Review
Plant oils have been utilized for a variety of purposes throughout history, with their integration into foods, cosmetics, and pharmaceutical products. They are now being increasingly recognized for their effects on both skin diseases and the restoration of cutaneous homeostasis. This article briefly reviews the available data on biological influences of topical skin applications of some plant oils (olive oil, olive pomace oil, sunflower seed oil, coconut oil, safflower seed oil, argan oil, soybean oil, peanut oil, sesame oil, avocado oil, borage oil, jojoba oil, oat oil, pomegranate seed oil, almond oil, bitter apricot oil, rose hip oil, German chamomile oil, and shea butter). Thus, it focuses on the therapeutic benefits of these plant oils according to their anti-inflammatory and antioxidant effects on the skin, promotion of wound healing and repair of skin barrier.

Mediterranean diet: The role of long-chain ω-3 fatty acids in fish; polyphenols in fruits, vegetables, cereals, coffee, tea, cacao and wine; probiotics and vitamins in prevention of stroke, age-related cognitive decline, and Alzheimer disease.
The mechanisms of action of the dietary components of the Mediterranean diet are reviewed in prevention of cardiovascular disease, stroke, age-associated cognitive decline and Alzheimer disease. A companion article provides a comprehensive review of extra-virgin olive oil. The benefits of consumption of long-chain ω-3 fatty acids are described. Fresh fish provides eicosapentaenoic acid while α-linolenic acid is found in canola and soybean oils, purslane and nuts. These ω-3 fatty acids interact metabolically with ω-6 fatty acids mainly linoleic acid from corn oil, sunflower oil and peanut oil. Diets rich in ω-6 fatty acids inhibit the formation of healthier ω-3 fatty acids. The deleterious effects on lipid metabolism of excessive intake of carbohydrates, in particular high-fructose corn syrup and artificial sweeteners, are explained. The critical role of the ω-3 fatty acid docosahexaenoic acid in the developing and aging brain and in Alzheimer disease is addressed. Nutritional epidemiology studies, prospective population-based surveys, and clinical trials confirm the salutary effects of fish consumption on prevention of coronary artery disease, stroke and dementia. Recent recommendations on fish consumption by pregnant women and potential mercury toxicity are reviewed. The polyphenols and flavonoids of plant origin play a critical role in the Mediterranean diet, because of their antioxidant and anti-inflammatory properties of benefit in type-2 diabetes mellitus, cardiovascular disease, stroke and cancer prevention. Polyphenols from fruits and vegetables modulate tau hyperphosphorylation and beta amyloid aggregation in animal models of Alzheimer disease. From the public health viewpoint worldwide the daily consumption of fruits and vegetables has become the main tool for prevention of cardiovascular disease and stroke. We review the important dietary role of cereal grains in prevention of coronary disease and stroke. Polyphenols from grapes, wine and alcoholic beverages are discussed, in particular their effects on coagulation. The mechanisms of action of probiotics and vitamins are also included.

This study was aimed to assess the effect of membrane structure on the stability of peanut oil bodies extracted by enzyme-assisted extraction. The influence of pH, NaCl concentration, and temperature on the physicochemical properties of peanut oil bodies was characterized using ζ-potential and particle size. The results indicated that the peanut oil bodies had strong stability (ζ-potential, >20 mV) at pH values away from the isoelectric point (pH 4.8), at a low salt concentration (NaCl concentration, <10 mM), and in a certain temperature range (35 to 55 °C). The stable structure of the oil body was closely related to its structure. Phospholipids, along with membrane proteins, were major components of the oil body membrane. Therefore, the phospholipid composition and content were measured and the types of membrane proteins of the oil bodies were identified. The results showed that phosphatidylcholine and phosphatidylserine were major components of the oil body phospholipids. Two-dimensional electrophoresis showed that the oil bodies contained both intrinsic proteins and extrinsic proteins, which might play an important role in the stability of oil bodies during enzyme-assisted extraction processing.

Annals of Allergy, Asthma & Immunology... Sep 2019To review the cost-effectiveness of food allergy management strategies. (Review)
Review
OBJECTIVE
To review the cost-effectiveness of food allergy management strategies.
DATA SOURCES AND STUDY SELECTIONS
A narrative review and synthesis of literature identified using a PubMed search of relevant articles describing cost-effectiveness evaluations of food allergy management.
RESULTS
Screening at-risk infants for peanut allergy carries risk of overdiagnosis and is not cost-effective. Evidence suggests that cost-effective care could be better optimized by minimizing delay in oral food challenges for eligible patients, clarifying the role of precautionary allergen labeling, incorporating patient-preference sensitive care in activation of emergency medical services for resolved allergic reactions, and considering value-based pricing and school-supply models for epinephrine. Finally, the annual value-based cost (willingness to pay [WTP] $100,000/quality-adjusted life years [QALY]) of peanut immunotherapy has been estimated to be between $1568 and $6568 for epicutaneous immunotherapy (EPIT) and between $1235 and $5235 for probiotic with peanut oil immunotherapy (POIT), with each therapy showing more favorable cost-effectiveness with greater improvements in health utility, particularly if sustained unresponsiveness can be achieved.
CONCLUSION
Many aspects of food allergy management are not cost-effective, and recent evaluations suggest a greater role for incorporating patient and family preferences into guideline-based and traditionally reflexive management decisions. Caregiver understanding of food allergy screening tradeoffs is critical, given that screening children before allergen exposure has significant costs and results in overdiagnosis, especially when oral food challenges are omitted from diagnostic algorithms. Cost-effectiveness analysis can help to identify important decision levers in patient management across a wide range of topics. Further research is needed to better understand health state utilities of specific patient populations.

Review
BACKGROUNDS
One of the common consumed snacks among Iranian is nuts. The aim of this systematic review was to determine the rate of peanut contamination with aflatoxin B1 (AfB1) in different provinces of the Iran.
MATERIALS AND METHODS
The research studies with keywords "aflatoxin B1", "peanut", "peanut butter", "peanut oil", "coated peanut", "roasted peanut", "snack peanut" were searched in PubMed, Scopus, Science Direct, Google Scholar and scientific information databases (SID), regardless of publication time. A total of 43 studies were obtained and only six articles were finally selected according to exclusion and inclusion criteria. Margin of Exposure (MOE) and Hazard Quotient (HQ) were also calculated to evaluate the oral exposure of AfB1 through peanuts and peanut-based products.
RESULTS
The contamination of AFB1 in peanut was high in Mashhad and Tehran compared with the other cities. The value of MOE was calculated less than 10,000. The results of MOE indicate that there are chances of the risk of developing cancer and these products may not be safe. Therefore, AFB1 levels should be measured regularly in peanut products in large cities.

Review
In comparison with protein, dietary fat receives little attention in the food system sustainability literature, although we calculate that the average consumption of fats in many populous regions of the world is below nutritional recommendations. Animal products are the major source of dietary fat, particularly in regions with excess fat consumption. We estimate that an additional 45 Mt of dietary fat per year need to be produced and consumed for the global population to reach recommended levels of fat consumption, and we review different strategies to fill this gap sustainably. These strategies include diverting oils currently used for energy production to human consumption, increasing palm oil and peanut oil yields while avoiding further deforestation, developing sustainable cropping systems for the production of rapeseed and soybean oils, increasing the consumption of whole soybeans and derived products, and expanding the use of animal fats already produced.

In this study, we investigated immunoreactivity of peanut (Arachis hypogaea) oil using the silkworm (Bombyx mori) model. The peanut oil induced melanin formation when injected to the silkworm hemocoel. We then purified the active substance and identified the triacylglycerols (TAGs) as the responsible molecule for the melanin-forming effect of peanut oil. Also, the peanut TAGs induced the muscle contraction of the silkworm (i.e., cleavage of the insect cytokine BmPP) and the TNF-α production by cultured mouse macrophage cells. The muscle contraction activity of the peanut TAGs was reduced by saponification reaction, indicating that the TAG (not the degraded fatty acids) moiety is responsible for the activity. The muscle contraction effects of other TAGs of olive, lard, and beef oil were comparable with that of peanut TAGs. Nevertheless, for the melanin formation, the effect of peanut TAGs was outstanding. The fatty acid composition of peanut TAGs was distinct from that of olive TAGs. These results suggest that TAGs are immunoreactive and induces cytokines both in insect and mammalian immune systems. Also, the differential effects of peanut and olive TAGs for the melanin formation may suggest that TAGs with different fatty acid compositions are distinguished by the immune system.

The solubility and physicochemical properties of resveratrol in peanut oil were systematically studied following ultrasonic and magnetic stirring-assisted dissolution. The highest resveratrol solubility in peanut oil observed was 95.91%. The optimal dissolution process was determined to be the addition of 183.00 mg/kg resveratrol, a magnetic temperature of 40.00℃, and a magnetic duration of 3.50 h, which yielded a resveratrol content of 175.51 mg/kg oil. Under this standardized process, the oil composition remained unchanged. Resveratrol promoted the conversion of saturated triglycerides into unsaturated triglycerides, increased the linolenic acid content, and did not facilitate the formation of trans fatty acids. In addition, resveratrol preservedthe lightcolor, decreased the peroxide and acid values by 30%, prolonged the shelf life by more than 2 folds, and improved the thermal stability. In this sense, peanut oil with resveratrol can serve as anti-isomerism and antioxidant additive.

HYPOTHESIS
Can vegetable oils containing long-chain triglycerides be aerated to yield stable oil foams? This is based on the idea that cooling of vegetable oil results in the formation of crystals of certain triglyceride chain lengths and composition dispersed in liquid oil of other chain lengths and composition. Do such oleogels allow the formation of oil foams stabilised by adsorbed crystals?
EXPERIMENTS
Using two vegetable oils, the temperatures for crystal formation are determined. Crystal dispersions were characterised using rheology and optical microscopy. Oleogels were aerated using a double beater and the effects of temperature and aeration time were investigated. The stability and microstructure of the oil foams were studied visually and using microscopy. A stable oil foam was progressively destabilised on heating.
FINDINGS
Upon cooling/warming vegetable oils, crystals of high melting triglyceride form in a low melting liquid oil - an oleogel. Such oleogels can be whipped to fabricate oil foams stabilised by fat crystals. Optimum foaming yields an over-run of ~ 40% for peanut oil and ~ 110% for olive oil. Oil foams which do not exhibit drainage, coarsening or coalescence result. We show that high melting triglyceride crystals possess a higher fraction of saturated fatty acids than the original oil. Ultra-stable oil foams can be rendered unstable by heating upon approaching the melting point of the crystals.

Review
Peanuts () can be made into various products, from oil to butter to roasted snack peanuts and candies, all from the kernels. However, the skin is usually thrown away, used as cheap animal feed, or as one of the ingredients in plant fertilizer due to its little value on the market. For the past ten years, studies have been conducted to determine the full extent of the skin's bioactive substance repertoire and its powerful antioxidant potential. Alternatively, researchers reported that peanut skin could be used and be profitable in a less-intensive extraction technique. Therefore, this review explores the conventional and green extraction of peanut oil, peanut production, peanut physicochemical characteristics, antioxidant activity, and the prospects of valorization of peanut skin. The significance of the valorization of peanut skin is that it contains high antioxidant capacity, catechin, epicatechin resveratrol, and procyanidins, which are also advantageous. It could be exploited in sustainable extraction, notably in the pharmaceutical industries.
