Keira and Sienna go tum-to-tum

'Homely' Keira Knightley beats 'man-eating' Sienna Miller when it comes to the sexiest stomach, a new survey has revealed. And in another gut-wrenching blow, 63-year-old Helen Mirren also topped Sienna in the nationwide poll.

The survey, conducted by AntiBloat (antibloat.co.uk), has provided yet another problem for Sienna, in the form of tummy troubles! In the same week that she was seen cavorting topless with a married man, twice-her-age Helen was given sex symbol status when spotted with a super svelte stomach.

According to 2,000 Britons questioned, youth doesn't guarantee a sexy waistline, and AntiBloat spokesperson Jalal Janmohamed says, "The survey results reveal that a sexy stomach isn't governed by age, which is good news for all those wanting to tone up or maintain a flat tummy, something AntiBloat can help with.

"AntiBloat with its clinically-researched selection of pro- and prebiotics, is specially developed to help with abdominal bloating which is usually associated with over-eating, food intolerances, constipation, intestinal gas, PMS (or PMT) and menstruation."

The survey, which pitted The Edge of Love co-stars against each other in a very different "Battle of the Bulge", saw both men and women rating Kiera's tum above Sienna's. Pop princess, Rihanna also joined the top-three table of tums, showing the nation that whatever shape or size you are, you can still have a sexy stomach.

Independent nutritionist Sue Lloyd, says, "It is becoming increasingly known that a daily dose of probiotic bacteria is useful to correct the balance of "bad" bacteria in the gut, helping to restore and maintain healthy digestion.

"Opting for a sugar-free, preservative-free, shelf stable probiotic in supplement form is therefore an effective solution to our modern day digestive needs. To achieve optimum benefits for your digestive health, it's important to look beyond the supermarket refrigerator."

When digestion is poor, waste material and the gases they produce can remain in the gut for long periods of time - often at high temperatures and pressures - and stretch the gut walls beyond their comfortable limits.

AntiBloat is available at Antibloat.co.uk, along with the complete DTECTA Probiotics range of supplements, which use specialised formulations of clinically-researched probiotic strains to support specific health conditions.
