1. Apples: Support Your Gut & Heart
Apples are an easy way to add more fiber and beneficial plant compounds to your diet. They contain both soluble and insoluble fiber, along with polyphenols (plant antioxidants).
One of the most beneficial types of fiber in apples is pectin (soluble plant fiber). Pectin can be fermented by beneficial bacteria in the gut and may also help support healthy cholesterol levels.
Why It Matters for Longevity
A diet rich in fiber and plant-based foods supports digestive, metabolic, and cardiovascular health. Apples are an especially simple way to increase your intake because they’re portable, widely available, and easy to add to meals and snacks. Whenever possible, eat the skin too. Much of an apple’s fiber and beneficial plant compounds are concentrated there.
Simple Actions This Month
Add a sliced apple to oatmeal or Greek yogurt at breakfast.
Pair an apple with natural peanut or almond butter for a more filling snack.
Add chopped apples to fall salads with leafy greens, walnuts, and a simple olive oil dressing.
Choose a whole apple instead of apple juice to get the benefits of its fiber.
2. Sweet Potatoes: Add More Color to Your Plate
Sweet potatoes get their bright orange color from beta-carotene, a plant pigment your body can convert into vitamin A. They’re also a source of fiber, potassium, vitamin C, and vitamin B6. Orange sweet potatoes are particularly rich in beta-carotene, while purple varieties contain anthocyanins (plant antioxidants), another group of beneficial plant compounds.
Why It Matters for Longevity
Colorful vegetables provide a wide range of vitamins, minerals, fiber, and phytochemicals (a beneficial plant compound). Eating a greater variety of plant foods and colors can help create a more nutrient-dense dietary pattern that supports long-term health. Sweet potatoes are an easy fall substitute for more highly processed carbohydrate options, especially when they’re roasted, baked, or boiled rather than loaded with added sugar.
Simple Actions This Month
Roast sweet potato wedges with olive oil and your favorite herbs.
Add diced sweet potatoes to salads, grain bowls, or soups.
Top a baked sweet potato with beans, greens, and Greek yogurt for an easy meal.
Skip the marshmallows and added sugar. Sweet potatoes already have plenty of natural sweetness.
3. Pumpkin: Go Beyond Pumpkin Spice
Pumpkin isn’t just for pie or your morning latte. Pumpkin is a nutrient-dense winter squash that provides carotenoids (plant antioxidants), including beta-carotene (vitamin A precursor), along with fiber and other important nutrients. Its bright orange color is a good reminder of a simple nutrition principle: adding more naturally colorful plant foods can help increase the variety of nutrients and plant compounds in your diet.
Why It Matters for Longevity
Long-term health isn’t built around one “superfood.” It’s built around consistent dietary patterns rich in vegetables, fruits, legumes, whole grains, nuts, seeds, and other minimally processed foods. Pumpkin gives you another easy way to increase the variety of plants in your diet while adding nutrients without relying on highly processed fall foods.
Simple Actions This Month
Add unsweetened pumpkin puree to oatmeal or Greek yogurt with cinnamon.
Blend pumpkin into soups for a creamy texture without heavy cream.
Roast fresh pumpkin or other winter squash as a side dish.
When buying canned pumpkin, look for 100% pumpkin rather than pumpkin pie filling with added sugar.
The Big Picture
Eating for longevity doesn’t require a complicated diet or a list of expensive superfoods. Some of the best choices are simple, seasonal foods you can find at almost any grocery store.
This fall, use the season as an opportunity to add more plants, more color, and more fiber to your meals.
