The document discusses the relationship between nutrition and mental health. It suggests that many psychiatric illnesses may be treated as nutritional deficiencies rather than with drugs. It provides examples of vitamins and minerals like vitamin B3, C, D, and E that can help treat conditions like depression when provided at optimal levels. The document questions the widespread use of antidepressants and suggests nutrition and lifestyle changes may help address the root causes of mental illness.
In this informative webinar, with expert nutritionist Dr Nina Bailey, you will learn about how we can optimise our diet to help manage depressive symptoms:
- Foods the brain needs to function: what we should be eating
- Foods that starve the brain of nutrients: what foods we really need to avoid
- Food, mood and money: how to eat well on a budget
- Supplements: the best nutrients for depression, backed up by science
By making some relatively simple dietary changes that may, in some cases, include the use of dietary supplements, it is possible to see significant improvement in symptoms.
The document discusses the topic of designer babies through several arguments. It addresses the ethical issues with creating babies for the purpose of being organ donors. It also discusses the arguments that designer babies could increase social inequality and that parents may be disappointed if a designer baby does not meet their expectations. Another argument is that designer babies could help populations live longer and resist diseases, potentially leading to overpopulation. The document concludes that designer babies are not a good idea due to these various ethical concerns.

The document compares junk food and healthy food. It describes junk food as having little nutritional value and containing empty calories or unhealthy ingredients. Healthy food is described as food that provides nutritional benefits beyond a normal diet. The document then analyzes the nutritional content of a McDonald's meal containing a double cheeseburger, large fries, soda, and McFlurry and finds it exceeds recommended daily guidelines for calories, fat, sugars and other nutrients. Long term effects of a junk food diet are said to include lack of energy, poor concentration, heart disease, and high cholesterol. The document concludes by providing 10 keys to a healthy diet.
The document discusses the relationship between autism and nutrition from three perspectives: how nutrition may impact autism development, how food issues can manifest as autism symptoms, and how diet can be used as an autism treatment. It explores various dietary approaches used for autism including gluten-free, probiotic, vitamin/mineral supplementation, and metabolic therapies. While research on nutrition and autism is still emerging, dietary changes may help alleviate gastrointestinal and behavioral problems for some people with autism.
Food and mood - dietitian presentation for depressionDawn Shotton
This document discusses the relationship between food and mood. It notes that diet is an important factor in both the prevention and management of low mood. Specific foods that can help include oily fish, olive oil, nuts and seeds to increase omega-3 intake; protein sources like meat, fish, eggs, dairy and legumes; and vitamin B-rich foods like vegetables, fruit, wholegrains and fish. Maintaining healthy blood sugar levels by eating high-fiber starchy foods and staying hydrated can also benefit mood. Regular exercise is additionally recommended.
A intoxicação alimentar é uma doença causada pela ingestão de alimentos contaminados com bactérias, parasitas ou vírus, podendo causar náusea, vômitos, diarreia e dor abdominal. Pessoas idosas, grávidas, crianças e portadores de doenças crônicas correm maior risco. Frutas e vegetais lavados com água contaminada também podem transmitir bactérias.
The document discusses nutrients that are important for managing depression, including smart carbs that have a calming effect, protein-rich foods that boost alertness, getting enough vitamin D, selecting selenium-rich foods, including omega-3 fatty acids, eating an antioxidant rich diet, maintaining a healthy weight and lifestyle, avoiding alcohol and smoking, and how healthy eating along with other therapy can help get rid of depression.
This document discusses designer babies. It defines a designer baby as one whose genetic makeup has been artificially selected through genetic engineering to ensure particular genes or characteristics. The first designer baby, Adam Nash, was born in 2000 using pre-implantation genetic diagnosis to screen embryos for genetic disorders prior to implantation. While designer babies allow for healthy children and gender selection, there are also moral, ethical, social, and safety concerns. Currently, fertility clinics in major US cities conduct research on prenatal genetic testing to eliminate diseases.
Snacking appears to be hard, time consuming and some even think it's a bad thing.
But it's worth it!
Without sustainable fuel sources throughout the day, you will crave quick fixes from empty calories such as chips, chocolate, biscuits as well as coffee, "energy" drinks and soft drinks.
By not snacking or choosing empty calories, the body reacts as if it's starving and conserves any stored calories for later.
This means the rate at which you burn calories slows down, your body stores every calorie you consume as fat whether it's good or bad calories, especially around the tummy area.
The document discusses the negative health impacts of junk food consumption. It notes that while occasional junk food won't significantly hurt health, regular consumption can increase risks of obesity, cardiovascular disease, diabetes, and some cancers. Data shown indicates that a large percentage of children consume packaged and processed foods like chips, cereals, and sweet snacks on a regular basis. The risks of excessive junk food are then outlined, and practical ways to reduce consumption are suggested, such as eating more fruits, eggs, oats, nuts and dark chocolate, planning meals, and learning to decline junk food options.
The document discusses how brain structure and function can change with depression and bipolar disorder. It describes how the hippocampus shrinks with these conditions, increasing risks for memory problems and dementia. Exercise and meditation are highlighted as ways to potentially reverse hippocampal shrinkage and improve brain plasticity and cognitive function. Drug therapies are noted to have risks of worsening symptoms or converting unipolar depression to bipolar disorder.
This document discusses the relationship between depression and diet. It begins by defining depression and listing common symptoms. It then explains that when people are depressed, they often eat unhealthy foods high in saturated fat, sugar, and caffeine to cope, which can worsen their mood. The document recommends avoiding caffeine, sugar, alcohol, and drugs, and instead eating lean proteins, whole grains, fruits and vegetables to stabilize blood sugar. Omega-3 fatty acids, vitamin D, and selenium from foods like fish, nuts, and leafy greens may also help manage depression symptoms. In conclusion, maintaining a balanced diet can elevate mood and energy when feeling depressed.
Genetically modified organisms (GMOs) are organisms whose genetic material has been altered using genetic engineering techniques. This technology is used to address issues like food shortages caused by overpopulation. GMOs are designed to increase crop yields and make plants resistant to pests and environmental stressors in order to boost food security. Examples of genetically modified crops include pesticide-resistant rape plants, golden rice enriched with vitamin A, and long-lasting tomatoes that have increased shelf life. While GMOs aim to benefit farmers and consumers, their safety and environmental impacts remain debated topics.
Eight laws of restoring health presentationStephen Ayere
This document introduces the laws of restoring health according to nutritionist Stephen Ayere. The eight laws are: Nutrition, Exercise, Water, Sunshine, Temperance, Air, Rest, and Trust (NEW START). Each law is briefly explained. Nutrition involves eating grains, seeds, fruits, vegetables, nuts and herbs. Exercise provides benefits like improved cardiovascular health. Water intake should be based on body weight. Sunlight produces vitamin D and benefits health. Temperance means moderation. Fresh air purifies the blood. Rest allows the body to repair and reset. Trusting in God can reduce stress levels.

FALSE. Skipping meals can actually slow down your metabolism and cause your body to store more fat. It's better to eat smaller, more frequent meals throughout the day.
This document provides information about food groups and nutrients needed for a balanced diet. It discusses vegetables, fruits, grains, dairy, and protein foods. It emphasizes the importance of whole grains, water, and calcium-rich foods for children. Carbohydrates, proteins, fats, and vitamins/minerals are described as essential nutrients. The document warns about the harmful effects of junk food, including fatigue, poor concentration, heart disease, and gastrointestinal issues. It recommends getting enough sleep, eating breakfast, eating mindfully, and doing exercises like leg raises, pushups, and crunches to maintain a healthy lifestyle.
This document discusses nutrition and dietetics programs which teach students how to use food therapeutically for disease management. Students learn food production techniques like menu planning, purchasing, storage, preparation, and cost control. Dietitians work in healthcare, education, corporate wellness, and research, using nutrition science to help people make healthy dietary choices and lifestyle improvements. Nutritionists study nutrients, diet, health, and may work in food science or journalism. Taking these courses prepares students to be clinical dietitians, community dietitians, or management dietitians who provide medical nutrition therapy, public nutrition programs, or manage food service operations.
A nutrição é essencial em todas as fases da vida, desde a infância até a velhice. Uma alimentação balanceada e saudável é importante para o crescimento, desenvolvimento e manutenção da saúde ao longo dos anos. Christianne de Vasconcelos Affonso é uma nutricionista com mestrado, doutorado e especialização que estuda os benefícios da nutrição no ciclo de vida humano.
The document discusses good and bad health habits. It notes that good habits include exercising regularly, eating a healthy diet with vegetables and whole grains, and sleeping 7-8 hours per night. Bad habits include smoking, drinking alcohol, taking drugs, physical inactivity, irregular eating patterns, and sleeping more or less than 7-8 hours. Maintaining good habits like a regular sleep schedule, exercise, and diet can promote better health outcomes, while bad habits are linked to diseases and early death.

La matière organique, seule ressource 100% renouvelableRéseau Tepos
QUELS GISEMENTS DE BIOMASSE ET COMMENT LES MOBILISER ?
Les gisements de biomasse sont nombreux et variés et offrent des perspectives intéressantes comme ressources pour des projets énergétiques. Que représentent ces gisements pour un territoire rural, en termes de volume et de potentiel d’énergie? Si la quantification de ces gisements n’est pas la partie la plus délicate, la connaissance des possibilités de mobilisation reste un exercice difficile et ouvre de nombreuses questions, en termes de compétitions d’usages et de gestion des ressources naturelles. Quelle concurrence existe-t-il effectivement sur les différents gisements présents sur un territoire : bois, ressources et déchets agricoles, déchets organiques ? Quels outils peuvent être mis en place pour une utilisation durable et efficace de la ressource ?
Animé par Adeline Haumont, chambre d’agriculture des Côtes d’Armor
Intervenants :
> La matière organique, seule ressource 100% renouvelable
Konrad Schreiber, association APAD/BASE (Bretagne Agriculture Sol Environnement)
> Nature et mobilisation des gisements bois énergie au niveau d'un territoire

Dans un contexte où la transmission et l'installation d'agriculteurs sont des enjeux cruciaux pour la profession agricole, de nouveaux agriculteurs s'installent chaque année et, parmi eux, certains Bac+5 ou plus. Les cursus des écoles d'ingénieurs n'ont pas vocation à former de futurs agriculteurs. Pourtant, certains apprenants ayant suivi ces cursus BAC + 5, qu'ils soient ou non issus du milieu agricole, tentent l'aventure de l'entrepreneuriat agricole. Qui sont-ils ? Quelles sont leurs motivations et visions ? Comment travaillent-ils ?
Organisé par le CIIRPO, ce webinaire fait le point sur les différents types de boiteries chez les brebis et les béliers illustrées de photos. Les modes de prévention et les traitements possibles sont cités.
L’équipe du projet BeBoP a proposé un webinaire le 30 mai 2024 pour découvrir comment la technologie vidéo, combinée à l’intelligence artificielle, se met au service de l’analyse du comportement des taurillons.

Effet de l’intégration de prairies temporaires
sur la microbiologie du sol
Dispositif expérimental de Lusignan
• Sols : limon-sableux
• 4 parcelles par modalité
Fonctionnement biologique du sol de la prairie permanente = ‘point de repère’
en terme de fertilité des sols.
Les prairies temporaires favorisent le fonctionnement biologique du sol.

• Les recherches bibliographiques et les expérimentations
réalisées montrent que l’intégration de prairies temporaires
et les apports d’effluents d’élevage ont un effet favorable sur
le fonctionnement microbiologique des sols : abondance et
activités enzymatiques.

Pour conclure
• Ces deux types de pratiques agricoles constituent, pour
l’élevage bovin lait, des leviers majeurs pour le maintien des
teneurs en carbone organique et de la fertilité des sols.
