简要总结
The objectives of this trial are to assess the effects of adding 2 servings/d of either full-fat or low-fat fermented dairy products to the diet, as a replacement for non-dairy foods with macronutrient composition similar to the low-fat fermented dairy condition, on insulin sensitivity, erythrocyte fatty acid profile and other cardiometabolic health markers in metabolically at-risk adults.

入选标准
- •Subject is 18-74 years of age, inclusive.
- •Subject has a BMI of 25.00 kg/m2 to 39.99 kg/m2 at screening (visit 1b).
- •Subject has a fasting TG level ≥135 mg/dL at screening (visit 1a), or a fasting TG level 122-134 mg/dL (inclusive) and a fasting venous TG level of ≥135 mg/dL at screening (visits 1a and 1b, respectively).
- •Subject has a rating of 7 to 10 on the Vein Access Scale at screening (visit 1b; Appendix 2).
- •Subject is judged by the Investigator to be in general good health on the basis of medical history and screening laboratory tests.
- •Subject is willing to maintain usual physical activity pattern throughout the study and is willing to refrain from vigorous physical activity for 24 h prior to each clinic visit.
- •Subject has no plans to change smoking habits during the study and is willing to abstain from tobacco products and caffeine use 1 h prior to and during each clinic visit.
- •Subject is willing to refrain from using marijuana and consuming alcoholic beverages for 24 h prior to each clinic visit.
- •Subject is willing to consume study-related foods and follow the dietary instructions throughout the 12-week treatment period.
- •Subject is willing to come to the clinic for study food pick-up(s) if needed.
- •Subject understands the study procedures and signs forms documenting informed consent to participate in the study and authorization for release of relevant protected health information to the study Investigator and is willing to complete study procedures.
排除标准
- •Subject has a laboratory test result of clinical significance at screening (visit 1b).
- •Subject has fasting blood glucose ≥126 mg/dL at screening (visit 1a) or known type 1 or type 2 diabetes mellitus.
- •Subject has atherosclerotic cardiovascular disease including any of the following: clinical signs of atherosclerosis including peripheral arterial disease, abdominal aortic aneurysm, carotid artery disease [symptomatic (e.g., myocardial infarction, angina, transient ischemic attack or stroke of carotid origin) or >50% stenosis on angiography or ultrasound] or other forms of clinical atherosclerotic disease (e.g., renal artery disease).
- •Subject has a history or presence of a clinically important medical condition that, in the opinion of the investigator, could interfere with the interpretation of the study results.
- •Subject has uncontrolled hypertension (systolic blood pressure ≥160 mm Hg or diastolic blood pressure ≥100 mm Hg) at screening (visit 1b).
- •Subject has a history of cancer in the prior 5 years, except for non-melanoma skin cancer or carcinoma in situ of the cervix.
- •Subject has experienced a change in body weight of ±4.5 kg (10 pounds) over the 3 months prior to screening (visit 1b).
- •Subject has unstable use (initiation or dose alteration) of any antihypertensive medication within 4 weeks prior to screening (visit 1b).
- •Subject has unstable use (initiation or dose alteration) of any of the following lipid-altering medications within 4 weeks prior to screening (visit 1b): statins, ezetimibe, bempedoic acid, bile acid sequestrants, fibrates, niacin (drug form), and/or omega-3 fatty acid drugs.
- •Subject has unstable use (initiation or dose alteration) of a proprotein convertase subtilisin kexin type 9 (PCSK9) inhibitor within 3 months of screening (visit 1b).
- •Subject has unstable use (initiation or dose alteration) of weight-loss drugs (including over-the-counter medications and/or supplements) and/or systemic corticosteroid drugs within 4 weeks of screening (visit 1b).
- •Subject has unstable use (initiation or dose alteration) of medications known to influence carbohydrate metabolism, including, but not limited to: adrenergic receptor blockers, thiazide diuretics, hypoglycemic medications, and/or antipsychotics within 4 weeks prior to screening (visit 1b).
- •Subject has an active infection or has used antibiotics within 5 d of any clinic visit. Those with an active infection and/or using antibiotics must wait at least 5 d after the infection resolves or antibiotic use is complete. The test period will be extended for completion in these cases.
- •Subject has a known allergy, sensitivity, or intolerance to any ingredients in the study foods. Mild lactose intolerance is not exclusionary.
- •Subject is a female, who is pregnant, planning to be pregnant during the study period, lactating, or is of childbearing potential and is unwilling to commit to the use of a medically approved form of contraception throughout the study period.
- •Subject has extreme dietary habits (e.g., vegan or very low carbohydrate diet).
- •Subject has a current or recent history (past 12 months), or strong potential, for drug or alcohol abuse. Alcohol abuse is defined as >14 drinks per week (1 drink = 12 oz beer, 5 oz wine, or 1 ½ oz distilled spirits).
- •Subject has a history of a diagnosed eating disorder (e.g., anorexia nervosa or bulimia nervosa).
- •Subject has been exposed to any non-registered drug product within 30 d of screening (visit 1b).
- •Subject has a condition the Investigator believes would interfere with his or her ability to provide informed consent or comply with the study protocol, or which might confound the interpretation of the study results or put the person at undue risk.
