Thanks to Ron's Healthy Food Link. Honey is a part of my daily diet but then again I don't compete.
Health Benefits
In addition to its reputation as Nature's nutritive sweetener, research also indicates that honey's unique composition makes it useful as an antimicrobial agent and antioxidant.
Raw Honey - An Anti-Bacterial, Anti-Viral, Anti-Fungal Substance
The health benefits of honey - like all foods - depend on the quality of the honey. But in this case, the situation is even more extreme, because the pollen that collects on the bees' legs as they move from plant to plant is only as healthful and as diverse as those plants. In addition, the processing of honey often removes many of the phytonutrients found in raw honey as it exists in the hive. Raw honey, for example, contains small amounts of the same resins found in propolis. Propolis, sometimes called "bee glue," is actually a complex mixture of resins and other substances that honeybees use to seal the hive and make it safe from bacteria and other micro-organisms. Honeybees make propolis by combining plant resins with their own secretions. However, substances like road tar have also been found in propolis. Bee keepers sometimes use special screens around the inside of the hive boxes to trap propolis, since bees will spread this substance around the honeycomb and seal cracks with the anti-bacterial, anti-viral, and anti-fungal resins. The resins found in propolis only represent a small part of the phytonutrients found in propolis and honey, however. Other phytonutrients found both in honey and propolis have been shown to posssess cancer-preventing and anti-tumor properties. These substances include caffeic acid methyl caffeate, phenylethyl caffeate, and phenylethyl dimethylcaffeate. Researchers have discovered that these substances prevent colon cancer in animals by shutting down activity of two enzymes, phosphatidylinositol-specific phospholipase C and lipoxygenase. When raw honey is extensively processed and heated, the benefits of these phytonutrients are largely eliminated.
Improve Athletic Performance and Heal Wounds with Honey?
Primarily honey has been used as an energy source, but recent research has examined the use of honey as an ergogenic aid (a food or ingredient that helps an athlete's performance) and wound healing agent, both of which were once considered merely age-old anecdotes.
In the time of the ancient Olympics, athletes were reported to eat special foods, such as honey and dried figs, to enhance their sports performance. Recently, however, one group of researchers has investigated the use of honey as an ergogenic aid in athletes. The study involved a group of 39 weight-trained athletes, both male and female. Subjects underwent an intensive weight-lifting workout and then immediately consumed a protein supplement blended with either sugar, maltodextrin or honey as the carbohydrate source. The honey group maintained optimal blood sugar levels throughout the two hours following the workout. In addition, muscle recuperation and glycogen restoration (carbohydrates stored in muscle) was favorable in those individuals consuming the honey-protein combination.
Sustaining favorable blood sugar concentrations after endurance training by ingesting carbohydrates before, during and after training is important for maintaining muscle glycogen stores (glycogen is the form in which sugar is stored in muscle as ready-to-use fuel), so that muscle recuperation is more efficient and the athlete is ready to perform again at their highest level the next day. The best-studied ergogenic aid is carbohydrates because they are necessary for maintaining muscle glycogen stores. For now, honey appears to be just another source of carbohydrates that can help athletes perform at their best, rather than a superior choice over any other carbohydrate.
The wound healing properties of honey may, however, be its most promising medicinal quality. Honey has been used topically as an antiseptic therapeutic agent for the treatment of ulcers, burns and wounds for centuries. One study in India compared the wound healing effects of honey to a conventional treatment (silver sulfadiazene) in 104 first-degree burn patients. After one week of treatment, 91 percent of honey treated burns were infection free compared with only 7 percent receiving the conventional treatment. Finally, a greater percentage of patients' burns were healed more readily in the honey treated group. Another study examined the wound healing benefits of honey applied topically to patients following Caesarean section and hysterectomy. Compared to the group receiving the standard solution of iodine and alcohol, the honey treated group was infection free in fewer days, healed more cleanly and had a reduced hospital stay.
Several mechanisms have been proposed for the wound healing benefits that are observed when honey is applied topically. Because honey is composed mainly of glucose and fructose, two sugars that strongly attract water, honey absorbs water in the wound, drying it out so that the growth of bacteria and fungi is inhibited (these microorganisms thrive in a moist environment). Secondly, raw honey contains an enzyme called glucose oxidase that, when combined with water, produces hydrogen peroxide, a mild antiseptic. In addition to the specific enzymes found in honey, which may help in the healing process, honey also contains antioxidants and flavonoids that may function as antibacterial agents. One antioxidant in particular, pinocembrin, which is unique to honey, is currently being studied for its antibacterial properties. One laboratory study of unpasteurized honey samples indicated the majority had antibacterial action against Staphylococcus aureus, a common bacteria found readily in our environment that can cause infections, especially in open wounds. Other reports indicate honey is effective at inhibiting Escherichia coli and Candida albicans. Darker honeys, specifically honey from buckwheat flowers, sage and tupelo, contain a greater amount of antioxidants than other honeys, and raw, unprocessed honey contains the widest variety of health-supportive substances.
A Spoonful a Day Keeps Free Radicals at Bay
Daily consumption of honey raises blood levels of protective antioxidant compounds in humans, according to research presented at the 227th meeting of the American Chemical Society in Anaheim, CA, March 28, 2004. Biochemist Heidrun Gross and colleagues from the University of California, Davis, gave 25 study participants each about four tablespoons buckwheat honey daily for 29 days in addition to their regular diets, and drew blood samples at given intervals following honey consumption. A direct link was found between the subjects' honey consumption and the level of polyphenolic antioxidants in their blood.
Honey Helpful for Healthy Individuals and Those with High Cholesterol, Type 2 Diabetes
In a series of experiments involving healthy subjects and those with either high cholesterol or type 2 diabetes, honey has proved itself the healthiest sweetener.
For 15 days, 8 healthy subjects, 6 patients with high cholesterol, 5 patients with high cholesterol and high C-reactive protein (a risk factor for cardiovascular disease), and 7 patients with type 2 diabetes were given solutions containing comparable amounts of sugar, artificial honey or natural honey.
In healthy subjects, while sugar and artificial honey had either negative or very small beneficial effects, natural honey reduced total cholesterol 7%, triglycerides 2%, C-reactive protein 7%, homocysteine 6% and blood sugar 6%, and increased HDL (good) cholesterol 2%. (Like C-reactive protein, homocysteine is a significant risk factor for cardiovascular disease.)
In patients with high cholesterol, artificial honey increased LDL (bad) cholesterol, while natural honey decreased total cholesterol 8%, LDL cholesterol 11%, and C-reactive protein 75%.
And in patients with type 2 diabetes, natural honey caused a significantly lower rise in blood sugar than either dextrose or sucrose (refined sugars). So, enjoy a little honey in your morning coffee, lunchtime yogurt or afternoon cup of green tea. Looks like a daily spoonful of honey may help your need for medicine go down.
Although our food ranking system did not qualify honey as a dense source of traditional nutrients, it did emerge as a source of vitamin B2, vitamin B6, iron and manganese.

Fructose has become the 'whipping boy' recently of obesity problems. Now that they have found folks are eating less fat, and still fat, and less carbs, and still fat, one day they will realize it is not just one thing that is the source of all this evil, it is simply overeating.
To wit....Fruit has way less fructose than most think, it's a mix of glucose, sucrose and fructose.
And for those who run with the media on everything, read the following study. Pay particular attention to the conclusion.....
Macronutrient disposal during controlled overfeeding with glucose, fructose, sucrose, or fat in lean and obese women.

BACKGROUND: Previous short-term studies (< or =6 h) showed differences in energy expenditure (EE) and macronutrient oxidation in response to overfeeding with different types of dietary carbohydrate. This finding could have implications for obesity. OBJECTIVE: We used 96-h continuous whole-body calorimetry in 8 lean and 5 obese women to assess metabolic disposal (energy dissipation and glycogen or fat storage) of a controlled excess of dietary energy supplied as different carbohydrate sources or as fat. DESIGN: Five dietary treatments were applied in random order: energy balance (control) and overfeeding by 50% of energy requirements with fat (O(fat)) or predominantly with glucose, fructose, or sucrose (O(cho)). Macronutrient oxidation rates were assessed from nonprotein gaseous exchanges. Net macronutrient balances were calculated as cumulative differences between intake and oxidation. RESULTS: Increased EE in response to overfeeding dissipated 7.9% of the energy excess with a variation in EE of <1.7% across overfeeding treatments (NS). EE during the O(fat) treatment significantly exceeded that during the control treatment in the lean but not in the obese women. There were no significant differences between lean and obese women in macronutrient oxidation or balances, so data were pooled. O(cho) induced glycogen storage on day 1 ( approximately 100 g) but thereafter progressively stimulated carbohydrate oxidation so that balance was reached on days 3 and 4. Fat oxidation was proportionately suppressed. Of the excess carbohydrate, 74% was oxidized; there were no significant differences between the various O(cho) treatments. O(fat) stimulated fat oxidation by 18% and suppressed carbohydrate oxidation. On average, 12% of the excess energy was stored as glycogen and 88% as fat; there was no significant difference between overfeeding treatments. CONCLUSION: There was no significant difference in fat balance during controlled overfeeding with fat, fructose, glucose, or sucrose.
