health briefs Eat Produce to Lower
Stress and Heart Disease People needing a push to eat more fruits and vegetables might be motivated by two new studies from Australia’s Edith Cowan University. Studying data from 8,600 Australians between the ages of 25 and 91, researchers found people that ate at least 470 grams (about two cups) of fruits and vegetables per day had 10 percent lower stress levels compared to those that ate less than half that amount. “Vegetables and fruits contain
important nutrients such as vitamins, minerals, flavonoids and
carotenoids that can reduce inflammation and oxidative stress, and therefore improve mental well-being,” says lead author Simone Radavelli-Bagatini.
In a second study based on 23 years of data on 50,000 Danes, researchers found that those that consumed one cup each day of the most nitrate-rich vegetables like leafy greens and beets had about a 2.5 mmHg lower systolic blood pressure and a 12 to 26 percent lower risk of peripheral artery disease, heart attacks, strokes and heart failure. Eating more than one cup daily didn’t increase the benefits, they found, and blending greens into smoothies (but not pulp-destroying juicing) is a good option for increasing intake.
Microbiome Linked to Risk
of Death from Disease Certain gut microbiota can predict possible causes of mortality, reports a new study from Finland’s University of Turku. Researchers collected stool samples from 7,055 Finnish adults around
50 years old and followed them for 15 years. They found that greater numbers of bacteria from the Enterobacteria family increase the risk of death from cancer, respiratory disorders and gastrointestinal disease. “Many bacterial strains that are known to be harmful were among the Enterobacteria predicting mortality, and our lifestyle choices can have an impact on their amount in the gut,” says study co-author Teemu Niiranen.

Live Longer Omega-3 fatty acids have previously been linked to better heart, brain, eye and joint health, and a new large- scale analysis published in Nature Communications suggests that omega- 3s from oily fish may also extend lifespan. Researchers reviewed pooled data from 17 studies of 42,466 people that were followed an average of 16 years. Those that had the highest amount of fish- based omega-3s in their
blood—at the 90th percentile—had a 13 percent lower risk for death than people with omega-3 levels in the 10th percentile. The risk of dying from cardiovascular disease was 15 percent lower and from cancer 11 percent lower. The blood levels of alpha-linolenic acid omega-3s obtained from plant-based sources like nuts and flaxseed did not show a conclusive link to lower mortality.
