They are one of the best dietary sources of vitamin A, which promotes healthy skin, coat, eyes, nerves, and muscles in dogs. Vegetables with orange flesh contain beta-carotene, a precursor of vitamin A and a powerful antioxidant that helps prevent disease and infection.
Sweet potatoes are also a rich source of fiber, vitamins C and B6, potassium, calcium, and iron, among many other essential vitamins and minerals.
In addition, sweet potatoes are often added to pet foods and treats because they are gentle on a dog’s digestive system and naturally gluten-free. They’re a common ingredient in grain-free canine diets because they provide an alternative source of carbohydrates.
Pet owners should consult a veterinarian before feeding sweet potatoes to dogs, as too much vitamin A can cause bone problems and muscle weakness. And while they are lower on the glycemic index than white potatoes, you should still speak with your vet first if your dog has a health condition such as diabetes.
Yellow split peas are a particularly excellent food source of B vitamins and several minerals essential for human health. Yellow split peas are rich in two of the energy-yielding nutrients: protein and carbohydrates, meeting on average 20 and 10 percent, respectively, of the recommended daily value or DV for a 2,000 calorie diet. Though split peas do not contain all of the essential amino acids necessary for human health, such as animal proteins, they are particularly rich in the amino acid tryptophan, meeting over 1/4 of your daily requirement in a 1/2-cup serving. Tryptophan is needed to manufacture the neurotransmitter or brain chemical serotonin, which regulates mood, appetite, hunger and sleep.
Yellow split peas are particularly rich in vitamin B-1 or thiamin, providing approximately 0.18 milligrams per 1/2-cup serving or 12 percent of the DV and 64 micrograms folate, or 16 percent of the DV. In addition to aiding in energy metabolism or converting the foods you eat into energy for your cells, thiamin is needed for proper nervous system function.
Like beans, split peas are a mineral-dense food, according to the USDA National Nutrient Database. Split peas offer phosphorus and potassium, meeting about 10 percent of the DV for each per 1/2-cup serving. Phosphorus, along with calcium, is a major mineral involved in developing strong, healthy bones. It is also a component of all cells and DNA. Potassium helps regulate heartbeat and blood pressure and promotes healthy arterial circulation. Split peas are high in the trace minerals molybdenum and manganese, which are involved in metabolic reactions in the body.
A 1/2-cup serving of cooked split peas offers 7 grams of insoluble fiber or "roughage" and 3 grams of soluble or viscous fiber. Both types are important for optimal health. Insoluble fiber promotes healthy digestion, softens stool and encourages regular bowel movements, while soluble fiber offers other benefits.
