The antioxidant measurements have been conducted over a period of eight years, from 2000 to 2008. The samples were procured from local stores and markets in Scandinavia, USA and Europe and from the African, Asian and South American continents. Many of the samples of plant material, like berries, mushrooms and herbs, were handpicked. Commercially procured food samples were stored according to the description on the packing and analyzed within four weeks. Handpicked samples were either stored at 4°C and analyzed within three days or frozen at -20°C and analyzed within four weeks. Products that needed preparation such as coffee, tea, processed vegetables etc. were prepared on the day of analysis. Furthermore, all samples were homogenized, dry samples were pulverized and solid samples were chopped in a food processor. After homogenizing, analytical aliquots were weighed. Included in the database are 1113 of the food samples obtained from the US Department of Agriculture National Food and Nutrient Analysis Program. They were collected, homogenized, and stored as previously described . Three replicates were weighed out for each sample. All samples were extracted in water/methanol, except vegetable oils which were extracted in 2-propanol and some fat-rich samples which were extracted in water/2-propanol. The extracts were mixed, sonicated in ice water bath for 15 min, mixed once more and centrifuged in 1.5 mL tubes at 12.402 × g for 2 min at 4°C. The concentration of antioxidants was measured in triplicate of the supernatant of the centrifuged samples.
Things get a little bumpy when the liver becomes full of glycogen due to excessive refined sugar consumption. When you eat too much sugar, the fructose levels build up, and the liver eventually turns them to fat. That fat can get stuck in the liver, which causes non-alcoholic fatty liver. In other words, excessive sugar consumption can eventually have the same

The occasional candy or cookie can give you a quick burst of energy (or “sugar high”) by raising your blood sugar levels fast. When your levels drop as your cells absorb the sugar, you may feel jittery and anxious (a.k.a. the dreaded “sugar crash”). But if you’re reaching into the candy jar too often, sugar starts to have an effect on your mood beyond that 3 p.m. slump: Studies have linked a high sugar intake to a greater risk of depression in adults.
All types of eggplant are rich in bitter chlorogenic acid, which protects against the buildup of heart-threatening plaque in artery walls (and fights cancer, too!), say USDA scientists in Beltsville, Maryland. In lab studies, eggplant lowered cholesterol and helped artery walls relax, which can cut your risk of high blood pressure. Here are some more foods that can help lower your blood pressure.
An ongoing 40-year study on the effects of chocolate on cognitive function was recently finished. The study used data from the beginning of the study and compared it through cross-sectional study. This might not mean that chocolate makes people smarter—perhaps smart people happen to eat chocolate. Regardless, the study also concluded that all the types of intelligence measured previously were increased by chocolate consumption—along with spoken word recall.
In moderation (one ounce or less per day), dark chocolate has been shown to improve so many common and chronic health problems. With all of its natural and health-promoting components (like flavonoids, polyphenols and flavanols), dark chocolate is an antioxidant powerhouse and a superfood that’s truly a joy to eat. It’s been shown to boost heart and brain health, along with fight disease — just some of the many benefits of dark chocolate.
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.
Efforts to mimic nature’s antioxidants have largely failed. In fact, some antioxidant supplements, such as vitamin E and beta-carotene, are even harmful to health in large doses. The National Center for Complementary and Integrative Health (NCCIH) recommends, “Do not use antioxidant supplements to replace a healthy diet or conventional medical care, or as a reason to postpone seeing a healthcare provider about a medical problem. If you are considering a dietary supplement, first get information on it from reliable sources.” Dietary supplements contain active ingredients, so always check for interactions with your medications.
This tiny powerhouse is rich in beta-carotene, an antioxidant that protects against lung cancer and helps maintain healthy skin, hair, nails, gums, glands, bones, and teeth. It’s also a good source of vitamin E, which may help prevent heart attacks, stokes, and lower the risk of death from bladder cancer. Here are the things every woman should know about bladder cancer.
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…
When it comes to protection against things like cancer or heart disease, overall the medical literature seems conflicting. Although some studies found a positive relationship between antioxidant supplementation and risk reduction, others have not found such positive effects. (15) To be safe, always follow directions carefully and speak with your doctor if you’re unsure of whether or not a supplement is right for you. And to remain your healthiest into older age, aim to reduce free radical load in your body by practicing things like:
Feeling a bit sluggish? Consider snacking on a square or two of dark chocolate—the darker, the better. A study published in NeuroRegulation found that chocolate containing cacao amounts above 60 percent can have significant stimulatory effects on the brain, which can make you more alert and attentive. (See “Cacao vs. Cocoa” sidebar.) Although researchers aren’t quite sure why cacao has this type of effect on the brain, they do know that it increases occipital beta EEG readings, which corresponds directly with attention and alertness.
In the recent years, this humble vegetable has created a lot of noise because of its cancer-fighting antioxidants. Out of all the cruciferous vegetables, broccoli is one of the best sources of antioxidants like carotenoids lutein, zeaxanthin and beta-carotene. The best way to have broccoli is to steam it. Remember that some antioxidants like Vitamin C are completely destroyed by heat while others like beta-carotene become more potent on cooking the vegetable.
There’s no doubt that dark chocolate is trending in today’s marketplace, and sales don’t seem to be slowing down anytime soon. Over the last few years, the chocolate industry has seen a move to premium and certified organic dark chocolate, specifically products that are single-origin; have high cacao content’ use natural sweeteners, such as agave, stevia, yacon or coconut sugar; as well as increased sustainable sourcing and origin labeling. As science shows more and more benefits of dark chocolate, its popularity will only continue to grow.
Tension – Although some people reach for a sugary treat to increase energy, sugar may actually zap energy and increase tension. In a small study published in the Journal of Personality and Social Psychology, 18 people rated their tiredness, energy, and tension after eating a candy bar or walking briskly for ten minutes. The group that walked reported higher levels of energy and lower levels of tension. The group that ate a sugary snack reported higher levels of tension than the walkers. The snack group also had a pattern of increased energy after one hour of eating, but two hours later, reported decreased energy and increased tiredness.
When you consume refined sugar, your sweet taste receptors signal the brain’s reward system in a way that is much more potent than consuming a piece of fruit—your brain lights up like a pinball machine due to the intense release of dopamine. Unfortunately, those sweet taste receptors don’t signal you to stop eating when you’ve had too much sugar. In fact, the more sugar you eat, the more you crave, creating a vicious cycle of sugar dependence. On the other hand, if you eat loads of the other white crystal (salt), your salt taste receptors "flip" and provide you with an aversion signal. In other words, if you consume too much salt in a meal, your body has a built-in safety mechanism causing you to crave less salt later in the day. Your body is extremely smart when it comes to regulating the intake of essential minerals, especially one as important as salt.

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.
