She also collects rainwater to drink and water her plants.
Larkins says the food in her garden is her Fountain of Youth.
"I am very vibrant, I have lots of energy, as I told you before, I am up no later than 5:30 in the morning as a rule, and I am ready to go," she said.
Larkins' husband owned a meat store in the 1960s. That's when she became a vegetarian. As the years went by, she became a raw vegan. Annette says she does not eat animal products. Her food is unprocessed and uncooked.
"My diet consists of fruits, nuts, vegetables and seeds. I do a lot of sprouting of seeds and as you can see from my garden and of course these are the raw foods that I eat," she explained.
Larkin also juices fruits and veggies.
Still, not everyone in the Larkins' family eats and drinks this way.
Annette's husband Amos chose to continue to eat the way he did when they were first married.
"I really wish I would have done what she did," he says now.
Amos says people even wonder if Annette is his wife.
"They will ask me 'what am I doing with a young girl? or they will say 'you've got your granddaughter with you,' things like that," he said.
Amos Larkin takes prescription medicines daily for high blood pressure and diabetes.
Annette Larkin says she does not even take an aspirin.
After friends and strangers kept asking her questions about her health and youthful appearance, she decided to publish two "Journey to Health" booklets, and she produced a DVD 12 years ago.
So how old is this size-4 beauty?
Annette just turned 70-years-old.
Annette says friends her age see the difference in her quality of life.
"This one lady who is my age, she was telling her friend, that I used to tell them about eating and they would not listen and her response to that was look at her now, and look at us," she said.
Her husband says she is vibrant person.
"She is an amazing person, she does everything. I mean she builds computers, makes all of her own clothes, grows her own food, speak three languages, it's amazing," says Amos Larkin.
