How Global Diet Link Environmental Sustainability And Human Health?

A person’s diet is the total amount of food and drinks they consume regularly. Diets are transforming in various ways throughout the world, mainly due to changing lifestyle according to research. In certain regions of the globe, international food supply patterns are encouraging better diets, while in others, they are creating underweight and obesity. They’re also having a big impact on the environment’s long-term viability, which might be problematic. A global diet concept was created to enable a healthy global population. The phrase “global diet” is meant to indicate the development of a diet that focuses on human health and also sustainability.

Everyone would be aware of the correlation between diet and human health, but we must not miss the impact of global diets on the environment. Thus giving thought to sustainable diets that suits current lifestyle becomes essential. The environmental impact of agricultural practices and scarcity of food is not a new visual. Dietary characteristics relate to environmental sustainability and human health in a variety of ways.

People’s diets mirror the times and circumstances in which they live. Urbanization is a relatively new phenomenon in history. As a result of the industrial revolution, people’s lifestyles have changed, and many, if not all, of them, now live in cities rather than in the countryside.

People’s levels of physical activity, body composition and physique, life expectancy, and disease patterns, including cancer, are all affected by the diverse food systems and diets that are part of these varied ways of life. Obesity, type 2 diabetes, coronary heart disease, and even some cancers are more prevalent in city dwellers.

Human Health And Global Diet

Health is more than just the absence of sickness or physical fitness. As such, a state of entire bodily, mental, and social well-being might be defined. Healthier people are more productive at work. Health also extends people’s lives and minimises new-born and child mortality also maternal death rate. Healthy body can be achieved by lifestyle changes and following  a proper global diet regime.

Tragically, today’s globe has become accustomed to a food consumption system that has several negative consequences for human health. We have been motivated so much by lifestyle changes that we have very little time to consider whether or not what we are eating is a healthy diet! Globalization has had a significant impact on people’s eating patterns, forcing many to consume upscale, high-calorie quick meals, sometimes referred to as “fast food.”

Obesity, food poisoning, dehydration, and heart difficulties are all examples of illnesses. Diabetes mellitus and arthritis are on the rise in developing nations, and eating unhealthy junk food, processed meals, and an excessive amount of fat calories are all contributing factors. We need to follow a global diet scheme that is also focused on improving human health.

Major Aspects Of Global Diet

The following major issues concerning the link between global diet and health must be addressed.

Adequate Nutrition: NutritionDeficiencyis caused due to undernutrition and overnutrition results in hypertension, cardiovascular diseases, diabetes and cancer. It also emphasises that the body’s dietary requirements may differ depending on the individual with different heredity and family backgrounds, different dietary habits, and living in different countries ,following different lifestyles.

Building Immunity: A prime role of nutrition is in providing immunity to fight against diseases. Hypo-immunity is only observed in infants, children, and the elderly and individuals with diseases and serious nutrition defects. Excessive immunity can induce inflammation, autoimmune disorders, and metabolic disorders when nourish ent is available, even if it is redundant. Immunity, like a two-edged sword, may cause illnesses when it is either low or too high.

Public health: It’s a social and political idea intended at enhancing people’s health, extending their lives, and increasing their quality of life through health promotion, illness prevention, and other means of medical intervention. It is meant to ensure a thorough awareness of how behaviours and living environments influence health, as well as a realisation of the need to mobilise resources and make wise decisions investments in policies, programmes, and services that lead to the creation of supporting healthy lifestyles and maintaining and protecting one’s health.

Sustainability And Global Diet

The environment, economy, health, nutrition, and other associated factors all fall under the umbrella of sustainability. Sustainability is a complex topic in which the food production system and our eating habits play critical roles. Achieving a healthy and sustainable food future is a pressing issue that will require worldwide cooperation and development of a global diet.

According to FAO’s definition: “Sustainable Global  Diets are those diets with low environmental impacts that contribute to food and nutrition security and healthy life for present and future generations. Sustainable diets are protective and respectful of biodiversity and ecosystems, culturally acceptable, accessible, economically fair and affordable; nutritionally adequate, safe and healthy; while optimizing natural and human resources”.

Environmental Impacts Of Global Diet

The EAT-Lancet Commission identifies a set of boundaries that global diet should stay within to “decrease the risk of irreversible and potentially catastrophic shifts in the Earth system,” as current food production is driving climate change, biodiversity loss, pollution, and unsustainable changes in water and land use. These lines correspond to six major earth system processes: Changes in the climate (based on greenhouse gas emissions), land system change (based on cropland usage), freshwater usage, biodiversity loss (based on extinction rate), and nitrogen and phosphorus cycle are all factors to consider (based on the application of these fertilizers).

Switching To Plant-Based Food

Global Diet

Many individuals in middle- and high-income nations, as well as richer individuals in developing nations, consume far more meat and other animal-source foods than is necessary for sustenance alone, putting human and environmental health at risk. Much of it is generated in an unsustainable manner. As many species are fished to critical limits or beyond, overfishing threatens not just our fish stocks, but also the entire ecosystems of the seas. Too many of the crops we consume are produced on newly converted land and are not subject to nature-friendly production techniques that safeguard soil and water quality — for future growth and all the other advantages they provide, such as carbon sequestration.

Plant-based foods have a lesser environmental effect than animal-based diets. As a result, we may lower our environmental footprint as a global society by increasing the amount of plant-based goods we consume, as long as they are available, inexpensive, and meet the nutritional needs of each individual. Many communities value sustainably produced meat and fish as important sources of sustenance, and in some cases, they may also help with landscape management and ecosystem services. Switching to plant based food forms an essential part of global diet development.


Despite a growing body of research relating diets to human health and environmental sustainability, there has historically been a dearth of universally agreed-upon standards for healthy eating and sustainable food production.

Establishing an environmentally sustainable system while focusing on health is a pressing issue that necessitates joint efforts from governments, the private and public sectors, and individuals. A combined effort by an inclusive involvement of global diet is an essential step towards achieving sustainability and improving human health.
