Official Summary

Dr. Josh Axe, bestselling author of Keto Diet and Eat Dirt, explains how to lose weight, prevent disease, improve your digestion, and renew your youth by taking advantage of dietary collagen.

Today, interest in dietary collagen is growing at an astounding rate, and with good reason. The benefits of a collagen-rich diet are remarkable, ranging from better weight control to enhanced digestion, clearer skin, reduced inflammation, and improved immune function.

Dietary collagen provides a unique blend of amino acids and other compounds, making it critical for everyone, including infants, young children, the elderly, athletes, pregnant women, new mothers, and adult men and women. Simply put: When we don’t get enough of the beneficial compounds found in collagen-rich foods, we experience more injuries, chronic aches and pain, digestive issues, and other symptoms associated with aging. And most people don’t get enough. Collagen is the missing ingredient that can help all of us live longer, healthier, more vital lives.

In The Collagen Diet, Dr. Axe describes how collagen helps maintain the structure and integrity of almost every part of the body. You’ll learn how your skin, hair, nails, bones, disks, joints, ligaments, tendons, arterial walls, and gastrointestinal tract all depend on the consumption of collagen-rich foods.

Featuring a twenty-eight-day meal plan, seventy mouthwatering recipes, and specific advice for supporting your body’s collagen production with exercise and lifestyle interventions, The Collagen Diet provides everything you need to take advantage of this overlooked cornerstone of modern health.

I picked up The Collagen Diet not because I’m actually interested in a new diet, and particularly not specifically around collagen, but because I wanted to know what the health benefits of eating collagen might be and why someone would propose an entire diet based on it. Personally, I’m skeptical of any author who encourages “cleanses” and even more skeptical of an author who has an entirely different book advocating for an entirely different diet—keto (So which is better, Dr. Axe?  Collagen or keto?), but I did learn some interesting things about the research on collagen, which was my main goal.

There are several chapters in the front of the book about collagen and its benefits and the research that has been done on it, much more information than I would expect to get just Googling “benefits of eating collagen,” which is certainly something I could have done instead of reading this book.  Dr. Axe posits it as life-changing, good for everything from helping his mother’s cancer to aiding in the alleviation of arthritis.  Personally, I’m convinced enough from the research he cites to believe that, yes, this could be worth adding to your diet…if only it weren’t in so few foods. 

There’s also a lot of technical information about different types of collagen, how they work, what foods they can found it, and what foods they should be eaten in combination with to get the full benefits.

The idea that there is a collagen diet is still a bit unconvincing to me, however, based on the fact that it is found in so few foods—including egg shell membrane, which is basically impossible to just eat.  The basic gist of the diet is honestly that you should just eat tons of bone broth and buy a collagen supplement and maybe try to get in some gelatin here and there.  Really, that’s it.  Many of the breakfast recipes, for instance, are smoothie recipes to which you add a collagen supplement.  The other recipes largely call for getting in bone broth somehow, such as making a tomato or squash soup with bone broth.  I don’t think anyone needs an entire book to suggest eating a supplement and eating tons of bone broth to them.  And the other information is general diet advice—eat a variety of fruits and vegetable, avoid sugar, get enough sleep, and exercise.  Not exactly ground-breaking.

If you want to learn about collagen, this book will work.  I wouldn’t personally recommend it for the actual diet.  At the least, I’d probably get the book from the library and skim through it first to see if the recipes are something you’d actually frequently make, or if you’d just go for a supplement and eat whatever you normally eat.

    Great review Briana! I’m also skeptical of cleanses and cook books that promote a ‘fad diet’ though I suppose with the amount of research present in this perhaps it could be labelled as more of a lifestyle change diet? I’m happy just eating without much care toward my collagen intake though, haha.


    • Briana | Pages Unbound says:

      Yeah, I think the cleanse aspect and the focus on one nutrient is what makes it a bit weird. I could see arguing people should eat more collagen than they do currently, but why would I want a 28 day diet focused on sticking collagen into every meal? That seems excessive and kind of designed to make me miss out on other healthy foods.

    One of my friends pointed out that collagen gets digested in the stomach so it’s probably not that beneficial to purposely go out and eat collagen (although I do love foods like motsunabe and pig skin). I think the advice to eat better, exercise, and sleep is good but not worth buying a book for.


    • Briana | Pages Unbound says:

      Interesting! The book definitely didn’t mention that!

      I mostly checked it out because I saw it at the library and thought, “I wonder why this guy thinks collagen is so great?” But revolving your entire diet around one thing seems ridiculous in the first place. Like, should I start the “Vitamin C diet” just because eating enough Vitamin C is good for you???

      I also find the eat right, exercise, and sleep advice to be a bit exhausting. I mean, it’s probably RIGHT, but it’s a bit depressing when everything seems to come down to “If you just change your entire lifestyle and also probably never eat sugar or dairy and also eliminate all stress in your life, your health will be great!” Yeah, sounds…doable. :/

    I’m also skeptical of books promoting fad diets and maybe diets in general. They so often seem based on awful science, giving other scientists a bad name.
