Avocado
This creamy fruit is a favourite for many people, and the good news is that avocados are very low in sugar--only 1.3 grams in a single one. That said, you should keep in mind that they are high in fat (up to 30 grams per fruit). While it is mostly monounsaturated fat (that is, the healthy kind), it means they are high in calories so you’ll want to eat them in moderation.

Rasberries
Even though they're only in season for a short time (consider freezing or canning them so you can enjoy them year round), raspberries are a winner with five grams of sugar in a cup.

Lemons
If only we could eat lemons straight--your average lemon contains only two grams of sugar. That said, even though most of us won’t eat a lemon straight, use slices or its juice to brighten up your dishes with some tartness.

Strawberries
If you’ve been using strawberries as a staple in your smoothies and salads, you’re OK to continue doing so--strawberries contain seven grams of sugar in a cup, so they’re low in sugar when compared to cherries, for example, which contain 18 grams of sugar in a cup.

Blueberries
If looking to limit your sugar intake, you’re better off consuming raspberries, strawberries and blackberries as these three types of berries contain less sugar than blueberries, which boast 10 grams of sugar in 100 grams. But blueberries still rank better than some other favourites (like mangoes, which contain 14 grams of sugar in 100 grams).

Apples
They're slightly higher in sugar than other fruit, but apples still don’t send your blood sugar skyrocketing at 10 grams of sugar in a 100-gram serving compared to 16 grams in the same quanitity of grapes.

Blackberries
Other berries, like strawberries and raspberries, are typically much more readily available in grocery stores, but pick up blackberries when you can as these tasty berries ring in at only seven grams of sugar in a cup.

Cranberries
Although we tend to gravitate to this fruit more in the winter, this berry should become a regular in your grocery cart when it comes to its sugar content (only four grams of sugar in a cup). Beware of the dried variety, though; dried cranberries are often sweetened (plus, dried fruit in general is high in sugar!).

Lime
Like lemons, although you wouldn’t pick one up to snack on straight, limes also ring in low when it comes to sugar content, at about two grams in a single fruit. Use it to add a bit of natural flavour to your water (flat or sparkling) rather than drinking soft drinks with added sugar.

Rhubarb
Though technically a vegetable, rhubarb is often prepared with other fruit and used in fruit dishes. It's also commonly cooked with a lot of sugar, since it's naturally low in sugar (100 grams contains just a little more than one gram of sugar). Look for recipes that limit the amount of added sugar to enjoy this treat.
