chia pudding is my 'eat 2 spoons and done' no-brainer, zombie-mode breakfast and has been for months.
(It's just 4Tbsp of chia seeds with 1 cup almond milk, a splash (maybe 1/2 tsp)? of vanilla essence, and about 10 frozen blueberries thrown in a mason jar and shaken then left to sit in the fridge for about 4 hours (the blueberries defrost in the fridge while the chia pudding is congealing) - i've tried a few different recipes but this is by far the easiest and the least heavy feeling (using greek yoghurt or soy milk or anything cocoa based just never tasted or sat right). They're a nutrition powerhouse and i wish i'd gotten on the bandwagon sooner. I've seen people dress them up and down and that's where the extra sugar and calories can come in to it, but they're a good soluble fibre vehicle for plant based omega3 fats and protein.
Berries are low in fructose and given how much Western diets usually lack fibre, they're always a good inclusion on any eating plan because of their anti-oxidants etc and fresh/snap frozen are nutritionally equivalent. Fructose by itself is usually more of a problem in large quantities like when you drink 5 oranges at once in juice (with or without added sugar ) whereas if you eat an orange, most people would stop at one and the fibre slows down digestion and the insulin response to the sugars anyway although some people have trouble actually digesting fructose and breaking that into it's smaller component sugars and then drinking juice really highlights this problem but then they think they can never eat an actual orang again - anyway, went off on a bit of a tangent.. sorry if i sound like a spammer!
In terms of changing up coffee or just anything where you physically add sugar, spices like cinnamon and nutmeg can help (i use cinnamon); can't say i love turmeric lattes but i can't do green tea, not for lack of trying but switching in herbals like chamomile or orange and ginger teas for me means i drink less coffee anyway - i cringe when i hear people talk about putting butter in coffee, but there are lots of food things that make me think 'what the' or just 'why?'. Carbonated water (some have just lemon juice added but others have sweeteners) going in to summer is a good substitute for soft drinks/juice but i'm not a fan of any of the artificial sweeteners and will often just buy the plain one and add lemon to it myself (because i'm a control freak and may have trust issues like that). Best of luck with your admirable goal!
