Apples for healthy weight
Apples have a GI of 38, making them a low-GI food. Foods with a GI of less than 55 make you feel full for longer and help control appetite. They also prevent your blood sugar from spiking and then crashing.
To manage weight and aid weight loss, doctors recommend a diet rich in fibre. Apples are high in soluble fibre. This means that they make you feel full without needing to consume lots of calories. The fibre in apples also aids digestion, and assists your body in absorbing nutrients.
Apples are excellent for boosting energy, so they’re a perfect pre or post exercise snack. Some studies have shown that apples may even help to speed up your metabolism, so the calories you consume after eating an apple could burn off quicker.
Choosing apples
Choose apples that are firm with good colouring, and avoid apples with soft or dark spots. When you hold an apple in the palm of your hand, it should feel solid and heavy. Avoid apples that are soft and light. Check that apples don’t wrinkle by running your thumb gently across the skin. Also check that there’s no roughness and browning close to the stem (this is known as russetting).
Although colours vary for some types of apples, yellowness in Granny Smiths, for example, indicates that they are overripe. Overripe apples release something called ethylene gas, which stimulates the ripening and rotting of other apples and fruit around them, including pears.
Some apples are speckled with little dots, called lenticels. These are the pores that the fruit breathes through, and their colour can indicate how ripe the fruit is. Avoid apples with very dark brown or pitted lenticels.
