Whole fruits are an abundant source of fiber, antioxidants, and other phytochemicals that may help to promote overall health. Qi Sun, from Harvard School of Public Health (Massachusetts, USA), and colleagues analyzed data collected on 66,105 women enrolled in the Nurses' Health Study, 85,104 from the Nurses' Health Study II, and 36,173 men from the Health Professionals Follow-up Study. Every 4 years, subjects were surveyed as to how often they ate various foods and on their diabetes status, among other measures. While all participants were free of major chronic diseases at baseline, 6.5% developed diabetes during follow-up. Adjusted hazard ratios pooled across the three studies for diabetes risk per three whole fruit servings per week were: 0.74 for blueberries; 0.88 for grapes and raisins; 0.93 for apples and pears. Cantaloupe elevated the diabetes risk by 10%; whereas the risk was neutral for peaches, plums, apricots, prunes, oranges, and strawberries. Interestingly, the researchers found that the same amount of fruit juice correlated with a significant 8% elevated risk of developing diabetes. The study authors conclude that: “Greater consumption of specific whole fruits, particularly blueberries, grapes, and apples, is significantly associated with a lower risk of type 2 diabetes, whereas greater consumption of fruit juice is associated with a higher risk.”

Tip #192 - Stay Connected
Researchers from the University of Chicago (Illinois, USA) report that social isolation may be detrimental to both mental and physical health. The team analyzed data from the National Social Life, Health, and Aging Project, a nationwide US study involving 3,000 men and women, ages 57 to 85 years. They arrived at three key findings regarding the relationships between health and different types of isolation:
• The researchers found that the most socially connected older adults are three times as likely to report very good or excellent health compared to those who are least connected, regardless of whether they feel isolated.
• The team found that older adults who feel least isolated are five times as likely to report very good or excellent health as those who feel most isolated, regardless of their actual level of social connectedness.
• They determined that social disconnectedness is not related to mental health unless it brings feelings of loneliness and isolation.
Separately, Rush University Medical Center (Illinois, USA) researchers studied 906 older men and women, testing their motor functions (including grip, pinch strength, balance, and walking) and surveying their social activity, for a period of 5 years. Those study participants with less social activity were found to have a more rapid rate of motor function decline. Specifically, the team found that every one-point decrease in social activity corresponded to an increase in functional aging of 5 years, translating to a 40% higher risk of death and 65% higher risk of disability.
