Drinking coffee could help you live longer
Coffee not only helps you feel full of beans, it might add
years to your life as well, two major studies have shown.
Scientists in Europe and the US have uncovered the clearest
evidence yet that drinking coffee reduces the risk of death.
One study of more than half a million people from 10
European countries found that men who downed at least
three cups of coffee a day were 18% less likely to die from any
cause than non-coffee drinkers. Women drinking the same
amount benefited less, but still experienced an 8% reduction
in mortality over the period measured.
Similar results were reported by American scientists
who conducted a separate investigation, recruiting 185855
participants from different ethnic backgrounds. Irrespective of
ethnicity, people who drank two to three cups of coffee daily
had an 18% reduced risk of death.
Each of the studies, both published in the journal Annals
of Internal Medicine, showed no advantage from drinking
either caffeinated or decaffeinated coffee. Experts believe the
antioxidant plant compounds in coffee rather than caffeine are
responsible for the life-extending effect. Previous research
has suggested that drinking coffee can reduce the risk of
heart disease, diabetes, liver disease, and some cancers.
Dr Marc Gunter, from the International Agency for
Research on Cancer, who led the European study with
colleagues from Imperial College London, said: “We found
that higher coffee consumption was associated with a lower
risk of death from any cause and specifically for circulatory
diseases and digestive diseases. Importantly, these results
were similar across all of the 10 European countries, with
variable coffee drinking habits and customs. Our study also
offers important insights into the possible mechanisms for the
beneficial health effects of coffee.”

Gabarito comentado
Resposta correta: B
Tema central: interpretação de texto informativo-científico. A questão exige identificar uma afirmação presente no texto — habilidade básica em provas: localizar informação explícita e evitar inferências não suportadas.
Resumo teórico e estratégia: em textos científicos curtos procure por afirmações diretas (ex.: “Previous research has suggested…”). Para responder:
- Leia as frases-chave;
- Substitua as alternativas por paráfrases e verifique correspondência literal com o texto;
- Elimine opções que extrapolam ou contradizem informações explícitas.
Justificativa da alternativa B (correta): o texto afirma que “Previous research has suggested that drinking coffee can reduce the risk of heart disease, diabetes, liver disease, and some cancers.” A alternativa B afirma exatamente que o consumo de café pode reduzir o risco de doenças hepáticas (liver disease) — corresponde literalmente ao enunciado.
Análise das incorretas:
- A: Errada — o texto diz que os compostos antioxidantes, não a cafeína, são provavelmente responsáveis; portanto não afirma que a cafeína tem efeito maior.
- C: Errada — o texto afirma que não houve vantagem entre caffeinated e decaffeinated, mas não afirma que descafeinado “não faz mal” a quem não pode ingerir cafeína (isso extrapola para segurança clínica).
- D: Errada — os percentuais citados variam: 18% (homens 3+ xícaras) e 8% (mulheres na mesma condição) no estudo europeu; no americano, 2–3 xícaras foram associadas a 18% de redução “irrespective of ethnicity”. Não há afirmação sobre 1–2 xícaras reduzindo risco em 18% dependendo da etnia.
- E: Errada — contradiz o texto, que relata benefícios e estudos publicados (Annals of Internal Medicine) apontando redução de risco, não inadequação do café.
Fontes citadas no texto original: Annals of Internal Medicine; International Agency for Research on Cancer (IARC). Recomendo ler resumos em periódicos e comunicados da IARC para prática de interpretação em textos científicos.
