Why I use filtered water for cooking

Whenever I return home after traveling, the one thing I look forward to even more than sleeping in my own bed is cooking in my own kitchen! I’m always grateful for the opportunity to try new dishes (and who doesn’t love having someone cook for them) and I find so much inspiration in it that I just can’t wait to get to work creating.

As I mentioned in a previous post, I found a renewed appreciation for plant-based dishes when I was in Bali. I’ve made it a priority to incorporate more vegan meals, and that often does mean cooking at home.

I talk a lot about using quality ingredients: budgeting for organic where you can and incorporating local produce when possible. But another key to healthy cooking is the very base for most dishes. Believe it or not, the quality of your water is extremely important.

I am adamant about using filtered water, and here’s why:

  • It can help remove dangerous contaminants: physical contaminants like sediment, microbial contaminants like parasites, and chemical contaminants like nitrogen, pesticides and even toxins produced by prescription drugs.
  • Dangerous contaminants are removed, while retaining the healthy mineral deposits that balance the pH of drinking water – keeping the good stuff.
  • Water tastes and smells better when chlorine and bacterial contaminants are removed.
  • It can reduce the risk of gastrointestinal disease

Most fine restaurants use filtered water for cooking – why shouldn’t treat ourselves to the finest at home too? That’s why I use a filtered water not just for my drinking water, but for the water I cook with too.

I’m grateful to have a Zip HydroTap installed right in my kitchen – it’s super simple to fill everything from drinking glasses to stock pots. I love that pure tasting chilled, boiling and even sparkling filtered water is available in an instant! Need more convincing?

  • Although many bacterial organisms are destroyed in high temperatures, most food isn’t cooked at a high enough temperature long enough to take care of it all.
  • Chlorinated water can cause cooking water to taste odd, which could affect the taste of grains and pasta.
  • Grains and pasta will cook faster and have a creamier texture.
  • Chlorine can affect yeast, which is a problem if you’re baking certain breads like sourdough.
  • Cleaner fruits and vegetables. You can prevent contamination by washing your produce in filtered water. Give your salad greens a good rinsing, too – even if you buy packaged greens that claim to be prewashed, do it again!
  • Better tasting coffee and tea – you’ll likely find that they have stronger flavors and less steeping time when made with filtered water.

Even your kitchen herbs will be healthier when fed filtered water! Some studies show that plants can survive longer (weeks, even) in a vase of filtered water, and their growth can increase by up to 30%. If plants respond better to filtered water, there’s no doubt our bodies do too.

And with that, I’m happy to share a favourite plant-based dish that I’ve been loving lately.

Hi Jessica, I believe in synchronicity so when I was guided to you .on FB I was intrigued and inspired. I turned 46 last week and my husband bought me your book. I wanted to thank you for sharing your wisdom in such a beautifully presented way. My  copy is now filled with tabs and post it notes with actual notes throughout. I am dairy intolerant since having my gallbladder removed 15+ years ago, I don't eat meat, very minimal gluten and was told 12 months ago my gut was not digesting my food properly so I wasn't receiving sufficient nutrients and taking supplements would be a waste of time.  My weight fluctuates tending to gain rather than lose but now I believe I have a tool to help me bring my body back into balance that I need for my health and longevity of life - so again thank you. The first few steps to creating a stronger path forward for my health has found its foundation in your beautiful book, The Healthy Life.

With kindest regards Samantha

I'm writing this email because I wanted to tell you how much I love your blog and how you really helped me in my health journey. Thank you for sharing all your advices and experiences.

When I started my studies, I was drinking lots of coffee and I was eaten the wrong foods, and feel bad about it, I wasn't at my best. So I had done some research on the net but at first I didn't found advices that are for me, and then I found your blog. It was exactly what I was looking for, good advices and healthy recipes. Now I'm following your advices on rest more, and snacks between meals and prep the meals and take time for myself to reconnect with my body and let go my anxiety, etc, and I have a more balanced life and have a new relationship with food thanks to you.

I bought your book and it's honestly the best book I have ever bought. I suffer from IBS and anxiety. I have paid so much money seeing naturopaths however after reading your book and all of your tips I'm noticing so much of a difference, so simple and easy to follow. And symptoms have dramatically decreased. Also you have helped me to relax. Currently drinking the protein health smoothie! Thankyou your amazing.


Hey Jessica!
I haven’t yet brought ‘The Healthy Life’, but I do have the clean life and your slim down plan! I would like to thank you so much for the knowledge your share and the message you put across about health and wellness. I’m studying Nutritional Medicine in Melbourne and absolutely love the philosophy that you share with your JSHealth community. The work you’ve done to show people that leading a healthy lifestyle isn’t boring, tasteless, difficult or depriving is amazing and hope to share the message myself one day. You’ve inspired me to start my own blog , to share the message and have taught me so many things about my own health! You should be proud of your achievements! Thank you again

I searched for help and tips through the Internet and found Jessica Sepel. This is seriously not exaggerated, but she was the reason why I have dared myself to eat again, to have snacks in between, to nourish my body. I could slowly improve my negative thoughts about my body image and my stupid anxiety of gaining weight. Besides, The Cleanest Gut was awesome too! A huge thank you! Especially from my mum. Seriously, without you I wouldn’t be where I am now!


Congratulations on your new book! It looks absolutely gorgeous. I’ve been following you on Instagram for a few years and you’ve inspired me to slowly but surely eat healthier without giving myself a hard time when I don’t. It made me so happy (and weirdly proud) to see the Daily Mail article on The Healthy Life. I remember trying out your recipes before you even had your eBook out! I can’t wait to get my hands on the book. Keep up the great work.

Cooking in this way truly brought out the foodie in me and has instilled a huge passion for health and wellness! Life throws you hard and frustrating things sometimes but I truly believe that this is where we learn more about ourselves and what our passions in life are! Thank you for inspiring me on my journey to health and wellness!


I am a yoga teacher in Johannesburg and am thrilled to have bought your book today. I love making healthy, nutritious food for my family, friends and fellow yogis! Thank you for this book and your inspiration (had to share a pic of my book on my recipe stand in the kitchen).

– Helene

I bought your beautiful book during the week and told my bestie to go out and buy it also! I love love love it. It is the book I would give to my younger self if I could (I am 41 years old). Everything is just so sensible and informative and is definitely a book all teenagers should have. This should be a text book for girls becoming teens. I will love going back and re-reading it many many times and can't wait to make more of the recipes. Thank you Jess - you are an incredibly inspiring woman and you should feel so proud
