Starting solid foods is one of the most important milestones in a baby’s development journey. And one of the most common questions parents often ask is: What oil should I give my baby when starting to eat solid foods? Choosing the right weaning oil not only makes baby meals tastier but also acts as the “golden key” to help your little one absorb nutrients effectively, supporting optimal brain, physical, and immune development.
Not all oils are suitable for a baby’s delicate digestive system. From olive oil, walnut oil, sesame oil to gac oil, each type offers unique benefits. What truly matters is choosing oils that are gentle, easy to digest, and age-appropriate for baby
Why Are Healthy Fats Important in Baby Weaning?

Fats are more than just a rich source of energy—providing about 9 kcal/g, over twice as much as protein or carbohydrates. They also play a crucial role in your baby’s overall development:
-
Brain & Nervous System Development:Omega-3 fatty acids (DHA, ALA) in salmon oil or walnut oil are the building blocks of brain tissue, nerves, and the retina. A deficiency may impact cognition and vision later in life.
-
Absorption of Fat-Soluble Vitamins (A, D, E, K):These vitamins require fat to be absorbed—especially vitamin A from gac oil or carrot oil, which is vital for vision and immunity.
-
Protecting Internal Organs:Cell membranes in your baby’s body are largely made of lipids, making fats an essential structural component.
-
Growth & Immunity:Oils like black sesame oil contain trace minerals such as calcium and magnesium, which support bone growth and immune balance.
Choosing nutrient-rich oils ensures a strong nutritional foundation for your baby’s future.
When Should You Start Adding Oil to Baby Food?

Việc bắt đầu cho bé dùng dầu ăn nên được cân nhắc kỹ về độ tuổi và phản ứng tiêu hóa:
-
Around 6 months of age: Once your baby starts weaning and gets used to plain porridge, you can begin with ½ teaspoon of oil.
-
After the initial adjustment period:Introduce oil only after your baby has successfully digested solids without oil for a few days.
-
Increase gradually:If digestion is stable (no diarrhea, bloating, or vomiting), you can increase from ½ tsp → 1 tsp → 1 tsp per meal, not exceeding ~5 ml/day for babies under 1 year old.
If your baby struggles with poor appetite, slow weight gain, or vitamin deficiencies, oil can be helpful—just monitor carefully to avoid overloading the digestive system.
How to Choose Safe Cooking Oils for Babies
When it comes to choosing the right oil for your baby, focus on both nutrition and purity:
-
Cold-pressed / Extra Virgin Oils:Retain maximum nutrients (vitamins, DHA, antioxidants) since they are not exposed to high heat. Recommended options: extra virgin olive oil, cold-pressed gac oil.
-
No preservatives, bleaching agents, or artificial flavors:These additives can irritate your baby’s gut and weaken their immune system.
-
Organic oils:Certified organic oils ensure purity—free from pesticides and chemicals.
-
Clear labeling & traceability:Choose oils with transparent origin, production, and expiry details. Avoid oils that smell rancid, have turned cloudy, or changed color.
