HEALTH BENEFITS OF CANNED SARDINES

May help improve cardiovascular health

Cardiovascular disease is the leading cause of death among adults in the United States, so efforts to reduce the prevalence of these health problems are critical. The most recent review was published in 2023. in April in the journal Frontiers in Nutrition, found that the omega-3 content of sardines has important effects on heart health and that their consumption may offer more benefits than oral supplements. Scientists are investigating the synergistic relationship between sardine omega-3 and nutrients such as calcium, potassium, magnesium, iron and zinc. When these natural nutrients work together, they can help reduce inflammation and oxidative stress in the body (oxidative stress weakens a person's immunity), promote circulation, and reduce the risk of cardiovascular disease.

May help prevent type 2 diabetes

According to the Centers for Disease Control and Prevention, about 96 million U.S. adults—that's 1 in 3—have pre-diabetes. Preventive efforts to prevent this condition from progressing to type 2 diabetes are critical, and the nutrients in canned sardines can make a big difference.

in 2021 Research published in the journal Clinical Nutrition examined the effects of consuming sardines twice a week in older adults diagnosed with pre-diabetes. In this randomized controlled clinical trial, which is considered the "gold" standard in research, researchers found that individuals who received sardines as part of their nutritional program had a significantly lower risk of developing type 2 diabetes compared to a control group who received only dietary supplements. consultations without including sardines in the diet. Participants who ate sardines also had higher levels of HDL cholesterol ("good" cholesterol) and lower triglyceride levels and blood pressure.

According to the Lithuanian Institute of Hygiene, in Lithuania in 2022 154,681 individuals had diabetes mellitus (CD) (E10–E14), ie 1 in 20 men and 1 in 17 women. The number of patients in 2014-2022. gradually increased: the number of children with CD increased by 34 percent, adults by 28.8 percent.

Type 2 CD is usually diagnosed at an older age: in men, 70-79 years. in the age group (172/1000 men), for women a little later - 75-79 years. (185/1000 women) and 80-84 years. age (182/1000 women).

Can help strengthen human bones

Protecting bone health is important for healthy human aging. Canned sardines are naturally full of calcium and vitamin D, two essential nutrients that play an important role in maintaining bone health. in 2017 Research published in the Journal of Osteoporosis shows that insufficient intake of important macro and micronutrients such as calcium and vitamin D can negatively affect bone health and prolong the time it takes for the body to repair bones after injuries in the elderly. Other studies have also highlighted the beneficial effects that the nutrient composition of fish such as sardines can have in the treatment of hip fractures.

Certified nutritionist Lauren Manaker, MS, RDN, LD , agrees that encouraging Americans to eat more sardines could benefit bone health. She states: “Many canned sardine products are pitted, which can be an added nutritional benefit. Those small bones are full of calcium and vitamin D, which play an important role in maintaining bone health as people age."

Osteoporosis is an important health problem in Lithuania as well, especially among older people. According to the data of the Lithuanian Department of Statistics, osteoporosis is often diagnosed only after bone fractures, as the disease can progress for a long time without any symptoms. in 2023 according to data, about 50% of women and 25% of men over 50 years of age suffer from an increased risk of bone fractures.

Lithuanian health specialists emphasize that the main risk factors for osteoporosis are immutable, such as age and heredity, but poor nutrition and lack of physical activity also play an important role. It is especially important to ensure a sufficient amount of calcium and vitamin D in the diet, because the lack of these trace elements contributes to the decrease in bone density.

May support brain health

The cognitive health benefits of omega-3 fatty acids have received much attention over the years. in 2018 A review published in the journal Nutrients evaluated the results of 25 randomized control trials that examined the role of omega-3 supplements in brain health across the lifespan. The researchers found that people who supplemented their diets with DHA and EPA (two types of omega-3s) showed improved blood biomarkers that resulted in health benefits regardless of age. Higher omega-3 intake also improved mental ability in school-aged children and cognitive function in older adults.

Although there is a growing body of evidence supporting the benefits of omega-3 supplements, nutritionists recommend that consumers consider their diet first. Dietitian Lauren Manaker, MS, RDN, LD, says, “Eating canned sardines may have positive effects on cognitive health. They're also a great way to increase your DHA intake, given that most Americans don't get enough of this important fatty acid in their diets."
