A lot of people hugely depend on supermarkets to source their food. They eat a lot of highly processed food. And even the “healthy” options on the shelves aren’t giving them the life energy they’d need to function in an optimal way: vegetables and fruit in supermarkets have often traveled a long way, are treated to extend their shelf-life, are harvested when not fully ripened, come from monocultures growing on depleted soil, etc. = they do not contain the nutritional value of a plant growing in a healthy, naturally balanced environment.
Another often underestimated and well-hidden factor in supermarket and processed food is sugar: producers use sugar in almost every processed product, even in the “healthy” and organic ones - check out in how many organic products on the market you'll find "organic cane sugar", agave syrup or other commonly used "healthy" sugar options. They all add up in your body and affect your body-mind-soul energy balance. We are literally clogging all our systems with the food we eat.
I know from my own experience as a “sugar addict” and “nutri freak” who has experimented with lots of different diets how much our eating affects our ability to connect. “Sweet cravings” are hardwired in our brain: to look for sweets was beneficial for survival when we still lived in caves. However, like with a lot of other things, we way overdo it in current mainstream society. Nowadays, sugar & sweet treats are widely available (and sugar consumption is actively promoted). We imprint our children and ourselves on sugar, install sugary habits and use it in quantities that are simply life-destructing. We numb our Selves and compensate the destructive effects of sugar-eating by… eating more sugar. Sugar = quick high.
"Tired, overworked, depressed, challenged? Have a sweet treat and you’ll feel better instantly."
Nature helps me to do this and has a recalibrating effect. I found that it helps me immensely to resist the omnipresent sweet temptation when I am a) slowing down, and b) immerse my Self in nature. I have observed this effect not only on my Self, but on many people.
By the way: Damon Gameau just released a good movie about the effect of sugar on the body – watch it, even if you know already a lot about this topic (That Sugar Film).
