Honey with its long history in tradition, now has proof confirming its claims. Honeybees transform a plant product, nectar, without removing the good stuff. Phenolic content is what makes honey is so adaptable to so many therapies. Thanks to New Zealand beekeepers who've worked hard to make Manuka Honey acceptable in surgical settings. The fact is, there are a lot of monofloral honeys worldwide that have equal or superior health benefits. The march continues...
Honey as a
Source of Dietary Antioxidants: Structures, Bioavailability and Evidence of
Protective Effects Against Human Chronic Diseases
Curr MedChem 2013, vol 20, issue 5, pages 621-638
In the long
human tradition honey has been used not only as a nutrient but also as a
medicine. Its composition is rather variable and depends on the floral source
and on external factors, such as seasonal, environmental conditions and
processing.
In this
review, specific attention is focused on absorption, metabolism, and beneficial
biological activities of honey compounds in human. Honey is a supersaturated
solution of sugars, mainly composed of fructose (38%) and glucose (31%),
containing also minerals, proteins, free amino acids, enzymes, vitamins and
polyphenols. Among polyphenols, flavonoids are the most abundant and are
closely related to its biological functions. Honey positively affects risk
factors for cardiovascular diseases by inhibiting inflammation, improving
endothelial function, as well as the plasma lipid profile, and increasing
low-density lipoprotein resistance to oxidation. Honey also displays an
important antitumoral capacity, where polyphenols again are considered
responsible for its complementary and overlapping mechanisms of chemopreventive
activity in multistage carcinogenesis, by inhibiting mutagenesis or inducing
apoptosis.
Moreover,
honey positively modulates the glycemic response by reducing blood glucose,
serum fructosamine or glycosylated hemoglobin concentrations and exerts
antibacterial properties caused by its consistent amount of hydrogen peroxide
and non-peroxide factors as flavonoids, methylglyoxal and defensin-1 peptide.
In
conclusion, the evidence of the biological actions of honey can be ascribed to
its polyphenolic contents which, in turn, are usually associated to its
antioxidant and anti-inflammatory actions, as well as to its cardiovascular,
antiproliferative and antimicrobial benefits.
