It's better to just use a water with e-mote to heal. Saves you money, time and food.
Get the water soul dodge and set your mote like this.

If you don't have mote then try and do your best with food. Go to chicken farm collect rice and cook it. You can also use the seeds you get to make syrup.

You can also go to beetle den find fruits and compound it to make juice

And finally you can get a rod, find a spot near a lake, ocean, almost any body of water or starters beach and fish or kill mobs near the watery areaa to get fish and cook that instead.

So try training in areas where you get food like Osyla which gives you meat, chickens give you rice, south pole gives you fish, relic island gives you fish etc..... places like that and cook the items you get.
