Does the redirection of the start page help on a page with keyword targeting in SEO?

My website is pretty new, for example I need to tweak the homepage ( for a keyword. to eat healthy food.

If the homepage is redirected to, this would be useful in terms of search engine optimization because the URL contains a keyword that the page is targeted for.

The problem with adding an additional redirect is that adding 300 ms of additional latency when accessing the homepage will help me avoid it.

I do not want to put the same content on and because duplicate content will be flagged.

Please advise.
