Our brains love sweet things; the sweet flavour promises a provision of quick, easy to access energy from sugar, that makes our nervous system fizz with sensation, & eating sweets literally makes us feel good by activating the mesolimbic dopamine system.
So, enjoying naturally sweet foods as part of your diet is as a totally normal thing to be doing. What we want to avoid however is unbound, nutrient poor sources of sugar/sweetness as these negatively impact our health & wellbeing.
You’ll also find that regular consumption of these unbalanced or more synthetic options distorts taste perception which leaves you craving sweet foods in excess of natural enjoyment, as well as destabilising energy & hunger levels generally. So it’s a yes to natural sweets & ‘treats’, finding joy & delight in seeing your body respond positively to them, & leaving the less optimal options out in the cold where they belong.
