Jessica Alba is "much more grounded" than Gwyneth Paltrow.

Speaking to the New York Daily News, the 31-year-old actress said: "Alicia Silverstone is a vegan, so she's the extreme side of it. Gwyneth Paltrow probably lives a very similar lifestyle, but I didn't grow up with a bunch of money, so my tips are much more grounded: repurposing things and making things at home."

The mother-of-two - who shares daughters Honor, four, and Haven, 19 months, with her husband Cash Warren - claims that her lifestyle tips are also much less expensive and extreme.

She said: "I absolutely do these things. That's why I wrote the book. There's lots of options, like delivery services for fresh produce that is organic, if people just want to do a couple of things in the book that are super-easy...You can take what you want from the book."

Gwyneth - who is married to Coldplay frontman Chris Martin - recently came under fire for admitting that her children Apple, nine, and Moses, seven, sometimes feel hungry after dinner because they don't eat carbohydrates.

The 40-year-old blonde star said: "Sometimes when my family is not eating pasta, bread or processed grains like white rice, we're left with that specific hunger that comes with avoiding carbs."
