Daily avocado consumption improves attentional inhibition and increases serum lutein concentrations, irrespective of changes in lutein status, in adults with obesity.
The study involved a randomized-controlled trial with 84 adults aged 25-45 years suffering from overweight or obesity. The participants were divided into a treatment group and a control group. Those in the treatment group consumed a daily meal with fresh Hass avocado for 12 weeks while the control group was given an isocaloric meal. The xanthophyll status was evaluated by measuring serum lutein and macular pigment optical density, and cognitive functions such as attention and inhibition were evaluated using the Flanker, Oddball, and Nogo tasks.
Regarding the results, the treatment group showed improved serum lutein concentrations and better performance in the Flanker task demonstrating improved attentional inhibition. However, they found no correlation between improvements in performance and changes in lutein status and no significant changes in macular pigment optical density. Therefore, it suggests that the cognitive benefits from avocado intake were not due to changes in lutein status but may involve other unknown mechanisms.

The discussion of the results reveals that almond consumption has been found to create favorable alteration in aspects like body weight, food intake, blood pressure, blood lipid composition, glucose, and insulin levels, as well as oxidative status, liver enzymes, and inflammation biomarkers. These findings highlight the beneficial impact of almonds on multiple health issues including cardiovascular diseases, diabetes, and obesity. Additionally, the consumption of almonds has been associated with improved cognitive performance and protection against skin photodamage and aging.
Consumption of one avocado per day can potentially reduce visceral adiposity and subsequently decrease the risk of diabetes and cardiovascular disease.
2021 Contemporary Clinical Trials The design and rationale of a multi-center randomized clinical trial comparing one avocado per day to usual diet: The Habitual Diet and Avocado Trial (HAT) Reboussin DM, Kris-Etherton PM, Lichtenstein AH, Li Z, Sabate J, Matthan NR, et al.
Randomised Controlled Trial Avocado Cardiometabolic Disease Cardiovascular Disease
The Habitual Diet and Avocado Trial was a multicenter, randomized, controlled study that evaluated the impact of daily avocado consumption over a period of six months. The experiment involved a large and diverse cohort. Participants were required to incorporate a daily avocado into their diet as a substitute for their regular dietary intake, notably those devoid of avocado consumption. Their progress was measured using magnetic resonance imaging (MRI) to ascertain the potential decrease in visceral adiposity, with individuals with increased waist circumference being the primary focus of the study. Additional measures such as hepatic lipid content, plasma lipid profiles, blood pressure and high sensitivity C-reactive protein were also part of the evaluation.
The study showed promising results in terms of weight control and reduction of visceral adiposity among participants. Initial results suggest that the sense of satiety post avocado consumption may subsequently lead to an overall decrease in energy intake. Moreover, the daily consumption of avocados was observed to not only reduce visceral fat but also display potential benefits impacting cardiometabolic disease risk. The benefits of avocado consumption were notably apparent among a cohort with an increased waist circumference, thus confirming the potential health benefits of avocados in weight management and risk reduction of obesity-related diseases.
Avocado, with its lipid-lowering, antihypertensive, antidiabetic, anti-obesity, and cardioprotective effects, can potentially manage metabolic syndrome more efficaciously than synthetic treatment options.

Systematic Review Avocado Cardiovascular Disease High Blood Pressure
The methodology used in this research involved a systematic review of several studies investigating the pharmacological effects of avocado on different components of metabolic syndrome. This included studies on the lipid-lowering, antihypertensive, antidiabetic, anti-obesity, antithrombotic, antiatherosclerotic, and cardioprotective effects of avocado. Further, the review also encompassed researches based on the effects of avocado's various parts like the flesh, seed, peel, and leaves in metabolic syndrome.
Upon evaluation of collected studies, the researchers found that the avocado, a rich source of carotenoids, minerals, phenolics, vitamins, and fatty acids, demonstrates strong potential in managing metabolic syndrome. Its antidiabetic, antihypertensive, anti-obesity, lipid-lowering, and cardioprotective properties specifically align with the key risk factors of metabolic disease, including high blood sugar, dyslipidemia, hypertension, and obesity. These qualities suggest that avocado might present a more efficient and less adverse alternative to synthetic treatments.
