February 2, by Stretch Rayner. There is very little evidence that eating a high protein diet increase cancer risk, as long as you eat a well balanced nutrient-dense diet and remove processed meats from the diet. If you would like some more information read this article from Chris Kresser. It's important to note that lean muscle meat and eggs are high in an amino acid called methionine, whereas foods like bone broth and fattier cuts of meat like shanks, ribs, chops, brisket and oxtail are high in an amino acid called glycine.
Consuming higher levels of glycine has been linked to health-promoting effects and increased life expectancy. High levels of methionine have been linked to increasing levels IGF-1 which can encourage cancer cell growth. It's important to maintain a healthy methionine-to-glycine ratio by consuming glycine-rich foods. Another reason why the type and quality of the meat you eat are essential to health and longevity. Protein is crucial in terms of our overall health, and there are many situations where either decreasing or increasing protein intake makes sense.
One size does not fit all and macronutrient calculation based on height, weight, age and gender is a very general guide check out if it fits your macros is not good enough and do consider current health and lifestyle factors. If you are an athlete and you are trying to train to improve sports performance strength, spend, power and recovery you are going to require ificantly more protein than the average person doing minimal exercise. Protein is the building blocks for lean muscle and plays an essential role in recovery and performance.
There has been an ongoing body of research investigating post-workout protein intake for athletes of all sports. The International Society of Sports Nutrition states :. Vast research supports the contention that individuals engaged in regular exercise training require more dietary protein than sedentary individuals.
Protein intakes of 1. When part of a balanced, nutrient-dense diet, protein intakes at this level are not detrimental to kidney function or bone metabolism in healthy, active persons. While it is possible for physically active individuals to obtain their daily protein requirements through a varied, regular diet, supplemental protein in various forms are a practical way of ensuring adequate and quality protein intake for athletes.
Different types and quality of protein can affect amino acid bioavailability following protein supplementation. Appropriately timed protein intake is an important component of an overall exercise training programme, essential for proper recovery, immune function and the growth and maintenance of lean body mass.
Under certain circumstances, specific amino acid supplements, such as branched-chain amino acids BCAA's , may improve exercise performance and recovery from exercise. Protein is the most important macronutrient when it comes to weight loss. One study took 39 adults and split into three groups . All three groups followed a specific diet and fitness regimen, the first was fed the recommended Regular Daily Amount RDA of protein, 0.
The second and third groups were fed 2xRDA amounts 1. Those eating the greater-than-RDA amounts of protein lost the most fat mass and maintained the most fat-free lean muscle mass. Two separate studies [9,10] supported this and showed that those eating a high protein diet lost 3. Protein stabilised blood sugar levels and has been shown to have a beneficial impact on a wide range of metabolic, cardiovascular, and inflammatory markers like C-reactive protein. A high protein breakfast tends to set the tone for the day and improve blood sugar regulation throughout the entire day.
Allostatic load le to lean muscle tissue breakdown. Studies show that high cortisol stress hormone blunts the desire for protein-rich foods and increases cravings for high-carb, high-fat foods that are very rewarding. Protein, especially collagen, are important in rebuilding tissue and can be crucial for those who going through stress and anxiety.
Why is this important? Your ability to digest and absorb nutrients form your diet is impacted and this can quickly lead to deficiencies, disease and chronic illness. Muscle atrophy can be a problem for the chronically ill and the elderly. High protein intake can help reduce that muscle breakdown. Strength is a predictor of life expectancy and hence maintaining muscle mass is critical to longevity. We should always be aiming to get out nutrients from whole food whenever possible.
Protein supplements can be useful for those who need higher intakes of protein, the above list. Protein powders also come with a high risk of food sensitivities and can often cause digestive issues if overused. There is no reason to be using a protein shake as a meal replacement, always eat real whole sources for your meals. A protein supplement should be seen as a supplement to a healthy diet. For more information on protein powders check out the article what is the best protein supplement for athletes. That said, these are just general guidelines and we suggest you experiment through the entire range to see what works best for you and your health goals.
Our protein intake should spread out across the day and not simply eaten at one big meal. We would recommend eating between g cals of protein per each main meal breakfast, lunch and dinner depending on your goals. Most people can benefit greatly from eating the right amount of protein for breakfast , we will talk about this more in a future blog post. articles on high protein diets.
