An interventional study of Pomegranate Juice and Placebo Juice in Erythema and Inflammation, sponsored by University of California, Los Angeles. Terminated at 1 site in United States. Open to male participants aged 18 Years to 65 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2021-04-19.

This study will determine the effects of beneficial compounds of plant foods, such as pomegranate on cardiovascular health, skin inflammation and aging. This will be tested by asking healthy males to eat a high fat ground beef patty with 8oz. pomegranate juice or 8oz placebo (a study product that looks like pomegranate juice, but contains no active ingredients) and then measuring blood vessel dilation (endothelial function) by blood flow. The investigators also will measure the amount of Nitric Oxide (NO) in blood and urine samples and sugar and insulin in blood. In addition, a Cutometer, a device that measures the elasticity of the skin, will be used to obtain measurements of skin inflammation and aging.
Healthy men have been chosen for this study because eating high fat hamburger patties can easily mimic in them the condition that causes atherosclerosis. The results from this study may help to explain how high fat foods can be harmful to the body and how beneficial plant foods can have on cardiovascular function and the skin.
The proposed investigation has two major objectives: 1. to determine the clinical efficacy of pomegranate juice to reduce skin aging by assessing UV-induced change and skin biological characteristics of elasticity, sebum, hydration/moisture and systemic inflammation and 2. To determine the impact of pomegranate polyphenols on the metabolic response to a high fat meal by postprandial flow-mediated dilation and plasma nitric oxide. The investigators propose to achieve the following specific aims in a randomized, two arm, parallel intervention of pomegranate juice or placebo for 12 weeks in obese men.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
A “mini-stroke”: temporary stroke-like symptoms caused by reduced blood flow to part of the brain, spinal cord or eye, without signs of a new stroke on a scan.
Stroke symptoms need emergency care at once, even if they go away.
A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.
Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

Postprandial high fat meal will be administered with pomegranate juice with the first dose of the intervention, Pomegranate Juice , followed by 12 weeks of pomegranate juice consumption.
Other: Pomegranate Juice
Postprandial high fat meal will be administered with pomegranate juice with the first dose of the intervention, Placebo Juice , followed by 12 weeks of pomegranate juice consumption.
Other: Placebo Juice
After the one week run-in period of consuming an ellagitannin-free diet, participants will undergo the skin testing followed by the postprandial meal test with a high fat (HF) test meal consumed with the first dose of the intervention (Pom J or placebo). For the next 12 weeks, participants will consume a daily dose of pomegranate juice 1x/day. During week 4 participants will undergo another skin testing. During week 12 participants will undergo another skin testing and postprandial meal challenge. Stool will be collected at week 1, 4 and 12.
