Gwyneth Paltrow has come under fire from health experts after she warned shampoo could be linked to cancer.

Writing on her website goop.com, The Shakespeare In Love star explains her concerns arose after she read research about what she calls "environmental toxins", which are found in products such as shampoo and lotion. Paltrow claims that these toxins could be linked to a rise in diseases such as asthma and cancer in children, and warns pregnant women to be careful.

She writes, "Fetuses, infants and toddlers are basically unable to metabolize toxins the way adults are, and we are constantly filling our environment with chemicals that may or may not be safe."

However, leading bacteriologist Professor Hugh Pennington has slammed her claims, describing them as "loopy." He says, "It does annoy me when celebrities use their position to spout nonsense. They have a perfect right to their views, even if they are loopy, but they do hold a position of influence."

Other experts at British charity Cancer Research UK have also dismissed Paltrow's theories, claiming there is no evidence to support her assertion that childhood cancer rates had increased "exponentially."
