Understanding Vitamin B6
Vitamin B6, also known as pyridoxine, is an essential water-soluble vitamin crucial for numerous bodily functions. Its roles include aiding in the metabolism of proteins, carbohydrates, and fats, supporting immune function by helping to produce antibodies, and contributing to brain health. It is also involved in the creation of neurotransmitters that help transmit signals in the brain and form the protein sheath (myelin) around nerve cells. Since the body cannot produce this vitamin on its own, it must be obtained through a balanced diet or supplementation.
While B6 is found in a wide variety of foods, certain vegetables stand out as excellent sources, particularly for those on plant-based diets. Incorporating these nutrient-dense vegetables can help ensure you meet your daily intake goals and support overall well-being.
Top vegetables high in B6
Several vegetables are notable for their significant Vitamin B6 content. Incorporating a variety of these into your meals can create a flavorful and nutrient-rich diet.
Sweet Potatoes and Potatoes
These starchy vegetables are exceptional sources of Vitamin B6. A medium baked sweet potato provides about 24% of the daily value (DV), while a medium baked white potato with the skin offers around 35% DV. Baking these vegetables with the skin on helps retain their fiber and potassium content. They are also versatile and can be enjoyed roasted, mashed, or baked.
Bell Peppers
Available in a rainbow of colors, bell peppers are a great source of Vitamin B6, with green bell peppers providing 20% of the DV per cup. In addition to B6, they are rich in Vitamin C, Vitamin A, and fiber. They are easy to incorporate into salads, stir-fries, or enjoyed raw with a B6-rich dip like hummus.
Spinach
This leafy green powerhouse is rich in multiple nutrients, including B6. A half-cup of cooked spinach provides around 0.2 mg of B6, making it a great addition to soups, stir-fries, and sautés. Spinach is also an excellent source of iron, Vitamin A, and Vitamin C.
Chickpeas (Garbanzo Beans)
As a legume, chickpeas are frequently featured in lists of high-B6 vegetables and are a staple of plant-based diets. A single cup of canned chickpeas provides an impressive 65% of the daily value for B6. They are also high in plant-based protein and fiber. Chickpeas can be used in salads, curries, and blended into hummus.
Avocado
Though technically a fruit, the avocado is often used as a vegetable and is an excellent source of B6. One-half of a fruit provides about 0.26 mg of B6. Avocados are also known for their healthy fats, fiber, and other vitamins. They can be sliced on salads, mashed for guacamole, or blended into a smoothie.
Carrots
Carrots are another versatile vegetable that provides a healthy dose of B6. A single medium carrot stick supplies a comparable amount of B6 to a glass of milk. They are also famously high in Vitamin A. Enjoy them raw, roasted, or juiced to add B6 to your diet.
Winter Squash
Varieties like acorn and butternut squash are excellent sources of B6, along with Vitamins A and C. One cup of baked acorn squash provides a significant amount of the vitamin. These hearty vegetables can be roasted, pureed into soups, or added to stews.

Tips for maximizing B6 intake
Since Vitamin B6 is water-soluble, it can be lost during cooking. The method of preparation can significantly impact the amount of B6 that remains in your food.
- Steam instead of boil: Steaming vegetables is a better method than boiling to preserve water-soluble vitamins like B6. If you do boil, use the leftover liquid in soups or sauces.
- Eat raw: Many B6-rich vegetables, such as bell peppers and carrots, can be eaten raw, which is the best way to preserve all nutrients.
- Bake with skin on: For potatoes and sweet potatoes, baking with the skin on helps retain both B6 and fiber.
- Roast or sauté: Roasting and sautéing with a minimal amount of oil can help maintain more nutrients than boiling.
Integrating B6-rich vegetables into your diet
Integrating these vegetables into your meals is easy and delicious. Here are a few suggestions:
- Breakfast: Add a handful of spinach to an omelet or smoothie. Slice some avocado or bell peppers to top a breakfast burrito.
- Lunch: Create a large salad with a base of spinach and top it with chickpeas, sliced carrots, and bell peppers. Add some mashed avocado for a creamy texture.
- Dinner: Roast a medley of sweet potatoes, carrots, and winter squash with herbs and olive oil. Use chickpeas in curries or chili.
- Snacks: Enjoy raw carrots and bell peppers with a side of hummus. Roasted chickpeas make a crunchy, protein-packed snack.
