Researchers put olive and fish oil IV nutrition under the microscope

A systematic review of six randomized trials compared olive-oil-based and fish-oil-containing parenteral nutrition in hospitalized adults, examining infection, inflammation, oxidative stress, liver function, and clinical outcomes. The included studies involved diverse patient groups and lipid formulations, with substantial variation in outcomes and insufficient evidence for a meta-analysis.

Women with type 2 diabetes saw striking changes after 24 weeks of this eating pattern

A 24-week randomized trial found that a lacto-vegetarian diet combined with 14-hour time-restricted eating improved glycemic control, insulin resistance, body weight, and lipid measures in Indian women with type 2 diabetes. The combined, nutritionist-supported intervention was generally well tolerated, but its individual dietary and fasting effects cannot be separated and longer-term studies are needed.

A four-week spice experiment challenges expectations about post-meal benefits

Culinary doses of herbs and spices did not significantly alter postprandial endothelial function, glycemia, or lipemia after four weeks of corresponding spice-containing diets in adults at cardiometabolic risk. The findings suggest that acute spice-related effects may be less apparent with longer-term exposure, although the study may have been underpowered to detect modest benefits.

Drink spiking is not just a nightclub problem, new UK data suggest

A UK-wide analysis of Drinkaware surveys found that suspected drink spiking and needling are widely underreported, with only 7% of affected 2022 respondents reporting the incident to the police. The findings also reveal gaps in public awareness, demographic differences in reported experiences, and psychological and physical effects that some respondents said persisted for decades.

Why keto appears to lower blood pressure for some people but not others

A narrative review finds that ketogenic diets may modestly lower blood pressure through weight loss, reduced visceral fat, improved insulin sensitivity, fluid and electrolyte shifts, and anti-inflammatory effects. However, effects vary across studies, long-term cardiovascular evidence remains limited, and diet quality, hydration, electrolyte balance, and medication monitoring are important.
