There is no successful treatment for Alzheimer's disease to this day that makes it necessary to reduce its occurrence rather than treat the disease after it has occurred. Therefore, it became necessary and priority to focus on preventing it and knowing the causes that lead to the deterioration of the brain after it was fully active and strong. Back in the early stages of brain development in which food plays an important role. The focus comes on the important elements and materials that increase intelligence, skills, brilliance of thinking and memory, which continue with the person throughout his life after feeding him with important functional elements and vitamins. It is noted that with the development and increase of processed and refined food items that have recently entered the human body, there has been a significant increase and acceleration in the incidence of Alzheimer's disease at alarming and frightening rates. It has become worth reconsidering what we eat and focusing on the right food and its goal as one of the factors affecting the health of brain cells. Therefore nutritional awareness has become essential and nutritional supplementation is essential for a certain age as a fighter and as a preventer before contracting the disease.

INTRODUCTION As it is known that the brain is the collector of all the qualities that characterize our humanity. It is the most complex part of the human body and the source of intelligence, the interpreter of the senses, the initiator of body movement, and the observer of behavior. Research in neuroscience and behavioral sciences and the development of new research techniques have helped understand how a healthy brain works [1-3], how to maintain its health, and what happens when the brain is diseased or dysfunctional [4, 5]. As we know that food has an important role in the development of brain development since childhood, but with the spread of brain diseases and memory deficiency with age, research continues to this day in search of an approach to combating the disease of the century; Alzheimer's disease (AD). The storm that engulfs the nerve cells in the brain, the death of their tissues, which leads to personality changes and severe deterioration in memory and mental abilities, gradually increases until one becomes completely unable to perform the simplest daily tasks with age [6, 7]. Since the brain is the control center of the body, Responsible for maintaining the heartbeat, breathing of the lungs, and allowing the body to move, feel and think, it is important to keep the mind elevated. The foods we eat play a big role in maintaining brain health from birth, and can improve some mental tasks, such as memory, focus, language, etc. Thus, brain development continues gradually with age and improves its performance. What we see today from a wide range of processed foods invading homes, shops and cafes, including sweets, creams, processed and refined starches is far from the foods that are required that boost the immunity of the human body and develop its brain, and that are required to build a strong body and strong mind [8]. It has been observed in recent years the prevalence of deterioration and atrophy of the brain with age, which leads to cell death in a group of people but not others. Unfortunately, there is no definitive cure for this cerebral deterioration to this day [9]. Given that the nature of food has a fundamental and important role in the formation of nerves, brain growth, strengthening its work, developing its skills in different life stages, activating
