It's probably still better to avoid eating french fries regardless of what they're fried in. That would probably lead to better health outcomes regardless.

Unless you're claiming that it tastes better, then sure, beef tallow is pretty tasty.

If you are eating french fries once or twice a year they probably are not bad for you (by enough to matter, and perhaps even good if they give some micro nutriant you are not getting elsewhere). And then by all means eat them friend in beef tallow because that tastes better.

If you are eating french fries twice a week - which seems to be common - they are bad for you. Clean up your diet, eat a larger variety of food.
