How about acorns?
Stupid article didn’t say which type of nuts. Almonds are good for B 6, apples for their pectin and roughage. Oatmeal is good source of fiber. Not all nuts provide the same health benefits. And it didn’t say how many you had to eat per day. Nuts are high calorie.
You can lead a squirrel to an acorn but you can't make it do a web search.
This is but a medical news article. The rest is up to you.
