Also, experiment with cheap veggies. I get sick of PB&J, so I stick things like cucumber slices or mushrooms in there, and it seems totally different to my taste buds. Cucumbers are dirt cheap, mushrooms less so, but either way, not breaking the budget. I also enjoy a zucchini sandwich (between buttered toast).
Another way most people could cut their budgets is to look seriously at their portion size. I realize this doesn't apply to you, but if one's definition of a 'meal' is what fills up a 15 inch dinner plate and involves at least four different colors, then yeah, it's hard to eat cheaply. Most restaurant 'meals' are really at least two.
(Exception runs for certain restaurants of course. The more "mainstream chain" it is the bigger the portions get...)
Hell, I've even had to cut down on my portion size. Find good, nutritious food that is filling, and go for stuff that is slower to digest. I've now just about halved my carb in take and replaced it with vegetables, and I haven't felt better.
Excellent point.
And then it may be too late to do anything about it.
The first clinical symptom of cardiovascular disease is often sudden death.
Many cancers are "discovered" after they've been growing for 20 years.
Poor nutrition is often a primary cause of both.
