Health-conscious eaters have long turned to liquids for help meeting their diet objectives and addressing nutritional woes. Perhaps the most prominent example of the trend has been juicing, which last year evolved into a broth craze that had diet and fitness readers trading their food processors and produce for saucepans and bone-in beef.

That trend continues with forthcoming books such as Dr. Kellyann’s Bone Broth Diet by Kellyann Petrucci (Rodale, Dec.); Brodo: A Bone Broth Cookbook by Marco Canora (Pam Krauss, Dec.); The Bare Bones Broth Cookbook by Ryan Harvey and Katherine Harvey (HarperWave, Jan. 2016); The Bone Broth Secret by Louise Hay and Heather Dane (Hay House, Jan. 2016); and Bone Broth: Essential Recipes and Age-Old Remedies to Heal Your Body (Sonoma, Jan. 2016).

This season brings a new spin beyond broth: the soup cleanse, also called souping. Several books on soup diets will be published in the next few months, among them Souping by Alison Velázquez (DK, Dec.), who launched her Soupology cleanse program and product line in Chicago a year ago.

Other titles include The Healthy Soup Cleanse Book by Britt Brandon (Adams Media, Jan. 2016); Soupelina’s Soup Cleanse by Elina Fuhrman (Da Capo, Feb. 2016); and Power Souping by Rachel Beller (Morrow, Mar. 2016).

“Soup has grown out of the broth trend,” says Sarah Pelz, executive editor at Grand Central, which published Sally Fallon Morell and Kaayla T. Daniel’s Nourishing Broth in 2014. In December, the publisher will release The Soup Cleanse by Angela Blatteis and Vivienne Vella.

As with broth, soup cleanses have the sheen of celebrity. The authors of The Soup Cleanse co-own Soupure, a Los Angeles–based company that has garnered attention from Gwyneth Paltrow’s Goop website, and from The Hollywood Reporter, which called souping “Hollywood’s newest cleanse.”

In addition to its purported health benefits, which according to Pelz include weight loss and better skin, souping offers a seasonally appropriate alternative to juicing, which has a distinctly summertime vibe. “It’s winter. It’s cold out. At this time of year, having soup all day long sounds so much more appealing than doing a juice cleanse,” Pelz says.
