The Health and Food Supplements Information Service (HSIS) has highlighted the need for supplementation when cutting down on animal foods. Its report, based on data from over 17,000 people, found that those on plant-based diets, vegans and vegetarians are risking dietary shortfalls for optimal wellbeing and health as well as undermining their micronutrient status. Many were found to be deficient in vitamin B12, vitamin D, iron, zinc, iodine, selenium and omega-3 fats.
Several of these nutrients – iron, zinc and selenium – are known to support normal immune function, essential for our health and wellbeing and are particularly relevant at this time. Low levels of iron and B vitamins can also lead to tiredness and fatigue, while iodine and iron are important for supporting cognitive function. Vitamin D is key for bone health, and omega-3 fats are vital for protecting heart and brain.
