Highlights of the February Journal of the American Dietetic Association

... fruits like applesauce or fruit cocktail; soy and legumes (beans); high-fiber cereals like shredded wheat or all bran; high-fat grain-based dishes like pizza and high-fat salty snacks. Higher-fiber fruits and vegetables were consumed in quantities too small to contribute to total average fiber intake. "Alt...

Plant hemoglobins: Oxygen handlers critical for nitrogen fixation

...in the fixation of nitrogen in the root nodules of legumes through a process that is conceptually not unlike that undertaken by mammalian hemoglobins in facilitating oxygen transport and exchange in the blood. The most conspicuous plant hemoglobins are the symbiotic hemoglobins of legumes; these hemoglobins ...

Study finds no association between diet and pancreatic cancer among men and women

... consumption of fruits, vegetables, fish, poultry, legumes and whole grains. During the span of the study 366 cases of pancreatic cancer were documented (185 men and 181 women). The researchers found no strong association between the two dietary patterns and the risk of pancreatic cancer among the study part...

Joslin Diabetes Center announces new nutrition guidelines

...ken or turkey, nonfat or lowfat dairy products and legumes such as kidney beans, black beans, chick peas and lentils. Weight Loss Guidelines: A modest weight loss of one pound every one to two weeks is advised. Reducing daily calories should be by 250 to 500 calories; total daily calories should not be le...

Nitrogen fertilization of soil puts rare plant species at risk, nationwide study determines

... takes over due to fertilization. Over half of the legumes (species that form a symbiotic relationship with bacteria to fix nitrogen from the atmosphere and so do not rely on soil nitrogen) are lost because the benefits associated with nitrogen-fixing no longer outweigh the costs. These species include plan...

Plants, too, have ways to manage freeloaders

...bacteria, such as the classic relationship between legumes and nitrogen-fixing bacteria. As legumes such as the lupine sprout, they send out roots that encounter nitrogen-fixing bacteria in the soil. ...

Hold your breath; Plants may absorb less carbon dioxide than we thought

...er any advantage. Plants in plots with and without legumes were statistically indistinguishable in their ability to increase their growth in response to elevated CO2 levels. Nor did it matter whether the plots contained one, four, nine or 16 species of plants. "Different kinds of species respond differently...

A new plant-bacterial symbiotic mechanism promising for crop applications

...fa, clover, sainfoin). In addition, cultivation of legumes living in symbiotic association with bacteria can contribute to vegetation regeneration schemes on soils depleted in nitrogen owing to overexploitation, erosion or desertification. The plant cover thus formed can help achieve ecological restoration, ...

Researchers probe risks, benefits of folic acid fortification

...naturally in foods such as leafy green vegetables, legumes and citrus fruits. The body's response to folic acid appears to be complex, says Mason. While fortification of the food supply is clearly beneficial for women of child-bearing age and their offspring, it is possible that it may, coincidentally, be li...

Alternative farming cleans up water

...a, buckwheat, and rye with nutrients supplied from legumes and either fresh or composted manure sources. The study found that alternative cropping systems reduced the amount of water lost in tile drainage by 41 percent compared to a conventional corn-soybean rotation. Alternative farming practices also reduc...
