Most worker bees visit thousands of flowers every day in their search for nectar to feed their queen's brood.

#Bees get a buzz from flower nectar containing caffeineyou may need a cup of coffee to kick start the day
but it seems honeybees also get their buzz from drinking flower nectar containing caffeine. Publishing in Science researchers have shown that caffeine improves a honeybee's memory
which occurs naturally in the nectar of coffee and citrus flowers were three times more likely to remember a flower's scent than those feeding on just sugar.
In turn bees that have fed on caffeine-laced nectar are laden with coffee pollen and these bees search for other coffee plants to find more nectar leading to better pollination.
So caffeine in nectar is likely to improve the bee's foraging prowess while providing the plant with a more faithful pollinator.
In the study researchers found that the nectar of Citrus and Coffea species often contained low doses of caffeine.
They included'robusta'coffee species mainly used to produce freeze-dried coffee and'arabica'used for espresso and filter coffee.
so we were surprised to find it in the nectar. However it occurs at a dose that's too low for the bees to taste
Typically the nectar in the flower of a coffee plant contains almost as much caffeine as a cup of instant coffee.
Phytase breaks down phytic acid and helps pigs digest more of the nutrient. The phytase enzyme has a hefty price tag for farmers
This novel communication channel reveals how flowers can potentially inform their pollinators about the honest status of their precious nectar and pollen reserves.

Their observation of how patterns of pigmentation on flower petals influence bumblebees'behavior suggests that color veins give clues to the location of the nectar.

because they can be useful nectar guides particularly when they also increase flower visibility. But it appears that the color contrast of a flower with its background has a greater influence on bee preference.

and the nutrients in such forms are difficult for plants to use. The active labile fraction however is a modest but important part of the organic matter.

#No clear evidence more gluten in new wheat is responsible for increase in celiac diseaseno clear evidence exists to support the idea that celiac disease is increasing in prevalence
because farmers are growing strains of wheat that contain more gluten. That's the conclusion of an article in the ACS'Journal of Agricultural and Food Chemistry.
Also known as gluten intolerance celiac disease occurs when gluten a protein in wheat barley and rye damages the lining of the small intestine causing a variety of symptoms.
Nobody knows why the disease is increasing. One leading explanation suggests that it results from wheat breeding that led to production of wheat varieties containing higher levels of gluten.
Kasarda's Perspective article examined the scientific evidence for that hypothesis and found that gluten levels in various varieties have changed little on average since the 1920s.
Overall gluten consumption however has increased due to other factors. One involves increased consumption of a food additive termed vital gluten
which has tripled since 1977. Vital gluten is made a food additive from wheat flour and it is added to various food products to improve their characteristics such as texture.
Overall consumption of wheat flour also has increased so that people in 2000 consumed 2. 9 pounds more gluten annually than in 1970 nearly a 25 percent increase.
