Postmenopause

So, yes, you can add moderate amounts (1–2 servings a day) of soy foods, such as tofu, soy milk, or edamame, to your diet. As an example, a good protein intake is about 1 gram of protein per kilogram per day. A woman who weighs 70 kg (or 154 pounds) needs approximately 70 grams of protein a day, of which soy can be a part (one serving of tofu has about 14 grams of protein). Isoflavone supplements, on the other hand, contain higher levels of isoflavones and are generally not needed. Rather, eat the whole food source if you are going to consume soy. Note that some people do have a soy intolerance, so be aware of how your body responds to soy products.

Briefly, adequate protein intake is necessary to support the increased production of antibodies for fighting infection. Insufficient protein intake decreases the resistance of body to microbes, parasites, and chronic diseases. In contrast, eating more protein than we need does not improve immune function (3).
Diet and health
Published in Sally Robinson, Priorities for Health Promotion and Public Health, 2021
As protein is the building material for the whole body, it is essential for growth and repair. In the UK, most people obtain plenty of protein from meat, milk, milk products such as cheese and yoghurt, and cereals such as wheat, rice and cereal products (Bates et al., 2014). Proteins are made up of amino acids. When we eat protein, it is digested/broken down into amino acids which are absorbed into the blood stream. These amino acids can re-form to make the type of protein, such as skin or hair, the body needs. The diet needs to contain a good range of amino acids to do this.
Associations of low-carbohydrate with mortality in chronic kidney disease

The advice on the optimal diet for general populations thus varied between guidelines. The diet strategy for the population with chronic kidney disease (CKD) was even more controversial. With an impaired glomerular filtration rate, the residual renal function is vulnerable to dietary patterns. An optimal diet can effectively prevent CKD from progression [15]. Traditionally, a high-protein diet accelerated renal deterioration by glomerular hyperfiltration and increasing proteinuria [16,17]. Other than the most studied protein intake, a diet with lower phosphate intake [18], supplementation of n–3 polyunsaturated fatty acids [19,20], restriction of salt intake [21] and high intake of fruits, vegetables and fiber [15,22] were recommended for CKD patients. However, the role of carbohydrate intake in CKD progression was poorly studied. The low-fat and low-carbohydrate diet recommended by WHO for the general population [3] made protein the primary energy source, while a low-protein diet was still the dominant guideline for patients with CKD. Therefore, the final proportion of carbohydrates, fat and protein in total energy intake remains to be investigated. It is unknown whether a low carbohydrate diet is appropriate in the CKD population. We conducted a prospective cohort study using data from the NHANES to examine the association between a low carbohydrate diet and all-cause mortality in the CKD population.

Proteins are derived from both animal and plant sources. Animal sources of protein include seafood, meats, poultry and eggs. The term ‘meats’ includes all forms of beef, pork, lamb, veal, goat and non-bird game. Poultry refers to all forms of chicken, turkey, duck, geese, guineas and game birds. Plant sources include nuts, seeds and soy products. Legumes (plants with seed pods that split into two halves, such as dry beans, peas, lentils and soybeans) can be considered both a plant source of protein and a vegetable.107,108 While both animals and plants act as sources of protein in the diet, they differ in the quantity and quality of protein they provide. Animal-based foods, in general, contain the highest amount of protein per unit of energy. Furthermore, protein from animal sources is considered the best quality of protein, as it provides all essential amino acids in the proper proportions.107
Rationale and Design for a Higher (Dairy) Protein Weight Loss Intervention That Promotes Muscle Quality and Bone Health in Older Adults with Obesity: A Randomized, Controlled Pilot Study

Intentional weight loss among older adults with obesity is controversial and inconsistently advised.A higher protein diet may be able to mitigate loss of lean mass and function during intentional weight loss.The DDYNAMO Study will assess the combined effects of a 6-month higher-protein, calorie restricted dietary intervention and low-intensity exercise in older adults with obesity and mild to moderate functional impairment on muscle quality, muscle composition, and bone mineral density, measured at 0, 6, and 18 months.The DDYNAMO study will address a gap in knowledge about treatments for obesity in older adults, assessing the feasibility of implementing an intensive weight loss intervention that combines higher protein intake, reduced calories, and low-intensity exercise.
