Why Celebs Swear By These Superfoods

If you haven't heard of blue-green algae (aka spirulina) as a food source, you are not alone. It definitely isn't the most mainstream superfood out there, but in a Twitter post Kourtney Kardashian shares that "It's the easiest way to get your nutrients." On her website Poosh, she explains that the algae supplement is not only rich in minerals and protein but also helps keep her mind feeling sharp. Plus, since it comes as a powder it's easy to incorporate into drinks.

Eat This, Not That got the full list of ingredients for Kardashian's daily smoothie, which of course includes this impressive supplement. If you're looking for a power-packed morning smoothie, simply blend up a whole avocado, one cup of organic plant-based milk, one scoop of vanilla protein powder, a quarter teaspoon of MCT oil, some bone broth powder, and blue-green algae. To add some sweetness, Kourtney opts for honey or stevia if she's following a keto regimen.

English model and actress Rosie Huntington-Whiteley starts her day with a superfood that is becoming more and more mainstream: a freshly made green drink. She shares on Twitter that green juices are a "great way to start the day." Meanwhile, in an interview with Elle, she made it clear that when it comes to the taste of her green smoothies, she isn't especially picky. Listing ingredients like bananas, almond butter, apple, spinach, and kale, she confessed that anything healthy, "whether it tastes good or not," goes in.

According to Consumer Reports, leafy greens are at the top of the list of healthy foods. If you're struggling to eat them in a salad or cooked in dishes, drinking them is a fine alternative in an otherwise balanced diet. In fact, WebMD states that green smoothies are a great way to incorporate leafy greens into your diet. So next time you're blending up a smoothie, throw in some kale and spinach. Or, opt for a fresh green juice instead of the usual latte.

To stay hydrated, American singer-songwriter and actress Madonna apparently swears by coconut water. Pop Sugar reports that she drank it every day during her Sticky & Sweet tour from 2008 to 2009. We can believe it, since she also contributed millions to the coconut water brand Vita Coco, and was chosen to be part of the pool of investors as a brand loyalist who drinks the beverage regularly, per her website.

According to the Cleveland Clinic, coconut water aids in hydration, which benefits your body's functioning. Nutritionally, it is high in potassium and low in calories, with zero fat or cholesterol content. It can also help with kidney stone prevention and may help fight acne thanks to its antimicrobial properties. You can drink coconut water straight, and shelf-stable brands make a great on-the-go option even on hot days. Add it to smoothies too, or use it to infuse some sweetness into your green drinks if you've gone a little heavy on the kale.

How does Mexican-American actress and producer Salma Hayek manage to always look youthful and glowing? Apparently, she thanks bone broth for helping to keep her young, per an interview with People. Bone broth has become more prominent in recent years, with many celebrities opting to have it for breakfast instead of the usual cup of coffee.

According to Healthline, the broth is rich in bone-strengthening minerals, as well as vitamins, amino acids, and essential fatty acids. Research suggests it might support healthy digestion, fight inflammation, and improve joint health. Health.com even states that bone broth might — as Salma suspects — make skin appear fuller and plumper. If you balk at the idea of having bone broth straight, you can also add it to soups and even smoothies. Or, make it a habit to regularly make your own chicken soup using a whole chicken — bones and all.

When it comes to turmeric, supermodel Jourdan Dunn is a fan, telling Glamour that of all the spices, it is her favorite. She lists it as a must-have spice in her diet (via Marie Claire) and shares with StyleCaster that turmeric is one of the three ingredients you will always find in her kitchen. According to the National Institutes of Health, turmeric has a variety of interesting biological activities, but they are difficult to study for potential side effects. Even just as a tasty addition to curries, WebMD states that turmeric might positively impact cholesterol levels, help with joint pain, and possibly help ease the symptoms of irritable bowel syndrome.

Dunn doesn't stop at using it in her cooking but adds it to her beauty routine as well. Shape reports that she mixes the bright yellow powder into her homemade face mask along with yogurt, honey, lemon juice. This regimen isn't for all skin types so be sure to investigate before trying it out yourself. Ultimately, the best way to reap the benefits of turmeric is by consuming it as a whole food rather than a supplement.

American actress Jennifer Garner loves flaxseeds, which she adds to her #BeWellSmoothie developed by Kelly LeVeque, a holistic nutritionist and health coach (via Instagram). According to Medical News Today, flaxseeds are a functional food loaded with healthy omega-3 fatty acids, protein, antioxidants, and fiber. What's more, a 2014 study published in the Journal of Food Science and Technology reported that flaxseed protein may protect against coronary heart disease, kidney disease, and cancer.

If you do not want to add flaxseeds to your smoothies like Garner but still want to reap their benefits, be sure to grind them up first, as recommended by Healthline. Their tough outer hull prevents them from breaking down in your digestive tract, essentially eliminating the positive effects. Ground flaxseeds can be also stirred into oatmeal, sprinkled on fresh fruit, or added to homemade cracker batter. Because ground flax has a short shelf life, it is best to store it in the refrigerator.

The Kardashian sisters are no strangers to unfamiliar superfoods you might not have heard of before. While Kourtney swears by blue-green algae, American media personality, socialite, and businesswoman Kim Kardashian loves to add sea moss to her smoothie, a fact she divulged during a Twitter Q&A . She also shared a picture of her sea moss smoothie and avocado toast breakfast on her Instagram stories (which was promptly discussed by sources including Shape). Sea moss can be hard to dissolve in a blender and it is best used after a thorough soak in freshwater. But as it is relatively tasteless, it can be added to most smoothies without you knowing the difference

WebMD states that while the research on sea moss is still in its infancy, the seaweed could provide benefits in the prevention of Parkinson's disease and may boost the immune system. It also contains vitamin B2, B12, calcium, chromium, magnesium, and zinc. According to Healthline, sea moss is a natural source of iodine, a micronutrient necessary for thyroid health. Plus it's full of antioxidants which protect the body against disease-causing oxidative damage.
