In the nuts and seeds category we analyzed 90 different products, with antioxidant contents varying from 0.03 mmol/100 g in poppy seeds to 33.3 mmol/100 g in walnuts, with pellicle and purchased with nut shell intact. Pecans with pellicle, sunflower seeds and chestnuts with pellicle, have mean antioxidant content in the range of 4.7 to 8.5 mmol/100 g (Table (Table3).3). Walnuts, chestnuts, peanuts, hazelnuts and almonds have higher values when analyzed with the pellicle intact compared to without pellicle.
Various types of chocolate were analyzed, from milk chocolate to dark chocolate and baking cocoa. The variation of antioxidant content in chocolate ranged from 0.23 in white chocolate to 14.98 mmol/100 g in one individual dark chocolate sample. Mean antioxidant contents increased with increasing content of cocoa in the chocolate product (Pearson correlation r = 0.927, p < 0.001). Chocolate products with cocoa contents of 24-30%, 40-65% and 70-99% had mean antioxidant contents of 1.8, 7.2 and 10.9 mmol/100 g, respectively.
With this study we present a comprehensive survey of the total antioxidant capacity in foods. Earlier small-scale studies from other laboratories have included from a few up to a few hundred samples [20-22,29-31], and in 2007 the U.S. Department of Agriculture presented the Oxygen Radical Absorbance Capacity (ORAC) of Selected Foods report including 277 food samples . These studies have been done using different antioxidant assays for measuring antioxidant capacity making it difficult to compare whole lists of foods, products and product categories. Still, a food that has a high total antioxidant capacity using one antioxidant assay will most likely also be high using another assay [20-22]. Consequently, the exact value will be different but the ranking of the products will be mainly the same whichever assay is used. In the present extensive study, the same validated method has been used on all samples, resulting in comparable measures, thus enabling us to present a complete picture of the relative antioxidant potential of the samples.
Dark chocolate's potent antioxidant content—along with some of the other mechanisms of nutrients—make it a treat for your immune system. Cocoa can modulate the inflammatory response of your immune system. Inflammation is tissue's response to pathogens, chemicals, wounding, or infections. Flavonoids are generally associated with anti-inflammatory properties, and chocolate is filled with them.
What your dentist told you when you were a kid is true. “Oral bacteria love sugar just like we do, and when they feast on it, acid gets released as a byproduct,” says Dr. Sanda Moldovan, DDS. “This acid attacks the enamel of the teeth and allows bacteria to penetrate into the deeper layer of the tooth structure, called dentin.” The more sugar you eat, the more acidic the mouth becomes and the faster cavities develop. Plus, sugar feeds yeast growth, which might make the corners of your mouth or tongue red. “This also comes with a velcro-like feeling, or sensitivity to spicy foods,” she says. The sugar link is also a reason why diabetes is one of the diseases your teeth can reveal.
If you have diabetes, too much sugar can lead to kidney damage. The kidneys play an important role in filtering your blood sugar. Once blood sugar levels reach a certain amount, the kidneys start to let excess sugar into your urine. If left uncontrolled, diabetes can damage the kidneys, which prevents them from doing their job in filtering out waste in your blood. This can lead to kidney failure.
My kids typically make good food choices on their own and have become rather adventurous eaters since they aren’t restricted or expected to only consume chicken fingers or hamburgers when we aren’t at home. For instance, my two year old loves broccoli, olives, sardines and other healthy foods. Make the good foods readily available and make the unhealthy ones few and far between…
For a report published in the Journal of Agricultural and Food Chemistry in 2004, scientists from the U.S. Department of Agriculture (USDA) performed what is considered to be the most comprehensive analysis of the antioxidant content of commonly consumed foods. The USDA scientists ranked these foods according to their total antioxidant capacity, which is a measure of the antioxidants' ability to neutralize free radicals.
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.
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."
