That sounds a lot like what I was trying to do for too long. Probably lots of variations, basically HIGH STARCH. UUGGHHH!!! Pretty close to what SDA’s typically preach, I would know… 
McDougall was another one. We were all gonna eat like that and get healthy, live to 120 with no health issues, yada, yada, yada. Nope.
Processed food was the devil… except for their famous “rubber meat”. (That stuff was about as unhealthy as it gets. Yet on Saturday evening, campmeeting, after sundown, the rubber meat sale began, mediocre bargains on stuff they all wanted, most knew better, and a whole lot of ‘em just did it anyway. Bless and regress… LOL! And potluck? Carbs & sugar, rows and rows of it. And desserts, oh those were diabetes at 40 yards. "Good ol’ health message", my foot.
(Sorry, I am a little cynical about it all still. I poke fun. But there are some good and sincere (though sincerely wrong) people stuck there. I feel for them. But I also know that many would rather die than admit there is a problem. Sad.)
