Applications of nanotechnology to combat the problems associated with modern food

Abstract

Currently, modern lifestyle diseases (LSD) such as cancer, diabetes, hypertension, cardiovascular and thyroid disease are commonly seen among people of different age groups. One of the root causes of this LSD is the type of food that we are eating. Staple crops like rice, sugarcane, vegetables and wheat are grown with the application of agrochemicals (e.g., glyphosate), traces of which are found in our food; after that, it gets ultra‐processed in factories; e.g., chips and snacks are fried using saturated fats (trans fat); sugar and wheat (derivatives bread, buns, cookies) are processed using toxic chemicals (bleaching agents). As a result, the nutritional value of food is compromised due to low dietary fiber content and synthetic additives – e.g., sucralose (artificial sweetener) – which promotes inflammation and weakens our immune system, causing our body to become sensitive to microbial infection and many other LSDs. To strengthen the immune system, people start taking synthetically prepared supplements and drugs for a prolonged time, which further deteriorates the body organs and their normal function; e.g., prolonged medication for hypothyroidism poses a risk of heart attack and joint pain. Nanotechnology solves the above problems in the food, nutraceuticals and agriculture sectors. Nanotechnology‐based naturally processed products such as nano‐nutraceuticals, nanofood, nanofertilizers and nanopesticides will benefit our health. They possess desirable properties such as high bioavailability, targeted delivery, least processing and sustained release. With the help of nanotechnology, we can get nutritional and agrochemical‐free food. © 2022 Society of Chemical Industry.

Unveiling the Future: Nanotechnology's Role in Advanced Food Packaging

“…2). The incorporation of active polymer nanoparticles into the packaging material has garnered considerable attention, with the capability to encapsulate various bioactive compounds, improving their bioavailability and safeguarding their stability during storage, transit, and consumption (Singh and Packirisamy 2023).…”

Mitigating the Impacts of the COVID-19 Pandemic on Crop Farming: A Nanotechnological Approach

“…For instance, precision farming aims at the targeted delivery of nano agrochemicals, thereby improving nutrient-use efficiency, crop production and yield, plant resilience, and soil health. Nanotechnology-based processes such as nano-nutraceuticals and nanofood are emerging to increase the nutrient quality of crop yield, provide physiological health benefits, and enhance protection against chronic diseases [33]. Nanotechnology can also be applied to food packaging to improve its shelf life and maintain freshness for extended periods.…”

Green Routes for Bio-Fabrication in Biomedical and Pharmaceutical Applications

“…To realize vectors for nutraceuticals encapsulation and delivery, it is possible to use proteins, polysaccharides, or lipids because they are abundant, sustainable, and non-toxic. Multiple edible delivery systems have been developed for nutraceutical applications, including particles, emulsions, films, and hydrogels, to improve the solubility of active ingredients, avoid interactions with the food matrix before consumption, and control their release [ 157 ].…”
