I do it and find it very helpful to get out of my food rut, and I'm sure I'm getting a wider range of nutrients (and hopefully improving my gut health).
A lot of commentators here don't understand that herbs, spices, and garlic only count for 1/4 of a point.
I try to make sure I get at least two per week from each category. I did not often eat seeds, nuts or pulses, but now I do.
It's varied the type of fruit I eat. I live on my own and used to buy a couple of packs of fruit, say bananas and grapes. Now I'll buy 1 individual portion of, say, banana, orange, kiwi fruit, watermelon slices, red apple, green apple, tinned pineapple.
It's varied the veg too, like many people I'd eat plenty of the basics through the week but now have smaller amounts of a larger number.
It's not hard but means I put a bit more thought into what I eat.
For those saying, well I eat 10+ a day anyway, you are over-counting your herbs and spices - they aren't '1', and forgetting that you can't count the same things again that week. I probably eat 4 or 5 onions a week but only get to count them the first time. As you go through the week the daily totals tend to go down for this reason.
