The Year of the Plant? The Benefits of a Plant-Based Diet

Around 50% of adults in the United States intend to start 2025 with an improved diet. Some are trying specific approaches such as keto or low/zero carbs, and others are simply consuming fewer calories. However, research has shown that a plant-based diet is among the most effective means for losing weight and keeping it off. For older adults, a primarily plant-based diet also offers other significant health advantages including improved disease prevention, and better mobility and cognitive health.

Healthy Body
Rich in fiber, antioxidants, and phytonutrients, plant-based diets help in the fight against chronic conditions such as heart disease and diabetes. A study published in the Journal of the American Heart Association found that adults consuming mostly plant-based foods had a 16% lower risk of cardiovascular disease, and diets focused on fruits, vegetables, whole grains, and legumes help maintain better blood pressure and cholesterol levels.

Plant-based diets can also enhance mobility by supporting joint and bone health. Many of these foods, such as leafy greens, nuts, and seeds, are rich in calcium, magnesium, and anti-inflammatory compounds that help to reduce arthritis symptoms and strengthen bones. 

As noted in a recent Amevida blog post, strength training is critical to slow the natural loss of muscle mass as we age, and proper protein intake is crucial to ensure you get the most out of your workouts, as well as supporting recovery between sessions. As providers of protein, plants also offer benefits that animal-based sources do not. These include additional dietary fiber, polyphenols, and unsaturated fats but, crucially, not counterproductive nutrients such as high amounts of sodium that can be found in meat.

Healthy Mind
Dietary patterns emphasizing plants, such as the Mediterranean or MIND diets, have also been linked to better cognitive health. A recent Columbia University study indicated a connection between adhering to a MIND diet and slower cognitive aging. These diets, rich in antioxidants from berries, leafy greens, and omega-3s from nuts, reduce inflammation and oxidative stress, which research shows are contributing factors to conditions like Alzheimers and other progressive dementias.

How to Start
To transition to a plant-based diet, start small by replacing one meal a day with a plant-based option, such as oatmeal for breakfast or a vegetable-only stir-fry for dinner. Focus on variety by incorporating a range of whole grains, legumes, vegetables, fruits, and nuts to ensure your meals are diverse and keep you interested. To maintain nutritional balance and avoid deficiencies consider taking supplements (at least at the beginning) for essential nutrients like vitamin B12, calcium, and omega-3s. These small, practical steps can make adopting a plant-based lifestyle both accessible and sustainable for anyone looking to implement new eating habits this year.
