Plant-based diet has made a huge difference in a world of processed foods and ready-to-eat meals. Scientific research shows that vegetables, fruits, legumes, whole grains and healthy fats reduce the risk of many modern-day health issues. Fitness and nutrition experts also agree that a diet composed of mainly plant-based foods has a positive impact on your physical and mental well-being. In this article, you will learn about the foods to eat and avoid on a plant-based diet, get a menu plan, learn how a plant-based diet is different from a vegan diet, and the health benefits and side effects of this diet. Scroll down!

What Is A Plant-Based Diet, According To Experts

Diana Gariglio-Clelland, RD, says, “A plant-based diet is one that emphasizes fruits, vegetables, legumes, nuts, seeds, and whole grains over animal products like meats and dairy products.” A plant-based diet is also flexible. As per the Harvard Medical School, there are numerous types of plant-based diets, from “flexitarians” (people who primarily eat a vegetarian diet but have meat occasionally) to vegans who don’t consume any type of animal product (1).

Jenn LaVardera, RD, agrees. She says, “A 100% plant-based diet consists entirely of plant foods. That said, plant-based eating does not need to be black and white. Some people choose to eat mostly plant-based but may occasionally include animal-based foods like cheese, eggs or fish.”

There are two types of plant-based diet:

  • 100% plant-based diet
  • Flexitarian diet, where people occasionally consume animal products

But is a vegan diet equivalent to a 100% plant-based diet? No – there’s a fundamental difference between a plant-based diet and vegan diet. What’s that? Find out below.

Plant-Based Diet Vs. Vegan Diet

  • Vegan diet excludes animal products completely. Nicole Stevens, MScFN, RD, says, “The term plant-based diet is sometimes used interchangeably with the term vegan diet. However, a vegan diet would exclude all animal products entirely.”
  • Veganism is a lifestyle that extends beyond diet or food habits. Vegans avoid any clothes, shoes, hair care and skin care products, perfumes, and makeup products that contain animal products or have been tested on animals.
  • The vegan diet helps reduce carbon footprint. Reducing intake of animal meat can help reduce the effects of climate change.

While the two diets are different, they both have their benefits. The next section discusses the benefits you will reap from a plant-based diet. This diet gives you the choice to either consume only plant-sourced foods or include animal products occasionally. Check them out below.

Why Is A Plant-Based Diet Good For You?

There are several reasons a plant-based diet could be good for you. Jenn LaVardera, RD, says, “Plant foods are nutrient-dense and provide health-promoting nutrients including fiber and phytochemicals (compounds in plants with antioxidant properties) that you don’t get in animal foods.” Here’s a complete list of the science-backed benefits of a plant-based diet:

1. May Help Manage Diabetes Type 2

Consuming vegetables, fruits, whole grains, nuts, and legumes helps lower the risk of diabetes type 2 (2). An increase in fiber and micronutrients and reduction in sugar and saturated fat intake also can help manage diabetes type 2 and reduce diabetes-related complications (3), (4).

2. May Lower The Risk Of Cardiovascular Disease

According to the American Heart Association, a 100% plant-based diet has shown positive results in reducing the risk of cardiovascular disease and stroke (5), (6). Decreased consumption of meat and saturated fat can contribute to heart health. A reduction in total body fat is also an added advantage that helps lower the risk of CVD.

3. May Aid Safe Weight Loss

Plant-based diets are your safest bet for weight loss. Such diets are loaded with dietary fiber, antioxidants, minerals, and various phytochemicals. They were found to help reduce BMI in obese, overweight, and post-menopausal women (7). A plant-based diet may also reduce the risk of obesity-related metabolic syndrome (8).

4. May Help Reduce Migraine Headaches

Nutritional intervention with a 100% plant-based diet can also have a positive impact on headaches associated with migraines. A study showed promising results in reducing headache intensity and frequency per week (9). The anti-inflammatory and antioxidant properties of a plant-based diet could be an explanation for this outcome (10).

5. May Reduce Joint And Muscle Pain

A plant-based diet may help reduce joint pain associated with arthritis and fibromyalgia (7). A 100% vegetarian diet or lacto-vegetarian diet was found to help reduce inflammation and pain as well as psychological distress caused due to muscle and joint pain (7).

6. May Help Reduce The Risk Of Cancers

Dr. Katie Takayasu, Integrative Medicine Physician, says, “When I look at all of the evidence for living a lifestyle that prioritizes health and reduces risk of cancer, it all comes down to plants.” Yes, a plant-based diet also helps reduce the risk of cancer due to its high antioxidant content. Along with medical therapy and cancer treatment, eating a diet rich in plants can help manage various types of cancers (prostate, breast, gastrointestinal, and colorectal) (11).

In a cohort study with 126,394 UK Biobank participants, a plant-based diet was associated with significant health benefits. Participants in the highest healthful plant-based diet quartile were found to have a 16% lower risk of total mortality, 7% lower risk of cancer, and 8% lower risk of cardiovascular disease compared to the lowest quartile.

7. May Help Manage Kidney Disease

In a study, 14,686 middle-aged adults were studied over a period of 24 years (12). The study recorded 4,343 incidences of kidney disease occurring in this timeframe. Researchers found that a higher adherence to a plant-based diet slowed kidney disease progress. Plant-based diets are safe and are recommended for primary and secondary prevention of CKD (chronic kidney disease) (13).

8. May Help Control High Blood Pressure

High-blood pressure (or hypertension) can lead to a number of health complications including an increased risk of heart disease. A plant-based diet is the best dietary intervention to reduce systolic and diastolic blood pressure (14). The low-sodium content in plant-based diets is a major contributing factor in reducing blood pressure (15). The nitric oxide in plant-based diets also acts as a vasodilator and aids proper blood flow (15).

These are the 8 health benefits of a plant-based diet. It is clear that reducing or avoiding animal-based products can show great improvements in one’s health. Check out the following diet chart to get an idea on how to design your own plant-based diet plan on a day-to-day basis.

If you are new to a plant-based diet, you can get a little overwhelmed by changing your diet completely in one go. But don’t worry. Here’s a step-by-step guide to get started with a plant-based diet. Scroll down.

Beginner’s Guide To Starting A Plant-Based Diet

  • Give Your Kitchen A Makeover: This is the most important step to get started. Out of sight, out of mind – is it not? Donate all packaged foods and other foods high in saturated fats and trans-fats. Bring home fresh veggies, fruits, whole grains, healthy fats, herbs and spices, and a few animal sources of foods if you opt for a flexitarian plant-based diet.
  • Go Slow, But Be Steady: Change your diet with one or two meals per day. Start by consuming only plant-based foods in one or two of your biggest meals – breakfast, lunch, or dinner. Give yourself one week to adjust to the new food habits. You can go on a full-fledged plant-based diet from the second week.
  • Snack Mindfully: Snacking right is also very important. It is easy to consume trans-fats through plant-based snacks like potato chips. Consume nuts and seeds or a fruit or crunchy veggies like carrot and cucumber for a delicious snack.
  • Include Animal Sources Of Food, If You Want: You can be on a plant-based diet and still have animal food sources in moderation. This flexitarian concept works for vegetarians who consume milk, yogurt, cheese, eggs, etc. It also works for people trying to reduce meat, fish, and dairy consumption. The mantra is to consume more plant-based foods than animal-sourced foods.
  • Make Your Food Delicious: A colorful plate of plant-based foods should also taste good. Use different styles of cooking, check easy recipes, and create your own salad dressings and sauces to make your food delicious.
  • Reward Yourself: Adhering to your new food habits requires effort and determination. If you have done that, it’s time to reward yourself. You can buy yourself useful equipment (juicer or a whisk, etc.), post a before-after selfie on your social media, or buy yourself a book on mindfulness or meditation to keep improving your new-found lifestyle.

You can also add fermented plant-based foods like sauerkraut, kimchi, or tempeh into your diet to add some color to your meals.

Being on a plant-based diet has many benefits. However, it also may have one disadvantage.

How To Overcome Nutritional Deficiencies

Dr. Katie Takayasu, Integrative Medicine Physician at Stamford Hospital, says, “A plant-based or vegan diet could be nutritionally deficient unless the person is very cognizant of what they are choosing.” She adds, “It is important to consider things like vitamin B12 and vitamin D as those are primarily available in animal sources in the diet. So one would want to supplement those. It’s also important to make sure that you have enough iron and calcium.”

How to overcome these nutritional deficiencies? Jenn LaVardera, RD, and Nicole Stevens, MScFN, RD, offer the perfect solution:

Jenn LaVardera, RD, says “Vitamin B12 is unique to animal foods, so people eating a 100% plant-based diet should be intentional about getting enough of it. Try cooking with nutritional yeast (it’s a great substitute for cheese). Studies also show that nori can serve as a plant-based source of B12. Those following an exclusively plant-based diet might also consider taking a supplement ”(16).

Nicole Stevens, MScFN, RD, says, “Vitamin D often needs to be supplemented or consumed through eating fortified foods (always speak to a doctor before starting any supplements).” She adds “Zinc, omega-3s, iron, and iodine are also nutrients of concern. Zinc is found in nuts, seeds, whole grains, and legumes such as chickpeas or lentils. Omega-3s may require supplementation (speak to a doctor before starting any supplements) but are found in hemp seeds, chia seeds, flaxseeds, and walnuts. Iodine is found in seaweeds and fortified salts.”

Jenn LaVardera, RD, also suggests, “Iron is found in many plant foods including leafy greens, whole grains, nuts, seeds, and legumes. And vitamin C, which is found in fruits and vegetables, can help with iron absorption.”

With regards to calcium, she says, “Calcium can also be obtained from plant foods including beans, green vegetables, almonds, and sesame seeds.”

As for protein, Jenn LaVardera, RD, states, “including a wide variety of plant foods including legumes, beans, nuts, seeds, and whole grains in your day is an easy way to ensure you meet your daily protein needs.”

The key to preventing nutritional deficiencies in a plant-based diet is consuming a mix of recommended foods along with supplements (only after consulting a licensed doctor) and getting your daily dose of vitamin D by basking in the sun in the early hours of the morning for at least 10 minutes.

A plant-based diet is rich in nutrients and bioactive compounds with antioxidant properties that are essential for the body. With the absence of saturated fat, these foods help reduce the risk of cardiovascular disease. Moreover, consuming vegetables, fruits, whole grains, seeds, and nuts helps reduce the incidence of type-2 diabetes, migraine headaches, hypertension, cancer, and kidney diseases. While on this diet, you may get tempted to snack on junk foods that contain trans fats. So, avoid eating them and munch on seeds and nuts instead for better health. However, those following plant-based diets may fall short on certain nutrients like vitamin B12 and D, zinc, iron, iodine, and omega-3 fatty acids. So, their supplementation is crucial.
