Hey Powerfoodie, welcome to renskroes.com!

This platform is all about leading a happy, healthy and balanced lifestyle. Improving health is the foundation for everything that you’ll find here. Being healthy is my passion and has been for as long as I can remember. And within the theme of being healthy, nutrition is my focus. This website is home to my favorite Powerfood recipes and blogs about food, as well as articles on exercise, good vibes and beauty. I also share cooking videos, upcoming events, updates and a whole bunch of tips and tricks that are aimed at helping you lead a more conscious and balanced life. I try to provide inspiration where I can – this is what I enjoy the most. Curious about how this – my entire business and this website – came to be? Then read on…

My Story

My youth
My love for healthy living goes way back! My Beppe (grandmother in Frisian) grew up in her father’s bakery/grocery store in a small, Frisian village. The store was eventually taken over by her brother, Uncle Ids. Both were known for the sourdough bread they baked and they sold the tastiest oat cookies in the village. Beppe married my Pake (grandfather in Frisian), who had taken over his father’s farm in Friesland in the 1930s. In the 1960s, an increasing number of farming businesses began to move toward a more industrial agricultural model. Beppe was skeptical of this trend and convinced Pake to move toward organic production. It was a progressive move at the time, but Pake followed her vision. At the end of the 1970s, they stopped farming cattle altogether and produced only vegetables, fruit and herbs.

Their daughter, my Mem (mother in Frisian), went into nursing when she was about 18-years old – she was fascinated by the human body. She discovered that in hospitals, a great deal of attention was devoted to medicine and almost none was devoted to nutrition. This made her very aware of the choices she made. She began learning about the role of nutrition in the progression of certain diseases. She also began her studies to become a nutritionist. It won’t come as a surprise, then, to learn that we ate predominantly plant-based, organic, whole food at home. My parents did the grocery shopping at my uncle’s store and we ate as many vegetables and herbs as possible that we had grown in our own garden. In the cold, winter months, we grew kale, Brussels sprouts, leeks, carrots, endive and potatoes. In the spring and summer, our garden was full of fruit and summer vegetables. We ate dandelion leaves (good for the liver) and nettle (high in iron) and were fed bee pollen, spirulina and seaweed, too.


My website
Based on the story so far, it’s probably a no-brainer that nutrition ended up being a big deal in my life. I started blogging about my love of (healthy!) food and drinks in 2013, when I was still working at an obesity clinic (where I learned about the psychological side of eating). My blogs were well-received. It was so satisfying to be able to help people just a little bit with my tips, tricks and advice and by sharing my own lifestyle with others. 

My own food-coaching practice
Later in 2013, I began my own food-coaching practice, where I spent the next three years coaching so many sweet, satisfied @powerfoodies. Being able to contribute something positive and good in this way meant so much to me. Healthy, balanced eating and the right advice made people happy and I will never forget this experience.

Books 1 to 4
Meanwhile, I launched my first book, Powerfood. The positive feedback poured in: ‘Because of the advice in your book, I’ve started eating more consciously’; ‘I’m finally feeling less bloated’ and ‘Now that I spend more time in the kitchen, I enjoy the food I eat so much more’. More than once, your amazing words brought me to tears. I’m so proud that I was able to help.

So, I continued on, writing a second book (Powerfood – from Friesland to New York, which is not in English). And then a third (Powerfood – On the Go) and a fourth (Powerfood – the Party Edition, not in English)! The beautiful, sweet messages continued to flow, but I also received questions on a regular basis. In my first four books, I focused on sharing recipes, but between the lines, I also shared a bit about my lifestyle, what I believe in and what I stand for. The questions about my lifestyle led me to write my fifth book: Rens – My Lifestyle Guide. 

Book 5
After book one came out, I already had book five on my mind. After book four, there was finally the room to get to work on it. I had the opportunity to calmly and broadly explain what my vision is, where I’m coming from. In book five, I explain the basis, how I see life. I share who I am, that I don’t spend all my time downing ‘superfoods’ (not to be confused with Powerfood) and sipping juices, and that I do stand for so much more than that. A happy and healthy lifestyle is created by finding balance in the areas of nutrition, exercise, relaxation, mindset, what you radiate into the world and how you take care of the world around you. Are you aware of these things on a daily basis? If so, then, to me, you are living a healthy lifestyle. By fully explaining my vision and accompanying lifestyle in my fifth book, I hope to inspire others to live as balanced and conscious a life as possible. And the recipes from my previous books fit nicely into this balanced lifestyle. This last book has made my story more complete than ever and I am so, so proud of it. Hopefully this one will be in English soon! 

Online store: Powerfoodies Market
In June 2018, my partner and I started an online store called Powerfoodies Market. The store sells my own food products (stay tuned!) and goodies. What was the idea behind it? Four years ago, I created my Instagram page @powerfoodies. I wanted to offer a platform on which everyone could share their Powerfood recipes using #powerfoodies and #renskroes. This was a big success. I also noticed that I was starting to receive a lot of questions about where I buy certain (sustainable and high-quality) products, like essential ingredients and kitchen supplies. So, we started this website for everyone who is looking for high-quality, sustainable (tasty) products and wants to know where they came from, accompanied by recipes, information and tips. Running an online store is very different than anything I’ve done before. It requires pure entrepreneurship and requires an enormous amount of time. But it’s worth it! Because every time I send off an envelope with my very own stainless-steel drinking straws (better for the environment) in the mail, it makes me so happy. I’m also super interested in hearing what you think of the Powerfoodies Market. So, have a look and share your impressions with me. I’d love to hear from you.

On this platform, I give you a peek into my lifestyle, with a focus on nutrition. I want to inspire you to become (more) aware of your own choices and your own life. And I hope that in becoming (more) aware, you will act accordingly in the world to create a happy and healthy lifestyle for yourself and for the world around you.

I have formulated seven key factors that I believe contribute to living the happiest and healthiest life possible. I hope they inspire you. And by inspire, I mean really inspire. It isn’t my intention to push you into anything nor do I claim that my ideas are the only way to achieve happiness. These factors should be seen as a sort of toolkit – take what is useful to you and just leave the rest in the box. ; )

1.Good Vibes
Being aware in my life is key, for me! Everything I do, I do with my full attention. Every day. Whether it’s eating or taking care of myself, or others or the planet. Being aware of your thought patterns is, in my opinion, just as important. You can easily convince yourself of something by believing that your negative thoughts are justified. But they usually aren’t. I’ve learned to listen to my thoughts. Just listen. You don’t necessarily have to do anything in response to them – they are just thoughts after all. Sometimes they are true and sometimes they are not. Either way, there are a ton of them every day. What is great about this is that you can choose which ones you react to and which ones you ignore. I try to react to my positive thoughts as much as possible. I believe that you attract into your life whatever you focus on, so why not make it something positive, right? In this way, you’ll create positive vibes and make yourself happier. It works for me, anyway. What also helps me to be positive in life is to dare to be vulnerable, even in response to things that you find difficult. It’s a bit of a paradox, but I believe it’s exactly what you need to achieve what you set out to achieve. It is so important to really see what is and what is not going well and not just stick your head in the sand. I know very well that I don’t do everything perfectly, but thankfully I don’t need to. I feel like crap sometimes, angry or sad. These are all feelings that are allowed to come up. And by acknowledging the more difficult moments, I’m better able to put things into perspective and keep my negative thinking at bay. I allow the feelings to exist, but I choose to focus on the positive in my life and, in this way, a whole bunch of good vibes are created. It’s so great.

2. Relax
If you’re constantly switched ‘ON’, your body will be knocked out of balance. Always being on-call or ready to respond creates a certain amount of stress, which, in turn, affects your body. Because the physical and mental well-being are so closely linked, I think it’s essential to take the time to relax when necessary. This allows me to recharge. I share the ways that I relax in my lifestyle book.

3. Food Philosophy
‘Healthy eating’ is a relative term. I really believe that. There isn’t one, single way to eat healthy. Everybody has different cravings, needs and habits. Moreover, every body is different, which means that everyone’s nutritional needs are different, too. Over the years, I have developed my own vision on food and nutrition. Based on the way I was raised and developments in the food industry, I came up with my own opinion on the issue. I have built upon and updated knowledge I gained growing up, but I always keep in the back of my mind the wisdom that my grandparents and parents shared with me. It doesn’t have to be complicated. It really doesn’t. The purer the food (Powerfood), the better. This is what I learned and it is what I truly want to share with all of you. I’m not saying that my vision is the only legitimate one out there, but it is the way of eating and living that makes me happy.

I ensure that the lion’s share of my diet is plant-based. I choose vegetables and/or fruit as the key ingredient in my meals and add as few animal products as possible. Eating this way makes me feel better and I believe it is better for the environment. This is also why I tend to choose local, seasonal products. I do, however, like to experiment every now and then with ingredients from other countries and cultures… I’m definitely still curious and love to learn – especially when it comes to food. But no matter what, I make sure the food I eat is organic where possible. I like to support organic agriculture and think that chemical pesticides and herbicides are simply not good for the environment or our own health.

I believe that taking good care of yourself is also an essential part of a happy and healthy lifestyle. You are at your most beautiful when you care for your body. Taking care of yourself, of course, includes staying fit and healthy, but it all begins with accepting and appreciating the way you look. You are so beautiful. Really. OMG, take a good look at yourself! Even the things you think aren’t good enough are fantastic. Trust me. Maintaining a positive self-image is the most important aspect of self-care.

5. Exercise
I work up a sweat about three times a week. Working out has a positive influence on my health, my self-confidence and my focus. But even ‘exercise’ in a less intense form has this effect… Walking, dancing, jumping on a trampoline – I love it all! Getting enough exercise is essential to feeling good, but it is just as important not to be too hard on yourself.

6. Home
To me, my home is my protective cocoon where I can be myself. It’s my safe haven and literally my comfort zone. I can relax at home. Feeling at home depends on a number of factors for me, including light, cleanliness and calm. Having said that, everyone’s definition of a nice home is different. I create that safe-haven feeling with homemade scents and cleaning products, plants and good music. For you, something else might be key. Whatever you do, make sure that wherever or whatever you call home is a pleasant, healthy environment for you. You deserve it. : )

7. Planet
Sometimes I experience one of those moments, when I head out the door, on my own, into nature, preferably with bare feet, that brings me even closer to nature. It makes me feel good. We, as human beings, just like plants, animals, matter, meteorological and geological processes, space, atoms and energy, are a part of nature. We are all one. And we all call Mother Earth home, the planet that we are allowed to make use of. I think that’s amazing! And no, I probably don’t have to tell you how important it is that we take care of our planet. But I’m going to anyway… ; )

Terms like climate change, the collapse of biodiversity and plastic soup are ones that we hear more and more often these days. Unfortunately, things are not going well in terms of the health of our beautiful planet. We number in the billions and are exhausting the world. Because we live in societies characterized by mass consumption, we use huge amounts of fossil fuels, deforest massive areas and overfish our oceans. We emit far too much greenhouse gas. We also need to be concerned about the disappearance of insects – without them, we will be unable to grow food.

I am an optimist and believe that many things in life will turn out fine. But when it comes to the environment, I find it difficult to stay positive sometimes. There is, however, a positive way to deal with these feelings and to make a difference. I’m not asking you to go out a be a superhuman and save the world on your own. And spending your time feeling guilty about having being ‘less aware’ in the past is counterproductive. No, making a positive switch is all about the now. You can make a difference right now, just like I can. Saving the planet really does start with you. There are so many choices you can make that will contribute to making sure our planet stays habitable. Below is a list of a few things that I do to make a contribution. Maybe some of these will work for you, too…

– Connect with nature as deeply and as often as possible.
– Make sure the dishwasher is full before running it.
– I switched to an energy provider that delivers green energy.
– Shower only as long as necessary.
– If you’re cold in your house, put on a sweater before turning up the heat.
– Cook with natural materials as much as possible.
– Eat a plant-based diet.
– Reduce food waste.
– Recycle.
– I compost.
– And I have my own vegetable garden (window-sill gardens count, too!).

And now one more thing, full disclosure: I do have one big weakness when it comes to the environment. Flying. I really love to travel. But no matter how good it is for my mental health, I’m not doing the planet any favors by getting on a plane. I know this. I think long and hard before I book a long flight. A holiday closer to home can also be great. When planning travel, I also consider driving or taking the train instead of flying. Whenever I think about getting in the car to go somewhere, I consider whether or not I can bike or take public transport. Is it bike-able? If so, I get on my bike.

So, no, I’m definitely not perfect, but it all begins with awareness. I’m convinced of this. Every small step we take in the right direction has a positive effect on the future of our planet. It’s a reassuring thought. Something to hold on to as the future of our planet approaches.

Go get ‘em! 

That’s it. That is what my company and I stand for. These are the things that keep me happy and healthy and help me to strive toward the best version of myself. My vision changes every day based on the things I learn and experience, but what I’ve shared above is the basis of everything. It is and will always be the foundation upon which I build everything else.

I hope that this website inspires you to be the best version of yourself you can be without being too hard on yourself. I hope that it helps you find balance and motivates you to be good to yourself and your surroundings. I hope you can use it as a guide and that it offers a bit of support. Only you can lead your own life. No one else. 

                           With love,

Omringd door kokospalmen en zee, lopen blootsvoets, drinken vers kokoswater, eten het lokale eten, geen wifi. Heerlijk even! ☀️ ...

Gelukkig en vooral een gezond 2022! Ik heb de Gucot appelazijn natuurlijk in mijn koffer meegenomen naar Afrika en ga vanaf vandaag de hele maand weer lekker 1 el met ca. 300 ml voor ontbijt drinken met als goal om ontstekingen tegen te gaan en wat vocht te verliezen. En volgens mij ben ik niet de enige die meedoet aan de bestellingen te zien :)

Wat is jouw health doel die je wil bereiken deze maand met de challenge? 👇🏽


Lieve 2021, ik ga over jou schrijven en dit wordt een lekkere rauwe tekst zonder dat ik al te veel verbeter want daar heb ik helemaal geen tijd voor (;J) en daarnaast kan ik jou ook zo omschrijven; puur en raw! Want de ‘wannabe’ past niet meer. Ik ben wie ik ben. Bij mij zijn er dit jaar steeds meer laagjes afgepeld. Dankzij moederschap maar ook door deze tijd. Het voelt net alsof je mij, maar ook mensen om mij heen geholpen hebt om de deur nog wijder open te zetten. Een weg naar pure liefde. En dat je vele inzichten hebt kunnen geven zodat we tot de kern kunnen komen. Want aan alles voel ik dat dit is waar het leven om gaat. Je helemaal laten zien wie je bent. Om dat te kunnen doen moet je je trauma’s recht in de ogen durven kijken en het verwerken. En eerlijk naar jezelf kunnen zijn. En daardoor kan je mensen om je heen verliezen maar ook nieuwe voor in de plaats krijgen. En dat is wat er bij mij is gebeurd en nog steeds is. Ik ben er nog niet, want ik voel nog angst maar ik ben ver. En ik zal er aankomend jaar nog verder aan werken. Dank je wel voor deze intense tijd. Dank je wel voor de liefde, de boosheid die ik heb kunnen transformeren naar vergeving, de informatie die ik heb mogen ontvangen om verder te kunnen groeien… Wat een jaar. Je hebt mij verbaasd en onwijs veel gegeven. Up to the next. Liefs Rens

Waar ben jij dit jaar het meest dankbaar voor?👇🏽

We halen de bananen zo van de boom :) Wat een rijkdom 🇨🇮 ...

We go way back. En nu stond Moonsister @jettekevanlexmond opeens weer gezellig in mijn keuken om een lekker en gezond soepje te maken. Zo gelachen ook ;) Het filmpje kan je op de @moonsisters feed vinden. 🎄🥂 -x- ...

Je buikie is nu vast al vol en misschien zit je helemaal niet te wachten op deze post maar ik wil toch even deze feestelijke voedzame taart met jullie delen zodat je ‘em alvast op kan slaan voor de feestdagen. Nommm! De link van het recept vind je in mijn bio en de stories. -x- Sweet dreams. Rens ...

Ik heb nu al een jaar slaaptekort. En kan je eerlijk vertellen dat ik ontzettend moe ben. Voordat je nu een mening met mij deelt of gaat adviseren dat het beter is dat Maya in haar eigen bedje slaapt en dat ik borstvoeding moet afbouwen, wil ik eerst benadrukken dat ik aan alles voel dat dit het beste werkt voor mijn dochter. Maar dat betekent niet dat ik af en toe in huilen uitbarst of met kleine ogen naar mijn kantoor toe fiets. En ik weet dat dit tijdelijk is en die wallen voor een groot deel weer verdwijnen. Het is een fase! Het is nu even zwaar, maar weet dat het makkelijker gaat worden met de tijd. Dus in de time being beloon ik mijzelf met fijne dingen zodat ik weer wat oplaad, zoals met lekker eten en massages. Maar ook op mooie goede duurzame sieraden zoals @golldjewelry. Want we mama’s deserve that ;) We are GOLLD!

Ik draag hier de American Force necklace (met initalen van Sid en Maya) en mijn favoriete Papua Plate ring, check link in stories.

KRUIDIGE RIJST met PADDENSTOELEN | De laatste dagen van de herfst zijn aangetreden. Niet mijn favoriete seizoen maar wat ik wel fijn vind is dat ik nu meer zin heb om het binnen gezellig te maken en veel te koken. Dat komt trouwens goed uit want voor mijn nieuwe kookboek So Simple wil ik begin mei 88 recepten hebben gemaakt, getest en uit hebben geschreven ; )  

Dit recept komt er niet in maar toen ik ’em maakte vond ik wel dat ie het verdiende om gedeeld te worden. Het recept is heerlijk en het zorgt ook voor een lekker extraatje. Paddenstoelen zitten namelijk vol fijne voedingsstoffen. Een leuk weetje is dat tijdens het bakken er alleen nog maar meer vrijkomen. En heb er mijn eigen bouillonpoeder in gedaan (die is back stock, link in bio en stories). Je kan natuurlijk ook een andere blend gebruiken. Maar het voordeel van de mijne is dat het geen gist bevat dus beter voor de gut.
Ik hoop dat je het net zo lekker vindt als ik. Enjoy! #renskroes

Met mijn handen in het haar, haha. Ja.
Als ik een kookboek maak dan wil ik het hele proces beleven en dus zoveel mogelijk met liefde zelf doen want ik ben van mening dat je dat voelt zodra je mijn boek in de handen hebt. Maar goed, nu komt wel mijn punt,
Ik heb op dit moment zoveel kookinspiratie maar recept uitschrijven vind ik het minst leuke werkje. Ik ben dan mevrouw stelt het uit met dat soort dingen, haha. Wat vind jij het minst leuk aan jouw “werk” en/of hobby?👇🏽

Dit simpele en lekkere pasta recept krijg jij binnenkort als je mijn kookboek nu pre-ordered want dan ben je aangemeld voor de “‘So Simple’ nieuwsbrief. You gonna love it! De link staat in de bio (en renskroes.com) 💫 Had ‘em op stories geplaatst en kreeg zoveel enthousiaste reacties dus you ask I deliver ;) - x- Rens ...

Ik streef meer naar SIMPEL. Simpeler eten, minder bezit, kwaliteit over kwantiteit, rust, naar binnen, structuur. Jij ook? En hoe ziet een simpel leven er volgens jou uit? 👇🏽💫 ...

Dank je wel voor jullie mooie berichten afgelopen week. Wat een hectische en emotionele tijd voor mij. Ik zette mijn boek So Simple op pre-order maar door de 350k bezoekers op renskroes.com crashte die, BAM (lesson learned!). Nu zijn we alles aan de achterkant aan het fixen en lanceren we 10 november. Ik zal het hier delen als het zover is, maar je kan op die dag, als je bent aangemeld voor mijn nieuwsbrief, ook een mailtje van mij verwachten.

Besides all that werd ook mijn kleine meisje zaterdag 1 jaar wat de laatste tijd ook veel met mij deed. Zo onwennig! Ik had behoefte om de geboorte van haar met jullie te delen. Voor vooral de mamas (to be). Ik voelde dat aan alles. Niet vanuit mijn perspectief, want ik zat natuurlijk helemaal in mijn eigen wereld. Ik wilde de ervaring laten opschrijven door iemand die het van heel dichtbij heeft meegemaakt. Iemand die het met een hele andere kijk, een iets grotere afstand heeft mogen ervaren. Dank je wel @kassandra_schreuder voor je prachtige woorden. Ik hoop dat we velen hierdoor mogen inspireren. Het verhaal staat in mijn feed als je ‘em nog niet gelezen hebt.

We zijn nu met ons gezinnetje op reis en werk ik even niet op kantoor wat mij altijd zoveel inspiratie geeft. Even lekker uit mijn comfort zone ;) Misschien ooit een huis op wielen, met dan wel een moestuin? Hehe.

Lieverds, dank je wel voor de liefde die ik heb mogen ontvangen. Wat bestaan er toch mooie mensen op deze bol (of is ie plat? Hahaha). Dikke tút for yoouuu! Rens

Ik draag hier @golldjewelry natuurlijk. Check link in mijn bio. Love love love.
