Plant-Based Diet
Primarily plants, but not exclusively. A flexible approach that puts vegetables, fruits, and whole grains at the center.
What Is It?
A plant-based diet emphasizes foods derived from plants — vegetables, fruits, whole grains, legumes, nuts, and seeds — without necessarily excluding animal products entirely. Unlike veganism, it's more about what you add (plants) than what you remove. It's the most flexible plant-forward approach.
How It Works
The focus is on making plants the foundation of every meal. Animal products aren't forbidden but are treated as sides or occasional additions rather than the centerpiece. Most calories come from whole plant foods, which are naturally rich in fiber, vitamins, minerals, and antioxidants while being low in saturated fat.
Potential upsides
- Can support a heart-healthy eating pattern
- Often has a lower environmental impact than meat-heavy eating
- High in fiber and micronutrients
- Flexible and socially easy to maintain
- Supports healthy weight management
- Beans and grains can be budget-friendly staples

EVIDENCE What the research says
Eating more vegetables, fruit, legumes, and whole grains is consistent with major healthy-diet guidance. A plant-based label alone does not guarantee nutritional quality: highly processed plant foods can still be high in salt, sugar, or saturated fat.
