You will increase your risks of many age-related chronic diseases such as cancers, dementia, osteoporosis, heart disease, etc. Imperfect diets won’t supply all the nutrients we believe we needed (US RDAs) to live a longer more productive life. The foods we choose to eat (along with physical activity or lack thereof) are a major contributing factor in why some people get these diseases early in life and others much later or never. The foods we eat contain our micronutrients including vitamins, minerals, carotenoids, etc., that make up all the parts of the body and allow it to function properly. If we fall short, we are simply not made to last or function our best. As examples: If our calcium & vitamin D intake regularly fall short, it leads to weaker bones that break early. If we regularly fall short of B vitamins, omega 3 fatty acids and/or certain carotenoids, brain, heart and visual functions may be compromised earlier than if we consumed proper amounts throughout life. To make matters worse is the fact that you never really know if you are getting, or can get, everything from the foods you choose, which is why we recommend you eat the best you can (pick one of our very healthy diets on the Sharecare MILI platform) and take a daily multivitamin & mineral formula to cover all your bases.
