10 Superfoods to Boost Performance, Health and Fitness

Nutrition is the base of all performance. Make sure yours is on point by bringing these 10 Superfoods into your diet & improve all round wellbeing & Crossfit performances.

These Superfoods have been chosen to help you maximise your health, fitness, recovery and performance.


At some point, it simply won’t matter how talented you are, how much time and effort you put into sweating at the gym, programming your workouts and analyzing the weaknesses in your training if you don’t have the nutritional side covered as well.


It gives your body the necessary tools to grow stronger, replenish itself and go the extra mile in all of your daily tasks.

So once you’ve got the basics of your Crossfit nutrition and clean eating covered, let’s talk about the benefits you can reap from adding so-called superfoods, meaning foods with an unusually high amount of important nutrients. Nutrients you, as an athlete, need in abundance.

‘Fancy name and hype aside, superfoods don’t have to be exotic or expensive – you’ll be surprised how many of these multi-talents you’re already eating.’

So here’s a list of the Superfoods that have the most benefits for CrossFit Athletes.


This beverage isn’t only good for hydration levels (and making you feel like you’re on a miniature vacation). Coconut water is the perfect solution to get back on track after a tough WOD:

Like a primal, healthy version of Gatorade, it will give back the electrolytes you lost sweating. The natural coconut sugar is a great way to quickly replenish the glycogen (= energy) deposits in your muscles, paving the way for efficient muscle recovery and growth.

Ever wondered why the Crossfit Dottirs are so successful?

It might be because of a special sort of Icelandic dairy, Skyr. Made from four times the amount of skimmed milk used in yoghurt, it packs a huge amount of calcium and proteins, with next to no carbohydrates and fat, which makes it a perfect fit to hit your protein goals.

As an athlete, you require a lot more anti-oxidants than the sedentary population. Berries and Cherries provide them in abundance, while also catering to your sweet-tooth in a clean way.

Cherries are especially great if you’re working on your endurance: Studies have shown that endurance athletes that drink cherry juice recover more quickly and measurably increase their performance. Way to improve those cardio-WODs!

A pseudo-grain that is actually a seed, Quinoa packs both a decent amount of proteins and complex carbohydrates, as well as essential amino acids, making it a perfect fuel for your body. Its use in sports nutrition is said to reach back all the way to the ancient INCA civilization and their famous warriors, which is not surprising if you look at its further benefits:

  • manganese
  • magnesium
  • iron
  • zinc
  • potassium
  • calcium

All hide in these tiny seeds that can perfectly replace the wheat in your diet.

Made from green tea and usually found as a powder, Matcha is like the Hulk of the superfood family.

Feeling fatigued? Matcha boosts your energy level with a good amount of caffeine. It also contains iron, a mineral that especially athletic females need to maintain their vital functions and stay active. Additionally, it offers tons of important vitamins, calcium for your bones -strength and anti-oxidants to speed up your recovery. And the biggest plus for your six-pack ambitions: catechine, which studies have shown to speed up your metabolism and strengthen the immune system.

Whether you eat them (Sauerkraut; Kimchi) or drink them (Kefir, Kombucha): Fermented foods have a lot more to offer than the fact that you can practically keep them in the fridge forever.

The probiotic bacteria they contain help the balance in your digestive system, helping your stomach get the most nutrients and vitamins from all of the other foods you eat. As an athlete, you’ll be able to digest the ridiculous amounts of food you sometimes eat, without having to compromise on the nutrient absorption. (This also means less supplements.)

The superstar in this group is kale, but other leafy greens like spinach are just as good at living up to their healthy image.

Aside from the fact that they’re a low-calorie staple with loads of different minerals, they are also a fantastic source of folate, which is the natural form of folidic acid. This is a key ingredient in helping the body break down proteins and create new ones from the amino acids (hello, muscles!) and also forming new blood cells and DNA.
