Dark chocolate that does not contain dairy or milk fats could be ideal for those who want a healthy snack.
Linda Main, diatetic advisor at Heart UK - The Cholesterol Charity - explained such a product is preferable to milk chocolate.
However, she added ordinary chocolate can still be enjoyed in small amounts as part of a balanced diet.
"This means cutting back on saturated fats that come from other sources in the diet such as meat, especially processed meat, cheese, cream, whole milk, butter … cakes and biscuits," said Ms Main.
Her comments follow a study published on bmj.com, which revealed consuming high levels of chocolate may improve heart health.
While the authors advised that further study is required to establish whether the link is direct, the confectionery was associated with a one-third reduction in the risk of developing heart disease.
However, Ms Main noted women should not exceed 20g of saturated fat per day, while the recommended figure for men is 30g.
