An apple a day keeps the doctor away is a rhyme many of us can recall from our childhoods - and it may hold some truth.
Apples are rich in antioxidants called flavonoids, which have been shown to lower the risk of a premature death, particularly from heart disease.
The popular fruit has also been linked to a reduced risk of type 2 diabetes and even some cancers.
To reap the benefits, it may be best to enjoy apples whole, rather than opting for juice.
'Apple peel also has blood-pressure lowering actions similar to those of ACE inhibitor drugs,' Dr Brewer said.
Dr Basford stresses it is important to eat a varied diet and not rely on just one fruit or vegetable to keep you healthy.
一天一苹果，医生远离我
很多人从小就会说“一天一苹果，医生远离我”这句押韵的俗语，这种说法有一定道理。
苹果富含抗氧化剂类黄酮。人们已经证实，类黄酮可以降低早逝风险，尤其是心脏病导致的早逝。
苹果还与2型糖尿病甚至某些癌症的患病风险降低有关。
为获得这些益处，最好吃下整个苹果，而不是只喝果汁。
布鲁尔医生说：“苹果皮还能降血压，类似于血管紧张素转化酶抑制剂药物。”
贝斯福德医生强调说，饮食多样化很重要，不要仅仅依靠一种水果或蔬菜来保持健康。
