Escovar os dentes bem?

Citando:
"There is some evidence that small-headed electric toothbrushes tend to be a bit better than manual brushes – but make sure you still use them in a systematic way.

Brushing your teeth fights gum disease; fluoride toothpaste stops the decay. Spit the toothpaste out but don’t rinse out. Mouthwash by itself is not going to do the job that brushing with toothpaste does. If you do want to use mouthwash, again spit rather than rinse.

Ask your dentist or hygienist about flossing. For most people, good brushing will be enough. Others may be more susceptible to gum disease and have to do more, such as using interdental brushes (for gaps between teeth) and floss (where your teeth have tight contact)."

And for sperm, that is certainly the case, according to a new scientific study.

Researchers have discovered that the sperm of infertile men is every bit as healthy as fertile men while it is still in the testicles."

"'Encouraging'

Mild cognitive impairment (MCI) can make people forgetful, affect their memory and cause problems with language, attention and locating objects in spaces - but the changes can be subtle.

It is not serious enough to be defined as dementia.

The participants in the study were asked how often they ate six different types of mushrooms: oyster, shiitake, white button, dried, golden and tinned.

Mushroom eaters performed better in brain tests and were found to have faster processing speed - and this was particularly noticeable in those who ate more than two portions a week, or more than 300g (10.5oz).

"This correlation is surprising and encouraging," said assistant professor Lei Feng, the lead study author, from the university's department of psychological medicine."

"Segundo novas descobertas, uma dieta com pouca proteína e muito hidrato de carbono dispara várias respostas fisiológicas que nos protegem de várias doenças ligadas ao envelhecimento, incluindo cancro, doenças cardiovasculares e Alzheimer. E é possível que a proporção de Okinawa atinja o melhor equilíbrio para alcançar esses efeitos.

(...)

Em vez de sofrer uma morte prolongada, os centenários de Okinawa parecem atrasar muitos dos efeitos normais do envelhecimento, com quase dois terços das pessoas a viver de maneira independente até os 97 anos.

A impressionante longevidade saudável ficou evidente ao avaliar várias doenças relacionadas à idade. O típico centenário de Okinawa parece estar livre dos sinais típicos de doenças cardiovasculares, sem construir as placas calcificadas em redor das artérias que podem levar à falência do coração. Os residentes mais velhos também apresentam taxas mais baixas de cancro, diabetes e demência do que outras populações.

A sorte na questão genética pode ser um fator importante. (...). Estudos preliminares sugerem que isto pode incluir uma prevalência reduzida de uma variável genética– APOE4 – que parece aumentar o risco de doenças cardíacas e Alzheimer.

Eles também podem ter uma tendência maior de carregar uma variável protetora do gene FOXO3, envolvido na regulação do metabolismo e do crescimento celular. Isto resulta numa estatura mais baixa, mas também parece reduzir o risco de várias doenças relacionadas à idade, incluindo cancro."

"Some people have a gene linked with happy marriages, scientists find

'This study shows that how we feel in our close relationships is influenced by more than just our shared experiences with our partners'"

(...)

"People with this gene variant – known as the GG genotype – are already known to show greater empathy, sociability and emotional stability.

Given the kind of characteristics that might contribute to a happy and successful marriage, it is perhaps unsurprising that this was the stretch of DNA found frequently in content spouses."
