"Eat healthier."
What sounds like simple, straightforward advice can quickly turn into a flood of conflicting recommendations, leading to decision paralysis, and maybe another bag of chips.
From changing nutrition advice to concerns about food safety, knowing where to start can feel overwhelming. According to Samuel Mathis, MD, a family medicine physician at The University of Texas Medical Branch (UTMB Health), one of the most effective approaches is also one of the simplest: Eat more plants.
A plant-based diet focuses on foods that come from plants, including vegetables, fruits, whole grains, legumes, nuts, and seeds. It doesn't necessarily mean eliminating meat or animal products altogether. Instead, it emphasizes making plant foods the foundation of most meals.
"For individuals who are looking to try to eat healthier, the best thing I can recommend is start small, make gradual changes, and find a way of eating that you can actually live with," Mathis said. "Instead of thinking of it as a diet, make it a lifestyle that feels sustainable."
Why plants matter
Research consistently shows that diets rich in plant foods can support heart health, improve blood sugar management, promote healthy weight maintenance, and reduce the risk of several chronic diseases.
Plant-forward eating also aligns closely with the lifestyle habits observed in the world's Blue Zones, regions where people routinely live longer, healthier lives. While each Blue Zone has its own cultural traditions, they share several common dietary patterns, including eating mostly whole, plant-based foods and limiting those that are highly processed.
Rather than focusing on strict rules or deprivation, Blue Zones principles emphasize sustainable habits that can be maintained over the long term.
"Everything in moderation, including moderation," Mathis said. "Even people who live in Blue Zones have a slice of cake every once in a while. They have a treat."
That emphasis on balance is one reason plant-based eating can be easier to adopt and maintain than highly restrictive diets.
Getting started
For those interested in incorporating more plant foods into their routine, experts recommend starting with manageable changes:
- Add a serving of vegetables to lunch and dinner.
- Replace refined grains with whole grains such as brown rice or quinoa.
- Include beans, lentils, or peas several times each week.
- Snack on fruit, nuts, or seeds instead of highly processed foods.
- Experiment with meatless meals one or two days a week.
The goal isn't perfection. It's building healthier habits that can last for years.
Don't forget food safety
As more people incorporate fresh produce into their diets, food safety remains an important consideration. Leafy greens and other produce are among the foods most commonly linked to foodborne illness outbreaks because they are often eaten raw.
"Most of the issues we've seen with some of the Cyclospora outbreaks have been linked to a specific brand, but that brand also supplies a lot of produce to restaurants and fast-food establishments," Mathis said. "That may be a reason why we're seeing this happen."
According to Mathis, one of the most important food safety practices is washing produce before eating it, even when packaging labels it as "prewashed," "triple-washed" or "ready-to-eat." Rinsing fruits and vegetables under cool running water can help remove dirt and reduce potential contaminants.
Leafy greens deserve special attention because their folds and layers can trap dirt and debris. For people who regularly prepare salads at home, a salad spinner can be a useful tool and especially helpful for bagged salad mixes that contain smaller ingredients such as shredded carrots and cabbage.
For people at increased risk of serious foodborne illness, cooking vegetables may provide an additional layer of protection.
Organic, conventional, and hydroponic options
Consumers are often unsure whether organic produce is necessary. Mathis recommends a practical approach.
Some fruits and vegetables naturally have lower pesticide exposure because they are protected by thick peels or rinds. Others may be worth purchasing organic when possible.
"The Dirty Dozen are the plants that you may want to consider buying organic because of their higher potential pesticide exposure," Mathis said.
Resources such as the Environmental Working Group's annual Dirty Dozen and Clean Fifteen lists can help consumers make informed choices while staying within budget.
Some individuals, particularly those with weakened immune systems, may also be interested in hydroponically grown produce.
"Hydroponics use a very nutrient-rich water to help create and grow plants," Mathis said. "They work really well indoors. And if you're growing them yourself, then it also helps you control any pesticides that are being used."
Mathis noted that growing plants at home may provide benefits beyond nutrition.
"The added benefit of hydroponics is that it adds more greenery to your space," he said. "There is some really good evidence that having plants indoors can provide mental health benefits for many patients."
A lifestyle, not a diet
Ultimately, Mathis says the most effective eating pattern is one you can maintain over time. Whether it's adding more vegetables to each meal, trying a meatless recipe, or growing herbs at home, small changes can lead to meaningful health benefits.
