Understanding what our bodies need isn’t always easy. Between daily cravings and seasonal changes, it can be hard to figure out what’s missing—and how to eat smarter. Let’s break it down.
🧬 Essential nutrients and their functions
Our body needs a mix of macronutrients and micronutrients to function well.
Macronutrients:
- Proteins – Build and repair tissues (meat, legumes, dairy)
- Carbohydrates – Main source of energy (whole grains, fruits, vegetables)
- Fats – Support brain, hormone balance, and energy (nuts, seeds, oils)
Micronutrients:
- Vitamins – Support immune system, skin, bones, metabolism (fruits, vegetables, dairy)
- Minerals – Help oxygen transport, muscle function, and hydration (leafy greens, nuts, fish)
- Fiber – Regulates digestion and stabilizes blood sugar (vegetables, legumes, oats)
- Water – Vital for every function in the body
🍽️ How much do we need and where to get it?
Here’s a quick guide to the most important nutrients, their recommended daily intake, and where to find them:
| Nutrient | Recommended daily intake* | Best sources |
|---|---|---|
| Protein | 50g (women), 60g (men) | Eggs, dairy, legumes, lean meat, tofu |
| Fiber | 25–30g | Whole grains, beans, fruits, vegetables |

🍫 What do cravings actually mean?
Sometimes your body tells you what it’s missing—if you know how to listen.
| Craving | Possible deficiency | Healthy sources |
|---|---|---|
| Chocolate | Magnesium | Nuts, seeds, leafy greens, legumes |
| Chips or salty foods | Mineral imbalance (sodium, potassium) | Avocado, nuts, bananas, sea salt |
| Ice cream or dairy | Calcium or fat | Full-fat yogurt, leafy greens, sesame |
| Sweet baked goods | Blood sugar imbalance or low chromium | Whole grains, sweet potato, apple with nut butter |
🥗 Can we get everything from food?
A balanced diet can often give you all the nutrients you need—no supplements required. Here’s how:
- Eat the rainbow (varied colors = varied nutrients)
- Include seasonal fruits and vegetables
- Mix plant-based and animal protein sources
However, supplements can help in certain cases:
- Vitamin D in winter
- Vitamin B12 for vegans
- Iron for menstruating women
Always check with your doctor before starting supplements.
🌦️ Nutrition and seasons: what changes?
Your nutritional needs shift with the seasons. Here’s what to add and why:
- Spring → Leafy greens, radishes, citrus (for cleansing and digestion)
- Summer → Cucumbers, melons, berries (hydration and antioxidants)
- Autumn → Onions, garlic, root vegetables (for immunity)
- Winter → Grains, legumes, fermented foods (for warmth and gut health)
💡 Tip: Start eating seasonally a few weeks before the season changes to support your body’s transition.
