Pomegranate extract consumption improves antioxidant levels, reduces oxidative stress and cardiovascular risk factors including blood pressure and body fat, and increases lean body mass.
2022 Antioxidants Antioxidant Properties and Beneficial Cardiovascular Effects of a Natural Extract of Pomegranate in Healthy Volunteers: A Randomized Preliminary Single-Blind Controlled Study Al-Dujaili EAS, Casey C, Stockton A
Randomised Controlled Trial Cardiovascular Disease High Blood Pressure Pomegranate
In the study, 24 healthy participants were divided into two groups: one consumed a natural standardized pomegranate extract, while the other, a placebo, in a randomized, single-blind placebo-controlled trial. Evaluations were conducted at baseline and post 14 and 28 days of the experiment, with variables including anthropometric measurements, blood pressure, pulse wave speed, body composition, as well as the levels of salivary and urinary cortisol, cortisone, total phenolics, antioxidant capacity, and lipid peroxidation.
The results indicated significant increases in urinary total phenolics excretion and antioxidant capacity after 14 and 28 days of pomegranate extract intake. By day 28, notable decreases were noted in systolic and diastolic blood pressure, pulse wave velocity, body fat and fat mass, and an increase in lean body mass. In terms of glucocorticoid levels, there was a marked decrease in saliva cortisol at day 28 in the morning for the pomegranate extract group, along with a decrease in the cortisol/cortisone ratio following 28 days of pomegranate extract intake at morning, noon, and evening. Reductions were also seen in urine free cortisol levels by day 14. These observations were unique to the pomegranate extract group, with no significant changes noted in the placebo group.
Coconut water and coconut milk ameliorate the negative impacts of heat stress on gastrointestinal health by reducing oxidative stress and suppressing inflammatory responses.
2022 Journal of Food Biochemistry Effect of coconut water and milk on heat stress‐induced gastrointestinal tract dysmotility in rats: Role of oxidative stress and inflammatory response Ajeigbe KO, Oladokun OO, Owonikoko MW, Adegoke GA
Experimental Study Coconut Milk Coconut Water Digestive Health
The study enlisted four different temperature exposure groups of rats, namely a control group at 30 degrees Celsius, a heat-stressed group exposed to an ambiance of 40 degrees, a heat-stressed group pre-treated with coconut water, and a heat-stressed group with coconut milk. Measurements such as skin and rectal temperatures, as well as evaluations of gastrointestinal motility factors such as intestinal transit, intestinal fluid accumulation, and colonic motility, were taken before and after a two-hour heat exposure over 14 days.
Noticeable increases in gastrointestinal motility factors were observed amongst the heat-stressed rats. However, the introduction of coconut milk and water appeared to reverse these increases. Furthermore, the elevated cortisol levels and intestinal lipid peroxidation in the heat-stressed rats were significantly reduced with the introduction of both coconut products. Likewise, results showed an increase in antioxidant enzyme activities in the rats that received either coconut water or milk, in contrast to the control group. Similarly, the coconut water and milk were seen to suppress inflammatory cytokines while enhancing others. The study also noted significant improvements in intestinal morphology among heat-stressed rats treated with either coconut product.

Systematic Review
Twelve studies with 2867 participants were included. A significant difference was observed for the relief of anxiety comparing acupuncture with controls during IVF treatment. No significant difference was found for clinical pregnancy rate. Only 2 out of 12 studies assessed remission of depression but there was no clear effect shown for acupuncture.
Ginger honey supplementation does not reduce cortisol levels, however, it significantly increases glutathione and estrogen levels in test mice.
2021 Gaceta Sanitaria Ginger honey affects cortisol, estrogen and glutathione levels; preliminary study to target preconceptional women Usman AN, Raya I, Yasmin R, Aliyah , Dirpan A, Arsyad A, et al.
Experimental Study Female Fertility Ginger Honey
The methodology involved an in vivo pretest-posttest control group design study conducted on 2-3 month old female Balb/c mice, selected due to not having experienced conception. These mice were split into a negative control and an intervention group, the latter receiving 28mg/20g body weight of ginger honey for 14 days. Prior to the supplementation, the mice were subjected to swimming-induced stress. Cortisol, glutathione, and estrogen levels were assessed using the ELISA testing method.
In the discussion of results, the findings indicated that 14 days of ginger honey supplementation did not significantly affect cortisol levels in the female mice. Contrastingly, a considerable boost was observed in both glutathione and estrogen levels. This suggests a potential role for ginger honey supplements as complementary therapies, though not for the management of cortisol-related stress.

Randomised Controlled Trial Cholesterol CRP Testosterone
The study created two matched groups of fit elderly men and placed one on a diet inclusive of walnuts (15g/day for six weeks) alongside their concurrent (resistance and endurance) training. The other group did the concurrent training without the walnut-supplemented diet. The study then took fasting blood samples from the participants 48 hours before and after the intervention for biochemical assessments.
The group consuming walnuts saw a significant improvement in their lipid profiles with increased high-density lipoprotein levels and decreased total cholesterol, low-density lipoprotein and triglyceride levels. The walnut-eating participants also saw an increase in testosterone levels after the training, which was significantly higher than the group not consuming walnuts. Additionally, the walnut-consuming group experienced lowered cortisol levels and decreased C-reactive protein compared to the group not consuming walnuts. It is plausible the results could be attributed to the presence of polyunsaturated fatty acids in walnuts.

A Randomised Controlled Trial published in 2020 in the journal European Journal of Integrative Medicine found that Intranasal application of essential oils such as lavender and fennel (Pinetonina™) significantly lowers cortisol levels and improves sleep quality. The study included 45 participants divided into three groups: one group received a saline nasal spray (Group 1 CTRL), the second group received a 30% concentration of Pinetonina™ in a buffered vehicle as an intranasal spray (Group 2 P30), and the third group received a 50% concentration of the same (Group 3 P50). The sprays were used once daily before bedtime for three months. The study measured salivary cortisol levels both at the beginning and end of the trial and assessed subjects' quality of sleep, anxiety levels, perceived stress, and overall quality of life using self-reported questionnaires. The study found that the groups using the 30% and 50% Pinetonina™ solutions saw significant reductions in their cortisol levels after the three-month period. The subjects in the 50% Pinetonina™ group also reported a notable improvement in their quality of sleep. However, there were no significant differences among the groups' perceived stress levels and their overall quality of life. Nevertheless, the study concluded that nightly intranasal use of Pinetonina™ could effectively lower cortisol levels and enhance sleep quality.
A Randomised Controlled Trial published in 2014 in the journal Endocrine Abstracts found that Pomegranate extract intake, rich in biophenols, lessens salivary cortisol levels, hence potentially improving health-related quality of life, particularly in stress-suffering individuals. The study was conducted using a double-blind, randomized, placebo-controlled parallel trial. Participants, ranging in age and body mass index, took either a pomegranate extract capsule or a placebo each day for a duration of 4 weeks. The extracted capsule, which contained a high concentration of biophenols, was consumed with water after a meal. In addition to tracking dietary practices and habits, health related Quality of Life was recorded before and after the study. To assess the effects, salivary cortisol and cortisone levels were measured at three distinct points in the day. In the results, there was a notable decrease in the salivary cortisol levels of participants who consumed these pomegranate extract capsules. Alongside this, the ratio of cortisol to cortisone was significantly minimized. The participants' physical and social functionality, pain levels, and overall well-being showed significant improvement during the study. Conversely, there was a slight increase in the salivary cortisol and ratio of cortisol to cortisone for participants who took the placebo.
