The History of Nutrition: A Global and National Perspective

Ancient Egypt (3000 BCE)

practiced dietary regulations related to health, particularly among their priests and royalty. They believed that the consumption of certain foods could either enhance or diminish ones vitality.

mention foods that promoted healing and vitality, including garlic for its antiseptic properties. However, their understanding was based on superstition and trial and error rather than scientific evidence.

hippocrates

Father of Medicine, made significant strides in conceptualizing health and disease.

Ancient Greece (500 BCE)

Hippocrates suggested that the right foods could restore balance to the body’s "humors,a concept that preceded the modern understanding of biochemistry but laid a foundation for future theories in nutrition

Hippocrates introduced the concept of the four humors:

Ayurveda (India, 1500 BCE)

texts like the Charaka Samhita detailed dietary practices to maintain health, emphasizing the importance of food that suited one constitution (doshas).

vata,pitta,kapha

teaches that every person has a unique body constitution (Prakriti) based on three doshas (biological energies):

Vata (air & space)

Creative, energetic but prone to dryness and restlessness. Needs warm, moist, and grounding foods.

Pitta (fire & water)

Strong digestion but prone to inflammation. Benefits from cooling, hydrating foods.

kapha (earth and water)

Stable but prone to sluggish digestion. Needs light, warm, and spicy foods.

antoine lavoisier

His work laid the groundwork for later studies on calories, metabolism, and energy balance—key concepts in nutrition and dietetics today.

idea that food provides energy through oxidation was a major breakthrough in understanding how the body functions at a molecular level.

james lind

A British naval surgeon, conducted a famous experiment in 1747 that showed the relationship between vitamin C deficiency and scurvy.

William Beaumont

treated Alexis St. Martin, a French-Canadian fur trader who suffered a gunshot wound to the stomach.studied the digestion process in the open wound, leading to groundbreaking discoveries in the mechanics of digestion and the role of stomach acid in nutrient breakdown.

casimir funk

A Polish biochemist, coined theterm vitamin" in 1912 after identifying certain essential compounds that were necessary for health.

beri beri

Caused by vitamin B1 (thiamine) deficiency

Pellagra

Later linked to niacin (vitamin B3) deficiency

Christiaan Eijkman

a Dutch

physician, demonstrated that thiamine

(vitamin B1) deficiency was the cause of beriberi. His work, later expanded by others, led to the understanding that vitamins are essential to human health.

Albert Szent-Györgyi

in the 1930s, who isolated vitamin C (ascorbic acid) from citrus fruits, furthered our understanding of its importance in preventing scurvy, as evidenced by Lind’s earlier work. Vitamin C was subsequently recognized as vital for collagen production and overall immune function.

World War I and II

the importance of nutrition became more apparent. Governments implemented rationing systems and focused on providing balanced diets for soldiers and civilians alike.

Recommended Dietary Allowances

RDA

FOOD PYRAMID

developed in 1992 by

the USDA, provided a visual guide to

balanced eating, influencing dietary

habits for generations.

It represented a shift toward

preventative nutrition, which could help

avert chronic diseases related to poor

diet.

Green Revolution: The 1960s and 1970s

witnessed the —-, a global movement that introduced high-yielding crop varieties and advanced farmingtechniques, aimed at combating world hunger. While the revolution helped increase food production, it also raised concerns about the quality of nutrition, especially in developing countries where access to diverse foods remained limited.

Obesity Epidemic: By the 1980s and 1990s

obesity

rates in both developed and

developing nations began to rise

sharply, prompting governments and

health organizations to respond with

public health campaigns.

Centers for Disease Control and Prevention

CDC

FAO

Food and Agriculture Organization

who & fao

have

begun promoting the concept of

planetary health, encouraging diets

based on plant-based foods that are

both healthy for individuals and less

damaging to the environment.

nutrigenomics

This emerging field explores

how the foods we eat

interact with our genes to influence our health.

gut microbiome

Research into the gut microbiome

has exploded in the last two

decades, showing that the trillions

of microorganisms living in our

intestines play a crucial role in

digesting food and influencing

metabolism.

global nutrition security

Today, there is a renewed focus on ensuring that nutrition is accessible to

all, particularly in low-income nations.

The Zero Hunger Challenge, established by the United Nations in 2012, aims

to address global malnutrition by improving food security and access to

essential nutrients.
