At the Root of It All: Plant-Based Diets and the Importance of Eating Seasonally

Updated: May 10

Benefits of a plant-based diet

Many chronic diseases can be controlled, reduced, or even reversed by adopting a whole-food, plant-based diet! These are some pretty big claims, but they’re backed by excellent scientific evidence collected from numerous studies on the subject.


The China Study– a book that I mentioned in my previous plant-based blog, explores the link between animal products and chronic illness and is noted to be the most comprehensive study of nutrition ever–showcases impressive findings regarding the positive effects a plant-based diet has on heart-related problems, cancer, diabetes, and brain function.


Heart-related issues

A plant-based diet is the ONLY diet proven to prevent and even reverse heart disease! While there are varying degrees of plant-based diets (vegan vs. vegetarian) studies have shown that even those who follow a vegetarian diet with no animal products except for dairy and/or eggs are at lower risk for coronary heart disease and usually have lower cholesterol than meat-eaters.


Cancer

It’s true that some people may be genetically predisposed to cancer, but diet, lifestyle, and environmental factors also contribute to the likelihood of developing cancer. Luckily, the latter three are all within your control. Research has shown that plant-based diets positively affect survival for individuals with breast cancer, colon cancer, prostate cancer, and skin cancer (melanoma).


Individuals that eat a vegetarian diet are typically at a lower risk for developing gastrointestinal and colorectal cancers too. The American Cancer Society even recommends that cancer survivors follow plant-based diets that are high in fruits, vegetables, and unrefined grains and low in red and processed meats, refined grains, and sugars.


Diabetes

The typical recommended diabetic diet limits carbohydrates and caloric intake, but a study conducted by the PCRM proved that a plant-based diet is actually three times more effective to control your body’s blood sugar, largely due to the low fat intake. I often have conversations with my clients about different kinds of fats and which ones are healthy for their unique body.


Other research has yielded results that show vegans and vegetarians have a ~34-50% lower risk of developing type 2 diabetes than their animal product consuming counterparts.


Mental health and brain cognition

The key ingredient here is antioxidants, higher levels of which have been linked to reduced risk of depression, lower suicide rates, and slowed progression of Alzheimer’s. A comparative analysis which included results of nine different studies concluded that those who ate more fruits and vegetables had 20% less risk of developing cognitive impairment or dementia.


Higher levels of antioxidants in the blood from plant sources have been associated with a significantly lower risk of depression and lower suicide rates. In both cross-sectional and interventional studies, vegetarians showed fewer symptoms of depression, anxiety, stress, and mood disturbance than omnivores.


Gut health

In this study, plant-based diets were found to be protective against cancers of the digestive system, with no significant differences between different types of cancer.


All plant-based diets are not created equal

These results are astounding and truly show the power behind functional nutrition and whole health solutions. But we have to remember that not all plant-based diets are created equal! There is such a thing as “junk food vegetarians”—vegetarians who eat pizza, processed foods and Doritos—and that’s not healthy either.


Avoid sugary drinks, fruit juices, refined grains, processed/packaged food like substances, and processed dairy when beginning a plant-based diet and focus on consuming nutrient dense vegetables, fruits, whole grains, legumes, and nuts. Try eating seasonally if you’re unsure of where to start on your plant-based journey!


Seasonal eating

Eating with the seasons is the best way to get the most nutrient-dense, flavorful fruits and veggies. Produce harvested at its peak has the highest concentration of vitamins, minerals, and antioxidants, so the fresher, the better. And thanks to their abundance, seasonal produce is typically more affordable too!


Regional produce yields vary, so check with your local farmer or grocer, but here’s what’s in season here in the Northeast:


Note: If you can’t access seasonal produce, frozen fruits and vegetables are a better alternative than canned, as they require less processing and retain far more nutrients.
