Why a Plant-Based Diet Makes Sense—Both Nutritionally and Spiritually

From the wisdom of our grandmothers to the pages of Scripture, the benefits of a plant-based diet have long been recognized. But did you know that modern science backs up this age-old wisdom? In this article, we’ll look at how plant-based eating supports health, reduces disease risk, and even reflects God’s original design for nourishment.

It turns out our mothers and grandmothers were on to something when they told us to eat our vegetables. That timeless advice is now backed by modern science, which shows that a diet rich in fruits, vegetables, whole grains, legumes, and other plant-based foods can significantly lower the risk of chronic illnesses such as heart disease, type 2 diabetes, certain cancers, and high blood pressure.

Healthy foods

One of the reasons plant-based eating is so powerful is its natural ability to reduce inflammation. Plants are loaded with fiber, antioxidants, and phytochemicals that support the body’s healing and defense systems. Unlike animal products, plant foods contain zero cholesterol and much lower levels of saturated fat—two major contributors to inflammation and disease. The fiber found in plants also plays a key role in promoting a healthy gut by feeding beneficial bacteria, which in turn support immune health and overall wellness.

Protein and calcium

Many people are surprised to learn that plants provide all the protein and calcium we need. Just look at some of the largest animals on the planet—elephants, bison, giraffes, and moose. These powerful herbivores build massive strength and bone density entirely from plants. If it’s enough to sustain them, surely it’s enough for us.

What the Bible demonstrates

The idea of eating plant-based also has strong spiritual roots. According to Genesis, in the Garden of Eden, before sin entered the world, there was no death—meaning all creatures, including humans, were plant-eaters. Scripture paints a similar picture of the future, describing a restored creation where there will once again be no more death. Even the story of Daniel highlights the benefits of a simple, plant-based diet chosen in devotion to God.

For me, Genesis and Revelation serve as bookends—both pointing to a world where life is sustained by plants. And in the time we’re given between those two sacred moments, God grants us free will in our choices. As we await His return, I want to care for the body He’s given me by returning to the foods He first declared good.

As 1 Corinthians 6:19-20 reminds us, “Do you not know that your bodies are temples of the Holy Spirit, who is in you, whom you have received from God? You are not your own; you were bought at a price. Therefore, honor God with your bodies.”

Choosing to eat in a way that nourishes and honors the body is just one way to reflect our faith in everyday life.
