Greens, oranges, reds, purples, yellows...you get the picture. Eating the rainbow will supply your body with a range of disease-fighting phytonutrients, and will naturally fill you up to help you cut back on unhealthy foods, says Dr. Lipman. Plus, most adults struggle with getting the recommended five servings a day (though some say seven servings). A worldwide study in 2014 found 58 to 88% of adults don't hit that mark. Aiming for a diverse intake of produce from all colors of the rainbow will help you boost your intake. In another study, adults who were offered a variety of vegetables ate more of them without increasing the calories at the meal, found a 2012 study.
Even more important than shopping for healthy foods: actually eating them. When you get home from the store or farmer's market, bounty of fruits and veggies in tow, wash and chop them right away and store in a pretty glass container in your fridge. "Studies show that spending more time on food prep is linked to better eating habits," says Dr. Lipman. It's all about convenience—if they're ready for you, you'll grab them in a pinch. If not? It's chips and dip time. You can also do this with other foods, like making a batch of quinoa for the week or roasting a bunch of veggies to throw together for quick lunches.
Opt for recipes with variety. Try to get a variety of vegetables on your plate, such as dark leafy greens, beets, artichokes, onions, carrots, and cucumbers. Add cooked chickpeas, avocado, brown rice, baked sweet potato, hemp seeds, extra-virgin olive oil, and other foods rich in protein, fiber, and fat. Better yet, look for recipes that combine a variety of plant-based ingredients like Sweet Potato and Red Cabbage Slaw.
Eating a healthy diet doesn’t have to be overly complicated. While some specific foods or nutrients have been shown to have a beneficial effect on mood, it’s your overall dietary pattern that is most important. The cornerstone of a healthy diet pattern should be to replace processed food with real food whenever possible. Eating food that is as close as possible to the way nature made it can make a huge difference to the way you think, look, and feel.
But the psychological or spiritual effect can't be discounted, says Dillard. "People love the idea of cleansing, of purification rituals, going to the Ganges, to the spa. It has powerful psychological, religious, spiritual meaning. That has its own positive effect on health. But we need to separate that from saying this is science or good medicine."
