In this round-up, we bring you the latest research findings on health and nutrition, including new findings on how consuming tocotrienol-enriched oat could improve fasting blood glucose and lutein, zeaxanthin’s benefits for dry eyes.

Diabetes, heart disease risk among women correlated to pregnancy status

Pregnancy is a “stress test” which shows women who are at a greater risk for chronic diseases, according to an expert researcher studying women health.

Professor Zhang Cuilin, chair professor at the NUS Yong Loo Lin School of Medicine, pointed out the above during her talk at the Founders Longevity Forum held in Singapore between February 27 and 28.

She pointed out how the age of menarche, menstrual cycle regularity, and pregnancy status, are linked to the onset of chronic diseases, based on existing research findings.

Eating tocotrienol-enriched oat improves blood glucose, blood pressure - RCT

Eating tocotrienol-enriched oat can help significantly improve fasting blood glucose and blood pressure in people suffering from metabolic syndrome, say findings from a 12-week clinical trial conducted in Malaysia.

There was also a significant increase in the “good cholesterol” high density lipoprotein-cholesterol (HDL-C).

Findings of the study were published in the journal Food & Function.

Lutein-zeaxanthin supplementation in high screen time users found to improve dry eyes, macular function – RCT

Six months of lutein and zeaxanthin supplementation in people with high usage of electronic screens has positive effects on dry eyes and macular function.

Findings of the study were published in Frontiers in Nutrition.

Seventy participants aged 18 to 65, who spent at least six hours per day viewing an electronic screen at a distance of one metre or less, took part in the trial.

‘Beyond normal’: Personalised indole supplementation could help manage anxiety, say researchers

Personalised indole supplementation may offer a natural way to manage anxiety and its related conditions, according to researchers in Singapore.

Indoles are found in vegetables such as cabbage, broccoli, and Brussels sprouts. It may help regulate anxiety-related behaviours by modulating neurotransmitter activity and reducing stress-related inflammation.

Researchers from Duke-NUS and the National Neuroscience Institute of Singapore said they planned to develop an indole-based supplement to stimulate gut bacteria and potentially reduce anxiety.

Vitamin E potentially beneficial for managing male infertility – RCT

Vitamin E supplementation have shown positive effects on the sperm quality of varicocelectomy patients.

Varicocelectomy is a procedure used to correct varicocele, a condition characterised by abnormal dilation and elongation of veins within the scrotum. Varicocele is also a cause of male infertility.

Writing in Trials, a group of researchers from Iran reported that while varicocelectomy alone significantly improve sperm health, vitamin E supplementation could enhance the benefits of this procedure.
