The evolution between eater and eaten might answer the long-held question about why humans live longer, healthier lives on traditional diets. As researchers work to unravel the complexities of the interactions of the foods we eat, try these combinations, the most powerful food synergies currently known to science.

TOMATOES AND AVOCADOS 

Tomatoes are rich in lycopene, a pigment-rich antioxidant known as a carotenoid, which reduces cancer risk and cardiovascular disease. Fats make carotenoids more bioavailable, a fact that makes a strong case for adding tomatoes to your guacamole. 

“This also has a Mediterranean cultural tie-in,” says registered dietitian Susan Bowerman of California Polytechnic State University. “The lycopene in tomato products such as pasta sauce is better absorbed when some fat (e.g., olive oil) is present than if the sauce were made fat free.” This may also explain why we love olive oil drizzled over fresh tomatoes. 

And when it comes to salads, don’t choose low-fat dressings. A recent Ohio State University study showed that salads eaten with full-fat dressings help with the absorption of another carotenoid called lutein, which is found in green leafy vegetables and has been shown to benefit vision. If you don’t like heavy salad dressing, sprinkle walnuts, pistachios, or grated cheese over your greens.

BLUEBERRIES AND GRAPES

“Eating a variety of fruit together provides more health benefits than eating one fruit alone,” says Bowerman. “Studies have shown that the antioxidant effects of consuming a combination of fruits are more than additive but synergistic.” 

In fact, a study published in the Journal of Nutrition by Rui Hai Liu, Ph.D., from Cornell University’s department of food science, looked at the antioxidant capacity of various fruits individually (apples, oranges, blueberries, grapes) versus the same amount of a mixture of fruits, and found that the mix had a greater antioxidant response. According to the study, this effect explains why “no single antioxidant can replace the combination of natural phytochemicals in fruits and vegetables.” 

The author also recommends eating five to 10 servings of a variety of fruits and vegetables daily to reduce disease risks, as opposed to relying on expensive dietary supplements for these compounds. “There are a huge number of compounds yet to be identified,” adds Jacobs. 

LEMON AND KALE

“Vitamin C helps make plant-based iron more absorbable,” says nutritionist Stacy Kennedy of the Dana Farber Cancer Institute. It actually converts much of the plant-based iron into a form that’s similar to what’s found in fish and red meats. (Iron carries oxygen to red blood cells, staving off muscle fatigue.) 

Kennedy suggests getting your vitamin C from citrus fruits, leafy green vegetables, strawberries, tomatoes, bell peppers, and broccoli, and getting plant-based iron from leeks, beet greens, kale, spinach, mustard greens, Swiss chard, and fortified cereals. 

So whether you’re sautéing dark greens or making a salad, be sure to include a squeeze of citrus. You’ll increase your immunity and muscle strength with more punch than by eating these foods separately.

RED MEAT AND ROSEMARY

Grilling over an open flame produces nasty carcinogens, but if you get a little more experimental with your spices, you can temper the cancer-causing effects of the charred flesh. 

The herb rosemary, which mixes well with all kinds of grilled foods and contains the antioxidants rosmarinic acid and carnosic acid, was recently shown in a Kansas State University study to lower the amount of the cancer-causing heterocyclic amines (or HCAs) that appear in the charred meat when you grill at temperatures of 375°F to 400°F. Why? It’s thought that the herb’s antioxidants literally soak up the meat’s dangerous free radicals.

EGGS AND CANTALOUPE

The most popular (and an awfully complete form of) breakfast protein works even better for you when you eat it with the good carbohydrates in your morning cantaloupe. 

According to Kennedy, a very basic food synergy is the concept of eating protein with foods that contain beneficial carbohydrates, which we need for energy. Protein, Kennedy reminds us, slows the absorption of glucose, or sugar, from carbohydrates. 

“This synergy helps by minimizing insulin and blood-sugar spikes, which are followed by a crash, zapping energy. High insulin levels are connected with inflammation, diabetes, cancer, and other diseases. By slowing the absorption of glucose, your body can better read the cues that you are full. This helps prevent everything from overeating to indigestion.” 

So cut as many bad carbs (i.e., anything white, starchy, and sugary) as you want. But when you eat healthful carbs (whole grains, fruit, vegetables), don’t eat them on their own.
