Excited to team up with Body Measures, to help share the importance of Nutrition & Mental Health. Think about it. Your brain is always “on.” It takes care of your thoughts & movements, your breathing and heartbeat, your senses — it works hard 24/7, even while you’re asleep. This means your brain requires a constant supply of fuel. That “fuel” comes from the foods you eat — and what’s in that fuel makes all the difference. Put simply, what you eat directly affects the structure and function of your brain and, ultimately, your mood.
What we eat can determine how we feel but how we feel can also determine what we eat. Food and the chemicals in our brains interact to keep us going throughout the day. It is important to eat a variety of healthy foods, as they have different effects on our brains. For example, carbohydrates increase serotonin, a brain chemical that has a calming effect. Perhaps that's why people often crave carbohydrate-rich foods when they are under stress. Protein-rich foods increase tyrosine, dopamine, and norepinephrine, which help to increase alertness. In addition, poor nutrition or lack of a variety of healthy foods can contribute to depression by limiting the availability of these specific nutrients.
Like an expensive car, your brain functions best when it gets only premium fuel. Eating high-quality foods that contain lots of vitamins, minerals, and antioxidants nourishes the brain and protects it from oxidative stress — the “waste” (free radicals) produced when the body uses oxygen, which can damage cells.
Unfortunately, just like an expensive car, your brain can be damaged if you ingest anything other than premium fuel. If substances from “low-premium” fuel (such as what you get from processed or refined foods) get to the brain, it has little ability to get rid of them. Diets high in refined sugars, for example, are harmful to the brain. In addition to worsening your body’s regulation of insulin, they also promote inflammation and oxidative stress. Multiple studies have found a correlation between a diet high in refined sugars and impaired brain function — and even a worsening of symptoms of mood disorders, such as depression.
It makes sense. If your brain is deprived of good-quality nutrition, or if free radicals or damaging inflammatory cells are circulating within the brain’s enclosed space, further contributing to brain tissue injury, consequences are to be expected. What’s interesting is that for many years, the medical field did not fully acknowledge the connection between mood and food.
How the foods you eat affect how you feel
Serotonin is a neurotransmitter that helps regulate sleep and appetite, mediate moods, and inhibit pain. Since about 95% of your serotonin is produced in your gastrointestinal tract, and your gastrointestinal tract is lined with a hundred million nerve cells, or neurons, it makes sense that the inner workings of your digestive system don’t just help you digest food, but also guide your emotions. What’s more, the function of these neurons — and the production of neurotransmitters like serotonin — is highly influenced by the billions of “good” bacteria that make up your intestinal microbiome. These bacteria play an essential role in your health. They protect the lining of your intestines and ensure they provide a strong barrier against toxins and “bad” bacteria; they limit inflammation; they improve how well you absorb nutrients from your food; and they activate neural pathways that travel directly between the gut and the brain.
Studies have shown that when people take probiotics (supplements containing the good bacteria), their anxiety levels, perception of stress, and mental outlook improve, compared with people who did not take probiotics. Other studies have compared “traditional” diets, like the Mediterranean diet and the traditional Japanese diet, to a typical “Western” diet and have shown that the risk of depression is 25% to 35% lower in those who eat a traditional diet. Scientists account for this difference because these traditional diets tend to be high in vegetables, fruits, unprocessed grains, and fish and seafood, and to contain only modest amounts of lean meats and dairy. They are also void of processed and refined foods and sugars, which are staples of the “Western” dietary pattern. In addition, many of these unprocessed foods are fermented, and therefore act as natural probiotics. Fermentation uses bacteria and yeast to convert sugar in food to carbon dioxide, alcohol, and lactic acid. It is used to protect food from spoiling and can add a pleasant taste and texture.
This may sound implausible to you, but the notion that good bacteria not only influence what your gut digests and absorbs, but that they also affect the degree of inflammation throughout your body, as well as your mood and energy level, is gaining traction among researchers. The results so far have been quite amazing.
What does this mean for you?
Start paying attention to how eating different foods makes you feel — not just in the moment, but the next day. Try eating a “clean” diet for two to three weeks — that means cutting out all processed foods and sugar. Add fermented foods like kimchi, miso, sauerkraut, pickles, or kombucha. You also might want to try going dairy-free — and some people even feel that they feel better when their diets are grain-free. See how you feel. Then slowly introduce foods back into your diet, one by one, and see how you feel.
When my patients “go clean,” they cannot believe how much better they feel both physically and emotionally, and how much worse they then feel when they reintroduce the foods that are known to enhance inflammation. Give it a try!
How Nutrients Help Your Brain
What we eat can determine how we feel but how we feel can also determine what we eat. Food and the chemicals in our brains interact to keep us going throughout the day. It is important to eat a variety of healthy foods, as they have different effects on our brains. For example, carbohydrates increase serotonin, a brain chemical that has a calming effect. Perhaps that's why people often crave carbohydrate-rich foods when they are under stress. Protein-rich foods increase tyrosine, dopamine, and norepinephrine, which help to increase alertness. In addition, certain healthy fats (omega-3 fatty acids) become part of the membranes of brain cells and control many brain processes. Poor nutrition or lack of a variety of healthy foods can contribute to depression by limiting the availability of these specific nutrients.
What Deficiencies Can Do
While nutrient deficiencies are usually rare, it's important to note the effect that certain deficiencies can have on mental health. Thiamine (vitamin B1), which is found in legumes, some seeds, and fortified grains, is necessary for maintaining your energy supplies and coordinating the activity of nerves and muscles. Thiamine deficiency can therefore lead to weakness, irritability, and depression. Folate (vitamin B9), which is found in leafy greens, legumes, and fortified grains, is essential for supporting red blood cell production, helping to prevent homocysteine build-up in your blood, and allowing nerves to function properly. Folate deficiency can result in depression, apathy, fatigue, poor sleep, and poor concentrationCustomers who purchase anything from Kali Kardia, Will get $10 off coupon for Body Measures. Opening July
