Citando:
"Owning a dog is associated with a significantly lower risk of cardiovascular disease and death, according to a comprehensive new study published by a team of Swedish researchers on Friday in the journal Scientific Reports.

The scientists followed 3.4 million people over the course of 12 years and found that adults who live alone and owned a dog were 33 percent less likely to die during the study than adults who lived alone without dogs. In addition, the single adults with dogs were 36 percent less likely to die from cardiovascular disease."

Resveratrol (chocolate preto e tinto)?

"Os genes responsáveis pela mitose – o processo de divisão e multiplicação celular - tendem a deixar de funcionar progressivamente, à medida que as células envelhecem. No entanto, a aplicação dos análogos de resveratrol reacendeu este processo nas células."

Apanhar sol atrás de um vidro traz benefícios? E malefícios?

Parece que o benefício da Vitamina D atrás de um vidro não existe (vidros comuns filtram o UV-B) é que continua a existir risco de cancro de pele (em excesso os UV-A fazem igualmente mal):

Citando:
"The sun emits ultraviolet (UV) A, UVB, and UVC rays. The latter is the most damaging, but is filtered by the atmosphere and doesn’t reach the earth’s surface.

Vitamin D is produced by the body when the skin is hit by UVB rays, with 7-dehydrocholesterol being the resulting chemical. But most glass windows block this wavelength meaning you can't reap the health benefits.

A 2010 US study into skin cancer found that people who spend a lot of time driving a car each week are more likely to develop skin cancers on the left side of the body – which is the window side in North American cars.

Data on 1,000 patients showed that 74 per cent of patients with malignant melanoma, an aggressive form of skin cancer, had tumours on their left sides, according to the study by researchers at the St Louis University, the New York Times reported."

Cogumelos ajudam a prevenir envelhecimento?

Citando:
"Here's How Mushrooms Could Help Fight Ageing

The study conducted by researchers at Pennsylvania State University dubbed mushrooms to be the highest known single source of the antioxidants ergothioneine and glutathione, which are both associated with anti-ageing properties."
(...)
"the countries that have more ergothioneine in their diets, countries like France and Italy, also have lower incidences of neurodegenerative diseases, the average amount of the antioxidant seen in the diets in these countries is about 3 milligrams per day, or about five button mushrooms. While people in countries like the United States, which has low amounts of ergothioneine in the diet, have a higher probability of diseases like Parkinson's Disease and Alzheimer's."

Banho todos os dias?

Talvez mas sem ensaboar intensamente e com água não muito quente:
https://www.tribunaonline.com.br/estudo-aponta-que-tomar-banho-todos-os-dias-pode-fazer-mal-a-saude/

Citando:
"Cientistas da Universidade George Washington da Califórnia, nos Estados Unidos, concluíram que tomar banho diariamente faz mal a saúde. Sim, o que para nós brasileiros é um ato de higiene, aos olhos dos cientistas é algo que prejudica a nossa saúde.

Segundo o estudo da Universidade, o banho diário afeta a camada mais externa da epiderme, chamada “camada córnea”. Esta camada mais fragilizada permite que os lipídios e os compostos gordurosos – que ajudam a manter a pele úmida – se dissolvam.

De acordo com o professor assistente de dermatologia da universidade Brandon Michell, o ideal é que o banho seja tomado uma ou duas vezes por semana. Mas, se o indivíduo quiser se banhar, o cientista recomenda que não seja necessário ensaboar o corpo inteiro.

Outro ponto levantado pelos cientistas é que a água quente causa secura e irritabilidade na pele, retirando do corpo as bactérias benéficas que ajudam no combate a infecções."

Sobre cortar com o açúcar - uma história

http://www.bbc.co.uk/bbcthree/item/a3cc65e5-c8e7-4d03-b6a1-23eb638daf6e

Citando:
"The constant bad news about sugar has suddenly got to me. There are stats showing that sugar consumption is at its highest level in history. The government is trying to get the food industry to cut the amount of sugar in popular products like chocolate bars by 20% by 2020.

I realise that I am the average UK adult, who consumes at least 15 teaspoons of sugar a day. (This may sound a lot, but there are seven teaspoons in just one fizzy drink can.) The World Health Organisation recommends eating just six.

A high-sugar diet is linked to obesity, and being overweight can increase the risk of getting Type 2 diabetes.A 2014 study found that there is a much higher risk of dying from cardiovascular disease among people who get a lot of their calories from added sugar."

Omeprazol (protector do estômago) e risco de cancro de estômago?

Notícias ao Minuto - Estudo relaciona a toma de Omeprazol com risco de cancro de estômago

Citando:
"Um estudo realizado pela Universidade de Hong Kong em parceria com o University College London, publicado pela revista científica 'Gut' na passada terça-feira, alerta para os riscos do uso prolongado de medicamentos da classe do Omeprazol, como o Lansoprazol, Pantoprazol, Rabeprazol, Esomeprazol e Dexlansoprazo.

De acordo com o estudo, este tipo de medicamentos 'protetores' do estômago - Inibidores de Bomba de Protões (IBP) - aumentam até 2,4 vezes o risco de cancro no estômago quando tomados de forma recorrente, uma ligação já estudada anteriormente pela ciência."
