New insights on why improvements to Chesapeake Bay remain a challenge

A new study on Chesapeake Bay water quality found that pollution thresholds affect reduction efforts, and larger reductions may be needed to induce complete reversal of eutrophication-induced hypoxia. The research revealed that the system responds only until a certain threshold is crossed, then it takes twice the effort to make a change.

Blood-based metabolic signature outperforms standard method for predicting diet, disease risk

A new study found that a machine learning-based blood test can accurately predict an individual's entire diet over 19 food groups, outperforming traditional methods. The test, which uses molecular profiling, also identifies who is more likely to develop diabetes and cardiovascular disease based on each food group.

Finding current toilet technology flushes profits, WVU researcher takes aim at turning yellow into green by recycling urine

A WVU engineer has developed a technology that can treat urine on site rather than at a centralized wastewater treatment facility, allowing for the recovery of nitrogen as a valuable fertilizer. The approach enables quick treatment and promotes the reduction of nutrient discharge into lakes and rivers.

Adoption of front-of-pack nutrition warnings can help decrease obesity, cardiovascular disease, type-2 diabetes and some cancers in the Americas

A recent study led by the University of Nevada, Reno and the Pan American Health Organization suggests that the adoption of front-of-pack nutrition labeling can help reduce poor-nutrition related non-communicable diseases in the region. Improved FOPNL systems have been associated with improved diet quality and reduced risk of NCDs.

Are Americans eating enough whole grains? It depends on who you ask

A new study finds that different definitions of whole-grain foods yield varying results on American consumers' intake, highlighting the need for a standardized consensus. While overall consumption has increased, it remains below recommended levels, with discrepancies among racial/ethnic groups and across institutions.

Consuming a high sodium, low potassium diet can increase the risk of cognitive decline

A new study published in the KeAi journal Global Transitions found that consuming a high sodium, low potassium diet can increase the risk of cognitive decline in elderly people. Participants who replaced 1000mg/day of sodium with an equal intake of potassium showed an average increase of ~1 point on their cognitive test score.
