Absofruitly!
Genesis 1:29 says "And God said, Behold, I have given you every herb bearing seed, which is upon the face of all the earth, and every tree, in the which is the fruit of a tree yielding seed; to you it shall be for [food]."In the context, God is telling Adam that plants, fruit, and seeds are good and healthy for us. Interesting! It's safe to assume that Adam and Eve ate only things mentioned in these categories until after the Fall.
But how about later on..?
In Genesis 27 talks about the custom of the eldest son bringing his fathers favorite meal to him before receiving the blessing of the firstborn.... well the original Jake pulled a slick one and beat his elder brother Esau to the punch.....but that's beside the point. In 27:17 it says Isaac's wife Rebekah "gave the savoury meat and the bread" to Jacob for him to take to Isaac. He did and Isaac chowed down. Isaac lived 175 years and his favorite food was Plate of Meat.
Finally, it's interesting what God prescribed for the first Passover meal in Exodus 12:
"eat the flesh [of the lamb] that night, roast with fire, and unleavened bread; and with bitter herbs they shall eat it." So here God's prescription for a good meal for an active person (they were about to high tail it across the wilderness with the army of the mighty Pharoah in hot pursuit) included lean grilled red meat, some wheat wraps, and a little salad.
So in conclusion, if the Bible is all we had concerning nutrition...then using just these 3 examples we find that fruit, seeds, vegetables, grilled meat, and small amount of wheat bread are pretty good choices!
