I agree with Ejeff. I don't mean to sound harsh, but your husband isn't really following a WFPB diet. Please look at
this from SnackWell's website.
The 2nd, 3rd, and 4th ingredients are sugar. The 5th is hydrogenated oil. The 7th and 9th are oil (lecithin), and the 8th is gelatin (derived from boiled hooves). Nixing these cookies from his daily diet (often 2 times/day) should help with his overall health and his hypertension. Normally I'd think replacing the cookies with some fruit would be a nice option to help satisfy a sweet tooth, but your husband already is consuming quite a bit of fruit.
Is he getting enough starch (potatoes, corn, whole grains like rice, quinoa, etc., some lentils/beans)? Yes, unless the store bought hummus is Engine 2 from Whole Foods, some varieties of Oasis brand, or maybe others, all other store bought hummus contain oil and salt. It really is easy to make no-oil hummus at home.
Have you tried whole wheat pasta? Pasta that has vegetable protein added isn't needed nor recommended.
So, as I mentioned, this really isn't a WFPB diet and certainly not The McDougall Plan that your husband is following. As Ejeff pointed out, the pasta sauce more than likely contains oil, too. By making these little tweaks, they really can add up to helping your husband!
Also, I couldn't find whether or not it could contribute to elevated blood pressure, but the cereal he eats contains BHT. It is a chemical that
may adversely affect him.
Thank you for asking your question and giving us so many details; that was great! Please ask any other questions you may have including help with recipes, etc..
