With the right changes, your salad can be a nutrition powerhouse rich in minerals, phytonutrients and fiber.

Popular folklore dates the invention of the humble Caesar salad to the early 1920s. Approximately 90 years later, it’s time for you to move beyond this salad bar staple. Swap out the romaine lettuce for some exotic greens, throw in a few out-of-the-norm toppings — croutons are the definition of salad drudgery — and show the vegetable world who’s boss.

Start with anything but lettuce. There’s nothing wrong with lettuce, which can be a rich source of vitamins — two cups of romaine lettuce provides more than 150% of your RDA for vitamin A — and fiber. But non-traditional greens can add yet another layer of flavor complexities and nutrients. For example, you could try:

• Spinach, which is high in calcium
• Shepherd’s purse, a member of the cruciferous family that’s high in carotenoids and glucosinolates
• Purslane, a source of more healthy omega-3 fats compared to every other leafy vegetable
• Dandelion greens, which are endorsed by French chefs for their unique flavor but also boast high levels of electrolytes like potassium

Add some heavy proteins. This, combined with the fiber in the greens, turns your salad into a legit meal that keeps you feeling full and happy for a long time. For carnivores, choose lean meats such as tuna, sirloin steak or chicken breasts. For plant lovers, try dicing up some marinated tofu or adding a can or two of your favorite beans.

Toss out those fancy and fattening bottled salad dressings. A single two tablespoon serving of your average ranch dressing can often net you 300 to 500 calories — and many people douse their salads with more than just a couple tablespoons. Instead, mix a lightweight homemade dressing using healthy ingredients like olive oil, balsamic vinegar, mustard or lemon juice, and herbs such as oregano, pepper and basil. Too much trouble? A second-best option: Lighten your commercial salad dressing by blending the dressing with an equal amount of olive oil.

Add color — as much as you can manage. Chase a rainbow of colors harder than a unicorn at a rave. In general, foods that are colorful are richer in phytonutrients that have a litany of health benefits, such as fighting cancer. Example options include yellow bell peppers, red onions, radishes and beets.

Go nutty. Nuts add crunch and new textures to your salad while also boosting its fiber and protein quotient. Even better, nuts are a top source of heart-healthy fatty acids. For even more flavors, roast them before tossing them into your salad.

Sprinkle on the seeds. Hemp seeds and flax seeds are optimal sources of protein, add a  layer of visual interest and also increase your intake of fiber and omega-3s.

Vitamin C

One thousand milligrams of vitamin C, split into two 500 mg doses per day, can help battle chronic fatigue and increase your leg muscles’ endurance. This may be in part to the vitamin’s effects on adrenaline and cortisol in your muscles, as well as its anti-inflammatory effects. In a 2001 study published in the International Journal of Sports Medicine, researchers noted that vitamin C supplementation in ultramarathon runners helped increase the presence of anti-inflammatory substances in the runners, as well as reduced stress hormones — all factors that may lead to faster recuperation and increased energy.

Vitamin B12

Vitamin B12 helps with the conversion process of fat and protein into energy. Thus, it’s often used by athletes to increase energy levels, enhance performance and build endurance. The U.S. Office of Dietary Supplements warns that a deficiency in this vitamin — the average adult needs 2.4 mcg a day — can directly lead to weakness and fatigue, both in your legs and the rest of your body.

Vitamin D

When you turn your face up toward the golden sun, you get not only a dose of warmth, but also a boost of vitamin D. For runners, vitamin D can help reduce muscle pain and can also help battle chronic fatigue, reports Men’s Fitness magazine. Other benefits for your leg muscles: it may help reduce inflammation — perfect after a strenuous leg workout — and boosts immunity. Additionally, a 2009 study in the Medicine & Science in Sports & Exercise medical journal notes that vitamin D improves general athletic performance by increasing the number and size of muscle fibers in your legs and elsewhere. The average adult needs 600 IU of this vitamin daily.

Pantothenic Acid

Pantothenic acid, also known as vitamin B5, is critical for your energy production in your legs and the rest of your body. For this reason, it’s been used to treat everything from fatigue to muscle cramps. Many runners and athletes don’t get enough B vitamins in general; aim for 5 to 10 mg of vitamin B5 a day.
