In fact, that accumulation is the hallmark of atherosclerosis. As the study authors point out, many other studies have found that polyphenols help prevent that accumulation, likely by helping circumvent that oxidation process.Īccording to the Harvard T.H. The reason why it's useful as a marker is that increased LDL oxidation is actually what causes cholesterol to accumulate in the arteries, according to a 2021 paper published in Current Molecular Pharmacology. LDL oxidation is one of those aforementioned markers of cardiovascular disease risk, according to Future Medicine. At the end of the study period, blood tests revealed LDL cholesterol that was 20% more resistant to oxidation than it had been when first measured at the start of the study. It even cites a 2000 study in which healthy adults drank 12 ounces of clear apple juice for a period of six weeks. Likewise, Healthline points out that scientific literature is rife with studies demonstrating that the polyphenols contained in apple juice (and particularly cloudy apple juice, for the reasons discussed above) can support cardiovascular health. So, you can see how that might add up rather quickly, which is why Samantha Cassetty, RDN, recommends limiting consumption to one cup per day (per Well+Good).

As discussed above, a one-cup serving of 100% apple juice delivers somewhere in the vicinity of 24 grams of fructose. Those health conditions include all of the various conditions associated with metabolic syndrome, such as 'insulin resistance, elevated triglycerides, abdominal obesity, elevated blood pressure, inflammation, oxidative stress, endothelial dysfunction, microvascular disease, hyperuricemia, glomerular hypertension and renal injury, and fatty liver.'Īccording to the authors of the 2008 meta-analysis, it would appear that one can safely consume up to 90 grams of fructose per day. Although it is a naturally occurring form of sugar found in fruit, fructose is associated with a number of negative health conditions when consumed in excess, according to a 2008 meta-analysis published in the American Journal of Clinical Nutrition.
