Except one steer gives you about 400 pounds of beef (https://www.skipperwbreeders.com/recommendations/quick-answer-how-much-meat-can-you-get-from-a-cow.html https://www.skipperwbreeders.com/recommendations/quick-answe...). 400 pounds of Cashew nuts? Man that's a lot of trees. Not to mention the other nutrients in beef. A piece of beef contains everything a human needs to live. You could just eat beef and you'd probably not be great, but have all your nutritional requirements met. Cashew nuts... no. According to https://www.quora.com/How-much-fruits-and-nuts-does-one-Cashews-tree-produces-in-a-year?share=1 https://www.quora.com/How-much-fruits-and-nuts-does-one-Cash..., to produce 500 pounds of Cashews, you need 2.47 acres. Now compare this to a pig, which, if you slaughter it at around 270lbs, yields about 154 pounds of meat. That means 3-4 pigs will give you enough meat as 2.47 acres of cashews, and pigs eat everything. Pigs can be kept with about 8 sq ft per pig: https://familyfarmlivestock.com/how-much-space-do-i-need-to-raise-pigs/ https://familyfarmlivestock.com/how-much-space-do-i-need-to-... Beef is definitely less efficient as a form of meat. It's also not the only form of meat. If you had a few acres to grow things, you should grow some vegetables and a whole lot of forage for your pigs, which will constitute the base of your diet.
