"Our brain requires a constant supply of fuel. That “fuel” comes from the foods we eat — and what’s in that fuel makes all the difference.
Put simply, what we eat directly affects the structure and function of our brain."

Not all foods come with nutrition labels. There are many websites and phone apps which provide nutritional value of foods, including restaurant food. Perhaps the easiest way to find basic nutrition information is do a search in a web browser, like Google, or Safari, DuckDuckGo, Bing etc. For example, a search like "carrots nutrition" or "carrots nutrients" or "glazed carrots nutrition" will find reliable information. Results may vary depending on site or amount but generally you'll find they're all in the ballpark.
Search for restaurant foods this way as well, i.e. "Olive Garden chicken cacciatore nutrition." This works for the well known chain restaurants dishes and check their own websites as well.
