Blood Sugar

Fasting 70 to 90 normal

80 to 130 diabetes


1 to 2 hours after meal:

less than 140 normal

less than 180 diabetes


Pre-Meal (Baseline Glucose)

72 to 90 non-diabetic


A1C:

less than 5.7 normal

less than 7.0 diabetes


Normal Post-Meal Blood Sugar Levels for Non-Diabetics


1 hour after eating: Below 140 mg/dL


2 hours after eating: Below 120-130 mg/dL


3 hours after eating: Close to fasting levels (~80-100 mg/dL)



What High Post-Meal Glucose Could Indicate


1. If 2-hour glucose is still above 140 mg/dL → Possible impaired glucose tolerance (pre-diabetes)



2. If 3-hour glucose is still above 120 mg/dL → Your body might be taking longer than normal to clear glucose, possibly indicating:


Mild insulin resistance (even if fasting levels are normal)


Slower glucose metabolism due to thyroid function or stress hormones


A higher glycation rate, contributing to your slightly higher A1C

Calcium

  It is very important to get enough calcium in our diet to maintain good bone health and reduce the risk of osteoporosis.  For women 50 and older it is recommended to get 1200 mg per day along with Vitamin D to help with the absorption.  For me eating a plant-based diet, my calcium comes from leafy greens like kale, tofu, tempeh, chia seeds, beans, legumes, and nuts.  I started eating a little cottage cheese for a snack, but I have to take Lactaid pills since I have some lactose intolerance.  I downloaded an app from the Playstore (My Net Diary) to help me track my calcium and protein intake (we will talk about protein another day).  Needless to say,  I am only getting about 800 mg of calcium from my diet, which is not enough.  I do supplement with Citralcal Maximum Plus daily which contains 650 mg of calcium, vitamin D 1000 units, Zinc 5.5 mg, Copper 0.45, Maganese 1.15 mg.  I also take Vitamin K2 100 Mcg daily.  Vitamin K2 helps direc...

Sugar

Consuming too many added sugars can contribute to health problems such as weight gain and obesity, type 2 diabetes, and heart disease. Sugar  contributes to tooth decay and gum disease. Eating excessive amounts of sugar may increase your risk of developing certain cancers. Diets high in sugar increase inflammation in the body, may cause insulin resistance, both of which increase cancer risk. Consuming sugary products might give you a brief energy boost that is quickly followed by a sharp drop in blood sugar, leading to major fluctuations in energy levels. The American Heart Association recommends the following daily added sugar limits: Women : No more than  25 grams (6 teaspoons or about 100 calories) Men : No more than  36 grams (9 teaspoons or about 150 calories) These limits apply to  added sugars  (like those in processed foods, sugary drinks, and sweets), not naturally occurring sugars found in whole fruits, vegetables, and dairy. Cutting out sugar can lead...
