Nutrition and dietary habits impact brain health and immunity

Nutrition plays a critical role in maintaining bodily functions and the immune system. Cardiologist Aurelio Rojas highlights the importance of egg consumption for brain health, particularly for individuals over 60. He notes that the numbers on eggshells indicate the hens' rearing systems: numbers starting with 3 indicate caged hens, while 1 indicates free-range and 0 indicates organic. Eggs from hens that graze in sunlight contain higher levels of omega-3, vitamin D, and antioxidants, which may help reduce cognitive decline.

Rojas also emphasizes the importance of choline, a nutrient essential for producing acetylcholine, a neurotransmitter vital for memory and learning that often declines with age.

Additionally, dietary choices can strengthen the immune system, which relies heavily on nutrition. Bone broths made from chicken, beef, or pork bones, combined with vegetables like carrots, celery, and onions, are recommended as a way to provide essential vitamins and minerals to support the body during respiratory illnesses.
