Anses Study Reveals the Health Benefits and Risks of Plant-Based Diets
Vegetarian and vegan diets are on the rise globally, with millions embracing plant-based eating for health, ethical, and environmental reasons. But are these diets always safe for your body?
A groundbreaking five-year study by France’s Agency for Food, Environmental and Occupational Health & Safety (Anses) sheds light on both the benefits and potential risks of cutting out animal products.
✅ Health Benefits of Vegetarian & Vegan Diets
According to Anses, plant-based diets — when carefully balanced — can be very beneficial:
- Lower risk of type 2 diabetes – Vegetarians show a reduced risk compared to meat-eaters.
- Heart health support – Some evidence links plant-based diets with lower cholesterol, reduced inflammation, and improved cardiovascular function.
- Other possible perks – Better reproductive health, reduced risk of certain cancers, and even protection against some eye diseases.
👉 Takeaway: With good planning, vegetarian diets can protect long-term health.
⚠️ Health Risks of Poorly Planned Plant-Based Diets
The Anses report also warns of potential dangers if nutritional needs are not met:
- Bone health concerns – Higher risk of fractures due to calcium, vitamin D, and vitamin B12 deficiencies.
- Nutritional deficiencies – Low levels of iron, iodine, vitamin D, calcium, and vitamin B12 in vegetarians; vegans especially risk vitamin B2, B12, zinc, and Omega-3 fatty acid deficiencies.
- Possible risks in pregnancy – Early studies suggest concerns for fetal development if nutrient intake is inadequate.
👉 Takeaway: Supplements and fortified foods may be necessary for vegans and some vegetarians.
📊 What the Anses Study Found
Over five years of research and 131 studies, experts created detailed dietary guidelines:
- Balanced intake of legumes, grains, fruits, vegetables, nuts, and fortified foods is essential.
- Supplementation may be required for B12, vitamin D, calcium, zinc, and Omega-3.
- Nutritional risks are higher in vegans compared to vegetarians.
Perrine Nadaud, deputy head of Anses’ nutrition risk unit, noted that some evidence is weaker, but future research will refine these findings.
🥦 Key Nutritional Advice for Vegetarians & Vegans
To stay healthy, Anses recommends:
- Daily foods: legumes, whole grains, vegetables, fruits, nuts, seeds, brewer’s yeast, and dairy or fortified plant alternatives.
- Supplements if needed: Vitamin B12, Vitamin D, and Omega-3 are especially important.
- Careful balance: Ensure sufficient protein, calcium, iron, iodine, and zinc.
The UK’s NHS agrees: with careful planning, plant-based diets can be 100% healthy, but skipping nutrients increases risks.
🌍 Plant-Based Eating in France
- Only 2.2% of French adults are fully vegetarian (IFOP survey, 2021).
- Around 8% actively reduce meat consumption, citing animal welfare, environment, and health.
- A 2023 Nature study showed reducing meat consumption dramatically lowers greenhouse gas emissions, land and water use, and biodiversity loss.
📝 Final Word
The Anses study confirms that vegetarian and vegan diets can be healthy — but only with careful planning. While benefits include reduced diabetes and heart risks, the downsides include possible bone weakness and nutritional deficiencies.
👉 Anyone considering plant-based eating should consult a healthcare or nutrition professional to build a safe, balanced diet.
