance in animals, hitting all the checkboxes for being a substance of abuse including reward, tolerance, bingeing, and withdrawal. And as I show in my book, The Salt Fix, salt may actually be an antidote to sugar addiction.
Studies on brain activity have provided evidence supporting the idea that overeating alters our brain’s reward system, which then further drives overeating. This same process is thought to underlie the tolerance associated with addiction. Over time, greater amounts of the substance are required to reach the same level of reward. Studies imply that overeating results in a diminished reward response and a progressively worsening addiction to low-nutrient foods rich in sugar, salt, and fat.
Such observational studies don't prove that chocolate is responsible for these benefits. However, the consistent and repeated positive results in studies done on cocoa indicate that chocolate does have a positive effect on the cardiovascular system. Chocolate has had such a profound effect on so many systems in the human body some authorities are unsure whether to call it a food or a drug.
Herbal and traditional plant medicines emerged as many of the highest antioxidant-containing products in our study. We speculate that the high inherent antioxidant property of many plants is an important contributor to the herb's medicinal qualities. In our study we identified Sangre de Grado, the sap from the tree trunk of the species Croton lechleri sampled in Peru to have exceptional high antioxidant content. This sap has a long history of indigenous use in South America for wound healing and as an antifungal, antiseptic, antiviral and antihaemorrhagic medicine. Proanthocyanidins are major constituents of this sap  and studies have shown that Sangre de Grado limits the transcription of a wide range of pro-inflammatory cytokines and mediators and accelerates the healing of stomach ulcers [33,34] and promotes apoptosis in cancer cells . Other extreme antioxidant rich herbal medicines are Triphala, an Indian Ayurvedic herbal formulation, shown to have anti-inflammatory activity , antibacterial and wound healing properties [37,38] and cancer chemopreventive potential . Arjuna, another Auyrvedic formula, has been shown to have health beneficial activities [40,41] while Goshuyu-tou, a traditional Chinese kampo medicine has been shown to significantly reduce the extracellular concentration of NO in the LPS-stimulated Raw 264.7 cells .
Just empty and quickly digested calories that actually pull minerals from the body during digestion. It creates a hormone cascade when consumed that starts a positive feedback loop in the body to encourage more consumption. In a time when food was scarce and needed to be contained in large amounts in the summer when available to survive the winter, this was a good thing. In today’s world of constant access to processed foods, this natural biological purpose highlights one of the negative effects of sugar. Here’s why:
Dark chocolate is made from cacao or cocoa. All chocolate starts as harvested cacao beans from the plant’s seed pods. Once harvested, the cacao beans are typically fermented and dried before being sent off to factories for further production. Pure cacao and pure cocoa powder both have antioxidants and health benefits. However, raw cacao powder is different because it does not undergo any heating and therefore has more nutrients and health properties. Raw cacao powder is made by cold-pressing unroasted cocoa beans so it retains more of its natural goodness while cocoa powder is typically heated at much higher temperatures. Dutched cocoa also gets washed in a potassium solution that neutralizes its acidity, which gives it a darker color and a more mellow flavor. (13)
In the brain, excess sugar impairs both our cognitive skills and our self-control (having a little sugar stimulates a craving for more). Sugar has drug-like effects in the reward center of the brain. Scientists have proposed that sweet foods—along with salty and fatty foods—can produce addiction-like effects in the human brain, driving loss of self-control, overeating, and subsequent weight gain.
Interestingly, the antioxidant content in human breast milk is comparable to that in pomegranate juice, strawberries and coffee and on average higher than the antioxidant content observed in the commercially available infant formulas analyzed in our study. Breakfast cereals are also potential important sources of antioxidants; some of these products have antioxidant contents comparable to berries, which are fairly high, compared to other grain products and may be due to antioxidants added to the products in fortification process.
Aviram M, Rosenblat M, Gaitini D, Nitecki S, Hoffman A, Dornfeld L, Volkova N, Presser D, Attias J, Liker H, Hayek T. Pomegranate juice consumption for 3 years by patients with carotid artery stenosis reduces common carotid intima-media thickness, blood pressure and LDL oxidation. Clin Nutr. 2004;23:423–433. doi: 10.1016/j.clnu.2003.10.002. [PubMed] [CrossRef]
A study conducted at the University of Oslo in Norway compiled 3,100 food items using the FRAP assay method of measurement, which extracts the antioxidant value of foods and beverages with the scale of millimoles/100 grams. Millimoles are 1/1000 of a mole (a unit of measurement that allows the conversion between atoms/molecules and grams). Using this measurement, antioxidant values are compared on a scale. The FRAP assay is said to be an inexpensive and easy way to measure antioxidant content.
So what did the study show? The researchers found that the flavanol content of cocoa powder (30.1 milligrams per gram) was significantly greater than all of the other super fruit powders. It was also revealed that dark chocolate’s antioxidant capacity was higher than all of the super fruit juices except pomegranate. The total polyphenol content per serving was also highest for dark chocolate (about 1,000 milligrams per serving), which was significantly higher than all of the fruit juices except pomegranate juice. (11)
- Cut one source of sugar each week. If the thought of drastically reducing your sugar intake makes you nervous, take a gradual approach. Start cutting sugary treats a little at a time. Cut dessert to one or two days a week. Stop adding sugar to your coffee. Skip the weekly office donut tray. This gives you a chance to adjust to less sugar over time.
It’s important to purchase the best dark chocolate you can find. The majority of chocolate on the market is garbage, with very little nutritional value, so always look for the quality stuff with more that 70% cocoa. A lot of places now offer organic dark chocolate, which is even better for you since it reduces that possibilities of eating bad chemicals.
That’s why one bite of ice cream never feels like enough and before you know it, you’re looking at the bottom of a pint. Or why you find McDonald’s french fries so hard to resist—the ingredient list includes both dextrose, an added sugar, and fat in the form of canola oil, corn oil, soybean oil and hydrogenated soybean oil. Dip those fries in ketchup and you’re getting even more sugar—this time high fructose corn syrup.
Dark chocolate may have something in common with carrots: Researchers from the University of Reading in England tested the eyesight of 30 healthy adults, 18 to 25 years old, after they ate white and dark chocolates. The subjects performed better on vision tests after eating the dark chocolate. It could be that the flavanols in dark chocolate, which improve blood flow to the brain, improve blood flow to the retina as well — and white chocolate doesn’t have nearly the same amount of flavanols as dark chocolate.
The FRAP assay of Benzie and Strain  was used with minor modifications that allowed quantification of most water- and fat-soluble antioxidants [16,17]. A Technicon RA 1000 system (Technicon instruments corporation, New York, USA) was used for the measurements of absorption changes that appear when the TPTZ-Fe3+ complex reduces to the TPTZ-Fe2+ form in the presence of antioxidants. An intense blue color with absorption maximum at 593 nm develops. The measurements were performed at 600 nm after 4 min incubation. An aqueous solution of 500 μmol/L FeSO4 × 7 H2O was used for calibration of the instrument. Validation of the assay is described in Halvorsen et al. 2002 . Briefly, the within-day repeatability measured as relative standard deviation (RSD) in standard solutions ranged from 0.4% to 6%. The between-day repeatability was < 3%. The variation in the values for replicate food items obtained from the same source were typically between 3 and 10 RSD%.
Fructose—the sugar that naturally occurs in fruit and is a component, with glucose, of high fructose corn syrup (HFCS) and table sugar—lights up the brain's reward center, says pediatric endocrinologist Robert Lustig, MD, of UCSF Benioff Children's Hospital in San Francisco. But over time, a diet packed with fructose (especially from HFCS) can make it tougher to learn and remember, animal research suggests. To stay in peak mental shape, try sticking with savory snacks.
It’s helpful to understand a little about how sugar is used by the brain. The carbohydrates you eat, including sugars, are broken down into glucose. Your brain needs glucose to function properly. Unfortunately, many people eat much more sugar than they need. According to the Department of Health and Human Services, the average American eats the equivalent of about 42 teaspoons of sugar a day. That added sugar comes from various sources, such as table sugar, baked goods, and sugary drinks.
