Abstract
The causes of migraine appear to be multifactorial and can manifest in many different ways, so the importance of evaluating migraines from a Functional Medicine (FM) perspective to identify potential imbalances in the body is pivotal. Dr Mark Hyman speaks to Dr Todd LePine, an Institute for Functional Medicine Certificated Practitioner to discuss how to identify and eliminate migraines and the differences between the conventional and FM approach. They review the connection between migraines and gut health, nutrient deficiencies such as magnesium, histamine sensitivity, genetics, the role of mitochondria and also lifestyle factors such as sleep and stress which can exacerbate symptoms. Exploring dietary and sleeping patterns and stress exposure/management appears to be key for first line migraine prevention. However they also review functional testing that may be helpful to identify the root cause, and supplementing with Magnesium, CoQ10, and Vitamin B2.

Eating for Migraines with Dr Jessica Briscoe and Dr Katy Munro
Dr Rupy Aujla is an NHS medical doctor who reversed his heart condition using a food and lifestyle approach after diving deep into the literature and learning more about nutritional medicine. He started the Doctor’s Kitchen in 2015, as a way to teach others how they can cook their way to health and showcase that food is medicine.

Abstract
Rupy chats with Dr Jessica Briscoe and Dr Katy Munro from The National Migraine Centre, a national charity with a clinic providing evidence based support for migraine sufferers. A diverse conversation covering migraine diet myths, as well as diet and lifestyle factors that can both trigger and prevent migraines. From a dietary perspective, eating regularly and stabilising glucose levels appears to be a primary factor in preventing migraines, but the potential use of ketogenic diets for pain and migraine management is also explored. The evidence around caffeine, exercise, pre and probiotics, sleep, stress management and supplements like Magnesium, CoQ10, and Vitamin B2 are reviewed.

Plain language summary
This systematic review investigated vegan diets in the European populations and their adequacy of macro-and micronutrient intake, compared to the recommendations of the World Health Organization. Included were 48 studies and their outcomes regarding protein, carbohydrates, fats and micronutrients summarized. The overall results and their impact on health are discussed in the later sections of the paper. Adequate intake amongst vegans was seen with carbohydrates, fats, Vitamin A, B1, В6, C, E, iron, phosphorus, magnesium, copper and folate. Sodium exceeded recommended intake, whilst protein, Vitamin B2, B3, B12, D, iodine, zinc, calcium, potassium, selenium was of low consumption in a vegan diet. The bioavailability of some nutrients was also acknowledged. In summary, following a vegan diet appears to have positive and negative aspects. A vegan diet profile can contribute to disease prevention with lower incidence rates of obesity, Type 2 diabetes, and cardiovascular disease. Yet veganism appears to increase the risk for mental health conditions, bone fractures, immune system impairments, anaemias and deficiencies from low nutrient intake. This review yields a comprehensive overview of the positive and negative health consequences of a vegan diet. It may be a useful reference for those looking to support vegans or individuals considering adopting a vegan diet pattern.
Expert Review
Conflicts of interest:
None
Take Home Message:
- Vegan diets in European populations tend to be lower in protein intake, particularly amino acids lysine, methionine and tryptophan.
- Other micronutrients that tend to lower in vegan diets are Vitamin B12, zinc, calcium and selenium.
- Healthcare practitioners should be aware of these potential deficiencies when working with vegan clients.

Summary Review:
Vegan diets have become increasingly popular in the last ten years. This systematic review of 48 studies investigated the adequacy of vegan diets in European populations. It compared their macro- and micronutrient intakes compared to World Health Organization recommendations. It found that vegan diets tend to be lower in protein and in essential amino acids (lysine, methionine and tryptophan). They can also be lower in micronutrients especially vitamin B12, zinc, calcium and selenium. However, the lower intakes are not always associated with health impairments.
Clinical practice applications:
Practitioners should be aware of the potential deficiencies in a vegan diet.
Considerations for future research:
More research is needed to determine whether lower nutrient intakes in vegans correlated with poor health outcomes.
Abstract
BACKGROUND Vegan diets, where animal- and all their by-products are excluded from the diet, have gained popularity, especially in the last decade. However, the evaluation of this type of diet has not been well addressed in the scientific literature. This study aimed to investigate the adequacy of vegan diets in European populations and of their macro- and micronutrient intakes compared to World Health Organization recommendations. METHODS A systematic search in PubMed, Web of Science, IBSS, Cochrane library and Google Scholar was conducted and 48 studies (12 cohorts and 36 cross-sectional) were included. RESULTS Regarding macronutrients, vegan diets are lower in protein intake compared with all other diet types. Veganism is also associated with low intake of vitamins B2, Niacin (B3), B12, D, iodine, zinc, calcium, potassium, selenium. Vitamin B12 intake among vegans is significantly lower (0.24-0.49 μg, recommendations are 2.4 μg) and calcium intake in the majority of vegans was below recommendations (750 mg/d). No significant differences in fat intake were observed. Vegan diets are not related to deficiencies in vitamins A, B1, Β6, C, E, iron, phosphorus, magnesium, copper and folate and have a low glycemic load. CONCLUSIONS Following a vegan diet may result in deficiencies in micronutrients (vitamin B12, zinc, calcium and selenium) which should not be disregarded. However, low micro- and macronutrient intakes are not always associated with health impairments. Individuals who consume a vegan diet should be aware of the risk of potential dietary deficiencies.
