Here are many references in the Bible where God instructed us how we should eat. The first of these references can be found in the first chapter of Genesis:

Genesis 1:29
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 meat.

We have taken the seed out of our diet nearly 100%. The seed is supposed to be a main course in our diet, just like it is among the cultures that are not afflicted by cancer. Some of these cultures are discussed in the video.

Ezekiel 4:9
Take wheat and barley, beans and lentils, millet and spelt; put them in a storage jar and use them to make bread for yourself.
This biblical recipe contains b-17 and was given as the key food for Ezekiel while he was to lay on his side for 390 days.

John 11:4
When Jesus heard that he said "This sickness is not unto death but for the glory of God, that the Son of God might be glorified thereby.

Psalm 103:1-5
Bless the Lord, O my soul: and all that is within me, bless his holy name. 2. Bless the Lord, O my soul, and forget not all his benefits: 3. Who forgiveth all thine iniquities; who healeth all thy diseases; 4. Who redeemeth thy life from destruction; who crowneth thee with loving kindness and tender mercies; 5. Who satisfieth thy mouth with good things; so that thy youth is renewed like the eagle's.

Here we are promised health and redemption from destruction. It goes on to tell us that our youth will be renewed like the eagle's as we satisfy our mouth with good things. Any commentary will support that this verse is directly speaking of food.
 

Corinthians 1:27
"But God hath chosen the foolish things of the world to confound the wise; and God hath chosen the weak things of the world to confound the things which are mighty;"

Exodus 15:26
And said, if thou wilt diligently hearken to the voice of the Lord thy God, and wilt do that which is right in his sight, and wilt give ear to his commandments, and keep all his statutes, I will put none of these diseases upon thee, which I have brought upon the Egyptians: for I am the Lord that healeth thee.

James 5: 14-16
13 Is any among you afflicted? Let him pray. Is any merry? let him sing psalms. 14. Is any sick among you? let him call for the elders of the church; and let them pray over him, anointing him with oil in the name of the Lord: 15. And the prayer of faith shall save the sick, and the Lord shall raise him up; and if he hath committed sins, they shall be forgiven him. 16 Confess your faults one to another, and pray one for another, that ye may be healed. the effectual fervent prayer of a righteous man availeth much.

Prov 10:16
16 The labour of the righteous tendeth to life: the fruit of the wicked to sin.

John 11:25
Jesus said unto her, I am the resurrection and the life: he that believeth on me though he were dead yet shall he live: 26 And whosoever liveth and believeth in me shall never die. Believeth thou this?

Hosea 4:6
"My people perish for lack of knowledge"
