Plant-Based Nutrition Basics
-
A whole-food, plant-based diet focuses on foods in their most natural or minimally processed form, including vegetables, fruits, whole grains, beans, lentils, nuts and seeds. It minimizes highly processed foods and animal products. At Plant Docs, we focus on adding more nourishing plant foods to your plate, finding healthy substitutions for more processed foods, and making changes that are realistic and sustainable.
-
A vegan or vegetarian diet is defined mostly by what you exclude, while a plant-based diet is defined by what you emphasize.
Vegetarian: Does not eat meat or fish, but may eat dairy and eggs.
Vegan: Does not eat any animal products, including meat, fish, dairy, or eggs.
Plant-based: Focuses primarily on foods that come from plants—vegetables, fruits, whole grains, beans, nuts, and seeds. It doesn’t necessarily mean 100% vegan; some people who eat plant-based occasionally include animal foods.
And importantly, “vegan” doesn’t automatically mean healthy, French fries, cookies, and highly processed foods can all be vegan. A whole-food, plant-based diet emphasizes minimally processed plant foods that benefit health text goes here
-
Absolutely. Protein is found throughout the plant kingdom. Beans, lentils, peas, tofu, tempeh, whole grains, nuts and seeds are all good sources. Eating a varied plant-based diet that provides enough food to meet your energy needs can provide plenty of protein for most people.
-
No. You don't have to be perfect to benefit from eating more whole plant foods. Increasing vegetables, fruits, whole grains, beans and other minimally processed plant foods is a positive step. At Plant Docs, we meet you where you are and help you make changes you can maintain.
-
Start with what you already eat. Add beans to a favorite soup, choose oatmeal and fruit for breakfast, swap refined grains for whole grains or make one plant-based dinner each week. You don't have to change everything overnight. Plant Docs offers recipes, cooking classes, educational programs, and support to help make the transition practical and enjoyable.
Plant-Based Nutrition & Health
-
Eating more whole, plant-based foods can support heart health, blood sugar control, healthy weight, and overall well-being. Research has shown that whole-food, plant-based nutrition can improve important health markers including cholesterol, blood pressure, and A1C. Plant Docs’ published research demonstrates significant improvements in several cardiovascular and metabolic health markers after a one-month nutrition intervention.
-
Yes. A whole-food, plant-based diet can help lower total and LDL ("bad") cholesterol. Plant foods are naturally cholesterol-free and lower in saturated fat while providing soluble fiber and other nutrients that support heart health. In the Plant Docs published Jumpstart research, participants with elevated cholesterol experienced significant reductions in total (down 38 points) and LDL (down 22 points) cholesterol in 1 month.
-
Yes. Eating a diet rich in vegetables, fruits, whole grains, legumes, nuts and seeds can support healthy blood pressure. In the Plant Docs Jumpstart study, participants at higher risk experienced significant reductions in both systolic (down 10.0 mmHg) and diastolic (down 8.7 mmHg) blood pressure after following a whole-food, plant-based nutrition program.
-
Plant-based eating can be a powerful tool for preventing and managing type 2 diabetes. Whole plant foods are rich in fiber and generally low in saturated fat, which can help improve insulin sensitivity and blood sugar control. Choosing carbohydrates in their whole form, such as beans, whole grains, vegetables and fruit is an important part of this approach.
-
Yes. Whole plant foods tend to be nutrient-dense and rich in fiber, which can help you feel satisfied without relying on calorie counting or restrictive dieting. High fiber diets naturally stimulate your own GLP-1 hormones to help regulate appetite without medication. Plant Docs focuses on creating sustainable eating habits and improving overall health rather than simply focusing on the number on the scale.
-
No diet can guarantee that you won't develop cancer, but what you eat can play an important role in cancer prevention, and overall health. A diet rich in vegetables, fruits, whole grains, beans and other plant foods provides fiber, antioxidants and phytonutrients that support the body's natural protective processes. Plant Docs teaches people how to incorporate more of these foods into everyday meals. Learn practical ways to incorporate these foods with Plant Docs Anytime: Cancer Fighting Foods

Good nutrition is especially important during and after cancer treatment. Nutrient-rich foods can help increase energy, boost immunity, and support overall health. Plant Docs emphasizes a variety of whole plant foods, including vegetables, fruits, whole grains, legumes, nuts and seeds. Nutritional needs can vary considerably during cancer treatment, so dietary changes should always be discussed with your oncology and medical team.

For most people with breast cancer, whole and minimally processed soy foods such as tofu, tempeh and edamame can safely be part of a healthy diet. Despite a common misconception, soy foods do not need to be avoided after a breast cancer diagnosis. Research shows that soy foods are safe, and some studies suggest they may even be associated with a lower risk of breast cancer recurrence. Individual circumstances vary, so people undergoing cancer treatment should discuss specific nutrition questions with their healthcare team.
