In this task, you're given a review from Amazon's food products. Your task is to generate a rating for the product on a scale of 1-5 based on the review. The rating means 1: extremely poor, 2: poor, 3: neutral or mixed, 4: good, 5: extremely good.
One example: I have bought several of the Vitality canned dog food products and have found them all to be of good quality. The product looks more like a stew than a processed meat and it smells better. My Labrador is finicky and she appreciates this product better than most.
Solution is here: 5
Explanation: The user really seem very satisfied with the product and gave good review worthy of 5 stars rating.

Now, solve this: I've recently been researching the work of Dr. Price and the X-factor that high vitamin butter, combined with fermented cod liver oil, will cause teeth to re-mineralize and stop tooth decay. If this is why you want to purchase this product, DO NOT. I'm sure it's fine for ghee, but when I switched from the pricey butter oil to this, I found cavities were growing. When I switched back, they stopped growing. Again, this is great for ghee, but don't use as part of preventing/curing tooth decay as Dr. Price's research recommends.
