Low-cholesterol diet tips and recipes?

I’m looking for anyone who actually knows about this cholesterol-lowering diet to
share their thoughts or experiences...
My doctor prescribed it, but my Google searches have been a total dead end 🤷

Anyone here? 😢

So my mom was just telling me today about how she managed to drop her cholesterol from a crazy 9.6 down to a 6 in just two months. It’s wild. She didn't touch any meds, hasn't even started hitting the gym, and she’s 70 with a lifetime of cholesterol issues.
Basically, she just cut out all the junk and sugary stuff that spikes levels and replaced it with more chicken, fresh fruit, veggies, fish, and other healthy staples. Plus, she used this one supplement that she's convinced did most of the heavy lifting. Here’s the recipe:
10 oz sunflower seeds
10 oz pumpkin seeds
10 oz sesame seeds
10 oz flaxseeds
5 oz cinnamon

Just mix everything together, grind it up real fine in a coffee grinder, and she takes 2 teaspoons of it every single morning.
