How to go dairy-free in 6 easy steps: Your ultimate guide to kickstart your dairy-free journey. Food Allergies Can Be Fatal Anyone who experiences or knows someone who experiences a severe food allergy knows how serious it can be.
Certain foods can prove to be life-threatening, and these severe allergies are particularly prominent in young children. According to A new study claims that women who drink cow's milk could increase their risk of developing breast cancer by up to 80 percent compared to women who drink soy milk.
Unbiased by either soy or dairy Most American adults, and even children, believe they should aim for three servings of dairy a day—thanks to the US Dietary Guidelines. From a young age we are taught to believe that by devoutly consuming dairy on the daily, we will be protected from brittle bones and Bulletproof Coffee has been making a lot of tempting claims about its supposed health benefits for years.
However, they are not necessarily true, and in some cases outright wrong. Is there any evidence to support their claims? Before you fall for their pitch and Catch up on Part 1 of us breaking down this flawed, dairy-funded study, or dive right in here.
Proteomics is the study of the set of proteins produced in response to a wide variety of stresses in this case, exercise. The utilization of proteomics in human sports nutrition studies is an emerging science and is playing an important role in improving our scientific understanding of the complex interplay between exercise-and nutrition-related influences on immune and metabolic responses.
This study employed a randomized, double blind, placebo controlled, crossover design the most scientifically rigorous of study designs. All the participants had to avoid supplements and medications such as non-steroidal anti-inflammatory drugs with a potential to influence inflammation and immune function during the study period.
In addition, they also agreed to avoid foods and supplements containing astaxanthin during the week study other than what was provided including dietary salmon, trout, shrimp, and crayfish. Study participants were randomized to astaxanthin 8mgs — an amount known to significantly increase plasma astaxanthin in human subjects 30 and placebo which looked identical trials, with these supplements ingested daily for four weeks prior to running 2.
After the washout period, participants repeated all the same procedures using the counterbalanced supplement ie those who had taken astaxanthin in trial 1 now took the placebo in trial 2 and vice-versa. Further analysis revealed that most of these proteins were involved in immune-related functions such as immune defense responses, immune complement activation a part of the immune system that enhances complements the ability of antibodies and other immune cells to lock onto and destroy pathogens within cells , and humoral immunity the ability of B-cells to recognize and respond to pathogens circulating freely.
However, while IgM fully recovered after the hour post-exercise recovery period in the astaxanthin trial, it remained at low levels in the placebo trial, even after 24 hours of recovery see figure 3. A similar trend was also noted for another type of immune antibody called IgG, although the differences here were not quite large enough to be considered statistically significant.
The surprising finding from this study was that contrary to expectations, taking astaxanthin did not seem to reduce markers of muscle damage or inflammation. However, while some previous studies have suggested that astaxanthin might help in this respect, these studies used markers of oxidative damage and inflammation, rather than actually measuring amounts of damaged cell fragments directly using oxylipins as this study did.
In plain English, taking an astaxanthin supplement or increasing astaxanthin intake via diet will likely not reduce muscle inflammation and soreness after hard or prolonged training.
In particular, astaxanthin seems to mitigate the decline in the all-important IgM antibody response, which is the first line of defense when the body encounters a virus. An effective IgM response is important for preventing viruses entering the body from taking hold and causing infection and illness!
Given the above, astaxanthin-rich foods or supplementation may be a very useful tool for keeping your immune system in tip-top condition during periods of hard training or competition. There are a number of fish and shellfish that contain useful dietary levels of astaxanthin.
These include salmon, red trout, lobster, crab, shrimp, crawfish and red seabream. Of these foods, salmon is probably most accessible and affordable for most athletes. As per this study, a dose of around 8mgs of astaxanthin per day is recommended and you should allow a few weeks for blood and tissue levels to rise in order to experience the benefits.
When purchasing, look for a brand that uses natural astaxanthin derived from microalgae rather than synthetic forms of astaxanthin, which may be less biologically effective. Another alternative is a krill oil supplement provided the astaxanthin content is stated.

High Intensity Training. Particularly for those athletes engaging in HIIT, enjoying some light cardio on rest days can increase blood flow, helping to lessen muscle soreness and improve range of motion.
In addition to giving the body adequate time to rest and recover, athletes must invest energy in selecting and preparing nutritious foods to support a healthy lifestyle.
Unlike the average gym-goer, athletes require notable increases in calories and carbohydrates to compensate for their rigorous training routines. A balanced post-workout meal consists of high-quality protein and carbohydrate-rich vegetables.
Together, these nutrients work to support tissue and reduce muscle soreness. Consider more nourishing options alongside water, such as:. Even those athletes paying extra careful attention to a nutritious diet can come up short in certain vitamins and minerals.
High-quality, targeted supplements can fill these gaps and optimize training and performance outcomes. Understandably, an in-season football player has different performance goals and training routines than an off-season soccer player.
A professional athlete has a more rigorous routine than a high school intramural player. Supplementation, like the need for rest days, depends heavily on the athlete, the type and intensity of training, and their fitness and performance goals.
When it comes to exercise and supplementation, more is not always better. Moderation is the key to a sustainable healthy lifestyle. More than the average person, athletes must remain aware of the stress that rigorous training puts on the body and take steps to mitigate this damage.
Carefully planned workout routines, with appropriately active rest days, can lead to a high-performance athletic career. Coupled with nutrient-dense foods and targeted supplements, athletes can expect better exercise performance, less muscle soreness, and speedier muscle recovery.
Working out night and day, rejecting rest days, or continually skipping social outings to work out can actually be harmful to your health. Work out smarter, not harder, by following our key recommendations for diet, exercise, and supplementation.
Active rest days with light cardio are encouraged as a way to enhance circulation and aid in healing microtears. Eat foods rich in antioxidants and healthy fatty acids. A high-quality protein with a nice side of carbohydrate-rich veggies is the perfect post-workout meal.
To fill the gaps, choose some targeted supplements that lessen muscle soreness, speed recovery times, and improve aerobic performance.

Heinz Company Brands LLC. Carbohydrate was chosen as a control as CHO supplementation has not been demonstrated to enhance or impair the recovery from eccentric exercise [ 2728 ].
Supplements were consumed within a 2 min period after the ECC, and then immediately after the assessments at 6 h, as well as within 2 h prior to the 24 h assessment. To minimize the impact of diet, all subjects were given an example low antioxidant diet to follow for the day preceding and the day of the study See Additional file 1 : Table S1.
To assess dietary intakes between groups and determine compliance a 2 day dietary record was obtained over the study period and analyzed. To characterize the participants, height and weight were measured using standard techniques and body fat percentage, body fat mass, and fat-free mass were measured using the air displacement plethysmography technique BodPod, Cosmed, Chicago, IL.
Subjects reported to the lab after an overnight fast ~12 a. Assessments of peak isokinetic torque PIKT and peak isometric torque PIMT of the knee extensor muscles of the right leg, as well as perceived muscle soreness MS and thigh circumference measures were obtained prior to the performance of maximal ECCs of the knee extensors of the right leg, immediately after ECC, and at 1, 2, 6, and 24 h post-ECC Fig.
All measurements were obtained from the right leg on all study participants and all non-involved body parts were immobilized throughout all Cybex testing to remove superfluous movement. Both static and dynamic muscle actions were chosen as previous research has suggested the temporal response between muscle actions may differ [ 6 ], and dynamic muscle actions more closely mimic those often used in sport or occupational performance.
PIKT and PIMT were assessed using the HUMAC NORM Cybex ergometer which has been demonstrated to be a reliable ergometer [ 2930 ]. After 5 min of easy cycling ~1 kp on an ergometer Monark E; Vansbro, Swedenparticipants subsequently performed a warm up set of 3 repetitions on the Cybex.
PIMT was determined by using the best of 3 maximal isometric contractions of the knee extensors with the knee flexed at an angle of 90°. For isokinetic measurements, after a warm up set of 5 repetitions, subjects performed 1 set of 5 repetitions of isokinetic contractions of the knee extensors, through an individually determined range of motion ~90° at an angular velocity of 40° s The highest value obtained during the 5 repetitions was recorded and ranged from to ft.
of peak torque. The total warm up lasted approximately 7—10 min. As eccentric contractions may alter sarcomere length, and the optimal length for tension development [ 1 ], optimal joint angle, a surrogate for length, was recorded, amongst other variables obtained from the dynamometer.
Body position, approximate axis of rotation of the knee joint and dynamometer lever arm length were recorded and thus consistent for all trials for each volunteer. Verbal encouragement was provided during all contractions to ensure maximal effort and was consistent between sessions and participants.
The minimum eccentric torque needed to lower the arm and initiate the dynamometer was ~5 ft lb. Muscle soreness was evaluated using a visual analog scale VAS [ 31 ].
Subjects were seated with right leg in passive 90° of flexion at the beginning of the soreness evaluation and instructed to extend the knee of the right leg parallel to the floor to full extension.
Subjects then placed a mark at the point on the VAS corresponding to their perception of the soreness of the right quadriceps muscle. This was done both unweighted and weighted with a 5-kg mass suspended from the ankle.
Muscle soreness was quantified by using the measured distance mm from the left end of the continuum to the mark made by the subject. Additionally, a Gulick tape measure was used to quantify the circumference of the right thigh at the midpoint between the greater trochanter of the femur and the knee joint to assess for localized swelling.
This location was marked with a permanent marker as means of standardization and to maintain consistency during follow-up measurements. On the first day of testing, following baseline measures, subjects performed maximal eccentric contractions ECCs of the knee extensors of the right leg on a HUMAC NORM isokinetic dynamometer Boston, USA at an angular velocity of 40° s-1 through an 80° range of motion Fig.
To the initiate each ECC, subjects performed a brief concentric contraction against the dynamometer lever arm of approximately 5 ft lb. The knee extensors were relaxed at the end of each ECC, and during the recovery phase the relaxed leg was returned to the starting position by the dynamometer.
The dynamometer provides real-time feedback to monitor effort during the ECC. This protocol was chosen as it has been used previously, with success, to determine the impact of dietary interventions on muscle soreness and function [ 17 ].
Verbal encouragement was provided to ensure maximal effort in a consistent manner during all contractions for all participants. A one way analysis of variance ANOVA was used to compare baseline parameters between the three supplement groups.
To account for potential minor variations in baseline muscle function ie. PIMT, PIKTmuscle function was normalized to initial and represented as the change from baseline. Alpha was set, a priori, at 0. All data was presented as mean ± standard error of the mean SE.
No significant differences were observed for age, height, weight, percent body fat, fat free mass, and initial thigh circumference between groups Table 1. There were no significant differences between the groups at the start of ECC testing. There were no differences in vitamin A, vitamin C, potassium, sodium, calcium, and iron intake between groups Table 2.
When expressed as percent of baseline Fig. Data are mean ± SE. Peak isokinetic torque, also exhibited a significant drop in torque over time Fig.
All groups experienced a significant increase in unweighted and weighted muscle soreness following the ECC Fig. The Impact of Supplementation on Changes in Muscle Soreness and Swelling.
Collectively, the current findings support protein supplementation to enhance recovery of muscle function and the addition of antioxidants to act synergistically to reduce perceived muscle soreness, in the hours immediately following ECC exercise.
Thus, the combination of protein and antioxidants may be an important consideration in developing and implementing strategies to aid in muscle recovery during the acute h time period following a bout of exhaustive eccentric exercise.
For instance, the CrossFit games, wrestling tournaments, powerlifting competitions, tennis tournaments, etc. Thus, developing supplementation strategies to improve recovery and reduce muscle soreness, might improve performance in such settings.
In terms of aiding recovery of muscle function from resistance exercise or eccentric exercise, supplementation with protein or amino acids post-exercise has been demonstrated to enhance recovery [ 17192022 ]. Regarding isometric muscle function, previous work by Buckley and colleagues [ 17 ] found that consumption of whey protein hydrolysate resulted in a quicker recovery in peak isometric torque following ECC, with complete recovery at 6 h post exercise.
However, unlike the Buckley et al. study [ 17 ], and others [ 18 ], which found supplementation with protein completely restored and even surpassed baseline peak isometric torque [ 17 ], we did not find resolution of force within the same observed timeframe Fig.
Although total work between groups was not reported in these earlier studies, even concentric muscle force contractions are suppressed following high intensity work [ 32 ]. In any case and even though our measurements did not extend to 48 h post ECC, the pattern of our reported muscle function data Figs.
As muscle function, broadly defined, is impaired following ECC, the magnitude and temporal pattern may depend upon contraction type; specifically, static versus dynamic, and concentric versus eccentric [ 56 ]. Thus, in agreement with previous studies [ 18 ], the present study suggests protein supplementation following ECC does, in fact, improve recovery of dynamic muscle function.
Furthermore, previous research has demonstrated that supplementation with antioxidants derived from fruit improves recovery of muscle function following fatiguing eccentric exercise [ 789 ], though not all agree [ 34 ].
In the current study, using an antioxidant derived from anthocyanin extract from mixed berries, we found no synergistic effect of supplementing with both protein and antioxidants, or the antioxidant offered no obvious additional benefit beyond that of protein alone Figs.
In agreement, previous studies have also found no effect of antioxidant supplementation using either vitamin C or fruit, berry and vegetable concentrate on muscle recovery [ 101134 ].
In contrast, previous studies using either a berry or fruit derived antioxidant supplement demonstrate an interaction between groups with no clear direction of improved muscle function [ 9 ] or show enhanced recovery of muscle function with a pre-loading period prior to ECC [ 8 ].
Collectively, future work is needed to determine if optimal dosing strategy, types of antioxidants, may influence the impact of antioxidant supplementation on muscle function following fatiguing eccentric exercise.

Beets and, to a lesser extent, spinach and carrots, increase blood flow because of their nitrate content. Beets supply naturally occurring, nonsynthetic nitrates that are converted to nitric oxide, which increases vasodilation. Blood vessels relax and widen during vasodilation. With wider blood vessels, more oxygen-rich blood flows through the body and reaches muscles sooner; this allows muscles to work at a high intensity for longer periods of time. Increased blood flow also helps to dissipate the heat created during physical activity. Elite athletes have long tried to find ways to increase vasodilation, including through illegal substances. Consuming beets and beet juice currently is popular with athletes. And while there's been strong evidence that beets and beet juice improve athletic performance, more recent research has been less conclusive. Juicing beets leads to a greater concentration of the beneficial components, but requires an expensive at-home juicer. Clients can purchase packaged, store-bought juice, though this also can be pricey. Powdered beet supplements are available for athletes, but the jury is still out on their effectiveness. Diced beets can be added to salads, and roasted beets can make an excellent side dish. According to a Harvard study, cacao, the bean from which chocolate is made, is associated with increased blood flow because of the positive effect flavanols have on the nitric oxide system. There's some evidence that dark chocolate has benefits on performance as well, possibly via this mechanism. These foods are nutrient dense and easy to incorporate into the diet as snacks or sides. Some athletes may take large supplemental doses of vitamin C, which results in poor absorption. It's mostly lost in the urine and isn't supported by evidence. Turnips, beets, mustard greens, and asparagus are good sources and are very low in total calories. Nuts and seeds make great snacks and also can be added to main dishes and salads. They're calorically dense, so educating clients about appropriate serving size is important. Berries Berries are nutrient dense and antioxidant rich, as they contain both anthocyanins and flavonols. Smoothies made with frozen berries are common beverages among athletes because they make excellent and fast postworkout meals or snacks. Frozen berries also keep much longer than fresh berries. Berries are very low in calories and can be added to breakfast foods like pancakes, oatmeal, or yogurt. Tart cherries also are popular with athletes and can be eaten whole or juiced, and added to frozen desserts that are calorically dense for those with very high energy needs. Leafy Greens The antioxidant count and nutrient density of leafy greens is unmatched. The serving size of cooked greens is one-half cup. A hungry athlete easily can eat two cups in one sitting, therefore consuming four servings of antioxidants. Sautéed greens can be added to many meals like stir-fries, burritos, and wraps. Arugula is especially rich in nitrates, containing more than beets. Called salad rocket in Europe, this spicy, leafy green can be eaten raw in salads or added to tacos. Fiber Antioxidant-rich foods most often come packed with significant amounts of fiber. The benefits of fiber are clear and undisputed, but large amounts can be problematic for individuals who aren't used to eating several grams in one sitting. For example, too much fiber can negatively impact performance by moving stool through the gastrointestinal GI tract too fast during physical activity. Nevertheless, some athletes on plant-based diets consume upwards of g per day without GI issues. If a client has a low-fiber diet, gradually increase high-fiber foods to give the GI tract time to adjust. If GI distress is a concern for athletic clients, consider reducing the total number of grams of fiber consumed within the three to four days leading up to a big event. Counseling Athletes Athletes tend to be motivated and interested in nutrition, which can be both a plus and minus for dietitians who work with them. Often, advice must be accompanied with rationale related to performance. Athletes are influenced by a variety of factors including coaches, supplement manufacturers, employees at nutrition stores such as GNC, celebrity athletes with promotional contracts, and well-meaning family members. |
