Understanding Nutrient Balance Ratios
Proper nutrient balance is essential for various bodily functions, including metabolism, energy production, and overall health.
Similar-sized nutrients and minerals with similar charges (e.g., magnesium and calcium are both +2) compete for absorption in our bodies and often play synergic roles, so it’s important to keep them in balance so you can absorb and use enough of each to thrive.
Key nutrient ratios to monitor and their target ranges are:
- omega-6:omega-3 ratio: Crucial for reducing inflammation and promoting heart health — aim for a ratio of less than 4:1.
- calcium:magnesium ratio: Both minerals are vital for bone health, muscle function, and cardiovascular health — aim for between 1 and 3.
- potassium:sodium ratio: Balancing these electrolytes helps maintain blood pressure, fluid balance, and heart function — Aim for greater than 1 if you’re lean, active and sweat a lot or greater than 2 if you’re sedentary or have higher blood pressure.
- zinc:copper ratio: These trace minerals are essential for immune function, antioxidant defence, and neurological health — aim for between 8 and 12.
- iron:copper ratio: Both minerals are necessary for red blood cell production and iron metabolism — aim for between 10 and 15.
How to Achieve Optimal Nutrient Balance
The charts below show the nutrient balance ratio dials in Nutrient Optimiser, similar to those in Cronometer. Ideally, you want to see your ratios in the green zone.
So, what do these dials tell us about this person’s diet?
- omega 6:omega 3 ratio: They are getting enough omega 3 without excessive omega 6.
- zinc:copper ratio: They should prioritise foods that contain more zinc and/or reduce foods that contain copper.
- potassium:sodium: They need to prioritise potassium and reduce added salt.
- calcium:mangesium ratio: They need more magnesium to reduce the ratio of calcium to magnesium.
- iron:copper: They need more iron or less copper.
Manual and Automated Nutrient Balancing
To identify the foods you need to increase or reduce, in Cronometer, mouse over the nutrient bars in the daily diary to see a popup showing the foods that contain those nutrients.
In the scenario above, they should reduce high-copper foods. Higher intakes of liver and other organ meats are generally the culprit with higher copper intake.
To bring their potassium:sodium ratio into the green zone, they could prioritise potassium-rich foods and dial back their added salt.
However, we realised that doing this manually in Cronometer can be tedious, so we created a couple of options to automate it.
- Nutrient Optimiser will only emphasise foods and recipes that won’t further exacerbate any current nutrient imbalances. By prioritising foods that contain your prioritising foods that contain more of your priority nutrients, you automatically bring the ratios back into balance.
- To make things even more precise, Your Perfect Day Report in the Micros Masterclass shows which foods to increase and decrease to increase your diet quality score while remaining within the target ranges for each ratio.
The Importance of Balancing Nutrient Ratios
Similar-sized nutrients can compete for absorption and uptake in our body. Thus, if your supplementation or food fortification is excessive, you may adversely impact the absorption of other essential nutrients.
The good news is your micronutrient ratios are unlikely to be a significant concern unless:
- you use a lot of mineral supplements,
- consuming fortified processed foods (with high amounts of omega-6 in vegetable oils and iron fortification) or
- you’re consuming a lot of organ meats (which contain high amounts of copper),
Whole foods usually contain micronutrients in the forms your body understands and in ratios your body can quickly assimilate. While supplements are absorbed quickly as a bolus dose, your gut can modulate the nutrients it absorbs more easily from whole foods, letting the excess pass through and out the other end.
Our Optimal Nutrient Intakes have been created with the ideal nutrient ratios in mind. So, if you’re targeting the Optimal Nutrient Intakes, the micronutrient ratios will broadly look after themselves.
Synergistic and Antagonistic Nutrient Interactions
Your body requires an array of essential vitamins and minerals to thrive. While each has its unique role, they also work together to carry out specific functions.
Depending on the nutrients, these relationships can be:
- synergistic: where consuming one nutrient increases the effectiveness of another,
- antagonistic: where consuming one nutrient decreases the efficacy of another or
- both.
Potassium:Sodium Ratio – A Critical Balance
The potassium:sodium ratio is possibly your body’s most critical nutrient ratio.
Managing sodium and potassium is a huge priority for our body as the sodium-potassium pump is fundamental for our energy production and fluid balance.
Up to 40% of the body’s energy and 70% of the brain’s energy is devoted to managing the sodium-potassium pump alone!
An imbalance between your potassium and sodium intake is linked to various health issues like hypertension or elevated blood pressure. It’s not so much that sodium is bad and should be avoided. Instead, most people don’t consume enough potassium.
Sadly, few people meet the Adequate Intake (AI) level for potassium of 2.8 g/day (women) and 3.8 g/day (men). Even fewer get close to the ideal potassium: sodium ratio of 2:1, which is crucial for those managing your cardiovascular disease risk and tame elevated blood pressure.
While potassium and sodium are essential and have unique satiety responses, people with a higher potassium:sodium ratio eat less.
Potassium tends to be higher in minimally processed whole foods. Because it has a bitter taste and can interfere with popular blood pressure medication, it is not used to fortify ultra-processed foods.
The chart below shows the potassum:sodium ratio distribution in half a million days of data with an average of 1.3.
While athletes and people with adrenal fatigue need more sodium to stay hydrated, replenish the salt they lose in sweat and satisfy their salt demands, more sedentary people typically don’t need more sodium, especially if they consume processed foods that contain a lot of added sodium.
Sodium is one of the micronutrients for which we have a robust conscious taste. Hence, most people find it easy to meet their sodium requirement by adding salt to taste. If your food tastes too salty, you’ve likely had enough salt. Because we crave sodium intensely, it is often added to processed foods, so we buy and eat more.
However, it is theorised that our ancestors lived in an environment where salt was rare, and potassium was plentiful. Thus, we don’t have a strong taste or appetite for potassium. Hence, we must go out of our way to prioritise potassium in our food.
Omega 3:6 Ratio – Managing Inflammation
The other well-known micronutrient ratio is the omega-6:omega-3 ratio.
While a small amount of omega-6 fatty acids are essential, excessive amounts can cause inflammation and outnumber anti-inflammatory omega-3s. Omega 6 and omega 3 both compete for the same adsorption pathways, so if you’re getting excessive amounts of omega 6, you won’t absorb the critical omega-3 from your food.
Before the advent of agriculture, we would have likely obtained a similar amount of omega-3 fatty acids than omega-6. However, due to our heavy reliance on oils, grains, and animals fed grains today, the average omega-6: omega-3 ratio in the modern day is between 12:1 to 25:1.
Even if you avoid bread and vegetable oils, the omega-6:omega-3 ratio in the food system is still relatively high in many animal foods fed on grains, especially farmed beef, pork, fish, and poultry.
Epidemiological studies suggest that a low omega-3 fatty acid intake can contribute to mental illnesses like depression, schizophrenia, ADHD, personality disorder, and bipolar disorder. Other conditions like cardiovascular disease, hormone imbalance, and arthritis have also been linked to an imbalanced omega 6:3 ratio.
The chart below shows the omega 6:omega 3 ratio distribution in our Optimisers data, with an average of 5.8, which is greater than the target of less than 4.
Most people would benefit from consuming more high omega-3 foods, like fatty fish.
Zinc:Copper Ratio – Balancing Trace Minerals
Zinc and copper are essential microminerals that we need in small amounts. However, this ratio needs to be kept in balance.
Copper is vital for heart health, brain development, ATP production, antioxidant protection, collagen synthesis, and bone health.
Meanwhile, zinc boosts immunity and ensures your body stays healthy and protected. It is required for more than three hundred enzymatic reactions in the human body. We also need it for healthy sperm production, cell structure, regulated cellular communication, gene expression, and healthy growth and development in children.
Zinc also helps other nutrients to work in the body. For example, we need it to transport vitamin A into the bloodstream and absorb folate adequately. Too much zinc can interfere with copper absorption, leading to copper deficiency and inherent neurological ailments.
On the contrary, excessively high intakes of copper with low zinc have been attributed to several severe conditions, such as:
- Anxiety, panic attacks, general inner tension
- Depression
- Fatigue
- Hypothyroid symptoms (cold hands and feet, brain fog, dry skin)
- Overly sensitive, obsessive thinking
- Insomnia and interrupted sleep
- Premenstrual Syndrome (PMS)
- Estrogen Dominance and Premenstrual Dysphoric Disorder (PMDD)
- Anxiety
- Fluctuating blood sugar and inherent cravings
- Mood swings and paranoia
- Constipation
- Autism
- Racing heart and palpitations
- Adverse reaction to vitamins and minerals from ‘copper dumping’ caused by supplements
- Poor attention span and a spacey feeling
- Eating disorders (anorexia, bulimia, overeating)
- Accelerated ageing
- Yeast infections from candida and other fungi
- Copper toxicity
- Cramping and body aches
Because many relationships rely on the intricate balance of the zinc:copper relationship, the ideal zinc:copper ratio is thought to fall between 4:1 and 12:1. The chart below shows the distribution of the zinc:copper ratio, with an average of 10.8.
Iron:Copper Ratio – Supporting Red Blood Cells
Like our above nutrient relationships, iron and copper must balance to avoid deficiency or excess in one another. Studies have shown that copper excess can accumulate in the liver during iron deficiency and vice versa.
The body requires iron to synthesise red blood cells and transport oxygen into cells. Copper is also needed for healthy immune activity and enzyme production and to protect the body from heavy metals. Iron and copper are used to synthesise antioxidant enzymes like superoxide dismutase (SOD).
The suggested iron:copper ratio is somewhere between 10:1 and 15:1. The chart below shows the iron:copper ratio distribution, with an average of 13.2.
Calcium:Magnesium Ratio – Ensuring Bone Health
The human body needs adequate magnesium levels to properly use calcium, the most abundant inorganic mineral. Calcium is needed for muscle contraction, nerve impulse transmission, bone integrity, and maintaining a healthy pH. It is also an antihistamine.
Meanwhile, magnesium deficiency affects calcium metabolism and alters the levels of certain hormones that regulate calcium metabolism. Besides calcium utilisation, we need magnesium for over three hundred enzymatic reactions. It is required for muscle relaxation, fluid balance, hormone detoxification, and stress management, amongst other things.
High calcium intakes may interfere with magnesium status by reducing intestinal absorption and increasing urinary losses. On the other hand, magnesium deficiency is known to induce calcium deficiency.
Like zinc and copper, calcium and magnesium have a synergistic and antagonistic relationship. This means they also compete and interfere with each other’s functions if they are out of balance (i.e. if one is much higher than the other).
Magnesium may prevent calcium from contracting muscles when the ratio of magnesium to calcium is unfavourable. If calcium is too high and magnesium is too low, muscles may not be able to contract.
The chart below shows the distribution of calcium:magnesium ratio.
The average calcium:magnesium ratio is 3.4, suggesting that, while calcium is essential, most people need to prioritise magnesium-rich foods.
