In a year when plant-based eating keeps rising for health, ethics and the planet, Oscar-winner Joaquin Phoenix and Grammy star Billie Eilish, both long-time vegans, continue to highlight the power of compassionate choices.
Yet dietitians warn that many vegetarians still fall into the same traps that drain energy and long-term wellness. Recent reviews and expert guides from 2025-2026 show the same pattern: good intentions, incomplete planning.
Skipping the one nutrient plants cannot supply
Vitamin B12 remains the top concern. It appears almost only in animal foods or fortified products. Without a daily or weekly supplement, fatigue, nerve issues and higher inflammation risk can creep in.
Experts stress that even lacto-ovo vegetarians often need extra B12 because dairy and eggs may not cover needs fully.
Underestimating iron and omega-3s
Plant iron (non-heme) is harder for the body to absorb than the form in meat. Pairing lentils, spinach or fortified cereals with vitamin C-rich foods helps but many still develop low stores.
Omega-3 fats, especially the brain and heart friendly EPA and DHA are also scarce without algae oil or careful use of flax, chia and walnuts. New studies link balanced intakes to better mood and cardiovascular markers.
Relying on the same few foods or processed swaps
Eating only fruit, salad and the same two proteins leaves gaps in zinc, calcium, iodine and complete amino acids. Ultra-processed vegan burgers, cheeses and snacks often load sodium and empty calories while cutting fiber. Variety – beans, tofu, tempeh, nuts, seeds, whole grains and fortified plant milks – fixes this fast.
Not eating enough overall
Plant foods are filling but lower in calories. Many new vegetarians feel tired simply because portions stayed the same after dropping meat and dairy. Adding healthy fats and larger servings of legumes restores energy.
The Academy of Nutrition and Dietetics still confirms that well-planned vegetarian diets are nutritionally adequate and linked to lower chronic-disease risk. The difference is intention: track the key nutrients, use supplements where needed and keep the plate colorful.
Phoenix and Eilish’s message stays clear – compassion works best when the body thrives too.
