A recent study has uncovered that the quality, not just the quantity, of <keyword id="22058820" type="General" weightage="20" keywordseo="good-cholesterol" source="keywords">good cholesterol</keyword> (HDL-C) plays a critical role in a woman’s risk for Alzheimer’s disease as she transitions through <keyword id="20007297" type="General" weightage="20" keywordseo="menopause" source="keywords">menopause</keyword>. Conducted by researchers at the University of Pittsburgh, the study found that larger <keyword id="23527804" type="General" weightage="20" keywordseo="HDL-particles" source="keywords">HDL particles</keyword>, which increase during menopause, are less effective in supporting <keyword id="20068868" type="General" weightage="20" keywordseo="cognitive-health" source="keywords">cognitive health</keyword> than their smaller, phospholipid-rich counterparts. Published in the Journal of Clinical Endocrinology and Metabolism, the research demonstrates that women who maintain a higher concentration of these smaller HDL particles during midlife may be more likely to retain better episodic memory in later years. Episodic memory, or the ability to recall specific events, is often one of the first cognitive functions to deteriorate as Alzheimer’s progresses. “Even as early as midlife, we observed that women with more small, phospholipid-rich HDL particles had a better chance of preserving memory function as they aged,” explained lead researcher Samar R. El Khoudary, professor of epidemiology at Pitt Public Health, as per a report in IANS. The research team followed women over a 16-year period, from 2000 to 2016, repeatedly assessing cognitive function and tracking changes in the composition and functionality of their HDL particles. While higher levels of total HDL-C are often associated with cardiovascular benefits, the study found that as women age, the size and composition of these particles become more critical to brain health. Previous studies by the team have shown that certain health behaviours, such as adopting a balanced diet and staying physically active, can enhance the quality of HDL particles by increasing phospholipid concentrations in the bloodstream, which may help reduce Alzheimer’s risk. El Khoudary noted, “Although higher HDL-C levels might not protect against cognitive decline later in life, especially after menopause, lifestyle changes that improve the quality of these particles could be key to better brain health in the long run.” This study challenges the traditional view that higher HDL-C levels are always beneficial and introduces a more nuanced understanding of cholesterol’s role in women’s health. It highlights the importance of early intervention and lifestyle adjustments during midlife, a critical window when cognitive health can be influenced. While many women focus on managing overall cholesterol levels, this research suggests that the key to reducing Alzheimer’s risk may lie in improving the composition of HDL particles, starting as early as one’s 40s.

These dark purple berries make a great smoothie addition and have added benefits for your heart, blood-sugar control, and digestion. Here's what the research says about how acai berries may boost your <keyword id="6354750" type="UNKNOWN" weightage="100" keywordseo="health">health</keyword>. <h2>What is acai?</h2>Acai berries grow in the rainforests of<a href="https://foodrevolution.org/blog/acai-berry-benefits/" target="_blank" rel="noopener"> Central and South America</a> and have become widely available in the US. Acai berries don't last long on a shelf - they start to ferment after about 48 hours - so in American stores, you can generally find them as a powder or frozen puree.Acai berries are rich in nutrients -<a href="https://fdc.nal.usda.gov/fdc-app.html#/food-details/718602/nutrients" target="_blank" rel="noopener">100 grams of acai fruit pulp contains</a>: <ul><li>73 calories</li><li>6 grams of fat</li><li>2 gram of protein</li><li>2 grams of sugar</li><li>3 grams of fiber, 12% of your recommended dietary allowance (RDA) </li><li>Vitamin A, 25% of your RDA</li><li>Calcium, 4% of your RDAI</li></ul>Acai also contains<a href="https://womenshealth.obgyn.msu.edu/blog/science-and-acai-berry" target="_blank" rel="noopener"> anthocyanin and flavonoids</a>, compounds known for their<a href="https://www.insider.com/what-are-antioxidants-good-for"> antioxidant</a> qualities.Medical term: Antioxidants are substances that can prevent cellular damage from free radicals, which are harmful particles that may damage your DNA, contribute to harmful diseases like cancer, and accelerate aging. <h2>1. Rich in antioxidants</h2>Many fruits contain antioxidants, but acai berries stand out above the rest. In fact, 100 g of acai berries has<a href="http://www.orac-info-portal.de/download/ORAC_R2.pdf" target="_blank" rel="noopener"> ten times more</a> antioxidant capacity than the same amount of blueberries.However, because acai berries are typically available powdered or in purees, you'll need to pay attention to their sugar content. "Make sure you're buying unsweetened versions since a <keyword id="6358230" type="UNKNOWN" weightage="60" keywordseo="diet">diet</keyword> high in<a href="https://www.insider.com/what-happens-when-you-eat-too-much-sugar-2017-9" target="_blank" rel="noopener"> added sugars</a> can promote free radical production," Cassetty says.<h2>2. May help regulate blood sugar</h2>"There isn't much research on the benefits of acai berries in humans," says<a href="http://www.samanthacassetty.com"> Samantha Cassetty</a>, MS, RD, a <keyword id="52652" type="ORGANIZATION" weightage="60" keywordseo="nutrition">nutrition</keyword> and wellness expert in private practice.But<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6007924/" target="_blank" rel="noopener"> animal research</a> suggests that it may have the potential to help fight diabetes.This is partly because acai contains high levels of<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6007924/" target="_blank" rel="noopener"> polyphenol compounds</a>, which can help change the way your body digests carbohydrates and may make you feel more full.One of the few <a href="https://pubmed.ncbi.nlm.nih.gov/21569436/" target="_blank" rel="noopener">studies done in humans</a>, published in 2011, involved 10 healthy, overweight adults who took 100 mg of acai pulp twice a day for one month. After a month, the participants had significantly lower blood glucose and insulin levels, both important indicators of diabetes risk. They also had smaller blood sugar spikes after meals, suggesting that acai puree may help keep blood sugar in balance.But again, to get these positive effects, it's important to avoid sweetened acai products, which can spike blood sugar, Cassetty says.<h2> 3. May improve digestive health</h2>Acai berries may <a href="https://www.sciencedirect.com/science/article/abs/pii/S0308814617307458" target="_blank" rel="noopener">help improve</a> digestion because of their polyphenol antioxidants. "These compounds get broken down into fuel for the beneficial bacteria in your gut," Cassetty says.Having<a href="https://flexbooks.ck12.org/cbook/ck-12-middle-school-life-science-2.0/section/11.19/primary/lesson/bacteria-in-the-digestive-system-ms-ls" target="_blank" rel="noopener"> "good" gut bacteria</a> is important to help you break down food and prevent overgrowths of harmful bacteria, which can lead to digestive issues.Acai berries are also rich in<a href="https://www.insider.com/fiber-benefits" target="_blank" rel="noopener"> fiber</a>, which helps to create a diverse microbiome of gut bacteria and helps keep your stools regular.<h2>4. May support heart health</h2> Acai berries may boost heart health by balancing out your<a href="https://www.insider.com/what-is-high-cholesterol" target="_blank" rel="noopener"> cholesterol levels</a>, an important factor in controlling<a href="https://www.insider.com/what-is-heart-disease" target="_blank" rel="noopener"> heart disease</a>.In the previously mentioned small<a href="https://pubmed.ncbi.nlm.nih.gov/21569436/" target="_blank" rel="noopener"> 2011 study</a>, the participants not only had blood sugar improvements but also had reduced levels of <a href="https://www.insider.com/what-is-good-cholesterol" target="_blank" rel="noopener">LDL or "bad" cholesterol.</a> Reducing LDL is particularly important for <a href="https://my.clevelandclinic.org/health/articles/16866-cholesterol-guidelines--heart-health">lowering the risk of heart diesease.</a>Another<a href="https://pubmed.ncbi.nlm.nih.gov/28249700/" target="_blank" rel="noopener"> small study from 2018</a> found that young women who took 200 mg of acai each day for a month showed a favorable effect on the body's metabolism of HDL or "good" cholesterol. The researchers conclude that these benefits could help to fight atherosclerosis, which is a buildup of fat in arteries that can contribute to heart disease. <h2>Insider's takeaway</h2>More research is needed to understand the health effects of eating acai or using it in skin products, but there are important nutrients in acai that may be helpful to overall health.Acai berries contain potent polyphenols and antioxidants that may offer benefits for your heart, skin, blood sugar levels, and digestive system."If you want to experiment with acai powders or purees, make sure you're buying unsweetened varieties. You can add the powder to baked goods and oatmeal and the puree to smoothies and smoothie bowls," Cassetty says.<a data-type="5ff8881fc645d72fbb287ad8">6 science-backed benefits of blueberries, according to nutritionists</a><a data-type="600b6b20a07d64218e7b710e">What the research says about ginger's weight-loss benefits, and why you should be skeptical</a><a data-type="5f11f6484dca6842e105b032">4 health benefits of lemon water and how much you should drink each day</a><a data-type="5fd2a3efc7bd857bb77ccb16">What happens when you eat too much protein, and how much is healthy</a>
