Now that I am in my apartment cleaning for Passover, I can take a break and complete some posts;
I can say with confidence that past middle age hardly a person is spared from slow metabolism. It happens to women after menopause.
What didn’t surprise me was the recommendation and caution to limit gluten, fatty, sugary, and processed foods. What surprised me was the limitation of fiber. These all have an influence how your body absorbs synthroid. Older adults should take in take in 20 to 35 grams of fiber a day. Amounts of dietary fiber from whole grains, vegetables, fruits, beans, and legumes that go above that level affect your digestive system and can interfere with absorption of thyroid hormone replacement drugs.
Cruciferous vegetables, such as broccoli and cabbage, can interfere with the production of thyroid hormone, particularly people who have an iodine deficiency. Digesting these vegetables can block the thyroid’s ability to absorb iodine, which is essential for normal thyroid function.People with hypothyroidism may want to limit their intake of broccoli, Brussels sprouts, cabbage, cauliflower, kale, turnips, and bok choy. Cooking the vegetables can reduce the effect that cruciferous vegetables have on the thyroid gland. Limiting your intake to 5 ounces a day appears to have no adverse effect on thyroid function.
People with hypothyroidism should consider minimizing their intake of gluten, a protein found in foods processed from wheat, barley, rye, and other grains, says Ruth Frechman, RDN, a dietitian and nutritionist in the Los Angeles area and a spokesperson for the Academy of Nutrition and Dietetics. Gluten can irritate the small intestine and may hamper absorption of thyroid hormone replacement medication.
Fats have been found to disrupt the body’s ability to absorb thyroid hormone replacement medicines, Dr. Lee says. Fats may also interfere with the thyroid’s ability to produce hormone as well. Some health care professionals recommend that you cut out all fried foods and reduce your intake of fats from sources such as butter, mayonnaise, margarine, and fatty cuts of meat.
Hypothyroidism can cause the body’s metabolism to slow down, Frechman says. That means it’s easy to put on pounds if you aren’t careful. “You want to avoid the foods with excess amounts of sugar because it’s a lot of calories with no nutrients,” she says. It’s best to reduce the amount of sugar you eat or try to eliminate it completely from your diet.
“Processed foods tend to have a lot of sodium, and people with hypothyroidism should avoid sodium,” Frechman says. Having an underactive thyroid increases a person’s risk for high blood pressure, and too much sodium further increases this risk. Read the Nutrition Facts label on the packaging of processed foods to find options lowest in sodium. People with an increased risk for high blood pressure should restrict their sodium intake to 1,500 milligrams a day, according to the U.S. Centers for Disease Control and Prevention.
Getting enough fiber is good for you, but too much can complicate your hypothyroidism treatment. Guidelines currently recommend that older adults take in 20 to 35 grams of fiber a day. Amounts of dietary fiber from whole grains, vegetables, fruits, beans, and legumes that go above that level affect your digestive system and can interfere with absorption of thyroid hormone replacement drugs. If you’re on a high-fiber diet, ask your doctor if you need a higher dose of thyroid medication. Your maintenance dose may need to be increased if you aren’t absorbing enough medication.
Caffeine has been found to block absorption of thyroid hormone replacement, Lee says. “People who were taking their thyroid medication with their morning coffee had uncontrollable thyroid levels, and we couldn’t figure it out,” she says. “I now have to be very careful to tell people, ‘Only take your medication with water.'” You should wait at least 30 minutes after taking your medication before having a cup of joe.
Alcohol consumption can wreak havoc on both thyroid hormone levels in the body and the ability of the thyroid to produce hormone. Alcohol appears to have a toxic effect on the thyroid gland and suppresses the ability of the body to use thyroid hormone. Ideally, people with hypothyroidism should cut out alcohol completely or drink in careful moderation.
From Everyday Health.com By Dennis Thompson Jr.9 Foods to Avoid With Hypothyroidism
What you eat can affect your thyroid gland as well as your body’s ability to use thyroid hormone. Learn which foods to avoid when managing hypothyroidism. The Mayo Clinic Site also cautions about excessive dietary fiber. They suggest:
Avoid taking your thyroid hormone at the same time as:
Iron supplements or multivitamins containing iron
Antacids that contain aluminum or magnesium
Some ulcer medications, such as sucralfate (Carafate)
Some cholesterol-lowering drugs, such as those containing cholestyramine (Questran) and colestipol (Colestid)
To avoid potential interactions, eat these foods or use these products several hours before or after you take your thyroid medication.
