FLORA PRO-ACTIV
€3.95 for 600ml, €6.58 per kg

As with all its rivals this drink has been “clinically proven” to lower cholesterol thanks to the presence of plant sterols (or stanols, depending on which bottle you’re reading). It will account for 42 calories and 5 per cent of your daily sugar allowance, so is on the lower end of the bad-for-you scale. The strawberry flavours are subtle, and there is a hint of artificial sweetener. It has a thin consistency, which helps when it comes to knocking it back.

Verdict: A reliable option.
Star rating: ***

0 of 3

This has twice as many calories as some of its rivals and tastes better for it. It tastes similar to better-known yoghurt drinks and has a sweetness that will, perhaps, not appeal to everyone. A single small bottle equates to 15 per cent of an adult's daily allowance of sugar, which is high. The price is anything but high.

Verdict: Great value.
Star rating: *****


DANACOL
€4.99 for 600ml, €8.31 per kg

This product is reminiscent of those weird pink medicines of yore. You could knock it back but it is not enjoyable. Despite the promise of strawberry flavours, the biggest flavour that comes through is from the artificial sweeteners that have been added to the mix in a misguided attempt to make this taste nice.

Verdict: Hmmm, Danone.
Star rating: **


BENECOL PLUS
€5.19 for 405g, €12.81 per kg

Like the option from Mr Tesco this is very sweet and we liked it for that although it does detract from its healthiness. While all the other brands sell 100g portions, Benecol has managed to cram all its plant stanol goodness into just 67.5g or a single mouthful which is, we reckon, to its credit. It is the best-known of the drinks and very widely available but it does come with a higher price.

Verdict: Good but not great value.
