That bottle of tomato sauce in your fridge could be anywhere from 53% tomatoes to 87%. And the brand that comes out on top will probably surprise you.

This week on The Nutrition Couch, Leanne Ward and Susie Burrell work through the supermarket sauce aisle so you don't have to, then unpack the creatine sleep study that has been all over your feed.

The tomato sauce ranking every family needs
Leanne reveals which sauces have the highest percentage of tomatoes, which ones quietly swap sugar for sweeteners, and which "fancy" glass bottle brands are among the lowest in the aisle. She also shares the three brands to choose if buying Australian-grown tomatoes matters to you, because the top performers mostly aren't. Susie's top picks will be on our Instagram as a swipe-through so you can save them for your next shop.

Does creatine really give you 48 more minutes of sleep?
The headline is real, but the study behind it is far more specific than Instagram is letting on. Susie explains who was actually studied, why the benefit only showed up on certain days, and what it means for women in perimenopause and menopause. Leanne then covers a completely different line of research on creatine and sleep deprivation, which is very relevant for shift workers and parents of little ones, plus the one safety point you can't skip if you take more than the usual dose.

Plus:
Leanne gives her verdict on Susie's new favourite supermarket crumbed chicken, and a listener asks the hosts to settle a sister showdown: is carob actually healthier than chocolate? The answer comes down to one number on the label most people never check.
