Não julgar os alimentos apenas pelo conteúdo calórico (Paradoxo Francês)?

http://www.dailymail.co.uk/health/article-4533174/Don-t-judge-food-based-solely-s-nutrients.html

Citação:
"Cheese does not cause substantial heart disease despite its saturated fat levels
Chemical reactions occur within food when it is eaten with other products
The benefits of food cannot be calculated based on its individual nutrients
Cheese and almonds are high in fat but this appears to pass through the gut

Eating plenty of cheese is healthier than you think and does not necessarily increase your risk of heart disease, cancer and diabetes, according to new research.

Researchers looked into the 'French paradox' where a high cheese consumption is not linked to increased heart disease."

O álcool e as calorias

Artigo interessante com alguma informação das calorias médias de bebidas comuns e a necessidade de inclusão dessa informação nos rótulos para maior consciencialização de quem bebe:

http://www.bbc.com/news/uk-35211341


Citando:
"The LGA says calories from alcohol are classed as "empty calories", with no nutritional value, and by drinking alcohol, the amount of fat the body burns for energy is reduced. "
(...)
"It also says a pint of cider at 4.5% has 216 calories and is the equivalent to three-quarters of a burger, while a single spirit at 40% is 61 calories or an eighth of a burger.
Over 24 hours, drinking five pints of beer at 4% strength is the equivalent to eating more than three burgers. A bottle of wine - about four small 175 ml glasses - has the same calorie count as more than two burgers, the association says."

Privação do sono e apetite

Privação do sono e (maior) consumo de calorias abordados em novo estudo:


http://www.telegraph.co.uk/science/2016/11/02/sleep-deprivation-feeds-hunger-around-four-extra-slices-of-toast/


Citando:
"This study found that partial sleep deprivation resulted in a large net increased energy intake of 385 kcal per day.
If long-term sleep deprivation continues to result in an increased calorie intake of this magnitude, it may contribute to weight gain."
Dr Pot added: "Reduced sleep is one of the most common and potentially modifiable health risks in today's society in which chronic sleep loss is becoming more common.""

Obesidade infantil estudada (e melhor compreendida agora)

...e melhor compreendida:
http://www.mirror.co.uk/science/scientists-think-know-what-causes-8790932
Citando:
"Prof Wilkin said calories are burnt off in two ways - voluntary spend through physical activity and the much larger involuntary spend, simply to stay alive.
Thinking, keeping blood warm, and keeping the heart, liver and kidneys working together use up to 1,600 calories per day in adolescence."
(...)
"Burning calories uses a fixed amount of oxygen, so the children rested in a sealed canopy and their oxygen consumption was measured over a period of time, to enable researchers to calculate their calorie use from the amount of oxygen consumed."
(...)
"Prof Wilkin said: "When we looked for an explanation for the rising obesity in adolescence, we were surprised to find a dramatic and unexpected drop in the number of calories burned while at rest during puberty.
"We can only speculate as to why, but it could be a result of an evolutionary trait to save calories for growth that may now contribute to a dangerous rise in adolescent obesity in cultures where food is in abundance.
"It could be that we have evolved to preserve calories to ensure we have enough to support changes in the body during puberty, but now they have sufficient calories each day, the drop in spend means excess weight gain.""

As calorias que ingerimos podem estar subestimadas (PDF)

O problema não é exercício a menos, são calorias a mais (e os fabricantes não ajudam porque confiam que as contamos):
http://theconversation.com/is-it-our-fault-if-we-eat-too-many-calories-63730


Citando:
"The mystery of two conflicting stats was recently solved. On the one hand, official statistics show a decline in calorie consumption across the UK over the last 40 years and, on the other, the population has gained weight over the same period; obesity is on the rise.
The answer comes from the Behavioural Insights Team, a former government policy unit, which reported an increase in the number of people under-reporting the number of calories they consume. People are buying more food and eating as much as 1,000 calories a day more per person than surveys would suggest. And the way that food is marketed offers a number of insights for why this is the case.
The false message from the statistics is not altogether surprising. The main reasons listed in the report are that calorie intake is under-reported, particularly by obese people, increased snacking (which is often not taken into account when people report their calorie intake), and a problem with people eating more than the recommended portion size."
Referido também o halo effect: Se eu comer uma folha de alface, posso comer um prato de batatas fritas.
Os fabricantes / restaurantes também têm de ajudar: Se uma pizza tem 1000 calorias, quem é que come apenas uma quarto de pizza?

Reduzir calorias reduzindo... O tamanho!

Redução de calorias de gelados da forma mais saudável possível: reduzindo o tamanho (mas convenientemente mantendo o preço):
http://m.independent.ie/life/food-drink/food-news/cornetto-and-magnum-to-shrink-significantly-but-the-price-will-remain-the-same-34390506.html


Parecido com a eventual futura redução do tamanho dos pacotes de açúcar de café (7-8g para 3-4g)?
