Presently, modern lifestyle diseases (LSD) such as cancer, diabetes, hypertension, cardiovascular disease, thyroid etc., 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, wheat etc. are grown with the application of agrochemicals (e.g., glyphosate) whose traces comes 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 nutrition value of food gets compromised due to low dietary fiber content and synthetic additives, e.g., sucralose (artificial sweetener), which promotes inflammation and weakens our immune system, due to which our body becomes 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., long 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, sustain‐released, etc. With the help of nanotechnology, we can get nutritional and agrochemical‐free food.
