Depends on the feeling and the emotion. For instance, various smells trigger both 'emotions' and 'feelings' due to the positioning of the amygdalae and hippocampus, and are particularly effective at triggering various neuron chains of activity. Your sense of smell is also relevant to feelings or emotions (which are nondescript when talking about them at such levels) concerning all sorts of things. Sexual arousal, long term memory store, etc...
Your 'feelings' about sugar, for instance, trigger various behavioural states and create emotional attachment to the food you're eating. For instance, you give someone one new, exciting food to eat each morning and the mental stimulation this causes wanes over time ... but foods with high sugar or salt content? Those maintain psychological stimulation much akin to a pleasure response feedback that take far longer to wane regardless of growing familiarity.
I could cook you simple low salt, low sugar scones each morning. You might not have had scones for breakfast. You'll fucking love it the first morning on their own due to the fat in the cream ... But eventually you'll get tired of them. But what is more habit causing is those pancakes dribbled with maple syrup. That is far more likely to become a habit. So is buying a bag of salt-riddled crisps at the research centre vendors like I do because I can't be arsed making breakfast.
Hence why numerous scientists are struggling with the idea as to whether we should classify artificial sweeteners in sugar substitutes for coffee and soda drinks as a harmful drug.
Largely unconsciously your taste buds respond to artificial sweeteners roughly 500 times more positively than white, processed sugar. This triggers your body and your mind to assume you have consumed ridiculous levels of carbohydrates and you adjust your behaviour to match. But given the calorie load isn't there this causes a feeding response that impels some people to consume more food or feel particularly hungry.
Increasing irritability, agitation, restlessness, dizziness, anxiety, sudden fatigue and so on.
Which is a purely biochemical cause of emotionality and 'feelings' from the subject of artificial sweeteners consumption.
People are putting up an artificial barrier between emotions and feelings that are non-descript or utterly unfound in the scientific explanations of human behaviour and neuroscience.
There is a difference between feelings and an emotion, but they inform eachother. I regularly go to watch the ballet. That informs me of witnessing (a sense) a particularly graceful dance, that provokes an emotional response otherwise not found in someone not so versed with dance.
A survival skill I was taught to use in the army durinh selection was to chew whatrver food you had slowly and as much as possible if supplies are short or the difficulty of resupply reduces access to foodstuffs. You can temporarily reduce hunger and the psychological effects of hunger, by tricking your brain into assuming you've eaten more food than you have.
As your brain monitors food consumption partly by how hard you chew and the rocking back of your jaw while eating. So small quantities, well chewed.
This has numerous behavioural benefits for soldiers who go for days without adequate sustenance, albeit highly temporary and with diminishing returns the longer such conditions continue. Including higher morale, reduced fear, and increased patience. There is also some minor support for the idea that chewing on things improve thingd like a sense of security and decrease fixation on personal suffering. It's a natural "mind-keep'r-off-erer".
