According to the text, meat and dairy products:
IS A VEGAN DIET HEALTHY?
By Mary Lynch
As a registered nutritionist,
the question “Is the vegan diet healthy?” is one I get all the time, especially
at this time of year.
Frustratingly, the answer is that it depends as much on
what you eat as with any other diet. Someone living purely on ready salted
crisps or chips, for example, would be technically following a vegan diet, but
it would in no way be healthy.
However, research shows that there are potential benefits to a vegan
diet. A recent study indicated that the average vegan diet is higher in vitamin
C and fibre, and lower in saturated fat than one containing meat. In addition,
statistics show that vegans have a lower BMI (height-to-weight ratio) than meat
eaters – in other words, they are skinnier.
You see, a diet without any meat or
dairy products is likely to contain a lot less saturated fat, which is related
to increased cholesterol levels and increased risk of heart disease. We also
know that fat contains more calories per gram than other foods, and so vegans
may consume fewer calories as a result. Finally, a vegan diet is generally
thought to contain more cereals, fruits, vegetables, nuts and seeds than a
non¬vegan diet.
Sounds great right?
Not quite. In terms
of micronutrients, a
vegan diet is
actually more susceptible to
being nutritionally poor. A vegan diet is naturally low in calcium, vitamin D,
iron, vitamin B12, zinc and omega-3 fatty acids. Therefore, if you follow a
vegan diet it is essential that you get enough of these nutrients through
specific vegan food sources – and may even need to take additional supplements.
We have many recipes suitable for vegans that can help, just check out our
vegan section. In our features we also have this traditional hummus recipe,
which contains tahini – a good source of calcium, zinc and iron, which are all
micronutrients hard to get a hold of on a vegan diet.
So there you have it:
going vegan does not necessarily mean you are going to be healthier. In fact, I
think that much of the improvement in diets among vegans is a result of
education rather than going meat free. In other words, if someone chooses to go
vegan they are more likely to care about what they are eating and therefore are
more likely to educate themselves on the types of foods they should and should
not be eating.

Gabarito comentado
Tema central da questão:
A questão aborda interpretação de texto em inglês, especialmente sobre saúde e o impacto do consumo de carne e laticínios nos níveis de colesterol, utilizando um artigo sobre dietas veganas.
Explicação e conceito-chave:
Entender a diferença entre informações explícitas e implícitas no texto é fundamental. No vestibular, perguntas deste tipo avaliam se você consegue identificar detalhes diretos no texto e fazer pequenas inferências.
Justificativa da alternativa correta (E):
A alternativa E) are usually responsible for rising our levels of cholesterol. está correta. No texto, lemos claramente: “a diet without any meat or dairy products is likely to contain a lot less saturated fat, which is related to increased cholesterol levels and increased risk of heart disease.”
Ou seja, o consumo de carne e laticínios contribui para maior ingestão de gordura saturada, que eleva o colesterol no sangue. Assim, essa relação direta é explicitamente afirmada pelo texto. Esta habilidade de localizar argumentos centrais e as consequências citadas é fundamental em provas de interpretação, conforme defendido em manuais como Reading and Vocabulary Development (Bailey).
Análise crítica das alternativas incorretas:
A) O texto NUNCA diz que carne e laticínios são extremamente necessários para a saúde; pelo contrário, ressalta vantagens da alimentação vegana desde que bem planejada.
B) Nenhuma informação no texto relaciona carne/laticínios ao controle de açúcar no sangue.
C) Veganos não consomem carne nem laticínios, justamente o oposto do que a alternativa indica – fique atento a pegadinhas que contrariam definições básicas!
D) Não há qualquer menção sobre estatísticas de consumo em países em desenvolvimento.
Estratégia recomendada:
• Sublinhe informações-chave ao ler textos.
• Compare as alternativas com informações explícitas do texto, evitando respostas baseadas em suposições.
• Atente-se a generalizações (“sempre”, “nunca”, “todos”) e a detalhes que contrariam definições óbvias, como o que um vegano consome.
Resumo:
A alternativa E é a resposta certa, pois está claramente respaldada no texto: carne e laticínios estão associados ao aumento do colesterol.
