The food we consume has an impact on our mood and personality. Several studies have found that consuming poor or less nutritious foods might cause anxiety, sadness, mood changes, and other problems. You will experience highs and lows. There will be days when you eat absolutely clean and nutritious, and days when you consume two or three cookies. This is normal. The more serious aspect of this relationship involves malnutrition. If you don't get enough nutrients, it will affect how you think and act. Studies have shown that people who were given low-calorie diets lost weight but also became anxious and depressed. The same thing happens when you drink alcohol or use drugs. Your body needs nutrients to work properly. If you don't give it what it needs, it will take its toll on your mind and body. Eating well means eating healthy foods that provide you with all the nutrients you need for energy, vitality, and growth. It also means avoiding unhealthy options even if you feel like having them. Going back for seconds or thirds of a snack isn't going to help you achieve your goal weight or change your personality. Finally, food affects your personality due to the effect it has on your hormones. Eating too much or in general poor nutrition can cause levels of insulin and other hormones such as cortisol to rise excessively. This can have an overall negative effect on your mood and ability to deal with stressors in your life.
