Personalized nutrition more effective than general diet advice, study finds
King's College London, May 8, 2024 (Medical Xpress)

Personalized nutrition approaches can improve several key health metrics, including lower weight, lower cholesterol, better mood, improved gut health, lower heart disease risk, and better metabolic health.
Improvements for those following personalized guidance were also greater in some areas than for those following current, generalized government advice.
In this study, researchers wanted to see if a personalized diet plan, tailored to an individual's biology, lifestyle, and health history, would have a greater impact than generic nutrition advice such as avoiding red meat. 347 Americans took part in the study, with researchers comparing the effects of following an 18-week personalized program to generic US government-issued nutrition advice. While both groups improved their health overall, participants on the personalized diet plan lost more weight than the control group and lowered their triglyceride levels more—decreasing their risk of heart disease.
Participants following the personalized diet plan were also twice as likely to report improved mood, twice as likely to feel less hungry, and more than four times more likely to report better sleep quality and energy levels compared with the control group.
 
Vitamin K1 may improve insulin sensitivity and blood sugar levels for pre-diabetics
Ahvaz Jundishapur University (Iran), May 6, 2024 (Nutraingredients)
Supplements containing vitamin K1 (phylloquinone) may improve glycemic status and insulin sensitivity for premenopausal and pre-diabetic women, says a new study.
“To the best of our knowledge, the present study is the first one that investigated the effects of vitamin K1 supplementation on the glycemic status and insulin sensitivity via different forms of [osteocalcin] in pre-diabetic women,” wrote the researchers in the European Journal of Clinical Nutrition .
Osteocalcin (cOC) is a vitamin K-dependent protein. Without adequate vitamin K, the osteocalcin remains inactive (uncarboxylated osteocalcin, ucOC), and thus not effective.
The new study used phylloquinone at a daily dose of 1,000 micrograms for four weeks. Eighty-two pre-diabetic and pre-menopausal women participated in the study and were randomly assigned to either the vitamin K1 group or placebo.
Results showed that cOC levels increased as a result of K1 supplementation, while ucOC levels decreased, compared with placebo.
In addition, results of the two hour post-oral glucose tolerance test showed improvements in both glucose and insulin levels in the K1 group, compared with placebo. Data from the insulin sensitivity index (ISI) showed increases in the K1 group, they added.
  
Frequent salting of food increases the risk of stomach cancer

Medical University of Vienna (Austria), May 8, 2024 (Eurekalert)


In Asian countries, where high-salt foods are popular, the link between high salt consumption and stomach cancer has already been proven. A long-term study by MedUni Vienna has now shown for the first time that this risk is also reflected in the cancer statistics in Europe. As the analysis recently published in the specialist journal Gastric Cancer shows, people who frequently add salt to their food are around 40 per cent more likely to develop stomach cancer than those who
