"Investigadores da estação televisiva NBC 5 observaram que a água usada para chá e café é água que provém da torneira e não de uma garrafa, em pleno voo.

De acordo com uma amostra da Agência de Proteção Ambiental dos EUA de 2004, resultante de testes a 158 aviões, 13% continham bactérias indicadoras de contaminação (coliformes). Em 2 dos aviões encontraram E.coli (Escherichia coli) perigosa na água. Esta bactéria, quando em grandes quantidades, pode causar infeção intestinal e urinária.

Num estudo adicional da EPA, descobriu-se também que um 1 cada 8 aviões falha nos padrões relativos à segurança da água. Isto, por si só, indica que não deve mesmo pedir chá ou café num avião."

"Amazon.com Review

Get ready to give up that morning latte and kiss cola goodbye. Here comes Caffeine Blues, by Stephen Cherniske, M.S., the first book to expose the dark side of America's No. 1 drug: caffeine. If you are one of the nearly 80 percent of Americans hooked on caffeine--a natural component of coffee, tea, and chocolate and a common ingredient in drugs, soda, candy, and other products--this book will be a wake-up call.

In Caffeine Blues, Cherniske, a nutritional biochemist with more than 25 years of academic research and clinical experience and author of the bestseller The DHEA Breakthrough, reveals the truth about caffeine and explains how to kick the habit forever. Cherniske discusses how caffeine affects the body and brain and why it can increase your risk of dozens of health disorders ranging from osteoporosis, diabetes, and PMS to hypertension and heartburn. After spending 300 pages documenting all of caffeine's evils, Cherniske finally offers a decaffeinated life line: "Off the Bean and on to Vitality," a step-by-step, clinically proven program to help readers kick the habit and boost energy levels naturally. --Ellen Albertson"

Sono e problemas de coração?

"Dr Sasaki concluded: “Our results support the hypothesis that sleep deterioration may lead to cardiovascular disease. Poor sleep in patients with ischaemic heart disease may be characterised by shorter sleep and brief moments of waking up.”

He added: “Difficulty maintaining sleep reflects an increase in sleep fragmentation, which refers to brief moments of waking up and causes overactivity of the sympathetic nervous system and adrenocortical axis.”

Previous research, published by the University of California San Francisco last year, suggests people who do not sleep all the way through the night are at a 29 per cent increased risk of developing an irregular heartbeat."

Cuidado com os "substitutos" da fruta

Coma-se fruta (5 por dia, ou 10 conforme os estudos) não "substitutos" de fruta, porque ou contêm menos fruta do que se esperaria, ou contêm açúcar em excesso:

375g de fruta, 400g (OMS) ou 800g por dia?

https://www.theguardian.com/science/2017/aug/29/life-saving-fruit-and-vegetable-diet-need-only-be-three-portions-study

Citando:
"Wolfing down a mountain of fruit and vegetables every day offers no more benefit in staving off death than eating just three to four portions, researchers have found, adding that the findings could have important ramifications for those on low incomes.

The World Health Organisation currently recommends individuals eat at least 400g of fruit, vegetables and legumes – plants such as peas and beans – each day, although recent studies have suggested as much as 800g should be consumed to reduce the risk of stroke, heart disease and premature death."

PS.
Artigo sobre o "10 a day" (em vez do conselho mais comum de "5 per day"):

"Five portions of fruit and veg a day is good for you, but 10 is much better and could prevent up to 7.8 million premature deaths worldwide every year, say scientists. "

Tinnitus estudado

"The precuneus is connected to the dorsal attention network – an area responsive to attention demanding tasks, and the default mode network, the area which is activated during less mentally strenuous activity.

“When the default mode network is on, the dorsal attention network is off, and vice versa. We found that the precuneus in tinnitus patients seems to be playing a role in that relationship,” said Sara Schmidt, a graduate student in the university’s neuroscience program.

For those suffering from chronic tinnitus, the precuneus is more closely connected to the dorsal attention network, than the default-mode network, MRI scans showed.

The research suggests that tinnitus sufferers are “not truly at rest, even when resting”, said Fatima Husain, lead researcher and on the study and a professor at the university."
