Booker if you want citation try this- very simplistic but a seminar I attended on the origins of public health law which cited far more citations including early regulations on drinking water and cleansing of blood of others from the body.
Some of the simple, yet very important, health laws found in the Bible are to:
Eat your meals at regular intervals (Ecclesiastes 10:17).
Don't overeat (Proverbs 23:2, Luke 21:34).
Make mealtime a happy time (Ecclesiastes 3:13).
Don't harbor envy or hold grudges (Proverbs 14:30, Matthew 5:23,24).
Maintain a cheerful, happy disposition (Proverbs 17:22; 23:7).
Balance work and exercise with sleep and rest (Exodus 20:9,10, Ecclesiastes 2:22,23; 5:12, Psalm 127:2).
Keep your body clean (Isaiah 52:11).
Be temperate in all things (1 Corinthians 9:25, Philippians 4:5).
Avoid all harmful stimulants [Note: Medical science has confirmed the fact that tea, coffee, and soft drinks that contain the addictive drug caffeine and other harmful ingredients are all positively damaging to the body]
Help those who are in need (Isaiah 58:6-8).
Bury body waste to avoid disease (Deuteronomy 23:12-13). [Note: This is obviously for health reasons, because history and science has shown that if this was not done, diseases would spread and people would die from them]
Avoid eating animals that were strangled (Acts 15:20,29; 21:25).
Avoid eating animals that die by themselves (Leviticus 17:15; 22:8, Deuteronomy 14:21, Ezekiel 4:14).
Do not boil a young animal in its mother's milk (Deuteronomy 14:21).
Do not eat animal fat or blood (Genesis 9:4, Leviticus 3:17; 7:23-27; 17:10-14, Deuteronomy 12:16). [Note: Recent scientific studies have confirmed the fact that most heart attacks result from a high cholesterol level in the blood -and that the use of "fats" is largely responsible for this high level. Also, the blood can transfer diseases. Science is just catching up with the Bible. ]
Put full trust in the Lord (Proverbs 4:20-22; 19:23).
