Green House delivers optimal fuel for the brain


Green House has been launched to create and deliver delicious,  nutrition-rich food;  salads, soups, sides, drinks and desserts to your home or office, providing optimal fuel for the brain.

Green House is the brainchild of Frederic Janssen.  Years of overworking in the hospitality industry resulted in depression and anxiety, and Frederic took a personal journey to find a solution.

After considerable research into understanding what he needed to do to feel better, he discovered that the answer lay mostly in the foods he should be eating. “After a while, having explored one by one the areas I needed to work on in my life, I understood that all of them were important to analyse and invest in, but that none of these efforts could work if the basic fuel to get me there was not right... food!” says Frederic.

Based on the emerging nutritional psychiatry ethos, a healthy Mediterranean approach to balanced eating, and findings from some of the world’s leading clinical nutritionists and medical professionals,  Frederic has used his accumulated knowledge and love of good food to create delicious dishes available from Green House, to enjoy at home or at your desk.  And it’s as simple as ordering from the online menu at 

Currently available in the City of London, Farringdon and all areas within a 1 ½ mile radius of Frederic’s Bethnal Green kitchen (plans to widen distribution are underway), Green House is at the forefront of providing delicious dishes which feed the nutritional needs of the brain, mind and body. The salads are delivered by Deliveroo, Uber Eats, Feedr and soon City Pantry in clever, sustainably-sourced origami boxes – their unique flower petal design opens up to reveal the delicious, artfully presented fresh ingredients inside.

“Food delivery is on the rise but there seems to be a lack of striving for true hospitality in the delivery world. At Green House, we want to ‘touch’ people with our delivery experience through our packaging, the same way a real restaurant engages with their guests to give them memorable experiences. And we wanted to do that at an absolute minimum cost to the planet,” says Frederic.

Green House uses whole, nutrient-rich ingredients and make all their dishes, desserts and drinks from scratch. Organic when possible, they use no preservatives or ‘E’ numbers. They sweeten with coconut sugar for their desserts, but never more than needed. Organic Extra Virgin Olive Oil is used for all their preparation as - according to their food ethos - it constitutes the keystone to a healthy brain diet. They make cunning use of exotic spices like ashwagandha, turmeric and Reishi to help influence mood through their food.

“When I was searching for convenient lunches in London that would help me in my quest to feel better, I couldn’t find anything that focussed on feeding the brain, so we have set out to deliver a new way to make it easier to eat well, to optimise the brain, even help our diners pick their mood, so they can be the best versions of themselves.

“What I am most passionate about is how food has helped me be a better person.  I went from being stuck in bed to creating Green House,” says Frederic.
