You are what you eat and what you eat impacts your mental well-being.
You can adjust serotonin, a brain chemical linked with depression, by varying the amount of carbohydrates in your diet.
When you get depressed, the brain triggers a craving for the very carbohydrates that are capable of restoring serotonin to normal levels. In other words, food affects your mood and your mood influences which foods you choose.
Of all the nutritional options available, one is guaranteed to improve your health and enable you to live longer—eat less. Dr. Robert Good has conducted research that shows in both animals and humans that reducing caloric intake improves just about all aspects of the immune system.
Not only that, but illnesses stemming from an unbalanced immune system become easier to manage.
No one is certain of why this happens although the most likely explanations involve a reduction in lifetime exposure to free radicals and an increased desire to exercise.
Whenever you reach a point during a meal when you want more but it would mean seconds or thirds, push the plate away. You’ll be exactly where you need to be for optimal health.
By eating the right foods, you might be able to lessen your susceptibility to stress. Ultramarathoners are significantly more vulnerable to upper respiratory infection compared with moderate exercisers. Studies have revealed that when marathoners ingest 5-6 percent liquid carbohydrate, it reduces the stress-induced rise in cortisol.
The same procedure also blocks some of the immune system changes normally associated with excessive exercise. While more research is needed, it is quite possible that the consumption of carbohydrates may reduce other consequences of stress-induced cortisol production.
