Eating too much protein, though, can lead to an imbalance which causes other problems in the body. Your brain may stay alert with protein, but it also needs carbohydrates for energy. According to the United States Department of Agriculture USDA , the RDA recommended daily intake for adult men and women is 0.

Also, consuming too much alcohol, processed sugar, and caffeine may affect the activities of neurotransmitters. Many hormones are formed from fat, but some are made of protein. Hormones are a slower form of communication than neurotransmitters, but they are still very important in maintaining your health.

These only come from food. Protein has unique abilities to bend, twist, and shape itself into the structures that allow enzymes to work. These little industrious workers are vital to brain health. They aid digestion so the brain gets the nutrients it needs, but they also work inside the brain too, breaking down plaque, creating neurotransmitters, and much more.

Get the best kind of enzymes in raw vegetables and fruits. RELATED: The Best Enzymes Come from Fresh, Raw Foods. Your body and your brain still need a mix of carbohydrates, protein, good fats, and plenty of vitamins, minerals, and antioxidants to keep functioning at an optimum level.

Most Americans actually eat way more protein than they need anyway. Most Americans eat too many carbs, too, especially the processed carbs that interfere with blood sugar and can damage the brain.

Going on protein diets which cuts out carbs entirely may cause more harm than good to the body. Balance is what the body needs, and healthy sources of all the macronutrients: fat, protein, and carbohydrates. Too much animal protein can put some strain on the kidneys and deliver much more fat than you want or need.

What other protein sources are there? Plants are not devoid of protein. Plant-based protein also reduces the strain on kidneys. Nuts, seeds, legumes, lentils, beans, and some whole grains are good sources of healthy proteins.

These protein sources also contain good fats. Carbohydrates are also important but should come from fresh fruits, vegetables, and whole foods as often as possible; not from candy, soft drinks, and processed foods.

Variety is important when it comes to nutrition. Your body needs a combination of essential amino acids to create muscle, connective tissue, hormones, enzymes, and neurotransmitters. Plant protein comes with different amino acid profiles. Mix up your sources throughout the week to get each essential amino acid you need in the right amount.

This made them wonder what additional opportunities to interact with other neurons this might provide. However, these have not identified any underlying mechanisms.

Overall, the work markedly advances our understanding of how the brain forms and stores memories, says the team. Kennedy suggests that an ideal way to preserve memory function would be to have drugs that target molecular activity at synapses.

Recent studies of the adult brain have uncovered many inactive synaptic connections. With such ideas in mind, they now plan to find out what happens to neurons when they supply or deprive them of netrin. Did you really see that pale face just now? What was that sound?

Medical News Today. A deficiency in protein intake can lead to a decrease in the production of these neurotransmitters, resulting in mood disorders such as anxiety and depression. She added that protein also promotes mental health by improving brain function. However, when incorporating protein into the diet, it is essential to keep in mind the quality and quantity of protein sources.

However, incomplete protein sources, such as plant-based proteins, may lack certain essential amino acids. Sharing that when proteins are broken down or digested, amino acids are left behind, Dr Naidoo listed some of her favorite foods rich in selected amino acids:.

Tryptophan: chickpeas; pasture raised chicken; grass- fed whole milk, canned wild tuna Tyrosine: avocados, sesame seeds, almonds, edamame Histidine: buckwheat, cauliflower, mushrooms, whole grains, nuts Arginine: salmon, almonds, brown rice, oats, chickpeas. BCCI secretary Jay Shah stresses that all centrally contracted players must participate in domestic red ball tournaments upon request from selectors, coach, and captain.

And, of course, omega fatty acids are essential for brain development and sustenance. Blueberries and other dark berries are rich in antioxidants, which protect against free radicals, making them one powerful brain food. They also help fight against degenerative changes in the brain and enhance neural functioning and communication.

Greens such as kale, spinach and broccoli are high in vitamin E as well as folate. Vitamin E helps protect cell membranes against free radicals. Free radicals are unstable molecules that attack cells within our body.

Some causes of free radicals include stress, pollution, radiation and processed food. Folate is also found in dark greens, and helps with normal brain development. Lean red meats, such as sirloin steak, are high in iron.

Iron aids in the production of neurotransmitters, as well as helps blood cells carry oxygen throughout the body, including the brain, aiding in attention and concentration. They are rich and creamy, and filled with omega fatty acids, as well as vitamin E.

Omega fatty acids are essential for cell growth and brain development, and vitamin E helps protect cell membranes from free radicals. Tomatoes are rich in lycopene, which is an antioxidant. Lycopene regulates genes that influence inflammation and regulates cell growth within the brain.

Whole grains contain complex carbohydrates, omega 3s, and B vitamins that all support normal brain function. The complex carbs provide a steady supply of energy that regulate mood and behavior, as well as aid in learning and memory.

Brown rice is full of B-vitamins, which help convert homocysteine, an amino acid, into important brain chemicals used for learning and creating new memories. Green tea is packed full of antioxidants that help protect against free radicals. Red wine contains an antioxidant called resveratrol.

This antioxidant helps improve blood flow to the brain and aids in attention and concentration. Remember: moderation is key when it comes to consuming alcohol. Dark chocolate is not only delicious, but it is packed full of antioxidants which, as we know, protect against free radicals.

Quinoa is high in complex carbs, iron and B vitamins. The brain uses up 20 percent of consumed carbohydrates which is a lot for being just 2 percent of your body mass.

Complex carbs are brain food. They provide a steady supply of energy needed for normal brain function. Iron helps blood oxygenate the body and is important for attention and concentration.

B vitamins help create brain chemicals that are important for creating memories. Our knowledgeable staff at UnityPoint Clinic - Neurology can answer your questions.

The amino acid L-Tryptophan, which can be found in poultry, fish, dairy and nuts, serves a precursor to serotonin. Eating foods rich in L-Tryptophan can help improve mood and help SSRIs and other antidepressants work more effectively. High sugar intake can have a number of adverse affects on all systems of your body, compromising both your physical and mental health.

Researchers are exploring the correlation between sugar and depression, and have theorized that a protein called BDNF may be the link.

BDNF plays an important part in the maintenance, growth and differentiation of nerve cells in the brain. Sugar suppress the activity of BDNF, which is typically already low in people who have depression. Increasing your intake of protein can help control your sweet tooth and stabilize blood sugar.

Protein bars, for instance, can be an effective snacking strategy to keep you satisfied between meals, however, pay attention to the sugar content in protein bars , as some protein bars can contain as much added sugar as a cookie. Protein, as a macronutrient, includes foods that are typically high in iron.

Low iron can cause anemia, and is the most common nutritional deficiency in the world. Anemia can leave you feeling fatigued, irritable and disengaged.

You may feel unmotivated or unable to sustain physical activity for long periods of time, which can contribute to feelings of depression.

Treating anemia will improve your mood and make it easier to function. Taking care of your mental health involves a variety of components, and nutrition can be an important part of it.

Protein is an essential nutrient for all processes in the body, including the optimal functioning of your brain.

The design and sampling have been detailed elsewhere 15 , Briefly, a multistage, random cluster process was used to select participants in nine provinces from northeast to southwest in China.

Two cities and four counties were randomly selected in each province based on their income levels as reported by the State Statistical Bureau in Four communities in each city or county and 20 households in each community were then randomly selected.

A total of 3, participants were included in the final analysis Figure 1. The survey was approved by the institutional review committees of the University of North Carolina at Chapel Hill and the National Institute of Nutrition and Food Safety, Chinese Center for Disease Control and Prevention.

Written informed consent was obtained from all participants. Dietary intake, at the household level and the individual level, was assessed using weighing methods in combination with h dietary recalls for three consecutive days at each survey. All foods and condiments for the home food inventory at the beginning and end of the 3-day survey period were measured using scales and recorded by trained interviewers.

Individual dietary data for the same three consecutive days were recorded for all household members and proportions of foods and condiments consumed at the household level were allocated to each individual Food and nutrient intake at the individual level was then calculated.

Nutrients and energy intake was calculated based on the China Food Composition The average annual protein intake from different sources of the surveys completed before the first cognitive assessment was also calculated. The assessment of energy intake has been validated by using the doubly labeled water method with a correlation efficient of 0.

A subset of the items from the Telephone Interview for Cognitive Status—modified was used to assess cognitive function The tool has been adopted in other population studies in China 21 , The cognitive screening included the immediate and delayed recall of a word list, counting backward from 20, and serial seven subtraction from for five times.

Each correctly recalled word was assigned a score of 1 and the total score for immediate and delayed recall ranged from 0 to For counting backward, a score of 2 was given to those counted backward correctly in the first try and one to those only counted backward correctly in the second try.

A score of 1 was assigned to each of the 5 serial subtractions and the total score for serial seven subtraction ranged from 0 to 5. The composite cognitive Z-score was computed by summing the scores of all three tasks and ranged from 0 to The composite cognitive Z-score was analyzed in Z-score and a higher score represented better cognitive function.

The change in composite cognitive Z-score was computed by subtracting the score at baseline from that at follow-up. Cognitive decline was defined as change in composite cognitive Z-score below the mean minus two standard deviations SDs.

This was retested by change in the composite cognitive Z-score below the mean minus 1. Height was measured using a freestanding stadiometer and weight was measured using an electronic scale.

Blood pressure was measured using a standard mercury sphygmomanometer by trained nurses. Three measurements were taken to the nearest two mmHg and the average of the last two was used.

All confounders at the time of the first cognitive measure were used in the analysis. Demographic socioeconomic factors included age, gender, region, education, smoking, and alcohol consumption were collected using a questionnaire. Physical activity was assessed based on hours per week spent in different occupational, household, transportation, and leisure-time activities, from which metabolic equivalent of task MET was calculated History of diabetes was also self-reported.

Data were expressed as frequency percentage and means ± SDs. ANOVA for continuous variables and the Chi-square test for categorical variables was performed to compare the difference of baseline characteristics across the quintiles of protein intake.

General linear regression models were used to obtain coefficients for the change in composite cognitive Z-score for quintiles 2—5 vs. The following models were tested: 1 age and gender; 2 model 1 plus education, urbanization, duration of follow-up, smoking, alcohol intake, physical activity, composite cognitive Z-score, diabetes, BMI, systolic, and diastolic blood pressure at baseline; 3 model 2 plus intake of energy, sodium, potassium, fat, and fiber.

We also calculated the linear trend by assigning participants the median intake within each quintile of the percentage of energy from dietary protein for each food source.

Logistic regression models were used to examine whether protein intakes from different food sources were associated with cognitive decline. Moderation analysis was used to test whether the association between protein intake and cognitive decline depended on other important factors.

Moderation analysis was conducted to examine whether the association of plant and animal protein intake with cognitive decline was modified by age, gender, education, urbanization, and follow-up duration. Sensitivity analysis was conducted to examine whether the association of the average annual protein intake of surveys completed before the first cognitive assessment with changes in cognitive Z-scores.

Analyses were performed using SAS version 9. and all P -values were two-sided. A total of 3, participants Individuals with a higher plant protein intake were more likely to have lower education, live in rural areas, currently smoke, and have higher physical and occupation activity levels compared to those with a lower plant protein intake.

An inverse association between plant protein intake and composite cognitive Z-scores at baseline was observed Tables 1 , 2. In contrast, higher animal protein intake was associated with lower energy intake, lower fiber intake, and higher sodium intake. There was a positive association between the animal protein intake and the composite cognitive Z-score at baseline Supplementary Table 1.

Participants consumed The main plant sources of protein were grains 8. The main animal sources of protein included red meat 1. During a median follow-up of 9 2—18 years, composite cognitive Z-score declined by 0.

The prevalence of cognitive decline defined by the cognitive change below mean minus 1. Protein intake from other plant foods was not significantly associated with change in composite cognitive Z-score.

Conversely, animal protein intake was positively associated with change in composite cognitive Z-score. The corresponding number for protein intake from poultry and fish was 0. Protein intake from red meat, dairy, or eggs was positively associated with change in composite cognitive Z-score before but not after adjustment for the intake of energy, fiber, sodium, potassium, and fat Table 3.

Table 3. Animal protein intake was positively associated with change in memory Z-score before but not after adjustment for confounders Supplementary Table 2. An inverse association between plant protein intake and change in subtraction Z-score was found before but not after adjustment for confounders.

This was consistent with cognitive decline as defined by cognitive change below mean minus 1. quintile 1 of plant protein intake: 1. Animal protein intake was not significantly associated with cognitive decline Supplementary Table 5. Table 5. Sensitivity analysis showed the average annual plant protein intake reported in surveys completed before the first cognitive assessment was inversely associated with change in composite cognitive Z-score during follow-up Supplementary Table 6.

This longitudinal study of community-dwelling older Chinese adults demonstrated that lower plant protein but higher animal protein intake was associated with a lower risk of cognitive decline. We found higher plant protein intake was associated with greater cognitive decline.

Our findings are supported by some studies from Europe demonstrating a positive association between plant protein intake and diabetes The harmful effect of high plant protein intake may be attributed to the deficiency of micronutrients in plant-based diets including vitamin B12 and iron, which are associated with a higher risk of cognitive impairment 26 — Furthermore, plant-based proteins have relatively low essential amino acids and leucine contents or even lack one or more of the essential amino acids when compared with animal-based proteins, such that, a higher plant protein intake is less likely to increase lean and skeletal muscle mass This may explain the inverse association between plant protein intake was associated and change in cognition.

Higher protein intake from grains was independently associated with accelerated cognitive decline. This may be due to the fact that grains contain relatively low quantities of essential amino acid lysine, of which lower intake may increase the risk of hypertension, diabetes and obesity 30 , 31 resulting in cognitive decline.

We found an inverse association between animal protein intake and cognitive decline. Our findings are also consistent with some studies of Japanese and Chinese populations demonstrating that animal protein intake was inversely associated with blood pressure 33 , Animal proteins usually contain all essential amino acids, and therefore may consist of optimal amino acid composition resulting in better metabolic health A recent longitudinal study demonstrates that an adequate methionine mainly from animal foods status may decrease the risk of dementia and brain atrophy We also found an inverse association between poultry protein intake and the risk of cognitive decline.

Our findings are supported by a prospective study demonstrating that higher poultry intake was associated with less cognitive decline over 6 years in older Swedish adults 7.

An optimal amino acid composition of dietary protein intake may help optimize amino acid metabolism and protect against dementia risks including obesity, diabetes, hypertension, and stroke A cross-sectional study of Chinese adults found that a higher total protein intake was associated with a higher likelihood of mild cognitive impairment Likely, we found higher total protein intake was associated with accelerated cognitive decline.

Notably, animal sources accounted for only Meanwhile, plant protein intake was inversely but animal protein intake was positively associated with change in composite cognitive Z-score suggesting the inverse association between total protein intake and cognition was driven by plant protein in our study.

This indicates that increasing the proportion of animal protein in populations with plant dominant diets may help protect against cognitive decline.

A recent study of US women and men demonstrated that higher plant protein intake and lower animal protein intake was associated with lower likelihood of cognitive decline 13 , but other studies showed that specific protein food sources were not significantly associated with cognitive function The conflicting findings between our study and Yeh et al.

may be due to the fact that the plant foods are dominant in our population, but animal foods are dominant in the US population. To our knowledge, this is the first longitudinal study to examine the association between protein intakes from different food sources with cognitive decline. Post Comment.

Sprite, as she became known at our house, was a tiny but fierce hummer with chest feathers that changed moment by moment from red to orange to gold. Just as the busyness of summer was ramping up, Sprite taught me to slow down and take notice of her many small beautiful things.

Hummingbirds have the largest heart of any animal for its size. And they have the fastest heart rate, beating at beats per minute. Of all the wild birds, hummingbirds have the biggest brains, accounting for 4.

Hummingbirds have amazing memories! And, they visit about 1, flowers each day. While hummingbirds are attracted to feeders filled with sugar water, they actually prefer whole food sources of sugar from flowers. Latin American mystics believe that when you spot a hummingbird, it signifies the soul of a loved one stopping by to say hello.
