I had some random fruits at the bottom of the bin, so I decided to add a clementine to the grapefruit juice I’d been having in the mornings lately:

As you can see, it’s a little more orange… It was also a lot sweeter, so this would be a great juice to try if you want to add more grapefruit to your routine but find it too tart. I can’t imagine an all-clementine juice fitting under my “oh crap that’s too sweet” threshold, but though I’m sure I’ll end up trying it sometime for a Monday One-Day
I’ve no idea what the nutritional benefits of clementines are that might be separate from what you’re already getting from the grapefruit. Mostly this is a “hey, these are easy to peel!” solution when you’re fighting to finish off a crate of those little oranges.
Today’s single-ingredient juice is grapefruit. I honestly don’t remember if this was a red, pink, white, or teal* grapefruit, but this is one of my favourite pick-me-up juices for the morning:

As with all juices, your throughput will vary according to the size of the fruits used and to a lesser extent your juicer, but I’m finding that 2 grapefruits fill up a pint glass pretty nicely. I use the Jack LaLanne juicer for this one.
Grapefruits are crazy good for you and have a relatively low sugar content. I thought the facts presented here were pretty interesting, including the study where people who ate grapefruit with every meal lost weight – I’m not going to look into it too much (too many other great fruits and vegetables to try!) but just knowing I can nail my vitamin C and A RDAs with one glass of juice is pretty cool.
This is also one of the examples of what I love about juicing: I find my teeth get sensitive if I eat too many citrus fruits in a week (like, more than one every other day or so,) so juicing is a great way to enjoy the flavours with less irritation.
* one of these varieties is made up. Guess which one!
