A healthy diet doesn’t require hours of prep or fancy cooking skills. Food can bring joy and comfort as well as nourishment, and healthy eating works best when it’s flexible and shaped to your lifestyle. Check out these tips to help you adopt practical habits you can put on repeat. 

Healthy eating 101

In a nutshell, the healthiest diets incorporate fruits, veggies, beans, lentils, and whole grains while limiting red and processed meats, salt, unhealthy fats, added sugars, and refined carbs.

Make one or two changes at a time

A healthy dietary pattern can benefit everyone, regardless of age, race, ethnicity, or health. But a healthy diet doesn’t mean every plate is perfect. Start by making one or two healthy changes at a time.

Start with the basics

For a 2,000-calorie diet, aim for 2 1/4 cups of veggies (a mix of dark green, red, and orange veggies, plus beans, peas, and lentils) and 2 cups of fruit (especially whole fruit) per day.

In addition, try to increase your intake of whole grains like whole-wheat bread or pasta, brown rice, quinoa, and corn tortillas, and decrease your intake of refined grains like white bread or pasta and tortillas made from refined flour.

Let legumes do more work  

Already-cooked beans, lentils, chickpeas, and split peas are superstars. They’re a solid source of fiber (about 5 to 8 grams per half cup) and plant protein (about 8 grams per half cup), and they're packed with other nutrients (potassium, magnesium, folate, zinc, and iron!). Plus, producing a serving of beans releases far fewer greenhouse gas emissions than producing a serving of animal proteins like dairy, meat, or poultry.

Since they’re ready in minutes, think of already-cooked beans as nature’s fast food. Toss them into salads, soups, and stews, mash them onto toast, fold them into tacos and quesadillas, or serve them atop a grain bowl and alongside breakfast with eggs and avocado. 

Embrace frozen veggies and fruits

Frozen veggies and fruits are convenient (try frozen artichoke hearts!), last longer, and help eliminate unnecessary food waste. And since many, like frozen cherries, have been washed, cleaned, stemmed, chopped, etc., they save valuable time in meal preparation.  

They’re also frozen at peak ripeness, preserving their nutritional content. Plus, they’re an affordable way to eat more produce. For example, frozen berries are just as nutritious and much more affordable than fresh berries.  

So, keep a few bags of frozen fruit and veggies (even beans!) on hand as an easy way to add nutrients and flavor with very little extra work.

Cut salt without losing flavor 

Many people eat more salt than health authorities recommend. While a small amount of sodium is safe and necessary for health, eating excessive amounts over time can cause high blood pressure, or hypertension, increasing the risk of heart attacks and strokes.

But cutting back isn’t easy when some foods have far more salt than you might expect. Restaurant foods are particularly high in sodium, as are prepared foods like pizza, sandwiches, sauces, soups, and frozen dishes.

So, cook at home when possible. And use herbs, spices, dips and salsas, or our favorite timesaving toppings to add fabulous flavor to your cooking. Plus, you can stretch saltier canned sauces to reduce sodium per serving. 

Limit saturated fat 

Evidence shows that saturated fat raises LDL (“bad”) cholesterol and that LDL is a direct cause of heart disease. The evidence also shows that you can slash heart disease risk by replacing saturated fats with polyunsaturated fats, like those in nuts, seeds, and vegetable oils. (Replacing saturated fats with refined carbs or trans fats won’t lower heart disease risk.)  

So, start by making small swaps with big impact. Instead of butter, beef tallow, coconut oil, and palm oil, opt instead for oils low in saturated fat. And try peanut butter instead of butter on toast, and chicken or tofu instead of beef. 

Reduce sugar in everyday eating

Sugary drinks contribute to type 2 diabetes and heart disease—in part by leading to weight gain—and are linked to a higher risk of tooth decay. And added sugars can sneak into foods or beverages like flavored oatmeal, cereal, yogurt, sauces, and sugar-sweetened drinks, where they add “empty calories” without vitamins, minerals, or fiber. But you can make simple swaps that keep food enjoyable while cutting out unnecessary added sugars. For example, make sparkling water or unsweetened tea your go-to drinks, and choose plain oatmeal and low-sugar cereals.  

Build simple meals with a simple formula 

Healthy eating habits are easier to adopt when you think in parts: at least one veggie, a healthy protein (like beans, tofu, seafood, or poultry), a whole grain, and a flavorful sauce or topping.

By building simple meals using this formula, you build healthy habits without it feeling like homework. Try a hearty bowl with brown rice, black beans, bell peppers, frozen corn, salsa, and avocado. Or pair whole-wheat toast with hummus, sliced tomato, and an egg.

Bonus tip: Make better choices easy 

Healthy habits can be easier to adopt when the healthier choice is easy to make. Organize your kitchen so that the healthier choices are more convenient than less healthy ones. Keep unrefrigerated fruits and veggies on the counter, store refrigerated produce at eye level in the fridge, and place sparkling water or unsweetened beverages where they’re easy to grab. After all, the best routines have to withstand tired nights and busy schedules!
