The body needs fats, but there is no biological need specifically for animal fat.
When a doctor advises consuming it, it is worth clarifying: what specific problem are they trying to solve—lack of calories, protein, omega-3s, vitamins, low body weight, or test results.
What the body actually needs
Fats are an important part of nutrition. They provide energy, help absorb vitamins A, D, E, and K, and play a role in the functioning of the nervous system and hormonal balance. However, what is essential is not “animal fats” as such, but certain fatty acids—above all omega-3 and omega-6.
These can be obtained from plant foods: ground flaxseed, chia seeds, walnuts, hemp seeds, soy products, canola oil, and olive oil. If a person does not eat fish, and especially if they follow a vegan diet, it is helpful to discuss DHA/EPA omega-3 from algae with a doctor or dietitian. This is a more reliable source of these forms of omega-3 than relying only on the body’s conversion of plant alpha-linolenic acid.
So, the phrase “you need animal fats” is sometimes an oversimplification. It would be more accurate to say: “you need enough quality fats and adequate nutrition.” For some people, animal products may be a convenient source of nutrients; for others, a well-planned plant-based diet can meet these needs without them.
Why doctors may insist specifically on animal foods
Doctors often see not well-planned vegetarianism, but a very limited diet: cereals, potatoes, bread, and a little vegetables and fruit. Such a menu really may lack energy, protein, zinc, iodine, iron, calcium, vitamin D, vitamin B12, and fats in general. If a person is losing weight, constantly tired, has anemia, or has low lab values, a doctor may recommend eggs, dairy products, fish, or meat as a simple and familiar way to make the diet more nourishing.
Such advice should not be rejected automatically. It is wise to ask clarifying questions: “Which exact indicator is low for me?”, “Do I have a deficiency?”, “What tests confirm this?”, “Can the problem be corrected with plant foods or supplements?” In this way, the conversation moves from a general statement to a personal, well-grounded recommendation.
At the same time, it is not wise to prescribe yourself large amounts of oil, nuts, or supplements simply because “fat is needed.” Excess calories, fried foods, butter, fatty cheeses, and trans fats do not become a healthy solution. What matters is the overall way of eating, the condition of the heart and blood vessels, blood lipid levels, body weight, activity, and individual diseases.
Practical guidance for vegetarians and vegans
If you are a vegetarian and consume eggs and dairy products, you are already getting some animal fat, protein, and vitamin B12. Plain yogurt, kefir, eggs, or a moderate amount of cheese can be part of the diet if they are well tolerated and do not conflict with your medical needs. But this does not mean that butter, cream, or fatty cheeses should become the foundation of your diet.
If you are vegan, planning is especially important. Include legumes daily: beans, lentils, chickpeas, peas, soy, tofu, or tempeh. Add nuts, seeds, tahini, or a small amount of unrefined vegetable oils. Regularly consume flax or chia; flax is better ground so that the nutrients are absorbed more fully. For a vegan, vitamin B12 is not optional but a necessary supplement that should be taken in a reliable form and dose as advised by a specialist.
It is helpful to monitor lab tests periodically, especially B12, ferritin, a complete blood count, vitamin D, and, according to individual indications, other parameters as well. This is not a sign of distrust in plant-based eating, but responsible care for the body.
The biblical principle of health and freedom
The Bible does not suggest turning food into a measure of spirituality. It calls for gratitude, moderation, and a responsible attitude toward one’s own body. The apostle Paul reminds us that not everything that is formally permitted is truly beneficial.
“All things are lawful for me, but not all things are helpful; all things are lawful for me, but I will not be brought under the power of any.” 1 Cor 6:12
This principle helps avoid extremes: not despising medical advice, but also not accepting general statements without understanding your own condition. Food should serve life, health, and the ability to serve God and people.
“Therefore, whether you eat or drink, or whatever you do, do all to the glory of God!” 1 Cor 10:31
Ellen G. White did not call for thoughtless uniformity. In her health counsels, she emphasized simplicity, moderation, adequate nourishing food, and consideration of a person’s real needs. Her approach supports neither indulgence nor food fanaticism.
Conclusion and next step
Animal fat is not an essential nutrient. But a particular person may need additional calories, protein, B12, omega-3, or correction of an identified deficiency. Therefore, do not argue with your doctor only at the level of principle. At your next appointment, ask for the specific medical reason for the recommendation and the list of tests. Then, together with a competent specialist, build a realistic diet: enough protein, healthy fats, B12, and a variety of whole plant foods. This will be a wise, peaceful, and responsible application of the biblical principle of caring for health.
