Nutrient-Density and Cravings
Most of us have heard the term “nutrient-dense” before, but do we all actually understand what it means? Nutrient density technically means the number of nutrients per calorie of food – so it is the ratio of nutrient content to the total energy content in that food.
Imagine we are comparing a specific nutrient, let’s use iron here in the example of ½ cup cannellini beans compared to ½ cup lentils. First we would determine the iron content in each: ½ cup cannellini beans contains 4 mg of iron, while ½ cup lentils contains 3 mg of iron. Then we would determine the calorie content of each food: ½ cup white beans provides 100 calories, while ½ cup lentils provides 115 calories. The nutrient density of iron in cannellini beans is 0.04, and the nutrient density of iron in lentils is 0.03. So if we wanted to know, technically speaking, which is more nutrient-dense in terms of iron, cannellini beans or lentils, the answer would be cannellini beans, because the ratio is higher.
Foods that are nutrient-dense provide many different micronutrients (vitamins and minerals) and a moderate amount of calories. An example of a nutrient-dense food is a piece of wild-caught salmon. It is rich in anti-inflammatory omega-3 fatty acids, rich in protein, and provides the following micronutrients: Vitamin B12, Vitamin D, Potassium, Selenium, Vitamin B3, and Vitamin B6. On the other side of the spectrum would be an empty-calorie food, or a food that contains very little nutrients, but a moderate to high amount of calories. An example of this would be a bottle of soda, like cola. It provides about 140 calories, 39 grams of sugar, no fat, no protein, and no micronutrients aside from sodium. Typically, calorie-empty foods are naked carbohydrates that don’t contain fiber.
Why Do Nutrient-dense Foods Curb Cravings?
Nutrient-dense foods, rich in protein, fiber, and fat, are essential for blood sugar balance. Blood sugar (glucose) levels are regulated by our pancreas, an organ in the endocrine system. The endocrine system is responsible for producing dozens of hormones, which are essentially chemical messengers. These messengers travel through the blood to different organs and tissues in the body coordinating various functions. Examples of hormones include sex hormones like progesterone, testosterone, and estrogen, stress hormones like cortisol, thyroid hormones such as T4 and T3, hunger hormones such as leptin and ghrelin, and so many more.
When we eat a meal rich in carbohydrates, our body sends a signal to our pancreas to start producing insulin. Insulin’s responsibility is to lower blood glucose levels by telling the body to start storing glucose in the muscle and liver as energy. This is a beautifully engineered system, but it requires work on our part to function properly.
If we continually eat empty-calorie foods, void of micronutrients, phytonutrients, protein, fiber, and fat, our bodies start to go on a glucose/insulin roller coaster. The pancreas begins to pump out lots of insulin causing blood sugar to crash which greatly affects our mood and impacts hormones. This blood sugar roller coaster can cause us to lose our innate ability to sense when we are full and may lead to cravings.
While all of our meal plans at The Daily Dose are nutrient dense, these are some specifically supportive in blood sugar balance for those of you needing immediate help: Ketotarian ,Paleo, and Protein Forward. As you stabilize glucose levels you’ll be surprised to know that eating more carbohydrate-forward meals improves insulin sensitivity. When we restrict carbs, as in lower carb meal plans in the aforementioned plans, we’re applying a band-aid effect that helps lower glucose levels. But, it’s a momentary effect. To really achieve real insulin sensitivity, we need to be able to consume real food, whole food carbohydrate sources. That’s the true test. The human body was designed to tolerate carbs so if you don’t currently tolerate them (i.e., you gain 10 pounds just looking at a bowl of oatmeal and forget a small slice of birthday cake!), then starting off by gaining control of your glucose and insulin is a good first step. Don’t worry, eventually you’ll be able to enjoy our more carb – forward meals!
Key Nutrients to Prevent Cravings
While all micronutrients serve a purpose in the body, there are specific ones that might help to reduce cravings:
Vitamin B6, or pyridoxine: Vitamin B6 plays a really important role in helping the body to metabolize protein. When we eat foods rich in Vitamin B6 like chickpeas, tuna, salmon, potatoes, bananas, squash, and chicken, we are helping our bodies turn the protein from the food into energy. This vitamin is also essential for mood and the production of brain chemicals, called neurotransmitters. When we are lacking B6, we may not have the raw ingredients to build healthy, robust levels of these neurotransmitters which can lead to disturbances in mood. We may then start to feel depressed, worried, and sad and can turn to food as a coping mechanism.
Magnesium: Magnesium is a mineral that many Americans have suboptimal levels of which is largely due to the changes in farming and soil over the last few decades. Foods rich in magnesium include things like dark leafy greens, nuts and seeds, beans, edamame, and dark chocolate. Eating these foods can greatly help support healthy blood sugar levels and reduce insulin resistance. In addition to supporting blood sugar, magnesium is found to be very helpful for stress and insomnia. If our sleep quality is on point, we can help to control cravings that are caused by stress and fatigue from lack of sleep. (link to sleep article)
Chromium: Chromium is a trace element found in food such as brewer’s yeast, beef, and whole grains. Chromium has been studied for its beneficial effects on lowering blood glucose levels and improving insulin dysregulation.
Tyrosine: Tyrosine is an amino acid found in the body which plays a role in making brain chemicals called neurotransmitters. Healthy neurotransmitter levels are important for controlling mood and well-being. Regulating these can prevent stress craving and binge-eating. Foods rich in tyrosine include poultry, fish, red meat, sesame seeds, soy products, and dairy.
Taurine: Taurine is an amino acid that occurs naturally in the body but is also found in meat, fish, and eggs. Taurine is really important for maintaining electrolyte balance in the body and controlling cellular hydration. Sometimes we can develop cravings for foods when our electrolytes (potassium, sodium, magnesium, chloride, phosphate) are not balanced, and eating foods rich in taurine can help support this system.
L-theanine: L-theanine is an amino acid found in green tea, and in some varieties of mushrooms. L-theanine helps support anxiety and stress and improves sleep quality and the ability to fall asleep. L-theanine can be helpful in reducing stress-induced cravings.
