Peanut butter bars

Gnu Foods Flavor & Fiber Peanut Butter Bar

HK$24 for 45 grams, Just Green

This does contain a lot of fibre - a whopping 12 grams, or nearly half your daily need - per bar, but the flavour is sadly lacking. However, if you can get past the taste, it's a nutritious 140-calorie snack made with six whole grains and sweetened by 100 per cent fruit juice.

Verdict: neither 'chewy' nor 'delicious' as claimed.

Think Thin Creamy Peanut Butter

HK$24 for 60 grams, Nature's Village

Take the claim that 'managing your weight never tasted so good' with a pinch of salt - this high-protein bar is pure function over flavour. It has the texture of a dense cake and an artificial, processed taste.

Verdict: good if you're a protein junkie (each bar has 20 grams) - but why not a juicy, tender piece of chicken instead?

Probar Sweet & Savory Cocoa Pistachio HK$35 for 85 grams, Just Green

This is pricey because it's a meal in itself: each bar packs 390 calories, 22 grams of fat, 42 grams of carbs and 11 grams of protein. Organic oats and peanut butter form the base of the bar, which also contains dates, raisins and a mixture of seeds, nuts and chunks of rich, dark chocolate for an indulgent treat.

Verdict: tastes far better than it looks - dense, moist and a good blend of flavours.
