The health dangers of trans-fatty acids have been known for a long while. They don’t occur in nature (which is probably why they’re so bad for us).
As far as I’m aware nobody claims trans fats aren’t bad.
False as worded. Not sure if this is because you’re oversimplifying a complex topic or were just unaware of some edge cases. E.g., vaccenic acid occurs in nature and is thought to be good for us, last I checked. There may be a few other natural species that are similarly harmless.
On the other hand, there are unnatural trans fats found in things like partially hydrogenated vegetable oils that are evidently bad enough for a government ban. If identical molecules are still getting in our food in significant amounts from other sources, that could be a problem.
One can also use Vim to edit clipboard text. I’ve experimented with a few ways. Here’s a published example of how it could be done (from someone else). Adding a keyboard shortcut makes it faster when you’re not already in a terminal. You can edit (e.g.) web text boxes with Vim this way, although active JavaScript doesn’t always react to a paste the same way as typing. Depends on the page.
