If you or a loved one has recently learned that you have chronic kidney disease, we know that you are going through a difficult time. Fortunately, as you will find in the pages that follow, by modifying your diet, you can do a great deal to not only help protect kidney function but also improve your overall health. Better yet, you can actually make your diet more pleasurable by adding foods that are a delight to eat. This book will show you how it’s done.
The idea for this book took root several years ago, when Vicki received a devastating diagnosis of Alport Syndrome, a genetic condition that causes chronic kidney disease (CKD). Although the doctors stated that nothing could slow the progression of the disease, our research showed that good dietary choices and exercise could help protect the kidneys. Both of us began following a kidney-protective, heart-protective diet with wonderful results. Although the doctors had predicted that Vicki would need a transplant or dialysis within three years, it was six years before her kidneys failed, and during that time, she remained energetic and able to work full-time. At that point, Jennifer insisted on giving her mom one of her own kidneys. Surgery was easy for both of us, and recovery was fast. Afterwards, we continued our kidney-protective diet.
What was distinctive about the diet we adopted? In addition to cutting out red meat and reducing the consumption of other meat, sugar, and processed foods, which place a burden on the kidneys, we added lots of fruits, vegetables, and other foods that can slow or stop the progression of CKD. We found that the easiest and most delicious way to incorporate these health-building foods in our diet was with smoothies. No other nutritious meal or snack can be made from scratch in only a couple of minutes, and none provides health-enhancing benefits in such a concentrated form. These one-mug wonders became one of the mainstays of our diet. They allowed us to maintain our busy schedules and keep involved in life while enjoying great taste.
However, Smoothies for Kidney Health is more than a cookbook. It is also designed to help you understand both kidney function and kidney disease, and guide you in making smart lifestyle choices that can prolong the health of your kidneys and heart.
Part One of the book focuses on the kidneys, their function and their dysfunction. Chapter 1 begins by reviewing the important tasks performed by the kidneys. It also discusses the common and often avoidable causes of CKD and the natural decline in kidney function that occurs as you age, as well as the partnership between heart and kidney disease.
Chapter 2 explores the connection between CKD and diet. While CKD can have several causes, nearly 80 percent of all cases are the result of eating too much of the foods that contribute to type 2 diabetes, high blood pressure, and obesity―common disorders that can lead to kidney disease. Chapter 2 ends with a discussion of whether we are setting our children up for CKD by establishing poor dietary habits.
As you may already know, food choices directly impact kidney function. Based on the latest studies, Part Two further explores the connection between good food and good kidney and heart health.
Chapter 3 first discusses the best diet for preserving kidney function and then examines the components of this diet that have healing properties. As you’ll see, antioxidants, phytochemicals, and fiber―found in whole fruits, vegetables, nuts, beans, and seeds―are natural disease fighters. (And what’s the easiest way to get these nutritional superheroes on your side? Smoothies!)
If you’re already suffering some of the disturbing symptoms of kidney malfunction―acidosis and imbalances in potassium and phosphorus, for instance―you’ll probably want to learn how appropriate food choices can help alleviate these specific problems. That’s the focus of Chapter 4. An inset presents guidelines for people who still have some kidney function and want to preserve it, and a special section addresses people who have received kidney transplants and want to optimize the health and survival of their new kidney.
By the time you reach Part Three, you’ll be ready for serious smoothie making. After Chapter 5 answers the question, “Why Smoothies?,” Chapter 6 provides valuable advice on choosing your smoothie ingredients and achieving blending success. Then, the remaining chapters present eighty delicious symptom-relieving smoothie recipes. The recipes have been divided into three groups to accommodate individuals who are at different stages of CKD and have altered dietary requirements.
Chapter 7 includes forty-five smoothies for people who wish to avoid CKD, or who already have this disorder and want to slow or even halt its progression. The ingredients in these recipes are designed to help lower proteinuria; decrease blood pressure; reduce creatinine levels and estimated GFR (markers of CKD progression); and reduce acidosis, uric acid levels, and internal inflammation.
Chapter 8 offers fifteen smoothies for people with more advanced CKD who must reduce their intake of phosphorus and potassium. At this point, individuals often struggle with food choices. The smoothies in this section make it easy to prepare delicious meals that support the kidneys and promote heart health.
Chapter 9 includes twenty smoothie recipes for people on dialysis who have substantially restricted dietary requirements. These smoothies also offer soothing relief from several of the common complications of dialysis.
Every recipe in Smoothies for Kidney Health is presented in a way that not only makes it easy to prepare a luscious meal without cooking, but also highlights that smoothie’s unique benefits. Each recipe begins by explaining how its carefully chosen ingredients contribute to kidney health and, in many cases, alleviate specific conditions like high blood pressure. Then, after giving simple-to-follow directions, it offers a tidbit of useful information about the kidneys and the foods that protect them. Finally, it presents Nutrient Values per serving, including calories, fat, fiber, protein, potassium, phosphorus, sodium, and calcium. This enables you to choose those smoothies that are in line with the dietary guidelines provided by your doctor or renal dietitian. Needless to say, these recipes emphasize fruits, vegetables, low-fat dairy, whole grains, and nuts and seeds―the foods that place the smallest burden on kidney function and are best for heart health and weight control.
A delicious, produce-filled smoothie is a powerful way to take control of your health every day. Let’s clink our smoothie glasses and offer a toast to life!
