The small intestine contains small finger-like projections of tissue called villi which increase the surface area of the intestine and contain specialized cells that transport substances into the bloodstream. Although these villi do not aid in the digestion of nutrients, they do help with nutrient absorption.
Fresh fruits and vegetables can become contaminated before or after harvest. Contaminated seeds, irrigation water, and flooding have contributed to Salmonella outbreaks traced to sprouts, lettuce, and other fresh produce. Unpasteurized orange juice has been the source of several Salmonella outbreaks. Water intended for recreation (e.g., pools, shallow lakes) and for human consumption can also become tainted with Salmonella. When lakes become contaminated with Salmonella, several weeks or months can be required for water quality conditions to improve or return to normal.
Salmon is also a wonderful source of vitamins D and B-12, selenium and protein. Aim to eat a 6-ounce fillet of salmon two to four times a week to reap these many health benefits. Get the Recipe: Roasted Salmon with Shallot Grapefruit Sauce.
