Diet and nutrition

۞وَهُوَ ٱلَّذِيٓ أَنشَأَ جَنَّٰتࣲ مَّعۡرُوشَٰتࣲ وَغَيۡرَ مَعۡرُوشَٰتࣲ وَٱلنَّخۡلَ وَٱلزَّرۡعَ مُخۡتَلِفًا أُكُلُهُۥ وَٱلزَّيۡتُونَ وَٱلرُّمَّانَ مُتَشَٰبِهࣰ ا وَغَيۡرَ مُتَشَٰبِهࣲۚ كُلُواْ مِن ثَمَرِهِۦٓ إِذَآ أَثۡمَرَ وَءَاتُواْ حَقَّهُۥ يَوۡمَ حَصَادِهِۦۖ وَلَا تُسۡرِفُوٓاْۚ إِنَّهُۥ لَا يُحِبُّ ٱلۡمُسۡرِفِينَ

It is He who produces both trellised and untrellised gardens, date palms, crops of diverse flavours, the olive, the pomegranate, alike yet different. So when they bear fruit, eat some of it, paying what is due on the day of harvest, but do not be wasteful: God does not like wasteful people

۞يَٰبَنِيٓ ءَادَمَ خُذُواْ زِينَتَكُمۡ عِندَ كُلِّ مَسۡجِدࣲ وَكُلُواْ وَٱشۡرَبُواْ وَلَا تُسۡرِفُوٓاْۚ إِنَّهُۥ لَا يُحِبُّ ٱلۡمُسۡرِفِينَ

Children of Adam, dress well whenever you are at worship, and eat and drink [as We have permitted] but do not be extravagant: God does not like extravagant people

وَكُلُواْ مِمَّا رَزَقَكُمُ ٱللَّهُ حَلَٰلࣰ ا طَيِّبࣰ اۚ وَٱتَّقُواْ ٱللَّهَ ٱلَّذِيٓ أَنتُم بِهِۦ مُؤۡمِنُونَ

but eat the lawful and good things that God provides for you. Be mindful of God, in whom you believe

وَمَآ أَرۡسَلۡنَا قَبۡلَكَ مِنَ ٱلۡمُرۡسَلِينَ إِلَّآ إِنَّهُمۡ لَيَأۡكُلُونَ ٱلطَّعَامَ وَيَمۡشُونَ فِي ٱلۡأَسۡوَاقِۗ وَجَعَلۡنَا بَعۡضَكُمۡ لِبَعۡضࣲ فِتۡنَةً أَتَصۡبِرُونَۗ وَكَانَ رَبُّكَ بَصِيرࣰ ا

No messenger have We sent before you [Muhammad] who did not eat food and walk about in the marketplace. But We have made some of you a means of testing others- will you stand fast? Your Lord is always watching

وَقَالُواْ مَالِ هَٰذَا ٱلرَّسُولِ يَأۡكُلُ ٱلطَّعَامَ وَيَمۡشِي فِي ٱلۡأَسۡوَاقِ لَوۡلَآ أُنزِلَ إِلَيۡهِ مَلَكࣱ فَيَكُونَ مَعَهُۥ نَذِيرًا

They also say, ‘What sort of messenger is this? He eats food and walks about in the marketplaces! Why has no angel been sent down to help him with his warnings

وَظَلَّلۡنَا عَلَيۡكُمُ ٱلۡغَمَامَ وَأَنزَلۡنَا عَلَيۡكُمُ ٱلۡمَنَّ وَٱلسَّلۡوَىٰۖ كُلُواْ مِن طَيِّبَٰتِ مَا رَزَقۡنَٰكُمۡۚ وَمَا ظَلَمُونَا وَلَٰكِن كَانُوٓاْ أَنفُسَهُمۡ يَظۡلِمُونَ

We made the clouds cover you with shade, and sent manna and quails down to you, saying, ‘Eat the good things We have provided for you.’ It was not Us they wronged; they wronged themselves

O children of Adam! Put on your adornment at every place of prostration. In the tongue of learning, this is the curtaining of the pudendum during the prayer. In the tongue of unveiling, the adornment of every servant is in the station of contemplating the heart's presence, clinging to the Presence, and the continuity of witnessing the Haqiqah. It has been said that the adornment of the worshiper's soul is the traces of prostration, and the adornment of the recognizer's heart is the lights of finding. The worshiper has the attribute of servanthood in the prostration, and the recognizer is on the carpet of proximity in the repose of witnessing.

And He it is Who produces creates gardens orchards trellised extending along the ground as in the case of watermelons and untrellised rising upwards on a stem such as palm-trees; and He produces palm-trees and crops diverse in flavour diverse in the shape and savour of its fruit and seed and olives and pomegranates alike in terms of their leaf mutashābihan ‘alike’ is a circumstantial qualifier and unlike in terms of their savour. Eat of the fruit thereof when it ripens before its maturity passes and pay the due thereof the alms as appropriate on the day of its harvest read yawma hasādahu or yawma hasādihi that is one tenth or half of it and do not be prodigal by giving it all away so that nothing remains for the consumption of your dependants. Truly God does not love the prodigal who overstep the bounds of that which He has delimited for them.

O Children of Adam! Don your adornment that which covers your nakedness at every place of worship at prayer and at the circumambulation and eat and drink what you want but do not be excessive; He truly does not love those who are excessive.

And it is He Who produces gardens Ma'rushat and not Ma'rushat, and date palms, and crops of different shape and taste, and olives, and pomegranates, similar, and different. Eat of their fruit when they ripen, but pay the due thereof on the day of their harvest, and waste not by extravagance. Verily, He likes not the wasteful (141)And of the cattle (are some) for burden and (some smaller) for Farsh. Eat of what Allah has provided for you, and follow not the footsteps of Shaytan. Surely, he is to you an open enemy (142) Allah Created the Produce, Seed Grains and Cattle Allah states that He created everything, including the produce, fruits and cattle that the idolators mishandled by their misguided ideas, dividing them into various designated parts, allowing some and prohibiting some. Allah said, وَهُوَ الَّذِي أَنشَأَ جَنَّاتٍ مَّعْرُوشَاتٍ وَغَيْرَ مَعْرُوشَاتٍ (And it is He Who produ

And eat of the lawful and good food which God has provided you halālan tayyiban ‘lawful and good food’ is the direct object and the preceding genitive construction mimmā ‘of … which’ is a circumstantial qualifier connected to the former; and fear God in Whom you are believers.

O you who believe! Make not unlawful the good things which Allah has made lawful to you, and transgress not. Verily, Allah does not like the transgressors (87)And eat of the things which Allah has provided for you, lawful and good, and have Taqwa of Allah in Whom you believe (88) There is No Monasticism in Islam Ali bin Abi Talhah said that Ibn 'Abbas said, "This Ayah [5:87] was revealed about some of the Companions of the Prophet ﷺ who said, 'We should cut off our male organs, abandon the desires of this life and travel in the land, just as the Ruhban (monks) do.' When the Prophet ﷺ heard of this statement, he summoned them and asked them if they made this statement and they answered 'Yes.' The Prophet ﷺ said, لٰكِنِّي أَصُومُ وَأُفْطِرُ، وَأُصَلِّي، وَأَنَامُ، وَأَنْكِحُ النِّسَاءَ، فَمَنْ أَخَذَ بِسُنَّتِي فَهُوَ مِنِّي، وَمَنْ لَمْ يَأْخُذْ بِسُنَّتِي فَلَيْسَ مِنِّي (I fast and

Narrated Abu Tha'labah Al-Khushani:"I said: 'O Messenger of Allah! We are a people who hunt.' He said: 'If you send your dog and you mentioned the Name of Allah upon it, and he catches something for you, then eat it.' I said: 'Even if he kills it?' He said: 'Even if he kills it.' I said: 'We are a people who shoot (at game).' He said: 'What you catch with your bow, then eat it.'" He said: "Then I said:'Indeed we are a people who travel. We come across Jews, Christians, and Zoroastrians, and we do not find vessels other than theirs.' He said: 'If you do not find other than them, then wash them with water, then eat and drink from it

والميل إذا لم يكن لا يمكن اختراعه واكتسابه بمجرد الإرادة بل ذلك كقول الشبعان نويت أن أشتهى الطعام وأميل إليه أو قول الفارغ نويت أن أعشق فلانا وأحبه وأعظمه بقلبى فذلك محال

ثم ينبغي أن يرفع اليد قبل الشبع ومن فعل ذلك استغنى عن الطبيب وسيأتي فائدة قلة الأكل وكيفية التدريج في التقليل منه في كتاب كسر شهوة الطعام من ربع المهلكات

ثم إن الشهوة لو لم تسكن عند أخذ مقدار الحاجة من الطعام، لأسرفت وأهلكت نفسك، فخلق لك الكراهة عند الشبع لتترك الأكل بها، وكذلك القول في شهوة الوقاع لحكمة بقاء النسل.

وكان خيثمى رحمه الله يصنع الخبيص والطعام الطيب، فيدعو إبراهيم والأعمش ويقول: كلوا، فما صنعته إلا لكم.

744 عن ابن عباس رضي الله عنهما عن النبي صلى الله عليه وسلم قال البركة تنزل وسط الطعام فكلوا من حافتيه ولا تأكلوا من وسطه رواه أبو داود والترمذي وقال حديث حسن صحيح

ومن ضرورة هذه النية أن لا يمد يده إلى الطعام إلا وهو جائع، وأن يرفع يده قبل الشبع، ومع فعل ذلك لم يكد يحتاج إلى طبيب، ومن ذلك أن يرضى بالموجود من الرزق، ولا يحتقر اليسير منه، وأن يجتهد فى تكثير الأيدى على الطعام ولو من أهله وولده.

Food selection associated with sense of coherence in adults.: Background: Favorable dietary habits promote health, whereas unfavorable habits link to various chronic diseases. An individual's "sense of coherence" (SOC) is reported to correlate with prevalence of some diseases to which dietary habits are linked. However, understanding what determines an individual's dietary preferences and how to change his/her behavior remains limited. The aim of the present study was to evaluate associations between dietary intake and SOC in adults. Methods: Diet intake w

Malnutrition in older adults: Correlations with social, diet-related, and neuropsychological factors.: Background: The number of older adults is increasing rapidly. Malnutrition is a major problem in this age group, which may adversely affect health and quality of life. Several physiological, socioeconomic, and neuropsychological factors can lead to malnutrition. Objectives: The aim of this study was to evaluate the nutritional status of community-dwelling older adults, and explore the associations of malnutrition risk with physiological, socioeconomic, and neuropsychological characteristics. Met

Effectiveness of Interventions and Behaviour Change Techniques for Improving Dietary Intake in Young Adults: A Systematic Review and Meta-Analysis of RCTs.: Poor eating habits are common during young adulthood and influence chronic disease morbidity. This systematic review evaluates the effectiveness of interventions aiming to improve dietary intake among young adults and, identifies which behaviour change techniques (BCTs) are most effective. Six electronic databases were searched for RCTs published until October 2018, and evaluating behavioural interventions assessing change in dietary intake in young adults (17-35 years). Of the 18,779 articles i

Associations between nutrition and the incidence of depression in middle-aged and older adults: A systematic review and meta-analysis of prospective observational population-based studies.: Aim: To systematically examine the longitudinal observational evidence between diet and the incidence of depression in adults aged 45 years and older. Method: Three electronic databases were searched for cohort studies published up to December 2020 that investigated the association between baseline dietary intake and incidence of depression in community-dwelling adults aged 45+years. Combined odds ratios (OR) and 95% confidence intervals (95%CI) were calculated. Random-effects models were used.

Dietary patterns and stroke: a systematic review and re-meta-analysis.: The effect of diet on the development of stroke has recently achieved much interest by various research groups, but with inconclusive results. The aim of the present review was to systematically present and discuss the up to date available research regarding the relationship between adherence to dietary patterns and stroke. Studies included were observational and randomized clinical trials. Internet searches until May 31, 2014, retrieved 152 potentially relevant papers; of them, 34 were excluded

Effects of Polyphenols in a Mediterranean Diet on Symptoms of Depression: A Systematic Literature Review.: Depression is a mood disorder which currently affects 350 million individuals worldwide. Recently, research has suggested a protective role of diet for depression. The Mediterranean-style dietary pattern has been highlighted in several systematic reviews as a promising candidate for reducing depressive symptoms. It has been speculated that this could be due to the high polyphenol content of foods commonly found in the diet. Therefore, the aim of this review was to assess the effects of polypheno

The Muslim football player and Ramadan: current challenges.

Islam is a monotheistic Abrahamic faith characterised by devotional orthopraxy. The actions expected of followers of Islam are closely prescribed in the Qur'an. Muslims understand Ramadan as a mandatory requirement, excused only in the event of illness, infirmity or extremes of age. Due to the increasing popularity of football among Muslims, more and more Muslim football players of all levels make the decision to follow the Ramadan fast while they need to practise and compete. Sports medicine clinicians and scientists have the responsibility to provide them with the knowledge and evidence on how exactly Ramadan fasting impacts on their performance and how to optimise their eating, drinking and sleeping in order to minimise negative effects of their religious practice, should any have been demonstrated. The first International Federation of Football Associations (FIFA) Medical Assessment …

Predictors of measurement error in energy intake during pregnancy.

Nutrition plays a critical role in maternal and fetal health; however, research on error in the measurement of energy intake during pregnancy is limited. The authors analyzed data on 998 women living in central North Carolina with singleton pregnancies during 2001-2005. Second-trimester diet was assessed by food frequency questionnaire. Estimated energy requirements were calculated using Institute of Medicine prediction equations, with adjustment for energy costs during the second trimester. Implausible values for daily energy intake were determined using confidence limits of agreement for energy intake/estimated energy requirements. Prevalences of low energy reporting (LER) and high energy reporting (HER) were 32.8% and 12.9%, respectively. In a multivariable analysis, pregravid body mass index was related to both LER and HER; LER was higher in both overweight (odds ratio = 1.96, 95% co…

Dietary intake of n-3 and n-6 fatty acids and the risk of clinical depression in women: a 10-y prospective follow-up study.

Background: The associations between different sources of dietary n-3 (omega-3) and n-6 (omega-6) fatty acids and the risk of depression have not been prospectively studied. Objective: The objective was to examine the relation between different n-3 and n-6 types with clinical depression incidence. Design: We prospectively studied 54,632 US women from the Nurses' Health Study who were 50-77 y of age and free from depressive symptoms at baseline. Information on diet was obtained from validated food-frequency questionnaires. Clinical depression was defined as reporting both physician-diagnosed depression and regular antidepressant medication use. Results: During 10 y of follow-up (1996-2006), 2823 incident cases of depression were documented. Intake of long-chain n-3 fatty acids from fish was not associated with depression risk [relative risk (RR) for 0.3-g/d increment: 0.99; 95% CI: 0.88, …

Mulberry fruit protects dopaminergic neurons in toxin-induced Parkinson's disease models.

Parkinson's disease (PD), one of the most common neurodegenerative disorders, is characterised by the loss of dopaminergic neurons in the substantia nigra pars compacta (SNpc) to the striatum (ST), and involves oxidative stress. Mulberry fruit from Morus alba L. (Moraceae) is commonly eaten, and has long been used in traditional oriental medicine. It contains well-known antioxidant agents such as anthocyanins. The present study examined the protective effects of 70 % ethanol extract of mulberry fruit (ME) against neurotoxicity in in vitro and in vivo PD models. In SH-SY5Y cells stressed with 6-hydroxydopamine (6-OHDA), ME significantly protected the cells from neurotoxicity in a dose-dependent manner. Other assays demonstrated that the protective effect of ME was mediated by its antioxidant and anti-apoptotic effects, regulating reactive oxygen species and NO generation, Bcl-2 and Bax pr…

Poor maternal nutrition followed by accelerated postnatal growth leads to telomere shortening and increased markers of cell senescence in rat islets.

Low birth weight (LBW) followed by accelerated postnatal growth is associated with increased risk of developing age-associated diseases such as type 2 diabetes. Gestational protein restriction in rats causes LBW, beta-cell dysfunction, and reduced longevity. These effects may be mediated by accelerated cellular aging. This study tested the hypothesis that LBW followed by rapid postnatal catch-up growth leads to islet telomere shortening through alterations in antioxidant defense capacity, stress/senescence marker proteins, and DNA repair mechanisms at the gene expression level. We used our rat model of gestational protein restriction (recuperated offspring) and control offspring. Southern blotting revealed shorter (P<0.001) islet telomeres in recuperated animals compared to controls. This was associated with increased expression of peroxiredoxin 1 (P<0.05), peroxiredoxin 3 (P<0.01), and …

Intergenerational transmission of glucose intolerance and obesity by in utero undernutrition in mice.

Objective: Low birth weight (LBW) is associated with increased risk of obesity, diabetes, and cardiovascular disease during adult life. Moreover, this programmed disease risk can progress to subsequent generations. We previously described a mouse model of LBW, produced by maternal caloric undernutrition (UN) during late gestation. LBW offspring (F(1)-UN generation) develop progressive obesity and impaired glucose tolerance (IGT) with aging. We aimed to determine whether such metabolic phenotypes can be transmitted to subsequent generations in an experimental model, even in the absence of altered nutrition during the second pregnancy. Research design and methods: We intercrossed female and male F(1) adult control (C) and UN mice and characterized metabolic phenotypes in F(2) offspring. Results: We demonstrate that 1) reduced birth weight progresses to F(2) offspring through the paternal l…

Biological Activities Underlying the Cardiovascular Benefits of Olive Oil Polyphenols: Focus on Antioxidant, Anti-Inflammatory, and Anti-Atherogenic Effects.

Extra virgin olive oil (EVOO) polyphenols are recognized for their beneficial effects on human health, yet how their concentration shapes biological outcomes remains insufficiently explored. While a daily intake of 25 mL EVOO is generally regarded as beneficial for cardiovascular protection, the high-phenolic EVOO examined in this study contains markedly higher levels of polyphenols than most EVOOs reported previously. This suggests that oils richer in polyphenols may exert distinct biological effects. To investigate this, we compared extracts from a standard EVOO and a naturally high-phenolic EVOO, along with their key phenolic compounds, hydroxytyrosol (HT) and tyrosol (Tyr). Antioxidant effects were assessed by quantifying intracellular reactive oxygen species (ROS) and lipid peroxidation. Anti-inflammatory activity was evaluated in THP-1-derived macrophages stimulated with LPS by ana…

Multi-objective Optimization of Molecular Distillation Conditions for Oleic Acid from a Rich-in-Fatty Acid Model Mixture.

Oleic acid is a commercially valuable compound and has many positive health effects. Determining optimum conditions in a physical separation process is an industrially significant point due to environmental and health related concerns. Molecular distillation avoids the use of chemicals and adverse effects of high temperature application. The objective of this study was to determine the molecular distillation conditions for oleic acid to increase its purity and distillation yield in a model fatty acid mixture. For this purpose, a short-path evaporator column was used. Evaporation temperature ranged from 110 to 190℃, while absolute pressure was from 0.05 to 5 mmHg. Results showed that elevating temperature generally increased distillation yield until a maximum evaporation temperature. Vacuum application also affected the yield at a given temperature, and amount of distillate increased at h…
