Plant Based Diets Growing in Popularity

Plant-based diets are no longer just a trend – they’ve become a lifestyle choice embraced by people for a variety of compelling reasons. From health benefits to environmental concerns and ethical values, the shift toward more plant-centric eating has gained momentum in recent years. But how did it all start, and what’s fueling this growing movement?

In this blog, we’ll take a closer look at the history of plant-based diets, unpack the key factors behind their rising popularity and share tips to help you eat more plants.

The basics of a plant-based diet

What to know: A plant-based diet focuses primarily on foods derived from plants, including fruits, vegetables, grains, nuts, seeds and legumes. While the term doesn't always require eliminating all animal products, many people adopt this approach with minimal or no reliance on meat, dairy or eggs. 

A plant-based diet emphasizes whole, unprocessed foods from plant sources for a nutrient-dense, sustainable and health-conscious way of eating.

• Fruits and vegetables are staples of plant-based diets, ranging from citrus fruits to hearty root vegetables.
• Whole grains (quinoa, brown rice, oats and whole grain bread or pasta) are a vital component of plant-based diets because they’re rich in fiber, vitamins and minerals.
• Instead of protein and fat from animals, plant-based diets focus on legumes (lentils, chickpeas and beans) and nuts and seeds (almonds, walnuts, flaxseeds and chia seeds).

There are many benefits to plant-based diets.

• Plant-based foods can significantly lower the risk of heart disease by reducing consumption of saturated fats found in animal products and incorporating fiber-rich foods.
• Plants are lower in calories yet high in nutrients, making it easier to achieve or maintain a healthy weight.
• A diet centered on plant-based foods has been linked to a decreased risk of chronic illnesses, including type 2 diabetes, cancer and high blood pressure, due to the high concentration of antioxidants, vitamins and minerals.

History of plant-based diets

Key points: Plant-based diets date back thousands of years, with early adoption seen in cultures like India and Greece, where they were often linked to religious and philosophical beliefs.

Plant-based diets may be new to some, but they’re rooted in ancient cultures and have evolved significantly over time. 

• While often viewed as a modern trend, the practice of favoring plant-based foods – whether for health, ethical or spiritual reasons – dates back thousands of years.
• The earliest records of plant-based diets appeared as a part of ancient Indian traditions, particularly Hinduism, Buddhism and Jainism.
• Indian religious texts emphasized refraining from killing animals and consuming meat.

The vegetarian movement emerged in the 19th century in Britain and the United States.

• With the 1847 establishment of the Vegetarian Society in England, the group formalized vegetarianism as a lifestyle choice.

Veganism, meanwhile, developed in the mid-20th century as a more radical offshoot. 

• The word “vegan" referred to people who eliminated all animal products, including dairy and eggs, from their diet.
• This movement was based on ethical concerns for animals as well as environmental and health considerations.

The 1970s and 1980s witnessed a rise of plant-based food pioneers who developed products such as tofu burgers and soy milk.

• However, this market was small – the widespread adoption of plant-based diets truly accelerated in the 21st century due to a combination of environmental concerns and more health-conscious choices. 

Why have plant-based diets become so popular?

At a glance: Since 2000, there has been a surge in the popularity of plant-based diets, transforming what was once seen as a niche movement into a mainstream lifestyle embraced by millions. This shift is the result of a confluence of factors, including greater awareness of health benefits, environmental challenges, ethical concerns and advancements in food technology. Millennials and Gen Z are the strongest advocates for plant-based eating.

Health is a primary motivator for people adopting plant-based diets.

• Research has consistently highlighted the link between plant-based eating and a reduced risk of various illnesses.
• For example, studies have shown that diets rich in whole plant foods improve cholesterol levels, lower blood pressure and lead to a healthier weight.
• As streaming platforms have grown in popularity, so have documentaries on healthier eating that have inspired a wide audience to rethink their dietary habits.

The environmental impact of animal agriculture has also driven the rise of plant-based diets. 

• Issues such as deforestation, greenhouse gas emissions and water scarcity associated with livestock farming have spurred global discussions about more sustainable food systems.
• A growing number of environmental advocates have called for reduced consumption of animal products.
• The idea is that a shift to plant-based eating could play a role in mitigating climate change and preserving natural resources.

Culinary advancements in plant-based meat and dairy alternatives have made plant-based eating more accessible. 

• Many companies pioneered a new wave of products aimed at mimicking the taste, texture and nutritional value of animal products.
• For example, even fast food chains now offer items such as plant-based burgers and plant-based chicken.
• In 2023, the U.S. plant-based retail market was worth $8.1 billion, according to the Good Food Institute.

Tips for starting a plant-based diet

The takeaways: Transitioning to a plant-focused diet can feel like a big change, but with small, thoughtful steps, it can become an enjoyable and sustainable part of your lifestyle. Schedule an appointment with a registered dietitian to help you get started on a particular diet or to support you with your diet goals! 

Focus on variety, experiment with new recipes and be sure you’re getting enough protein and essential nutrients.

Start gradually by incorporating plant-based meals a few times a week. 

• Begin by swapping animal ingredients for plant-based alternatives.
• Add an extra serving of vegetables to your lunch or dinner.
• Replace dairy milk with almond, soy or oat milk in your coffee or smoothie.
• Try a meatless day each week, such as "Meatless Monday."

Explore protein-rich options to add variety to dishes.

• Legumes such as lentils, chickpeas and black beans are versatile and affordable. Beans plus beans creates a complete protein source for those following a plant based diet – offering all nine essential amino acids necessary for human health. 
• Tofu and tempeh are ideal substitutes for meat and take on the flavor of your seasonings.
• Nuts and seeds, such as almonds, chia seeds and sunflower seeds, are great for snacks or adding crunch to meals.
• Whole grains such as quinoa and farro provide both protein and complex carbs.

Experiment with new flavors and recipes.

• Keep the meals exciting by exploring different cuisines and flavor combinations.
• Examples include Indian curries, Mediterranean grain bowls or Asian stir-fries.
• Try ingredients like tahini, nutritional yeast or miso to enhance the taste and explore new flavors.

Learn about balanced plant-based nutrition to avoid deficiencies. 

• Certain nutrients, such as vitamin B12, iron, calcium and omega-3 fatty acids, are more commonly found in animal products.
• To avoid deficiencies, eat fortified foods or take supplements.
• For example, nutritional yeast can provide vitamin B12, while flaxseeds and walnuts are great sources of omega-3s. Studies have shown that supplementing B12 is more effective than relying on fortified foods like nutritional yeast alone.
