Elimination diets … Fish oil and heart arrythmia
Q: What is an elimination diet? Can it be used for weight loss?
A: Alicia Romano, MS, RD, CSNC, a registered dietitian/nutritionist with the Frances Stern Nutrition Center who specializes in gastrointestinal diseases and food allergies, answers: “I’m glad you asked this question! Elimination diets are sometimes used as diagnostic or treatment tools. They are not for weight loss.
Using common items makes it easy to know how much food you’re really eating.
Vitamin B9 is one of eight B (B-complex) vitamins that help your body change food (carbohydrates) into fuel (glucose) to produce energy. You need B9 for the health of your liver, skin, hair and eyes, and to keep your nervous system working properly.
Cleveland Clinic – Vitamin B9 helps your body make healthy new cells, supporting many of its functions, and may help prevent health issues from developing. It’s proven critical for reproductive health, too.
“It’s essential for people who are pregnant to take folic acid supplements to support healthy fetal growth and development,” notes Zumpano. “When you’re trying to conceive or are pregnant, it’s extremely difficult to get the amount of vitamin B9 needed.”
Studies show that people who take folic acid supplements before conception and during the first trimester of pregnancy may reduce their risk of having children with neural tube defects (birth defects of the brain and spine such as spina bifida) by 40% to 80%. Early evidence suggests folic acid may also be associated with a lower risk of autism, severe language delays and emotional issues.
Front-of-package health claims can be helpful—but they can also be misleading. Learn how to tell the difference.
A study that followed nearly 400,000 middle-aged individuals in the U.K. for a median of over 10 years found that, compared to individuals who reported drinking less than one cup of coffee a day, drinking four or more eight-ounce cups a day was associated with lower risk of 30 medical conditions.
The U.S. Food and Drug Administration (FDA) recently proposed new draft guidelines for food manufacturers who want to label their products as “healthy.” This term was last defined in the 1990s. According to the FDA, “our current definition permits manufacturers to use the claim ‘healthy’ on some foods that, based on the most up-to-date nutrition.

Consuming just a half-tablespoon or more of olive oil a day is linked to a lower risk of dying from heart disease and other chronic health conditions, new research suggests.
The study included more than 92,000 women and men from the Nurses’ Health Study and the Health Professionals Follow-up Study, who filled out diet questionnaires every four years for 28 years. Olive oil intake was calculated from how much they reported using in salad dressings, on bread and other food, and in baking or frying.
Compared with participants who rarely or never consumed olive oil, those who consumed the most (about a half-tablespoon or more daily) had a 19% lower risk of dying from heart disease during the study. Researchers also noted lower death rates over all among people who substituted olive oil for a similar amount of margarine, butter, mayonnaise, or dairy fat. The findings, published Jan.18, 2022, in the Journal of the American College of Cardiology, lend further support for choosing olive oil — a key component of the heart-friendly Mediterranean diet.
Some attention and planning may be necessary to ensure popular diet plans provide enough of all the nutrients you need.

Anyone who has ever had a kidney stone never wants a repeat of the blinding pain that comes when it passes. Now, a new study maps out a diet that can help guard against that.
The cornerstones of that diet include eating plenty of foods that contain potassium, as well as a few servings of low-fat dairy daily, to get enough calcium. High-potassium fruits and veggies that could help include bananas, oranges, grapefruits, apricots, mushrooms, peas, cucumbers, zucchini, and melons such as cantaloupe and honeydew.
To arrive at those recommendations, researchers from the Mayo Clinic used data from questionnaires completed by kidney stone patients between 2009 and 2018. The team compared the diets of 411 people who had already had their first kidney stone and a control group of 384 individuals.
“We had this information and then we, number one, could look at things that … differed between controls and kidney stone formers, but then we’ve also been following these people forward in time,” said study author Dr. John Lieske, director of the O’Brien Urology Research Center at the Mayo Clinic in Rochester, Minn.
During a median of just over four years of follow-up, 73 patients in the study had recurrent kidney stones.
Lower levels of calcium and potassium predicted that recurrence. After adjustments for non-dietary factors, lower calcium continued to be a predictor. So did lower potassium, but only among those who weren’t already taking certain types of diuretics and calcium supplements.
ess than 7% of the U.S. adult population has good cardiometabolic health, a devastating health crisis requiring urgent action, according to research led by a team from the Friedman School of Nutrition Science and Policy at Tufts University in a pioneering perspective on cardiometabolic health trends and disparities published in the July 12 issue of the Journal of the American College of Cardiology. Their team also included researchers from Tufts Medical Center.
Researchers evaluated Americans across five components of health: levels of blood pressure, blood sugar, blood cholesterol, adiposity (overweight and obesity), and presence or absence of cardiovascular disease (heart attack, stroke, etc.). They found that only 6.8 percent of U.S. adults had optimal levels of all five components as of 2017-2018.
