Regular peanut consumption appears to positively influence lipid metabolism, reducing levels of triglycerides in the blood.
In the ARISTOTLE study, a randomized control trial was conducted with 63 participants who consumed either 25g/day of skin roasted peanuts, two tablespoons of peanut butter per day, or two tablespoons per day of a control butter based on peanut oil alongside their usual diet for a period of 6 months. This was done to understand the impact of regular peanut consumption on anthropometric, biochemical, and clinical measurements. Additionally, a meta-analysis was carried out incorporating data from several clinical trials, including the aforementioned ARISTOTLE study, to further consider the effects of consuming peanuts and peanut butter in both healthy individuals and those at a high cardiometabolic risk.
The findings from the ARISTOTLE study indicated that lower total cholesterol/HDL-cholesterol and LDL-cholesterol/HDL-cholesterol ratios were observed in the group consuming skin roasted peanuts compared to the control butter group. Furthermore, the meta-analysis of clinical trials highlighted an association between peanut consumption and a decrease in triglycerides. It was seen that healthy consumers had lower total cholesterol and LDL-cholesterol/HDL-cholesterol ratios compared to control groups. However, it was also discovered that individuals at a high cardiometabolic risk experienced an increase in body weight following the peanut interventions, despite no change in body fat or body mass index. From the dose-response analyses, it was inferred that body weight slightly escalated with higher dosages of peanuts.

Oat consumption can significantly improve lipid profiles, particularly reducing total cholesterol and LDL cholesterol, with potential positive effects on triglycerides and HDL cholesterol under certain conditions.

Systematic Review Cholesterol HDL-C Oats
In the methodology of this review study, information was gathered from various databases, including PubMed, Web of Science, and Google Scholar. The gathered data consisted of a total of 17 studies that explored the direct effects of oat consumption on lipid profiles. The focus of the studies included were the impacts of oat on levels of total cholesterol, VLDL, LDL-C, TG, and HDL-C. The review was meticulous, with a detailed examination of each study, particularly those showing positive effects of oat/beta-glucan consumption on triglycerides.
The review's results revealed that oat intake significantly reduces the levels of total cholesterol, VLDL, and LDL-C. The effect of oat ingestion on triglyceride levels was varied; of the 17 studies, 6 reported a decrease in triglycerides. Interestingly, one study showed an improvement in HDL-C levels following oat consumption. It was also observed that oat intake might effectively reduce triglycerides in healthy individuals and overweight people or those with diabetes or metabolic syndrome, especially when larger amounts of oat were consumed over a longer duration or in conjunction with a calorie-reducing diet. The use of oat together with certain dietary programs was suggested to potentially enhance its positive effects on lipid profiles.
Pomegranate consumption positively affects triglycerides, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol levels.

Systematic Review Cholesterol Pomegranate Triglyceride
To investigate the impact of pomegranate on lipid profiles, a comprehensive database search was completed up until June 2023, aiming to identify related trials. Statistically, the researchers employed the estimated 95% confidence and the weighted mean difference to measure the variables, including triglycerides, total cholesterol, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol. They employed a random-effects model for their analysis.
The meta-analysis revealed that pomegranate intake significantly reduces triglyceride levels. Still, it doesn't notably alter the total cholesterol concentrations. Additionally, consuming pomegranate seemed to have a diminishing impact on low-density lipoprotein cholesterol levels and an enhancing effect on high-density lipoprotein cholesterol levels.
Regular nut consumption, particularly peanuts and walnuts, is associated with a lower incidence of frailty in aging female populations.

Cohort Study Anti-Ageing Frailty Peanut
The methodology of the study includes a population-based observational study of nonfrail women aged 60 and above from 11 states across the US, from the Nurses' Health Study. The outcome focused on incidence of frailty, defined through the FRAIL components such as fatigue, lower strength, reduced aerobic capacity, multiple chronic conditions, and significant weight loss. These were assessed every four years from 1992 to 2016. Food Frequency Questionnaires were used to examine the intake of peanuts, peanut butter, walnuts, and other nuts every four years from 1990 to 2014. Total nut consumption was calculated and categorized into varying serving sizes, and the relation of intake of each type of nut with frailty was examined separately using Cox proportional hazard models, adjusted for various factors such as age, smoking, BMI, diet quality, and medication use.
In discussing the results, out of 71,704 participants, 14,195 frailty cases arose over a million person-years. Notably, regular consumption of nuts, particularly peanuts and walnuts, showed a significant inverse relation with frailty. That is, a higher intake of these types of nuts were associated with lower cases of frailty. However, the same didn't apply to peanut butter. This affirms the potential benefits of regular nut consumption in aging female population's health and well-being.
Almond intake significantly changed the concentrations of triglycerides, total cholesterol and low-density lipoproteins

Systematic Review Almond Cholesterol Triglyceride
To estimate the overall effect of almond intake, we employed the random-effect model. In total, 27 studies with 36 effect sizes were included in our analysis (1154 cases and 904 control subjects). The meta-analysis revealed that almond intake significantly changed the concentrations of triglycerides, total cholesterol, and low-density lipoproteins; however it did not have a significant effect on high-density lipoprotein levels. Meta-regression analysis indicated a linear relationship between the dose of almond and change in TG. This meta-analysis concludes that almond intake can significantly reduce lipid parameters.
Chocolate and cocoa product consumption significantly improved lipid profiles, but had no significant effect on other heath aspects such as cognitive function and blood pressure.

Systematic Review Chocolate Cocoa Triglyceride
A systematic search was performed on academic databases such as MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials. The researchers utilized a precise search strategy and keywords to gather the most relevant studies and evidence. The studies focused on a variety of health effects related to the consumption of chocolate and cocoa products, like their effects on skin, cardiovascular health, anthropometry, cognitive function, blood glucose levels, and overall quality of life.
The research revealed considerable improvements in lipid profiles (particularly in triglycerides) among those who consumed chocolate or cocoa products, compared to controls. However, there were no significant differences observed in other outcome parameters related to skin health, blood pressure, cognitive function, anthropometry, blood glucose levels, and quality of life between the chocolate/cocoa consumption group and the control group. The subjects generally accepted chocolate well, with gastrointestinal disturbances and unpalatability reported as their main concerns.
