التصميم البشري والتغذية: نظام PHS للأكل الصحيح

What Is PHS?

PHS (Primary Health System) is the nutrition system in Human Design that determines how your body needs to receive food. It's not a diet in the traditional sense — it's the mechanics of how your organism best absorbs nutrients.

PHS is based on the design side of your bodygraph — the part determined prenatally and connected to the unconscious functioning of the body.

Colors, Tones, and Bases

In Human Design, each planetary activation has three levels of detail:

• Color: 1-6 — determines your dietary type (Determination)
• Tone: 1-6 — refines the eating method
• Base: 1-5 — the deepest level of fine-tuning

For PHS, we look at the Color of the Design Sun/Earth (red calculation line). This determines your Determination — your dietary type.

The 6 Dietary Types (Determination)

1. Consecutive

Your body best absorbs food when you eat one item at a time.

• Don't mix many ingredients in one dish
• Eat simple meals with minimal components
• A 10-ingredient salad isn't for you. Better to eat vegetables separately, then meat
• Ideal: mono-eating. Rice separate, chicken separate, vegetables separate

2. Alternating

The opposite of Consecutive. Your body needs variety and mixing.

• Complex dishes with many ingredients are your path
• Stews, curries, complex salads, bowl meals
• Alternate food types throughout the day
• Mono-diets absolutely don't work for you

3. Open

Your body needs an open, calm environment for eating.

• Eat in open spaces, by windows, on terraces
• Avoid tight, stuffy rooms
• Fresh air during meals improves absorption
• Don't eat in basements, cramped kitchens, or closed rooms

4. Closed

The opposite of Open. Your body needs a cozy, enclosed space.

• Eat at home, in comfortable restaurants, in familiar places
• Dim lighting, calm atmosphere
• Avoid eating on the go, outdoors, or in noisy food courts
• Your kitchen is your sanctuary for meals

5. Hot

Your body best absorbs hot food and beverages.

• Soups, hot dishes, warm drinks
• Cooked food is better than raw
• Even water is better warm
• Minimize raw food like sushi and salads

6. Cold

The opposite of Hot. Your body needs cold and raw food.

• Salads, fruits, smoothies, cold appetizers
• Raw food is better absorbed
• Cold water, cool drinks
• Avoid overly hot dishes

Tones: Refining Your Type

Each of the 6 types has 6 tones that refine the eating method:

• Tone 1 (Smell): eat what smells good to you
• Tone 2 (Taste): trust your taste preferences
• Tone 3 (Outer Vision): eat what looks appetizing
• Tone 4 (Inner Vision): visualize food before choosing
• Tone 5 (Feeling): feel what the body wants
• Tone 6 (Touch): food texture matters

3. Go to the Variable tab — you'll see your dietary type
4. Look at the Design Sun — the Color determines your Determination

Practical Tips

Experiment with PHS gradually:

• Don't change everything at once. Start with one meal per day
• Observe post-meal sensations: energy, lightness, bloating, fatigue
• PHS is not about WHAT to eat, but HOW to eat. You can eat the same foods, but differently
• Give your body 3-6 months to adapt
• Keep a food and well-being journal

Important Note

PHS is an experiment, not a dogma. Ra Uru Hu always emphasized: verify everything through your own experience. If something doesn't work for your body — listen to the body, not the theory. PHS also doesn't replace medical recommendations for health conditions.
