Studies on the association between heavy coffee consumption and risk of less frequently diagnosed cancers are scarce. We aimed to quantify the association between filtered, boiled, and total coffee consumption and the risk of bladder, esophageal, kidney, pancreatic, and stomach cancers. We used data from the Norwegian Women and Cancer Study and the Northern Sweden Health and Disease Study. Information on coffee consumption was available for 193,439 participants. We used multivariable Cox proportional hazards models to calculate hazard ratios (HR) with 95% confidence intervals (CI) for the investigated cancer sites by category of total, filtered, and boiled coffee consumption. Heavy filtered coffee consumers (≥ 4 cups/day) had a multivariable adjusted HR of 0.74 of being diagnosed with pancreatic cancer (95% CI 0.57-0.95) when compared with light filtered coffee consumers (≤ 1 cup/day). We did not observe significant associations between total or boiled coffee consumption and any of the investigated cancer sites, neither in the entire study sample nor in analyses stratified by sex. We found an increased risk of bladder cancer among never smokers who were heavy filtered or total coffee consumers, and an increased risk of stomach cancer in never smokers who were heavy boiled coffee consumers. Our data suggest that increased filtered coffee consumption might reduce the risk of pancreatic cancer. We did not find evidence of an association between coffee consumption and the risk of esophageal or kidney cancer. The increased risk of bladder and stomach cancer was confined to never smokers.

Coffee, a complex brew containing hundreds of biologically active compounds, exerts potent effects on long-term human health. Recently, a plethora of studies have been published focusing on health outcomes associated with coffee intake. An inverse association between coffee consumption and all-cause mortality has been seen consistently in large prospective studies. Habitual coffee consumption is also associated with lower risks for cardiovascular (CV) death and a variety of adverse CV outcomes, including coronary heart disease (CHD), congestive heart failure (HF), and stroke; coffee’s effects on arrhythmias and hypertension are neutral. Coffee consumption is associated with improvements in some CV risk factors, including type 2 diabetes (T2D), depression, and obesity. Chronic coffee consumption also appears to protect against some neurodegenerative diseases, and is associated with improved asthma control, and lower risks for liver disease and cancer. Habitual intake of 3 to 4 cups of coffee appears to be safe and is associated with the most robust beneficial effects. However, most of the studies regarding coffee’s health effects are based on observational data, with very few randomized controlled trials. Furthermore, the possible benefits of coffee drinking must be weighed against potential risks, which are generally due to its high caffeine content, including anxiety, insomnia, headaches, tremulousness, and palpitations. Coffee may also increase risk of fracture in women, and when consumed in pregnancy coffee increases risk for low birth weight and preterm labor.

To examine the relationship between regular game-related caffeine consumption on sleep after an evening Super Rugby game.
Twenty elite rugby union players wore a wrist-activity monitor to measure sleep for three days
before, three days after and on the night of an evening Super Rugby game (19:00–21:00). Players ingested caffeine as they
would normally (i.e. before and sometimes during a game) and saliva samples were collected before (17:00) and after
(21:30) the game for caffeine concentration.
Compared to the nights leading up to the game, on the night of the
game, players went to bed 3 h later (23:08 ± 66 min vs 02:11 ± 114 min; p < .001) and had 1:30 hh:mm less sleep (5:54 ±
2:59 vs 8:02 ± 1:24 hh:mm; p < .05) and four players did not sleep after the game. Post-game caffeine saliva
concentrations were greater than pre-game levels in 17 players (Pre-game 0.40 µg/mL vs Post-game 2.77 µg/mL; p < .001).
The increase in caffeine saliva concentrations was moderately associated with an increase in sleep latency (p < .05), a
decrease in sleep efficiency (p < .05), and a trend for a decrease in sleep duration (p = .06) on game night.
Caffeine consumption before a Super Rugby game markedly increases post-game saliva caffeine levels. This may
contribute to the observed 3.5 h delay in time at sleep onset and the 1.5 h reduction in sleep duration on the night of the
game. This study highlights the need for a strategic approach to the use of caffeine within a Super Rugby team
considering the potential effect on post-game sleep.

Intraocular pressure (IOP) reduction by medications, laser, or surgery remains the mainstay of treatment in glaucoma. However, the role of complementary and alternative medicine (CAM) in glaucoma has received great interest from both patients and ophthalmologists. Previous evidence suggests that diet, a major domain of CAM, can influence an individual’s IOP level. Furthermore, certain dietary components have been linked to the incidence and progression of glaucoma. In this review, we aim to provide a summary of the current evidence regarding the role of obesity, certain dietary components, and dietary supplements in glaucoma.
