The recommended daily fiber intake is 25g for women and 38g for men in the USA, and 95% of us don't meet this amount. This suggests an urgent need for us to increase our daily fiber intake, which can be achieved by swapping out ultra-processed foods and animal foods that are void of fiber with whole plant foods such as fruits, vegetables, legumes, whole grains, nuts, and seeds.
This is purely anecdotal, but I started meal prepping with a pile of mixed vegetables and chicken, and my bowel movements have never been smoother. Like, the difference was legitimately addicting. Haha. An effortless shit everyday is such a massive game changer.
I'll often toss a frozen package in the microwave to go with whatever I'm eating for dinner, then any leftovers go in the fridge to be remicrowaved the next night (they rarely make it more than 2 nights though, otherwise I'd be more careful about over-reheating)
