Estimating calorie content not clear-cut for all
We make food decisions several times a day – from what time we eat to how much – but a new study has found we are not very good at judging the energy-density of what we consume.

Food insecurity in young adults raises risk for diabetes, high blood pressure, asthma
A paradox of food insecurity in wealthy countries is its association with excess weight. Now, a study finds that young adults in the United States who are food insecure not only are slightly more likely to be obese, they are significantly more likely to suffer from disorders associated with high body mass index, as well as obstructive airway diseases like asthma.

High levels of fructose in the diet inhibit the liver's ability to properly metabolize fat. This effect is specific to fructose. Indeed, equally high levels of glucose in the diet actually improve the fat-burning function of the liver.
Read moreGene responsible for lutein esterification in bread wheat identified
Researchers have identified and confirmed the gene responsible for lutein esterification in bread wheat. The activity of this gene controls the timing of esterification in grain, which is related to storage and nutritional qualities of bread wheat and other grains.

Prebiotics are only able to help stabilize the intestinal flora of horses to a limited degree. Before they can reach the intestines, commercially available supplements partially break down in the animals' stomachs, which can lead to inflammation of the stomach lining.
Read moreNo need to cut down red and processed meat, controversial findings suggest
Contrary to previous advice, five new systematic reviews suggest that most people can continue to eat red and processed meat as they do now. The major studies have found cutting back has little impact on health.
Pineapple genome sequences hint at plant domestication in a single step
An international team published their analysis of the genome of the red pineapple, a plant grown for fiber production and as an ornamental.
Read moreORNL scientists shed light on microbial 'dark matter' with new approach
Scientists have demonstrated a way to isolate and grow targeted bacteria using genomic data, making strides toward resolving the grand challenge of uncultivated microbial 'dark matter' in which the vast majority of microorganisms remain unstudied in the laboratory.

Contrary to previous advice, five new systematic reviews suggest that most people can continue to eat red and processed meat as they do now. The major studies have found cutting back has little impact on health.
Cooking food alters the microbiome
Scientists have shown for the first time that cooking food fundamentally alters the microbiomes of both mice and humans, a finding with implications both for optimizing our microbial health and for understanding how cooking may have altered the evolution of the our microbiomes during human prehistory.
