The nutrients that are known to boost mood are Vitamins B & D, Iron, Zinc, Healthy fats, Omega-3s. These nutrients are essential for brain health and function, and deficiencies in these nutrients can lead to mood disorders like depression.

Here's a step-by-step explanation:

1. Vitamins B & D: These vitamins are crucial for brain health. Vitamin B helps the body produce serotonin, a neurotransmitter that regulates mood. Vitamin D deficiency has been linked to depression, and it's thought that increasing your intake can help improve your mood.

2. Iron: Iron is essential for producing dopamine, another neurotransmitter that plays a key role in mood regulation. Iron deficiency can lead to fatigue and depression.

3. Zinc: This mineral is crucial for brain function and a deficiency can lead to depression.

4. Healthy fats: Healthy fats, like those found in avocados and nuts, are essential for brain health. They help the brain function properly and can improve mood.

5. Omega-3s: These fatty acids are known to have a number of health benefits, including improving brain health and mood. They're found in fatty fish, like salmon and mackerel, as well as in flaxseeds and walnuts.

Sugars and carbohydrates can provide a temporary mood boost, but they can also lead to a crash later on. Saturated fats, caffeine, and artificial sweeteners are not typically associated with mood improvement. In fact, they can have negative effects on mood and overall health.
