Abstract 
 
 Background: The prevalence of type 2 diabetes (T2D) is increasing around the world. Eggs are a major source of cholesterol, which has been associated with elevated blood glucose and an increased risk of T2D. However, there are limited and conflicting data from prospective population studies on the association between egg consumption and risk of T2D. 
 
 Objective: We investigated the association between egg consumption and risk of incident T2D in middle-aged and older men from eastern Finland. 
 
 Design: The study included 2332 men aged 42–60 y in 1984–1989 at the baseline examinations of the prospective, population-based Kuopio Ischemic Heart Disease Risk Factor Study. Dietary intakes were assessed with 4-d food records at baseline. Incident T2D was assessed by self-administered questionnaires; by fasting and 2-h oral-glucose-tolerance-test blood glucose measurement at re-examination rounds 4, 11, and 20 y after baseline; and by record linkage to a hospital discharge registry and reimbursement register of diabetes medication expenses. Cox proportional hazards regression analyses were used to estimate associations with the risk of incident T2D. Associations with the metabolic risk markers at baseline and at the 4-y examinations were analyzed by ANCOVA. 
 
 Results: During an average follow-up of 19.3 y, 432 men developed T2D. After adjustment for potential confounders, those in the highest vs. the lowest egg intake quartile had a 38% (95% CI: 18%, 53%; P-trend across quartiles <0.001) lower risk of incident T2D. Analyses with metabolic risk markers also suggested an inverse association with fasting plasma glucose and serum C-reactive protein but not with serum insulin. The associations between cholesterol intake and risk of T2D, plasma glucose, serum insulin, and C-reactive protein were mainly nonsignificant, especially after accounting for egg consumption. 
 
 Conclusion: Higher egg intake was associated with a lower risk of T2D in this cohort of middle-aged and older men. ||||| Frequent sauna bathing can reduce the risk of dementia, according to a recent study carried out at the University of Eastern Finland. In a 20-year follow-up, men taking a sauna 4-7 times a week were 66% less likely to be diagnosed with dementia than those taking a sauna once a week. The association between sauna bathing and dementia risk has not been previously investigated. 
 
 The effects of sauna bathing on the risk of Alzheimer's disease and other forms of dementia were studied in the Kuopio Ischaemic Heart Disease Risk Factor Study (KIHD), involving more than 2,000 middle-aged men living in the eastern part of Finland. Based on their sauna-bathing habits, the study participants were divided into three groups: those taking a sauna once a week, those taking a sauna 2-3 times a week, and those taking a sauna 4-7 times a week. 
 
 The more frequently saunas were taken, the lower was the risk of dementia. Among those taking a sauna 4-7 times a week, the risk of any form of dementia was 66% lower and the risk of Alzheimer's disease 65% lower than among those taking a sauna just once a week. The findings were published recently in the Age and Ageing journal. 
 
 Previous results from the KIHD study have shown that frequent sauna bathing also significantly reduces the risk of sudden cardiac death, the risk of death due to coronary artery disease and other cardiac events, as well as overall mortality. According to Professor Jari Laukkanen, the study leader, sauna bathing may protect both the heart and memory to some extent via similar, still poorly known mechanisms. "However, it is known that cardiovascular health affects the brain as well. The sense of well-being and relaxation experienced during sauna bathing may also play a role."
– Here's one good reason to sweat it out in the sauna on your next visit to the gym: It could reduce your risk of dementia. In the first study of its kind, Finnish researchers found that men who used a sauna four to seven times a week were 66% less likely to be diagnosed with dementia. Writing in the journal Age and Ageing, researchers said more study is needed to figure out the link between sauna bathing and memory. "It is known that cardiovascular health affects the brain as well," says lead author Jari Laukkanen, per Science Daily. "The sense of well-being and relaxation experienced during sauna bathing may also play a role." Researchers at the University of Eastern Finland divided 2,300 men between 42 and 60 years old into three groups: those who used a sauna once a week, two to three times a week, and four to seven times a week. Not only were the frequent users 66% less likely to be troubled with any form of dementia, they were 65% less likely to be diagnosed with Alzheimer's disease. Average temperatures in the sauna hovered around 174 degrees Fahrenheit. The men were followed for more than 20 years as part of the Kuopio Ischaemic Heart Disease Risk Factor Study, which has produced valuable research over the years, including last year's findings that higher egg consumption lowered the risk of type 2 diabetes. (Previous research from the same long-term study suggests the sauna can help you live longer.)
