THE GLOBAL HEALTH PROBLEM• Currently there are 7 Billion people on Earth. By the end of this Century, Earth will have 3
billion more babies.
• Earth’s physical environment (water, air, Global Warming) is being Irreversibly altered.
• Earth’s Bio-ecosystem, as it relates to human food supply, is stressed (Crop failures,new microbial invasions,etc.).
• Human biological adaptive genome, acquired slowly over millions of years by biological evolution, is becoming stressed by the laser-speed changes in our cultural evolution, by the food/diets that are changing. This includes changes in the human gut microbiome.
• Currently, the limited health care resources, devoted towards the Global Health Crisis, is via “crisis medicine” [dealing with the Metabolic Diseases, e.g., diabetes, cardiovascular diseases, cancer, dementia, which are, in large part, caused by bad diets/nutrition] are insufficient to meet the needs of these adult chronic diseases.
One Planet-One Health
1. “Feast or Famine” style of eating
2. Eat within walking distance.
3. Eat only during the day
4. Seasonally-available foods
5. Grains, nuts, fruits, water- associated animals ( omega-3- fatty acid-rich foods).
6. Ate these foods without grilling.
7. Low caloric intake
1. Caloric Unrestricted.
2. Foods are processed
3. Foods are found year-round
4. Eat 24 hours a day.
5. Red meat/ grilled or fried
6. Use of dietary supplements
EARLY HUMAN DIET MODERN WESTERN DIET
Potential Partial Solution to these Problems
Since many of these acute and chronic human disease are influenced
during normal human development during in uterine exposures,
prevention of harmful factors during the pregnancy of these 3 Billion new
babies would seem to be both moral and scientifically achievable goals.
Education of new parents of healthy diets during pregnancy and neonatal
development should be a moral and political global challenge,
recognizing enormous cultural , economic , political and
scientific/technological barriers. A shift in how the distribution of limited
health care resources are to be spent on “crisis” versus “preventive”
Medicine will take courage.
This goal is based on the scientific basis of the Barker Hypothesis.

Prenatal exposures can influence the
risks to diseases later in life
PREVENTIVE MEDICINE STARTS HERE
PREVENTIVE MEDICINE STARTS HERE
BARKER HYPOTHESIS Few Examples• Maternal obesity increases risks to offspring
obesity, metabolic syndrome, hypertension, kidney size, lung function, polycystic ovaries and cancers.
• Diethylstilbestrol (DES)- induction of human vaginal cancers
• Bis-Phenol A induction coat color & obesity in rats
• Soy product reduction of breasts, breast cancer and induction of osteoporesis. Facts of the study of the atomic bomb survivors.
