What is a plant-based diet?
These vegan-like diets eliminate all animal products, including meat, poultry, fish, eggs, dairy and honey. As the name suggests, everything you eat — including whole grains, fruits, vegetables, legumes, nuts and seeds — is derived from plants.
Are plant-based diets healthy?
Research reflects that following a plant-based diet has significant health benefits as long as you do it correctly.
“No matter when you start, a diet that is focused on plant foods will help you work toward the prevention of many illnesses and feeling better overall,” Zumpano says.
If followed properly, a whole foods, plant-based diet limitsthe use of oils, added sugars and processed foods, leaving only whole foods to provide nutrition. This maximizes nutrient intake and virtually eliminatesfoods that can lead to poor health outcomes.
These diets are low in saturated fat, free of cholesterol, and rich in fiber, vitamins, minerals and antioxidants.
Research also reveals that following this type of diet will lower your risks of:
- Heart disease.
- Hypertension (high blood pressure).
- Diabetes.
- Digestive disease.
- Colon andbreast cancers.
- Obesity.
Studies also show that a plant-based diet can help to lower body weight and reduce your LDL cholesterol.
The cons of a plant-based diet
Following a plant-based diet means saying goodbye to all animal products — including lean meat and dairy products such as milk, yogurt, cheese and ice cream.
“That’s easier said than done for many of us,” Patton says. “But when you have the right guidelines and wrap in changes over time, replacing animal products in your dietis possible.”
Another thing to note — if you don’t plan your plant-based diet correctly, you may not meet all your protein, vitamin and mineral needs. And you won’t feel or look your best if you develop a nutritional deficiency. But there are easy ways to make sure you’re getting the nutrients you need.
How to get enough protein
You’ll want to make sure that your diet includes enough protein to maintain muscle mass, strong bones and healthy skin. The following foods are packed with protein:
- Beans, lentils and split peas.
- Quinoa.
- Soy products liketempeh, tofu, soybeans andsoy milk.
- Nuts and seeds.
How to get enough vitamins and minerals
You’ll also need to get adequate calcium and vitamin D in your diet to ensure healthy bones. This won’t be difficult if you:
- Drink a milk alternative such as soy, almond, rice or hemp milk, which contain both calcium and the vitamin D needed to absorb it.
- Eat plenty of dark green leafy lettuce and beanswhich contain calcium.
- Eat mushrooms and fortified cereals which contain vitamin D. If you aren’t consuming fortified foods on a consistent basisyou’ll need totake a vitamin D supplement. Sunlight is another source of vitamin D.

You’ll also need enough zinc in your diet to support a healthy immune system, enough iron to maintain energy and immunityand enough vitamin B12 to produce red blood cells and prevent anemia. This means you’ll want to:
- Eat whole grains, beans and fortified cereals for zinc and iron.
- Eat fortified cereals and soy products to get your vitamin B12.
- Nutritionalyeast is also a great source of vitamin B12.
How to get started on a plant-based diet
“To start your plant-based diet, keep it simple. Begin by cutting out one animal product at a time,” Patton says.
- First, replace all milk and dairy products with soy, rice, almond and hemp alternatives. Use nondairy yogurt or kefir and soy or coconut-milk coffee creamer.
- Next, replace chicken, turkey, beef, pork, veal, lamb and fish with plant proteins.
- Stock up on legumes, beans, nuts, seeds and vegan meat alternatives like tofu veggie burgers, nutritional yeast, seitan and tempeh.
Be sure to include all four food groups at each meal — plant protein, fruit, vegetables and whole grain — as shown in the following sample menu.
Sample One-Day Plant-Based Vegan Menu
Breakfast
- 1 cup cooked steel cut oats mixed with 1/8 cup chopped nuts, ½ cup fresh berries, ½ cup pureed pumpkin or butternut squash and 1 tablespoon of ground flaxseed.

Lunch
- Veggie burrito (whole grain tortilla spread with vegan refried beansstuffed with mixed greens, tomatoes, peppers, onions and nutritional yeast).

“Once you begin, in time you’ll fill your kitchen with what you need and will get easier every day. A plant-based diet may seem restrictive, but you can look at it as a simpler way of eating,” Zumpano says.
