How To Speed Up Your Metabolism With Food

Metabolism is defined as the rate at which the body uses glucose for energy. Metabolism is controlled by an endocrine, or hormone-secreting gland, called the thyroid. The thyroid secretes the hormones T3 and T4, which are made in part from a mineral called iodine, to control metabolism in the body. A thyroid condition called hypothyroidism exists when the thyroid gland under-produces these hormones, resulting in a slow or sluggish metabolism. Foods that support the thyroid gland and increase metabolism are those rich in iodine and other nutritive minerals which support thyroid function.

Step 1

Include a healthy amount of iodized salt in the diet. According to the University of Maryland Medical Center, iodized salt is the main source of dietary iodine in the standard American diet. The recommended daily amount of iodine suggested for adults aged 18 and up is 120 to 150 mcg per day. Keep in mind that too much salt, or sodium, in the diet can have adverse effects such as weight gain and water retention.

Step 2

Consume marine foods such as plant and animal life. Seafood and sea vegetables such as kelp, shellfish and deep water fish are a dietary source of iodine. According to the Linus Pauling Institute of Oregon State University, one quarter ounce of dried seaweed may contain as much as 4,500 mcg of iodine, so consumption is not needed in large amounts to get enough iodine in the diet. Cod fish contains about 100 mcg per three ounces of meat.

Step 3

Eat other foods that are a dietary source of iodine to boost thyroid function and metabolism. Foods that include dietary iodine include garlic, lima beans, sesame seeds, soybeans, spinach, Swiss chard, summer squash, turnip greens, cow's milk, navy beans, potato with the skin on and turkey breast. Including these foods in your diet regularly can ensure healthy levels of iodine in the body and well-maintained thyroid function.
